Importance: Recent changes in national and international lipid guidelines for reducing cardiovascular events recommend additional drugs, greater reductions, and lower targets for low-density lipoprotein cholesterol (LDL-C) if not attained with statins. The achievement of these targets with proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors has not yet been evaluated in a randomized clinical trial., Objective: To evaluate the 52-week safety and efficacy of lerodalcibep, a small anti-PCSK9-binding protein, in patients with cardiovascular disease (CVD) or who are at very high or high risk of CVD and requiring addition LDL-C-lowering treatment., Design, Setting, and Participants: This was a randomized, double-blind, placebo-controlled phase 3 trial. The trial was conducted at 66 clinics in 11 countries between April 23, 2021, and November 15, 2023. Individuals 18 years and older taking maximally tolerated statin therapy with LDL-C of 70 mg/dL or greater with CVD or 100 mg/dL or greater if at high risk of CVD were included., Interventions: Patients were randomized 2:1 to monthly 1.2-mL subcutaneous lerodalcibep, 300 mg, or placebo for 52 weeks., Main Outcomes and Measures: The safety analysis included all randomized patients. The co-primary efficacy end points were percent change from baseline in LDL-C at week 52 and the mean of weeks 50 and 52. Secondary efficacy outcomes included additional lipid apolipoprotein measures and achievement of guideline-recommended LDL-C targets., Results: Of 922 randomized participants (mean [range] age, 64.5 [27-87] years; 414 [44.9%] female; mean [SD] baseline LDL-C, 116.2 [43.5] mg/dL), 811 (88%) completed the trial. The mean (SE) placebo-adjusted reduction in LDL-C with lerodalcibep by modified intention-to-treat (mITT) analysis was 56.2% (2.2%) at week 52 and 62.7% (1.9%) for the mean of weeks 50 and 52; 49.7% (2.4%) and 55.3% (2.2%) by ITT with imputation using a washout model, and 60.3% (2.3%) and 65.9% (1.9%) by per-protocol analysis at week 52 and the mean of weeks 50 and 52, respectively (P < .001 for all). With lerodalcibep, 555 of 615 participants (90%) achieved both a reduction in LDL-C of 50% or greater and recommended LDL-C targets during the study. Treatment-emergent adverse events were similar between lerodalcibep and placebo, except for injection site reactions. These occurred in 42 of 613 participants receiving lerodalcibep (6.9%) compared to 1 of 307 receiving placebo (0.3%), were graded mild or moderate, and did not result in higher discontinuation of treatment, at 26 of 613 (4.2%) and 14 of 307 (4.6%), respectively. Sporadic in vitro antidrug antibodies were detected, which had no impact on free PCSK9 or LDL-C-lowering efficacy., Conclusions and Relevance: In this trial, lerodalcibep, a novel anti-PCSK9 small binding protein, dosed monthly and stable at ambient temperatures significantly reduced LDL-C in patients with CVD or at high risk of atherosclerotic cardiovascular disease with a safety profile similar to placebo. These results support long-term use of lerodalcibep in patients with CVD or at high risk of CVD who are unable to achieve adequate LDL-C reduction while receiving maximal tolerated statins alone., Trial Registration: ClinicalTrials.gov Identifier: NCT04806893.

Purpose of Review: Current guidelines for primary and secondary prevention of cardiovascular events in adults up to age 75 years are well-established. However, recommendations for lipid-lowering therapies (LLT), particularly for primary prevention, are inconclusive after age 75. In this review, we focus on adults ≥ 75 years to assess low-density lipoprotein-cholesterol (LDL-C) as a marker for predicting atherosclerotic cardiovascular disease (ASCVD) risk, review risk assessment tools, highlight guidelines for LLT, and discuss benefits, risks, and deprescribing strategies., Recent Findings: The relationship between LDL-C and all-cause mortality and cardiovascular outcomes in older adults is complex and confounded. Current ASCVD risk estimators heavily depend on age and lack geriatric-specific variables. Emerging tools may reclassify individuals based on biologic rather than chronologic age, with coronary artery calcium scores gaining popularity. After initiating LLT for primary or secondary prevention, target LDL-C levels for older adults are lacking, and non-statin therapy thresholds remain unknown, relying on evidence from younger populations. Shared decision-making is crucial, considering therapy's time to benefit, life expectancy, adverse events, and geriatric syndromes. Deprescribing is recommended in end-of-life care but remains unclear in fit or frail older adults. After an ASCVD event, LLT is appropriate for most older adults, and deprescribing can be considered for those approaching the last months of life. Ongoing trials will guide statin prescription and deprescribing among older adults free of ASCVD. In the interim, for adults ≥ 75 years without a limited life expectancy who are free of ASCVD, an LLT approach that includes both lifestyle and medications, specifically statins, may be considered after shared decision-making., (© 2024.

Background: The effectiveness of statin treatment to reduce coronary events and mortality has been hardly examined considering goals of LDL-C. We aimed to analyse such association in secondary cardiovascular prevention., Methods: Retrospective cohort analysis of electronic health records from the SIDIAP database, Catalonia-Spain. Recruitment period was from 2006 to 2017 and study period finished at the end of 2018. We included 54,175 people aged ≥35 years in cardiovascular secondary prevention starting statin treatment. We analysed the association of achieved LDL-C goals after statin initiation with coronary heart disease and all-cause mortality., Results: Mean age was 69 years and 20,146 (37.2%) were women. Coronary heart disease occurred in 5687 (10.5%) participants, and 10,676 (19.7%) persons passed away. Median follow-up lasted 5.7 years (interquartile range, 3.4-8.1). The coronary heart disease HRs (95% CI) for the LDL-C goals of 70-100, <70-55 and <55 mg/dL were .86 (.81-.92), .83 (.76-.9) and .8 (.72-.88), respectively. They were .89 (.83-.96) in the group with 30%-40% reduction and .86 (.8-.93) in the groups with 40%-50% and ≥50% reduction. We observed no association with mortality. We observed no relevant differences by sex or age., Conclusions: This population-level retrospective analysis of real-world data observed that treatment with statins is effective to achieve certain LDL-C goals and CHD reduction. The lack of significant difference between LDL-C goals needs confirmation in additional studies with real-world data. The LDL-C target should consider the magnitude of the decrease in coronary events., (© 2024 The Author(s).

Background: Menopause is associated with elevated cardiovascular risk due to the loss of the cardioprotective effect of oestrogens. Postmenopausal women are often prescribed hormone replacement therapy (HRT) in order to control menopause symptoms and correct hormone imbalances; however, HRT can impact serum lipids' concentrations. At present, data on the effect of the administration of medroxyprogesterone acetate plus conjugated equine oestrogens (MPACEE) on the lipid profile in females are uncertain, as the investigations conducted so far have produced conflicting results. Thus, we aimed to clarify the impact of MPACEE prescription on the serum lipids' values in women by means of a systematic review and meta-analysis of randomized controlled trials (RCTs)., Methods: We employed a random-effects model based on the DerSimonian and Laird method to determine the combined estimates of the intervention's impact on the lipid profile. The computation of the weighted mean difference (WMD) and its corresponding 95% confidence interval (CI) relied on the mean and standard deviation values from both the MPACEE and control group, respectively., Results: A total of 53 RCTs were included in the meta-analysis with 68 RCT arms on total cholesterol (TC), 70 RCT arms on low-density lipoprotein cholesterol (LDL-C) and triglycerides (TG), and 69 RCT arms on high-density lipoprotein cholesterol (HDL-C). Administration of MPACEE resulted in a significant reduction of TC (WMD = -11.93 mg/dL; 95% CI: -13.42, -10.44; p < .001) and LDL-C (WMD = -16.61 mg/dL; 95% CI: -17.97, -15.26; p < .001) levels, and a notable increase in HDL-C (WMD = 3.40 mg/dL; 95% CI: 2.93, 3.86; p < .001) and TG (WMD = 10.28 mg/dL; 95% CI: 7.92, 12.64; p < .001) concentrations. Subgroup analysis revealed that changes in the lipid profile were influenced by several factors: body mass index (for TC, HDL-C, TG), MPACEE dosages (for TC, LDL-C, HDL-C, TG), age (for TC, LDL-C, HDL-C, TG), durations of the intervention (for TC, LDL-C, HDL-C, TG), continuous/sequential administration of MPACEE (continuous for TC; sequential for LDL-C, TG) administration of MPACEE and serum lipids' concentrations before enrolment in the RCT (for TC, LDL-C, HDL-C, TG)., Conclusions: MPACEE administration can influence serum lipids' concentrations in females by raising HDL-C and TG levels and reducing LDL-C and TC values. Therefore, postmenopausal women who suffer from hypercholesterolaemia might benefit from this type of HRT., (© 2024 Stichting European Society for Clinical Investigation Journal Foundation.

Background: In the CLEAR (Cholesterol Lowering via Bempedoic Acid, an ACL-Inhibiting Regimen) Outcomes trial, treatment of statin-intolerant patients with bempedoic acid produced a 21% decrease in low-density lipoprotein cholesterol (LDL-C) relative to placebo and a 13% relative reduction in the risk of major adverse cardiovascular events., Objectives: This study sought to determine whether the relationship between LDL-C lowering and cardiovascular benefit achieved with bempedoic acid resembles that observed with statins when standardized per unit change in LDL-C., Methods: To compare the treatment effect of bempedoic acid with statins, the methodology of the Cholesterol Treatment Trialists' Collaboration (CTTC) was applied to outcomes among the 13,970 patients enrolled in the CLEAR Outcomes trial. The CTTC endpoint of "major vascular event" was a composite of coronary heart disease death, nonfatal myocardial infarction, fatal or nonfatal stroke, or coronary revascularization. HRs for CTTC-defined endpoints were normalized to 1 mmol/L differences in LDL-C levels between bempedoic acid and placebo groups., Results: A first major vascular event occurred in 703 (10.1%) patients in the bempedoic acid group and 816 (11.7%) patients in the placebo group (HR: 0.85; 95% CI: 0.77-0.94). When normalized per 1 mmol/L reduction in LDL-C, the HR was 0.75 (95% CI: 0.63-0.90), comparable to the rate ratio of 0.78 reported for statins in the CTTC meta-analysis. Normalized risk reductions were similar for bempedoic acid and statins for the endpoints of major coronary events, nonfatal myocardial infarction, and coronary revascularization., Conclusions: Cardiovascular risk reduction with bempedoic acid is similar to that achieved with statins for a given absolute magnitude of LDL-C lowering.

Purpose of Review: To study the effect of bempedoic acid on markers of inflammation and lipoprotein (a) to help determine if the drug would be useful to treat patients with elevated cardiovascular risks and residual cardiovascular risk despite optimal low-density lipoprotein cholesterol (LDL-C) levels., Recent Findings: Bempedoic acid is found to cause significant reduction in LDL-C and high-sensitivity C-reactive protein (hs-CRP) in various randomized clinical trials. Multiple meta-analyses have also found that bempedoic acid therapy leads to reduction in non-high-density lipoprotein cholesterol (non-HDL-C), total cholesterol (TC) and apolipoprotein B (ApoB) levels. However, it has minimal effect on lipoprotein (a) (Lp(a)) level., Summary: Bempedoic acid is a new lipid-lowering agent that inhibits enzyme ATP-citrate lyase in the cholesterol biosynthesis pathway. Major risk of cardiovascular events and its associated morbidity and mortality are proportional to LDL-C and inflammatory markers levels. It was found that bempedoic acid significantly lowers LDL-C, hs-CRP and other inflammatory markers levels. This drug could potentially be used in patients with elevated cardiovascular risk, in patients with residual cardiovascular risk despite attaining LDL-C goal and in statin intolerant patients., (Copyright © 2024 Wolters Kluwer Health, Inc.

Purpose of Review: Although the clinical benefit of reducing low-density lipoprotein cholesterol (LDLc) in patients with coronary artery disease (CAD) is well-established, the impact on plaque composition and stability is less clear. Our narrative review aimed to assess the clinical effects of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors on coronary plaque characteristics specifically focusing from atheroma progression to regression and stabilization., Recent Findings: The combination of statin therapy and PCSK9 inhibitors (evolocumab and alirocumab) promotes plaque stability in patients following an acute coronary syndrome. The GLAGOV study highlighted the relationship between achieved LDLc levels and changes in percentage atheroma volume. Similarly, the PACMAN-AMI study concluded that the qualitative and quantitative changes in coronary plaque were associated with the levels of LDLc. Assessing the severity of coronary artery stenosis and the extent of atherosclerotic burden by means of imaging techniques (e.g., IVUS, OCT and near-infrared spectroscopic) have significantly advanced our understanding of the benefits from promoting plaque regression and achieving to features of plaque stabilization through increasingly intensive lipid-lowering strategies., (© 2024.

Background: The effect of proprotein convertase subtilisin kexin type (PCSK9) inhibitors on blood lipids and major adverse cardiovascular events (MACEs) is still controversial for acute coronary syndrome (ACS) patients. This study aimed to evaluate the efficacy and safety of PCSK9 inhibitors for ACS patients., Methods: We searched the following databases until March 2023: PubMed, Embase, Cochrane, Web of Science, CNKI, Chongqing VIP Database and Wan Fang Database. Finally, all randomized controlled trials, retrospective studies and prospective studies were included in the analysis., Results: A total of 20 studies involving 48,621 patients were included in this meta-analysis. The results demonstrated that PCSK9 inhibitors group was more beneficial for ACS patients compared to control group (receiving statins alone or placebo). The meta-analysis showed: there was no significant difference in high density lipoprotein cholesterol between PCSK9 inhibitors group and control group (standard mean difference = 0.17, 95% confidence interval [CI]: -0.02 to 0.36, P = .08), while the level of low density lipoprotein cholesterol in PCSK9 inhibitors group was lower than that in control group (standard mean difference = -2.32, 95% CI: -2.81 to -1.83, P < .00001). Compared with the control group, the PCSK9 inhibitors group also decreased the levels of total cholesterol and triglycerides (mean difference = -1.24, 95% CI: -1.40 to -1.09, P < .00001, mean difference = -0.36, 95% CI: -0.56 to -0.16, P = .0004). Moreover, compared with the control group, PCSK9 inhibitors group could reduce the incidence of MACEs (relative risk [RR] = 0.87, 95% CI: 0.83-0.91; P < .00001). However, this study showed that the incidence of drug-induced adverse events in PCSK9 inhibitors group was higher than that in the control group (RR = 1.15, 95% CI: 1.05-1.25, P < .0001)., Conclusion: Although this study demonstrates that PCSK9 inhibitors have higher drug-induced adverse events, they can not only reduce low-density lipoprotein cholesterol levels but also reduce the incidence of MACEs simultaneously. However, these findings needed to be further verified through large sample, multicenter, double-blind randomized controlled trials., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Introduction: Chios Mastiha essential oil (CMO) is a natural product extracted from the resin of Mastiha, possessing antioxidant, anti-microbial, anti-ulcer, anti-neoplastic, and cholesterol-lowering capabilities in vitro, and its hypolipidemic effect was confirmed in animal studies. Yet, there are no randomized, placebo-controlled clinical studies in the literature regarding CMO's hypolipidemic effects in humans. A prospective, randomized, placebo-controlled study was designed to study the hypolipidemic effect of CMO capsules on healthy volunteers with elevated cholesterol., Methods: 192 healthy volunteers were screened and 160 of them with total cholesterol> 200 mg/dl participated in the study. They were randomized with a 2:1 ratio of receiving CMO capsules (200 mg mastiha-oil/capsule) and placebo for 8 weeks respectively. 113 patients received CMO and 47 were randomized in the control group, and all of them completed the follow-up period., Results: After 8 weeks of CMO administration, total and LDL cholesterol were significantly lower in the CMO compared to the placebo group 215.2 ± 27.5 vs 237.0 ± 27.9 mg/dl (p < 0.001) and 135.0 ± 26.1 vs 153.0 ± 23.3 mg/dl (p < 0.001) respectively. No gastrointestinal adverse events or liver or renal toxicity were reported. Additionally, in the CMO group total cholesterol was significantly decreased by 20.6 mg/dl (9%), LDL by 18.1 mg/dl (12%), triglycerides by 21.8 mg/dl (15%), and glucose by 4.6 mg/dl (5%) and HDL was increased by 2.4 mg/dl (5%), compared to their baseline values., Conclusion: The MASTIHA-OIL study showed the efficacy and safety of CMO in reduction of total and LDL cholesterol after 8 weeks of administration in healthy volunteers with elevated cholesterol levels., (Copyright © 2023 Hellenic Society of Cardiology.

Purpose of Review: In this review, we will discuss the data from early clinical studies of MK-0616 and summarize clinical trials of other oral proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors., Recent Findings: The success of PCSK9 inhibition with monoclonal antibody injections has fueled the development of additional therapies targeting PCSK9, including oral formulations, the most advanced of which is MK-0616. MK-0616 is a novel, orally administered macrocyclic peptide that binds to PCSK9 and inhibits binding of PCSK9 to the LDL receptor, thereby decreasing plasma levels of LDL-C. Clinical trial data on the safety and efficacy of MK-0616 are promising and report LDL-C-lowering efficacy comparable to that provided by injectable PCSK9 inhibitors. Ongoing and future studies of oral PCSK9 inhibitors in development will evaluate the safety, efficacy, and effectiveness of these agents and their potential role in preventing cardiovascular disease events., (© 2024.

Worsened lipid profiles were observed in chronic hepatitis C (CHC) patients during direct-acting antivirals (DAAs) treatment, among which combination drugs confounded the effect of individual ingredient on lipid. Tenofovir alafenamide (TAF) also worsened lipid profiles in HIV patients. Structural similarity between sofosbuvir (SOF) and TAF prompted us to investigate rapid increase in total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) in CHC patients treated with SOF-based DAAs. A retrospective study was performed to analyze 487 CHC patients receiving DAAs with SVR12. Relative risks on elevating TC and LDL-C were analyzed by logistic regression to determine SOF-based over non-SOF-based regimens. TC or LDL-C levels at baseline, week-4 and SVR12 were compared by Wilcoxon matched-pairs signed rank test. Week 4 or SVR12 to baseline ratios of serum TC or LDL-C between regimens were compared by Mann-Whitney's test. 487 patients were treated with Harvoni (SOF-based, 206 patients), Epclusa (SOF-based, 124 patients), Maviret (non-SOF-based, 122 patients), or Zepatier (non-SOF-based, 35 patients). At week 4 during drug treatment, Harvoni, Epclusa, and Maviret induced statistically significant elevation of TC and LDL-C, but Zepatier did not. SOF-based regimens had 2.72-fold higher relative risk (RR) causing 10% elevation of TC (95% CI 1.84-4.02, p < 0.001) and 2.04-fold higher RR causing 10% elevation of LDL-C (95% CI 1.39-3.01, p < 0.001) than non-SOF-based DAAs. SOF-based DAAs were associated with significantly larger amplitude of increases in TC and LDL-C than non-SOF-based DAAs during the initial 4 weeks of treatment, but the increases were not sustained to SVR12., (© 2022.

Background: Many patients at very-high atherosclerotic cardiovascular disease risk do not reach guideline-recommended targets for LDL-C. There is a lack of data on real-world use of non-statin lipid-lowering therapies (LLT) and little is known on the effectiveness of fixed-dose combinations (FDC). We therefore studied prescription trends in oral non-statin LLT and their effects on LDL-C., Methods: A retrospective analysis was conducted of electronic medical records of outpatients at very-high cardiovascular risk treated by general practitioners (GPs) and cardiologists, and prescribed LLT in Germany between 2013 and 2018., Results: Data from 311,242 patients were analysed. Prescriptions for high-potency statins (atorvastatin and rosuvastatin) increased from 10.4% and 25.8% of patients treated by GPs and cardiologists, respectively, in 2013, to 34.7% and 58.3% in 2018. Prescription for non-statin LLT remained stable throughout the period and low especially for GPs. Ezetimibe was the most prescribed non-statin LLT in 2018 (GPs, 76.1%; cardiologists, 92.8%). Addition of ezetimibe in patients already prescribed a statin reduced LDL-C by an additional 23.8% (32.3 ± 38.4 mg/dL), with a greater reduction with FDC [reduction 28.4% (40.0 ± 39.1 mg/dL)] as compared to separate pills [19.4% (27.5 ± 33.8 mg/dL)]; p < 0.0001. However, only a small proportion of patients reached the recommended LDL-C level of < 70 mg/dL (31.5% with FDC and 21.0% with separate pills)., Conclusions: Prescription for high-potency statins increased over time. Non-statin LLT were infrequently prescribed by GPs. The reduction in LDL-C when statin and ezetimibe were prescribed in combination was considerably larger for FDC; however, a large proportion of patients still remained with uncontrolled LDL-C levels., (© 2020.

Background & Aims: Children and adults with lysosomal acid lipase deficiency (LAL-D) experience cirrhosis and dyslipidemia from lysosomal accumulation of cholesteryl esters and triglycerides. Sebelipase alfa enzyme replacement therapy is indicated for individuals with LAL-D. We report final results from the phase III randomized ARISE study of sebelipase alfa in children aged ≥4 years and adults with LAL-D., Methods: The study included a 20-week, double-blind, placebo-controlled period; a 130-week, open-label, extension period; and a 104-week, open-label, expanded treatment period. In the open-label periods, all patients received intravenous sebelipase alfa every other week. The primary outcome was alanine aminotransferase (ALT) level normalization; aspartate aminotransferase (AST) levels, lipid parameters, liver histology, liver and spleen volume and fat content, and safety were also assessed., Results: Of 66 patients enrolled, 59 completed the study. Median (range) age at randomization was 13 (4.7-59) years. At the last open-label visit, ALT and AST levels had normalized in 47% and 66% of patients, respectively. Patients who switched from placebo to sebelipase alfa experienced sustained improvements in ALT and AST during the open-label periods that mirrored those observed in the sebelipase alfa group during the double-blind period. Median (IQR) percent changes in lipid levels included a 25% (39%, 6.5%) reduction in low-density lipoprotein cholesterol and a 27% (19%, 44%) increase in high-density lipoprotein cholesterol. Most adverse events during the open-label periods were mild to moderate in severity; 13 patients had infusion-associated reactions (serious in 1 patient). Six patients (9%) developed anti-drug antibodies., Conclusions: Early and rapid improvements in markers of liver injury and lipid abnormalities with sebelipase alfa were sustained, with no progression of liver disease, for up to 5 years., Clinical Trial Number: NCT01757184; EudraCT Number: 2011-002750-31 LAY SUMMARY: Sebelipase alfa is used to treat lysosomal acid lipase deficiency (LAL-D), a rare, inherited disease of lipid metabolism. We report the final results of the phase III ARISE clinical study, which show that replacement of the defective LAL enzyme with sebelipase alfa for up to 5 years allows adults and children 4 years of age and older to maintain their initial improvements in liver and cholesterol parameters over the long term, without worsening of liver disease., Competing Interests: Conflict of interest B.

Background: Aloe ferox is one of the most widely used medicinal plants today, with the most intense detoxifying action of all aloe species, being used in the treatment of various diseases, including obesity. Our study aimed to assess the efficacy of Aloe ferox in obesity treatment., Methods: The study sample included 20 Romanian persons with obesity treated with diet and Aloe ferox based supplements, and 20 Romanian matched controls treated with diet and a placebo. The treatment included 2 capsules/day (Aloe ferox 460 mg) for 2 weeks, followed by a 2-week break, repeated 3 times. The blood pressure (systolic and diastolic) and anthropometric parameters, such as body mass index (BMI), total cholesterol, and abdominal circumference, as well as the biochemical parameters, fasting blood glucose (FBG), uric acid, and lipid profile was evaluated at baseline and after 3 months., Results: After 3 months of Aloe ferox administration, significant differences between the study group and the control group were observed regarding BMI (P = .03), total cholesterol (P = .032), low-density lipoprotein cholesterol (LDLc) (P = .01) and FBG (P = .018). Also, between the initial clinical, anthropometric, and biological parameters and those after the administration of Aloe ferox in the study group, we obtained significant differences regarding BMI (P = .002), LDLc (P = .039), fasting glycemia (P < .001) and diastolic blood pressure (P = .006)., Conclusions: The administration of Aloe ferox to obese patients has been shown to achieve a significant reduction in body weight, BMI, LDLc, and FBG. These effects may be due to the laxative and detoxifying action of Aloe ferox components. As it can only be administered for limited periods due to side effects, further experimental and human studies of the efficacy of this plant in the treatment of obesity are needed., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2021 the Author(s).

Background: Variability in low-density lipoprotein cholesterol (LDL-C) response to statins is underappreciated. We characterised patients by their statin response (SR), baseline risk of cardiovascular disease (CVD) and 10-year CVD outcomes., Methods and Results: A multivariable model was developed using 183,213 United Kingdom (UK) patients without CVD to predict probability of sub-optimal SR, defined by guidelines as <40% reduction in LDL-C. We externally validated the model in a Hong Kong (HK) cohort (n = 170,904). Patients were stratified into four groups by predicted SR and 10-year CVD risk score: [SR1] optimal SR & low risk; [SR2] sub-optimal SR & low risk; [SR3] optimal SR & high risk; [SR4] sub-optimal SR & high risk; and 10-year hazard ratios (HR) determined for first major adverse cardiovascular event (MACE). Our SR model included 12 characteristics, with an area under the curve of 0.70 (95% confidence interval [CI] 0.70-0.71; UK) and 0.68 (95% CI 0.67-0.68; HK). HRs for MACE in predicted sub-optimal SR with low CVD risk groups (SR2 to SR1) were 1.39 (95% CI 1.35-1.43, p<0.001; UK) and 1.14 (95% CI 1.11-1.17, p<0.001; HK). In both cohorts, patients with predicted sub-optimal SR with high CVD risk (SR4 to SR3) had elevated risk of MACE (UK HR 1.36, 95% CI 1.32-1.40, p<0.001: HK HR 1.25, 95% CI 1.21-1.28, p<0.001)., Conclusions: Patients with sub-optimal response to statins experienced significantly more MACE, regardless of baseline CVD risk. To enhance cholesterol management for primary prevention, statin response should be considered alongside risk assessment., Competing Interests: NQ is a member of the most recent NICE Familial Hypercholesterolaemia & Lipid Modification Guideline Development Groups (CG71 & CG181).

The toxicity of certain novel perfluoroalkyl substances (PFCs) has attracted increasing attention. However, the toxic effects of sodium p-perfluorous nonenoxybenzene sulfonate (OBS) on the endocrine system have not been elucidated. In this study, OBS was added to the drinking water during the pregnancy and lactation of the healthy female mice at dietary levels of 0.0 mg/L (CON), 0.5 mg/L (OBS-L), and 5.0 mg/L (OBS-H). OBS exposure during the pregnancy and lactation resulted in the presence of OBS residues in the placenta and fetus. We also analyzed physiological and biochemical parameters and gene expression levels in mice of the F0 and F1 generations after maternal OBS exposure. The total serum cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) levels were significantly increased in female mice of the F0 generation. The androgen levels in the serum and the ovarian mRNA levels of androgen receptor (AR) also tended to increase after maternal OBS exposure in the F0 generation mice. Moreover, maternal OBS exposure altered the mRNA expression of endocrine-related genes in male mice of F1 generation. Notably, the serum TC and LDL-C levels were significantly increased in 8-weeks-old male mice of the F1 generation, and the serum high-density lipoprotein cholesterol (HDL-C) levels were decreased in 24-week-old male mice of the F1 generation. These results indicated that maternal OBS exposure can interfere with endocrine homeostasis in the F0 and F1 generations. Therefore, exposure to OBS during pregnancy and lactation has the potential toxic effects on the dams and male offspring, which cannot be overlooked.

Objectives: Guidance recommends statin treatment in familial hypercholesterolaemia (FH) to achieve at least a 50% reduction in low-density lipoprotein cholesterol (LDL-C). We assessed statin prescribing rates and LDL-C treatment goal attainment among individuals with FH in primary care., Methods: Using primary care electronic health records from the UK Clinical Practice Research Datalink, we identified adults with recorded diagnosis of FH, statin treatment and measures of LDL-C prior to (baseline) and 12 months after initiating statin treatment. The percentage change in LDL-C was determined, and then baseline and treatment characteristics were assessed by LDL-C treatment goal attainment., Results: Of 3064 adults (mean age 50.8 years) with recorded diagnosis of FH and repeat LDL-C measures, 50% reduction in LDL-C from baseline was attained in 895 individuals (29.2%) in 12 months. Compared with those who did not attain this goal, these people were predominantly women; they were older at time of FH diagnosis (53.4 years vs 49.7 years) and first statin treatment (53.2 years vs 49.2 years) and had higher pretreatment total cholesterol (8.20 (SD 1.38) mmol/L vs 7.57 (SD 1.39) mmol/L) and pretreatment LDL-C (5.83 (SD 1.36) mmol/L vs 5.25 (SD 1.40) mmol/L). A higher proportion of individuals who attained the treatment goal was prescribed high-potency and medium-potency statins (24.3% and 71.7% vs 20.2% and 69.3%, respectively)., Conclusions: Less than a third of individuals on statin treatment for FH in the community achieve recommended reductions in LDL-C. Greater awareness and optimisation of treatment for FH using higher-potency statins are needed., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Background: Dimethandrolone (DMA) and 11β-methyl-19-nortestosterone (11β-MNT) are two novel compounds with both androgenic and progestational activity that are under investigation as potential male hormonal contraceptives. Their metabolic effects have never been compared in men., Objective: Assess for changes in insulin sensitivity and adiponectin and compare the metabolic effects of these two novel androgens., Materials/methods: In two clinical trials of DMA undecanoate (DMAU) and 11β-MNT dodecylcarbonate (11β-MNTDC), oral prodrugs of DMA and 11β-MNT, healthy men received drug, or placebo for 28 days. Insulin and adiponectin assays were performed on stored samples. Mixed model analyses were performed to compare the effects of the two drugs. Student's t test, or the non-parametric Kruskal-Wallis test as appropriate, was used to evaluate for an effect of active drug versus placebo., Results: Class effects were seen, with decrease in HDL-C and SHBG, and increase in weight and hematocrit, with no statistically significant differences between the two compounds. No changes in fasting glucose, fasting insulin, or HOMA-IR were seen with either compound. There was a slight decrease in adiponectin with DMAU that was not seen with 11β-MNTDC. An increase in LDL-C was seen with 11β-MNTDC but not with DMAU., Discussion: There were no significant changes in insulin resistance after 28 days of oral administration of these novel androgens despite a mild increase in weight. There may be subtle differences in their metabolic impacts that should be explored in future studies., Conclusion: Changes in metabolic parameters should be carefully monitored when investigating androgenic compounds., (© 2021 American Society of Andrology and European Academy of Andrology.)

Importance: Dyslipidemia, the prevalence of which historically has been low in China, is emerging as the second leading yet often unaddressed factor associated with the risk of cardiovascular diseases. However, recent national data on the prevalence, treatment, and control of dyslipidemia are lacking., Objective: To assess the prevalence, treatment, and control of dyslipidemia in community residents and the availability of lipid-lowering medications in primary care institutions in China., Design, Setting, and Participants: This cross-sectional study used data from the China-PEACE (Patient-Centered Evaluative Assessment of Cardiac Events) Million Persons Project, which enrolled 2 660 666 community residents aged 35 to 75 years from all 31 provinces in China between December 2014 and May 2019, and the China-PEACE primary health care survey of 3041 primary care institutions. Data analysis was performed from June 2019 to March 2021., Exposures: Study period., Main Outcomes and Measures: The main outcome was the prevalence of dyslipidemia, which was defined as total cholesterol greater than or equal to 240 mg/dL, low-density lipoprotein cholesterol (LDL-C) greater than or equal to 160 mg/dL, high-density lipoprotein cholesterol (HDL-C) less than 40 mg/dL, triglycerides greater than or equal to 200 mg/dL, or self-reported use of lipid-lowering medications, in accordance with the 2016 Chinese Adult Dyslipidemia Prevention Guideline., Results: This study included 2 314 538 participants with lipid measurements (1 389 322 women [60.0%]; mean [SD] age, 55.8 [9.8] years). Among them, 781 865 participants (33.8%) had dyslipidemia. Of 71 785 participants (3.2%) who had established atherosclerotic cardiovascular disease (ASCVD) and were recommended by guidelines for lipid-lowering medications regardless of LDL-C levels, 10 120 (14.1%) were treated. The overall control rate of LDL-C (≤70 mg/dL) among adults with established ASCVD was 26.6% (19 087 participants), with the control rate being 44.8% (4535 participants) among those who were treated and 23.6% (14 552 participants) among those not treated. Of 236 579 participants (10.2%) with high risk of ASCVD, 101 474 (42.9%) achieved LDL-C less than or equal to 100 mg/dL. Among participants with established ASCVD, advanced age (age 65-75 years, odds ratio [OR], 0.63; 95% CI, 0.56-0.70), female sex (OR, 0.56; 95% CI, 0.53-0.58), lower income (reference category), smoking (OR, 0.89; 95% CI, 0.85-0.94), alcohol consumption (OR, 0.87; 95% CI, 0.83-0.92), and not having diabetes (reference category) were associated with lower control of LDL-C. Among participants with high risk of ASCVD, younger age (reference category) and female sex (OR, 0.58; 95% CI, 0.56-0.59) were associated with lower control of LDL-C. Of 3041 primary care institutions surveyed, 1512 (49.7%) stocked statin and 584 (19.2%) stocked nonstatin lipid-lowering drugs. Village clinics in rural areas had the lowest statin availability., Conclusions and Relevance: These findings suggest that dyslipidemia has become a major public health problem in China and is often inadequately treated and uncontrolled. Statins were available in less than one-half of the primary care institutions. Strategies aimed at detection, prevention, and treatment are needed.

Purpose of Review: Coronavirus Disease 2019 (COVID19) has caused significant global morbidity and mortality, especially in persons with underlying cardiovascular disease. There have been concerns that lipid-lowering therapy (LLT) increases angiotensin-converting enzyme 2 levels. Conversely, pleiotropic effects of statins can theoretically protect against severe COVID19 infection, supporting evidence from other respiratory illnesses in which statin use probably confers benefit., Recent Findings: There is an abundance of studies that show that statins are safe and potentially protect against severe COVID19 infection (critical illness and death), even when adjustment for potential confounders is undertaken. However, the evidence is limited to retrospective cohorts. The benefit for patients with diabetes is less clear. There is a paucity of evidence for other LLT agents. Available clinical guidelines recommend the ongoing use of LLT in patients with COVID19 (unless specifically contra-indicated) and the data from available studies support these., Summary: In patients with COVID19 infection, LLT should be continued. However, the current findings need substantiating in larger prospective clinical studies with specific examination of the possible mechanisms by which LLT confers benefit from COVID19., (Copyright © 2021 Wolters Kluwer Health, Inc.

Background & Aims: Previous randomized controlled trials (RCTs) have compared the effects of pure preparations of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in reducing metabolic syndrome (MetS) risk factors, but the results were inconsistent. The present study aimed to clarify whether EPA and DHA have differential effects on MetS features in humans., Methods: A systematic literature search was conducted in CNKI, PubMed, Embase and Scopus updated to February 2021. The mean changes in the characteristics of MetS were calculated as weighted mean differences by using a random-effects model. Thirty-three RCTs were included., Results: The results showed that both EPA and DHA were effective at lowering serum triglycerides (TG) levels. EPA supplementation decreased the serum levels of total cholesterol (TC) (WMD = -0.24 mmol/L; 95% CI, -0.43, -0.05 mmol/L), TG (WMD = -0.77 mmol/L; 95% CI, -1.54, -0.00 mmol/L) and low density lipoprotein-cholesterol (LDL-C) (WMD = -0.13 mmol/L; 95% CI, -0.25, -0.01 mmol/L), while DHA increased the serum levels of TC (WMD = 0.14 mmol/L; 95% CI, 0.03, 0.25 mmol/L), LDL-C (WMD = 0.26 mmol/L; 95% CI, 0.15, 0.38 mmol/L) and high density lipoprotein-cholesterol (HDL-C) (WMD = 0.07 mmol/L; 95% CI, 0.04, 0.09 mmol/L). Moreover, DHA increased the serum levels of insulin compared with EPA, especially in subgroups whose mean age was <60 years (0.43 mU/L; 95% CI: 0.04, 0.81 mU/L) and duration of DHA supplementation < 3 months (0.39 mU/L; 95% CI: 0.01, 0.77 mU/L)., Conclusions: The present meta-analysis provides evidence that EPA and DHA have different effects on risk factors of MetS., Competing Interests: Conflicts of interest None declared., (Copyright © 2021 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

Patients with chronic kidney disease (CKD) and end-stage renal disease suffer from increased cardiovascular events and cardiac mortality. Prior studies have demonstrated that a portion of this enhanced risk can be attributed to the accumulation of microbiota-derived toxic metabolites, with most studies focusing on the sulfonated form of p-cresol (PCS). However, unconjugated p-cresol (uPC) itself was never assessed due to rapid and extensive first-pass metabolism that results in negligible serum concentrations of uPC. These reports thus failed to consider the host exposure to uPC prior to hepatic metabolism. In the current study, not only did we measure the effect of altering the intestinal microbiota on lipid accumulation in coronary arteries, but we also examined macrophage lipid uptake and handling pathways in response to uPC. We found that atherosclerosis-prone mice fed a high-fat diet exhibited significantly higher coronary artery lipid deposits upon receiving fecal material from CKD mice. Furthermore, treatment with uPC increased total cholesterol, triglycerides, and hepatic and aortic fatty deposits in non-CKD mice. Studies employing an in vitro macrophage model demonstrated that uPC exposure increased apoptosis whereas PCS did not. Additionally, uPC exhibited higher potency than PCS to stimulate LDL uptake and only uPC induced endocytosis- and pinocytosis-related genes. Pharmacological inhibition of varying cholesterol influx and efflux systems indicated that uPC increased macrophage LDL uptake by activating macropinocytosis. Overall, these findings indicate that uPC itself had a distinct effect on macrophage biology that might have contributed to increased cardiovascular risk in patients with CKD.

Background It is unclear if statin therapy in midlife can restore low cardiovascular risk in hypercholesterolemic individuals. Methods and Results At baseline, we grouped 5687 MESA (Multi-Ethnic Study of Atherosclerosis) participants aged ≥50 years without clinical cardiovascular disease (CVD) by Adult Treatment Panel III statin treatment recommendation and statin treatment status. We used Cox regression to compare the risks for coronary heart disease and CVD between the untreated group with low-density lipoprotein cholesterol (LDL-C) <100 mg/dL (reference) and other groups, adjusting for CVD risk factors. We also grouped participants by LDL-C level (< or ≥100 mg/dL), coronary artery calcium score (0 or >0 Agatston units), and statin status (untreated or treated) with the untreated LDL-C <100 mg/dL and coronary artery calcium=0 Agatston units as the reference. There were 567 coronary heart disease and 848 CVD events over 15 years of follow-up. The hazard ratios (HRs) for coronary heart disease and CVD in the group with statin-treated LDL-C <100 mg/dL were 1.16 (95% CI, 0.85-1.58) and 1.02 (95% CI, 0.78-1.32), respectively. However, participants with coronary artery calcium >0 Agatston units, treated to LDL-C <100 mg/dL had HRs of 2.6 (95% CI, 1.7-4.2) for coronary heart disease and 1.8 (95% CI, 1.2-2.6) for CVD. Conclusions Individuals treated with statins to LDL-C <100 mg/dL had similar levels of risk for atherosclerotic CVD as individuals with untreated LDL-C <100 mg/dL. However, individuals with coronary artery calcium >0 Agatston units have substantially higher risks despite lipid-lowering therapy, suggesting that statin treatment in midlife may not restore a low-risk state in primary prevention patients with established coronary atherosclerosis.

Lipid goal achievement and statin consumption were estimated at extreme/very-high/high/moderate and low cardiovascular risk categories. In the cross-sectional study, 585 patients treated with statin therapy referring to the heart clinic of Birjand were recruited. Patients were classified and examined LDL-C values and the proportion reaching targets according to the American Association of Clinical Endocrinologists guideline. Three patterns of statin use (high/moderate/low-intensity statin therapy) in all patients were examined and attainments of LDL-C goal in cardiovascular risk groups have been demonstrated. Over half the populations (57.6%) were in the very-high CVD risk group. The results showed that the proportion of patients meeting total LDL-C goal values according to the guidelines was 43.4%. The frequency of patient had achievement LDL goal lower in high-intensity pattern (N = 13, 2.3%), compared with moderate (N = 496, 86.1%) and low-intensity patterns (N = 67, 11.6%). In general, LDL-C goal achievement was greatest with moderate-intensity statin use. LDL-C reduction after statin consumption was estimated about one-third of the studied population. It seems likely that the achievement of a therapeutic target for serum lipids such as LDL-C improved is far more cost-effective and would be able to reach the target LDL as well changing the type and intensity of statins.

Background: Adherence to medicines is low for a variety of reasons, including the cost borne by patients. Some jurisdictions publicly fund medicines for the general population, but many jurisdictions do not, and such policies are contentious. To our knowledge, no trials studying free access to a wide range of medicines have been conducted., Methods and Findings: We randomly assigned 786 primary care patients who reported not taking medicines due to cost between June 1, 2016 and April 28, 2017 to either free distribution of essential medicines (n = 395) or to usual medicine access (n = 391). The trial was conducted in Ontario, Canada, where hospital care and physician services are publicly funded for the general population but medicines are not. The trial population was mostly female (56%), younger than 65 years (83%), white (66%), and had a low income from wages as the primary source (56%). The primary outcome was medicine adherence after 2 years. Secondary outcomes included control of diabetes, blood pressure, and low-density lipoprotein (LDL) cholesterol in patients taking relevant treatments and healthcare costs over 2 years. Adherence to all appropriate prescribed medicines was 38.7% in the free distribution group and 28.6% in the usual access group after 2 years (absolute difference 10.1%; 95% confidence interval (CI) 3.3 to 16.9, p = 0.004). There were no statistically significant differences in control of diabetes (hemoglobin A1c 0.27; 95% CI -0.25 to 0.79, p = 0.302), systolic blood pressure (-3.9; 95% CI -9.9 to 2.2, p = 0.210), or LDL cholesterol (0.26; 95% CI -0.08 to 0.60, p = 0.130) based on available data. Total healthcare costs over 2 years were lower with free distribution (difference in median CAN$1,117; 95% CI CAN$445 to CAN$1,778, p = 0.006). In the free distribution group, 51 participants experienced a serious adverse event, while 68 participants in the usual access group experienced a serious adverse event (p = 0.091). Participants were not blinded, and some outcomes depended on participant reports., Conclusions: In this study, we observed that free distribution of essential medicines to patients with cost-related nonadherence substantially increased adherence, did not affect surrogate health outcomes, and reduced total healthcare costs over 2 years., Trial Registration: ClinicalTrials.gov NCT02744963., Competing Interests: I have read the journal’s policy and the authors of this manuscript have the following competing interests: PJ serves as unpaid member of steering group or executive committee of trials funded by Abbott Vascular, Astra Zeneca, Biotronik, Biosensors, St. Jude Medical, Terumo and The Medicines Company, has received research grants to the institution from Appili Therapeutics, Astra Zeneca, Biotronik, Biosensors International, Eli Lilly, The Medicines Company, and honoraria to the institution for participation in advisory boards and/or consulting from Amgen, Ava and Fresenius, but has not received personal payments by any pharmaceutical company or device manufacturer.

Background Few adults at high risk for atherosclerotic cardiovascular disease events use a PCSK9i (proprotein convertase subtilisin/kexin type 9 inhibitor). Methods and Results Using data from the US Veterans Health Administration, we identified veterans who initiated a PCSK9i between January 2018 and December 2019, matched 1:4 to veterans who did not initiate this medication over this time period (case-cohort study). Two cohorts of veterans were analyzed: (1) atherosclerotic cardiovascular disease, with a most recent low-density lipoprotein cholesterol (LDL-C) ≥70 mg/dL; and (2) severe hypercholesterolemia (ie, familial hypercholesterolemia or any prior LDL-C ≥190 mg/dL, with most recent LDL-C ≥100 mg/dL). Conditional logistic regression was used to analyze factors associated with PCSK9i initiation, adjusting for all factors, simultaneously. There were 2394 initiators and 9576 noninitiators in the atherosclerotic cardiovascular disease cohort (median LDL-C, 141 and 96 mg/dL, respectively; P <0.001). Factors associated with a higher likelihood of PCSK9i initiation included age 65 to <75 versus <65 years, highest versus lowest quartile of median area-level income, familial hypercholesterolemia, former statin use, and current ezetimibe use. PCSK9i initiation was lower among veterans of a race/ethnicity other than non-Hispanic White. There were 245 initiators and 980 noninitiators in the severe hypercholesterolemia cohort (median LDL-C, 183 and 151 mg/dL, respectively; P <0.001). Age ≥75 versus <65 years, history of chronic kidney disease, former statin use, and current ezetimibe use were associated with a higher likelihood of PCSK9i initiation. Conclusions Several patient-level factors, including age, sex, and race/ethnicity, were significantly associated with PCSK9i initiation, suggesting an unmet treatment need in several patient groups.

Background and Aims: Despite trial evidence, high intensity statins are underutilized in routine clinical practice. This study sought to assess the individual and joint contributions of the TRS2P score as a measure of residual risk and LDL-C levels to benefits from further LDL-C lowering in the TNT trial., Methods: A total of 9980 patients were divided into 4 groups based on TRS2P and LDL-C at baseline: median (7.2%, group 4), NNT 78 vs. 14 (p-interaction <0.0001)., Conclusions: Measures of residual risk as well LDL-C identify patients who remain at high risk despite statins with the combination identifying those who derive the greatest benefits from even modest additional LDL-C lowering. Attention to residual risk as well as LDL-C may further help to optimize guideline implementation., (Copyright © 2021 Elsevier B.V. All rights reserved.)

What Is Known and Objective: The purpose of this study was to investigate the relationships among nilotinib plasma trough concentration (C 0 ), low-density lipoprotein (LDL) cholesterol, and PCSK9 plasma concentration in 31 patients with chronic myeloid leukaemia., Methods: Plasma concentrations of nilotinib and PCSK9 were measured by high-performance liquid chromatography and enzyme-linked immunosorbent assays, respectively., Results and Discussion: LDL cholesterol concentrations at 1 month after nilotinib treatment were significantly increased compared with those before therapy. The mean C 0 (±SD) of nilotinib at 1, 2, and 3 months after nilotinib treatment were 645 ± 516, 902 ± 623, and 951 ± 1088 ng/mL, respectively. Mean PCSK9 concentrations at 3 months after nilotinib treatment were significantly higher than those at the start of therapy (320 vs 257 ng/mL, respectively, P = .019). When the change rate in the PCSK9 concentration induced by nilotinib was classified with a cut-off value of +40%, the change rate in LDL cholesterol in patients with a change rate in PCSK9 of ≥40% was significantly higher than that in patients with a PCSK9 change rate of <40% (67.1% vs 38.0%, P = .043); however, there were no differences in mean nilotinib C 0 ., What Is New and Conclusion: Nilotinib may lead to hypercholesterolaemia by increasing plasma concentrations of PCSK9 after indirect inhibition of mammalian target of rapamycin (mTOR) complex 1. In addition, certain patients seem to have high sensitivity for nilotinib in a signalling cascade of the PI3K/Akt/mTOR pathway, despite low plasma concentrations of nilotinib. Consequently, nilotinib-induced hypercholesterolaemia could not be predicted based on the plasma concentration of nilotinib., (© 2020 John Wiley & Sons Ltd.)

Background: Nonalcoholic fatty liver disease (NAFLD) is a highly prevalent chronic liver disease characterized by excess accumulation of fat in hepatocytes. Because no drug has been approved for NAFLD treatment, this work analyzed the effects of agents resulting from 2 research hotspots, metabolic target agents, and natural plant drugs, on NAFLD with network meta-analysis., Methods: Public databases were searched through August 14, 2020. Randomized controlled trials that compared obeticholic acid, elafibranor, cenicriviroc, selonsertib, curcumin, silymarin, and resveratrol to placebo were included. Liver pathology improvement, hepatic biochemical indicators, and lipid metabolism indicators were analyzed., Results: Thirty-five studies were included in the meta-analysis. Obeticholic acid was found to significantly increase the frequency of liver biopsy improvement compared to placebo (OR: 2.10; 95% CI: 1.60, 2.77). The ranking results among the hepatic biochemical indicators showed that obeticholic acid (94.9%) and elafibranor (86.3%) have a relative advantage in reducing alanine aminotransferase (ALT) levels, and obeticholic acid also had an advantage (95.4%) in reducing aspartate aminotransferase (AST) levels. Considering lipid metabolic indicators, elafibranor (expSMD: 0.01; 95% CI: 0.00, 0.05; SUCRA: 100%), and obeticholic acid (expSMD: 0.48; 95% CI: 0.28,0.84; SUCRA: 75.6%) significantly reduced triglyceride (TG) levels compared with placebo; moreover, obeticholic acid, but not elafibranor, caused a serious increase in total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) levels and a decrease in high-density lipoprotein cholesterol (HDL-C) levels., Conclusions: Novel metabolic targeted agents generally have better effects than natural plant drugs, especially obeticholic acid, and elafibranor. However, obeticholic acid showed serious adverse effects such as increasing LDL-C levels and decreasing HDL-C levels. Curcumin showed potential advantages for NAFLD but lacked statistical significance., Competing Interests: The authors have no conflicts of interests to disclose., (Copyright © 2021 the Author(s).

Background: Recent international guidelines have lowered recommended target levels of low-density lipoprotein cholesterol (LDL-C) for patients at very high risk for major adverse cardiovascular events (MACE). However, uncertainty persists whether additional benefit results from achieved LDL-C levels below the conventional targets. Inferences from previous analyses are limited because patients who achieve lower versus higher LDL-C on lipid-lowering therapy differ in other characteristics prognostic for MACE and because few achieved very low LDL-C levels. To overcome these limitations, we performed a propensity score-matching analysis of the ODYSSEY OUTCOMES trial (Evaluation of Cardiovascular Outcomes After an Acute Coronary Syndrome During Treatment With Alirocumab) which compared alirocumab with placebo in 18 924 patients with recent acute coronary syndrome receiving intensive or maximum-tolerated statin treatment., Methods: Patients on alirocumab were classified in prespecified strata of LDL-C achieved at 4 months of treatment: <25 (n=3357), 25 to 50 (n=3692), or >50 mg/dL (n=2197). For each stratum, MACE (coronary heart disease death, nonfatal myocardial infarction, ischemic stroke, or hospitalization for unstable angina) after month 4 was compared in patients receiving placebo with similar baseline characteristics and adherence by using 1:1 propensity score matching., Results: Across achieved LDL-C strata of the alirocumab group, patients differed by baseline LDL-C, lipoprotein(a), use of intensive statin therapy, study medication adherence, and other demographic, medical history, biometric, and laboratory criteria. After propensity score matching, characteristics were similar in corresponding patients of the alirocumab and placebo groups. Treatment hazard ratio, 95% CI, and absolute risk reduction (number per 100 patient-years) for MACE were similar in those with achieved LDL-C <25 mg/dL (hazard ratio, 0.74 [95% CI, 0.62-0.89]; absolute risk reduction, 0.92) or 25 to 50 mg/dL (hazard ratio, 0.74 [95% CI, 0.64-0.87]; absolute risk reduction, 1.05). Patients with achieved LDL-C >50 mg/dL had poorer adherence and derived less benefit (hazard ratio, 0.87 [95% CI, 0.73-1.04]; absolute risk reduction, 0.62). No safety concerns were associated with a limited period of LDL-C levels <15 mg/dL., Conclusions: After accounting for differences in baseline characteristics and adherence, patients treated with alirocumab who achieved LDL-C levels <25 mg/dL had a reduction in the risk of MACE that was similar to that of patients who achieved LDL-C levels of 25 to 50 mg/dL.

The choice of lipid-modifying treatment is largely based on the absolute level of cardiovascular risk and baseline lipid profile. Statins are the first-line treatment for most patients requiring reduction of low-density-lipoprotein cholesterol (LDL-C) and ezetimibe and proprotein convertase subtilisin/kexin type 9 inhibitors can be added to reach LDL-C targets. Statins have some adverse effects that are somewhat predictable based on phenotypic and genetic factors. Fibrates or omega-3 fatty acids can be added if triglyceride levels remain elevated. The RNA-targeted therapeutics in development offer the possibility of selective liver targeting for specific lipoproteins such as lipoprotein(a) and long-term reduction of LDL-C with infrequent administration of a small-interfering RNA may help to overcome the problem of adherence to therapy.

Background: There is an incomplete understanding of the prevalence and predictors of attainment of low-density lipoprotein cholesterol (LDL-C) goal after myocardial infarction (MI)., Aim: To evaluate the prevalence of achievement of LDL-C goal of 70 mg/dL, to identify the baseline features associated with suboptimal lipid control, and to assess the use of LDL-C-lowering drug therapies (LLT) beyond the first year after MI., Methods: The EYESHOT Post-MI was a prospective, cross-sectional, Italian registry, which enrolled patients presenting to cardiologist 1 to 3 years after MI. In this retrospective post-hoc analysis, patients were categorized in 2 groups according to the achievement or not of the LDL-C goal of 70 mg/dL. Univariable and multivariable logistic regression analyses were performed to identify the baseline features associate with LDL-C≥70 mg/dL., Results: The study population included 903 patients (mean age 65.5 ± 11.5 years). Among them, LDL-C was ≥70 mg/dL in 474 (52.5%). Male sex ( P = 0.031), hypertension ( P = 0.024), prior percutaneous coronary intervention ( P = 0.016) and high education level ( P = 0.008) were higher in the LDL-C <70 group. At multivariable analysis, low education level was an independent predictor of LDL-C≥70 mg/dL (OR:1.582; 95%CI, 1.156-2.165; P = 0.004). Conversely, hypertension increased the probability to achieve the LDL-C goal (OR:0.650; 95%CI, 0.443-0.954; P = 0.028). Among off-target patients, LLT was not modified in the majority of cases (67.3%), intensified in 85 (18.6%), and actually reduced in 63 patients (13.8%)., Conclusions: In patients presenting to cardiologists 1 to 3 years from the last MI event, LDL-C is not under control in a large proportion of patients, particularly in those with a low education level or without hypertension. LLT is underused in this very-high-risk setting.

β-Glucan has been reported for its health benefits on blood lipids in hypercholesterolaemic individuals for years. However, people have paid little attention to the effects of β-glucan in populations with mild hypercholesterolaemia as well as the various delivering matrices. Our objective was to perform a meta-analysis to analyse the effects of β-glucan with different delivering matrices in mildly hypercholesterolaemic individuals. After conducting a comprehensive search in Web of Science, PubMed, Scopus and Cochrane Library, a total of twenty-one randomised controlled trials involving 1120 participants were identified to measure the pooled effect. The overall results indicated that consuming a dose of ≥3 g/d of β-glucan for at least 3 weeks could significantly reduce total cholesterol (TC) (-0·27 mmol/l, 95 % CI -0·33, -0·21, P < 0·001) and LDL-cholesterol (-0·26 mmol/l, 95% CI -0·32, -0·20, P < 0·001) compared with the control group in mildly hypercholesterolaemic individuals, while no significant difference was observed in TAG (-0·03 mmol/l, 95% CI -0·11, 0·06, P = 0·521) and HDL-cholesterol (0·01 mmol/l, 95% CI -0·03, 0·04, P = 0·777). There was evidence for modest unexplained heterogeneity in the meta-analysis. In conclusion, β-glucan can significantly reduce risk factors like TC and LDL-cholesterol for CVD in mildly hypercholesterolaemic individuals; furthermore, it appears that the effects of food matrices with both 'solid products' and 'liquid products' where β-glucan was incorporated into were ranked as the best way to exert its beneficial properties, while 'liquid' and 'solid' products were ranked as the second and third positions, respectively.

Purpose: To evaluate the potential association between the lowering of low-density lipoprotein cholesterol (LDL-C) with contemporary lipid-lowering medicines and cognitive function., Methods: Randomized controlled trials (RCTs) in databases including PubMed, Embase, and the Web of Science and all databases in the Cochrane Library and ClinicalTrials.gov were collected from inception to January 1, 2020. The cognitive function of patients receiving proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, statins and ezetimibe was evaluated using meta-analysis., Results: A total of 2910 studies were obtained from databases and other sources. Thirty-three studies were selected by screening, including 11 studies on alirocumab, 9 studies on evolocumab, 11 studies on statins and 2 studies on ezetimibe. In our study, a total of 128,691 patients with no cognitive impairment were divided into an intervention group (66,330 patients) and a control group (62,361 patients). The data were subjected to a random-effects model or a fixed-effects model for meta-analysis. The contemporary lipid-lowering medicines significantly reduced LDL-C in terms of both percentage (WMD: -45.06%, 95% CI -50.12% to -40.00%, P < 0.001) and absolute value (WMD: -64.01 mg/dL, 95% CI -72.25 to -55.78, P < 0.001). Compared with the control group, patients receiving treatment with contemporary lipid-lowering medicines did not show a significant difference in the rate of neurocognitive disorder (RR: 1.02, 95% CI 0.90 to 1.16, I 2  = 0.0%, p = 0.696). Subgroup analysis was performed according to the intervention and LDL-C stratification. The result of this subgroup analysis was consistent with the main findings. Regarding global cognitive performance, no difference in major cognition was found among the pooled data (SMD: 0.02, 95% CI -0.01 to 0.04, P = 0.002), except for psychomotor speed (SMD: 0.09, 95% CI 0.02 to 0.16, P = 0.0024)., Conclusions: Contemporary lipid-lowering medicines were not associated with cognitive impairment in RCTs. A low LDL-C level did not influence the incidence of cognitive disorder or global cognitive performance.

Background: Despite advances in the development of lipid-lowering therapies, clinical trials have shown that a significant residual risk of cardiovascular disease persists. Specifically, new drugs are needed for non-responding or statin-intolerant subjects or patients considered at very high risk for cardiovascular events even though are already on treatment with the best standard of care., Results and Conclusions: Besides, genetic and epidemiological studies and Mendelian randomization analyses have strengthened the linear correlation between the concentration of low-density lipoprotein cholesterol (LDL-C) and the incidence of cardiovascular events and highlighted various novel therapeutic targets. This review describes the novel strategies to reduce the levels of LDL-C, non-HDL-C, triglyceride, apolipoprotein B, and Lp(a), focusing on those developed using biotechnology-based strategies.

Background: Recent experimental and clinical studies have suggested that Hwangryunhaedok-tang (HHT), an herbal formula, could improve the lipid profiles in patients with dyslipidemia. This systematic review aimed to evaluate the effectiveness and safety of HHT monotherapy or adjunctive HHT therapy with conventional lipid-lowering drugs in managing dyslipidemia., Methods: Twelve English, Korean, Chinese, and Japanese databases were comprehensively searched from their inception to January 2020. Randomized controlled trials (RCTs) using HHT monotherapy or adjunctive HHT therapy for dyslipidemic patients were included. The primary outcome was the low-density lipoprotein cholesterol (LDL-C) level. Descriptive analyses of participant details, interventions, and outcomes were conducted and where appropriate data were available, a meta-analysis was performed and presented as a risk ratio (RR) or mean difference (MD) with 95% confidence intervals (CIs). The risk of bias was assessed using the Cochrane risk of bias tool and the quality of evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach., Results: Nine RCTs with 536 participants were included. In comparison with lipid-lowering drugs alone, HHT as an adjunctive therapy to lipid-lowering drugs or as a monotherapy showed significantly superior (MD -1.15 mmol/L, 95% CI -1.25 to -1.05) or inferior results (MD 0.23 mmol/L, 95% CI 0.09 to 0.38), respectively, for LDL-C levels. The incidence of adverse events was significantly lower when HHT was used in addition to lipid-lowering drugs, in comparison to that with lipid-lowering drugs alone. No serious adverse events were reported in the HHT group. Most included studies showed a high risk of performance bias and the quality of evidence was rated generally "low" because of the high risk of bias and inconsistency or imprecision of the meta-analysis results., Conclusion: Current evidence suggests that HHT may be beneficial for patients with dyslipidemia and may reduce the adverse events associated with lipid-lowering drugs. However, due to the high risk of bias of the included studies and low quality of evidence for the main findings, no definitive conclusion could be reached. Further rigorous, high-quality, and placebo-controlled RCTs should be conducted to assess the efficacy of HHT., Trial Registration Number: PROSPERO CRD42020164563., Competing Interests: The authors have no conflicts of interest to declare., (Copyright © 2020 the Author(s).

Importance: Nonadherence to statin guidelines is common. The solute carrier organic anion transporter family member 1B1 (SLCO1B1) genotype is associated with simvastatin myopathy risk and is proposed for clinical implementation. The unintended harms of using pharmacogenetic information to guide pharmacotherapy remain a concern for some stakeholders., Objective: To determine the impact of delivering SLCO1B1 pharmacogenetic results to physicians on the effectiveness of atherosclerotic cardiovascular disease (ASCVD) prevention (measured by low-density lipoprotein cholesterol [LDL-C] levels) and concordance with prescribing guidelines for statin safety and effectiveness., Design, Setting, and Participants: This randomized clinical trial was performed from December 2015 to July 2019 at 8 primary care practices in the Veterans Affairs Boston Healthcare System. Participants included statin-naive patients with elevated ASCVD risk. Data analysis was performed from October 2019 to September 2020., Interventions: SLCO1B1 genotyping and results reporting to primary care physicians at baseline (intervention group) vs after 1 year (control group)., Main Outcomes and Measures: The primary outcome was the 1-year change in LDL-C level. The secondary outcomes were 1-year concordance with American College of Cardiology-American Heart Association and Clinical Pharmacogenetics Implementation Consortium (CPIC) guidelines for statin therapy and statin-associated muscle symptoms (SAMS)., Results: Among 408 patients (mean [SD] age, 64.1 [7.8] years; 25 women [6.1%]), 193 were randomized to the intervention group and 215 were randomized to the control group. Overall, 120 participants (29%) had a SLCO1B1 genotype indicating increased simvastatin myopathy risk. Physicians offered statin therapy to 65 participants (33.7%) in the intervention group and 69 participants (32.1%) in the control group. Compared with patients whose physicians did not know their SLCO1B1 results at baseline, patients whose physicians received the results had noninferior reductions in LDL-C at 12 months (mean [SE] change in LDL-C, -1.1 [1.2] mg/dL in the intervention group and -2.2 [1.3] mg/dL in the control group; difference, -1.1 mg/dL; 90% CI, -4.1 to 1.8 mg/dL; P < .001 for noninferiority margin of 10 mg/dL). The proportion of patients with American College of Cardiology-American Heart Association guideline-concordant statin prescriptions in the intervention group was noninferior to that in the control group (12 patients [6.2%] vs 14 patients [6.5%]; difference, -0.003; 90% CI, -0.038 to 0.032; P < .001 for noninferiority margin of 15%). All patients in both groups were concordant with CPIC guidelines for safe statin prescribing. Physicians documented 2 and 3 cases of SAMS in the intervention and control groups, respectively, none of which was associated with a CPIC guideline-discordant prescription. Among patients with a decreased or poor SLCO1B1 transporter function genotype, simvastatin was prescribed to 1 patient in the control group but none in the intervention group., Conclusions and Relevance: Clinical testing and reporting of SLCO1B1 results for statin myopathy risk did not result in poorer ASCVD prevention in a routine primary care setting and may have been associated with physicians avoiding simvastatin prescriptions for patients at genetic risk for SAMS. Such an absence of harm should reassure stakeholders contemplating the clinical use of available pharmacogenetic results., Trial Registration: ClinicalTrials.gov Identifier: NCT02871934.

We herein report a rare case presenting with severe hypercholesterolemia, massive Achilles tendon xanthomas, and multi-vessel coronary artery disease. Initially, the patient was misdiagnosed with familial hypercholesterolemia. However, a genetic analysis using our custom sequencing panel covering genes associated with Mendelian lipid disorders revealed him to have a genetic basis of sitosterolemia with compound heterozygous mutations in the adenosine triphosphate binding cassette subfamily G5 (ABCG5) gene. A comprehensive genetic analysis can be particularly useful for diagnosing cases with severe phenotypes, leading to appropriate and medical therapies. Our patient was refractory to statins, whereas ezetimibe and PCSK9 inhibitor with a low-plant-sterol diet successfully reduced his serum levels of low-density lipoprotein cholesterol.

Background: The clinical benefit of LDL cholesterol lowering treatment in older patients remains debated. We aimed to summarise the evidence of LDL cholesterol lowering therapies in older patients., Methods: In this systematic review and meta-analysis, we searched MEDLINE and Embase for articles published between March 1, 2015, and Aug 14, 2020, without any language restrictions. We included randomised controlled trials of cardiovascular outcomes of an LDL cholesterol-lowering drug recommended by the 2018 American College of Cardiology and American Heart Association guidelines, with a median follow-up of at least 2 years and data on older patients (aged ≥75 years). We excluded trials that exclusively enrolled participants with heart failure or on dialysis because guidelines do not recommend lipid-lowering therapy in such patients who do not have another indication. We extracted data for older patients using a standardised data form for aggregated study-level data. We meta-analysed the risk ratio (RR) for major vascular events (a composite of cardiovascular death, myocardial infarction or other acute coronary syndrome, stroke, or coronary revascularisation) per 1 mmol/L reduction in LDL cholesterol., Findings: Data from six articles were included in the systematic review and meta-analysis, which included 24 trials from the Cholesterol Treatment Trialists' Collaboration meta-analysis plus five individual trials. Among 244 090 patients from 29 trials, 21 492 (8·8%) were aged at least 75 years, of whom 11 750 (54·7%) were from statin trials, 6209 (28·9%) from ezetimibe trials, and 3533 (16·4%) from PCSK9 inhibitor trials. Median follow-up ranged from 2·2 years to 6·0 years. LDL cholesterol lowering significantly reduced the risk of major vascular events (n=3519) in older patients by 26% per 1 mmol/L reduction in LDL cholesterol (RR 0·74 [95% CI 0·61-0·89]; p=0·0019), with no statistically significant difference with the risk reduction in patients younger than 75 years (0·85 [0·78-0·92]; p interaction =0·37). Among older patients, RRs were not statistically different for statin (0·82 [0·73-0·91]) and non-statin treatment (0·67 [0·47-0·95]; p interaction =0·64). The benefit of LDL cholesterol lowering in older patients was observed for each component of the composite, including cardiovascular death (0·85 [0·74-0·98]), myocardial infarction (0·80 [0·71-0·90]), stroke (0·73 [0·61-0·87]), and coronary revascularisation (0·80 [0·66-0·96])., Interpretation: In patients aged 75 years and older, lipid lowering was as effective in reducing cardiovascular events as it was in patients younger than 75 years. These results should strengthen guideline recommendations for the use of lipid-lowering therapies, including non-statin treatment, in older patients., Funding: None., (Copyright © 2020 Elsevier Ltd.

Objective: To carry out a systematic review on the effects of phytosterol supplementation on the treatment of dyslipidemia in children and adolescents., Data Sources: Review in the SciELO, Lilacs, Bireme, PubMed and Web of Science databases, with no time limit. Descriptors: phytosterols or plant sterols and dyslipidemias, hypercholesterolemia, cholesterol, children, adolescent, in English and Portuguese. The articles included were published in Portuguese, English or Spanish and evaluated the effect of phytosterol supplementation in pediatric patients with dyslipidemia. Documents that involved adults or animals, review papers, case studies and abstracts were excluded. Two authors performed independent extraction of articles. Of 113 abstracts, 19 were read in full and 12 were used in this manuscript., Data Synthesis: Phytosterol supplementation to reduce cholesterol levels has been shown to be effective in reducing LDL-cholesterol levels by approximately 10%, with reductions above 10% in LDL-cholesterol levels observed after 8 to 12 weeks of intervention. Studies have not shown significant changes in HDL-cholesterol and triglyceride levels. Based on the absence of adverse effects, its use seems to be safe and of good tolerance in children and adolescents., Conclusions: Phytosterol supplementation seems to be of great therapeutic aid for the treatment of hypercholesterolemia in children and adolescents. Further studies assessing the long-term effect of phytosterol supplementation are necessary.

Importance: Effective strategies for preventing type 2 diabetes are needed. Many people turn to complementary medicines, but there is little well-conducted scientific evidence to support their use., Objective: To assess the efficacy of α-cyclodextrin for cholesterol control and that of hydrolyzed ginseng for glycemic control in people with prediabetes and overweight or obesity., Design, Setting, and Participants: This 6-month double-blind, placebo-controlled, randomized clinical trial, with a 2 × 2 factorial design, was conducted between July 2015 and October 2018 at 2 locations in Sydney, Australia. Eligible participants were aged 18 years or older, had a body mass index (weight in kilograms divided by height in meters squared) of 25 or higher, and had prediabetes within 6 months of study entry according to the American Diabetes Association guidelines. Data analysis was performed from May to August 2019., Interventions: Participants were randomized to 1 of 4 groups to take active or placebo versions of each supplement (α-cyclodextrin plus hydrolyzed ginseng, α-cyclodextrin plus placebo, placebo plus hydrolyzed ginseng, or placebo plus placebo) for 6 months. All participants received dietetic advice for weight loss., Main Outcomes and Measures: The primary outcomes were the differences in total cholesterol and fasting plasma glucose between groups after 6 months. The primary analysis used the intention-to-treat principle. Multiple predetermined subsample analyses were conducted., Results: A total of 401 participants were eligible for the study (248 women [62%]; mean [SD] age, 53.5 [10.2] years; mean [SD] body mass index, 34.6 [6.2]). One hundred one patients were randomized to receive α-cyclodextrin plus hydrolyzed ginseng, 99 were randomized to receive α-cyclodextrin plus placebo, 101 were randomized to receive placebo plus hydrolyzed ginseng, and 100 were randomized to receive placebo plus placebo. For 200 participants taking α-cyclodextrin compared with 201 participants taking placebo, there was no difference in total cholesterol after 6 months (-1.5 mg/dL; 95% CI, -6.6 to 3.5 mg/dL; P = .51). For 202 participants taking hydrolyzed ginseng compared with 199 participants taking placebo, there was no difference in fasting plasma glucose after 6 months (0.0 mg/dL; 95% CI, -1.6 to 1.8 mg/dL; P = .95). Use of α-cyclodextrin was associated with constipation (16 participants vs 4 participants; P = .006) and cough (8 participants vs 1 participant; P = .02). Use of hydrolyzed ginseng was associated with rash and pruritus (13 participants vs 2 participants; P = .006). Only 37 of 401 participants (9.2%) experienced these adverse events., Conclusions and Relevance: Although they are safe for use, there was no benefit found for either α-cyclodextrin for cholesterol control or hydrolyzed ginseng for glycemic control in people with prediabetes and overweight or obesity., Trial Registration: Australian New Zealand Clinical Trials Registry Identifier: ACTRN12614001302640.

Nephrotic syndrome is sometimes refractory; however, it is rarely accompanied by acute pancreatitis. A 47-year-old Japanese woman complaining of limb edema was diagnosed with nephrotic syndrome. Blood and urine examinations suggested minimal change nephrotic syndrome (MCNS), and pulse intravenous methylprednisolone was administered, followed by oral prednisolone. Although proteinuria improved, the patient's condition remained unchanged, and diuresis was insufficient. As in patients with other nephrotic syndromes, this patient showed significant dyslipidemia. Atorvastatin was started for remarkable dyslipidemia since her admission, but her low-density lipoprotein cholesterol (LDL-C) level did not improve significantly. During the clinical course, she developed acute pancreatitis, and large-volume fluid replacement was performed. Although diuretic levels were increased in response to the increased fluid volume, diuresis was not enough, and lung edema developed. Extracorporeal ultrafiltration was started to ameliorate the lung edema. With the onset of pancreatitis, oral intake, including atorvastatin, was discontinued, and prednisolone was administered intravenously. To treat the high-LDL cholesterolemia, 140 mg of evolocumab was injected subcutaneously. Nausea slightly decreased on the following day, and the administration of 150 mg cyclosporine was initiated. LDL-C levels, proteinuria, and renal function promptly ameliorated. The results of a renal biopsy suggested MCNS. On the 44th day of hospitalization, she had complete remission. Evolocumab is potentially effective for severe nephrotic syndrome with uncontrollable dyslipidemia.

Introduction: Bempedoic acid is a new agent that reduces low-density lipoprotein cholesterol. Since inhibits cholesterol synthesis through a different mechanism than statins, the adverse effects related to it may also be different. Therefore, the objective of the present meta-analysis was to evaluate the effect of bempedoic acid on new onset or worsening diabetes., Methods: We performed a meta-analysis including randomized trials of bempedoic acid therapy, reporting new onset or worsening diabetes with a minimum of 4 weeks of follow-up. The fixed-effects model was performed. This meta-analysis was performed according to PRISMA guidelines., Results: Five eligible trials of bempedoic acid, including 3629 patients, were identified and considered eligible for the analyses. A total of 2419 subjects were allocated to receive bempedoic acid while 1210 subjects were allocated to the respective control arms. Bempedoic acid therapy is associated with a significant reduction in new onset or worsening diabetes [Odds Ratio: 0.66, 95% confidence interval: 0.48-0.90; I2: 0%]., Conclusion: This data suggests that the use of bempedoic acid significantly reduces the new onset or worsening diabetes risk. This finding should be confirmed with future studies., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier B.V.

Aims: Guidelines recommend targeting non-high-density lipoprotein cholesterol to reduce cardiovascular risk. We assessed the impact of baseline triglycerides on non-high-density lipoprotein cholesterol goal attainment in 10 phase 3 trials with alirocumab versus control ( n  = 4983)., Methods: Trials were grouped into four pools based on alirocumab dose (75-150 mg every 2 weeks), control (placebo/ezetimibe) and statin use. Baseline triglyceride quintiles were built within each pool. Non-high-density lipoprotein cholesterol goal attainment (very high risk: <100 mg/dl; moderate/high risk: <130 mg/dl), low-density lipoprotein cholesterol goal attainment (very high risk: <70 mg/dl; moderate/high risk: <100 mg/dl) and changes from baseline in lipid parameters were assessed at Week 24 among baseline triglyceride quintiles., Results: Higher baseline triglycerides were associated with a worse cardiovascular risk profile. Low-density lipoprotein cholesterol and non-high-density lipoprotein cholesterol increased with higher triglycerides, but the magnitude in non-high-density lipoprotein cholesterol was three- to four-fold higher compared with the increase in low-density lipoprotein cholesterol. Non-high-density lipoprotein cholesterol and low-density lipoprotein cholesterol percentage reductions from baseline with alirocumab were similar regardless of baseline triglycerides. A greater proportion of alirocumab-treated patients attained non-high-density lipoprotein cholesterol and low-density lipoprotein cholesterol goals compared with placebo or ezetimibe. Unlike low-density lipoprotein cholesterol goal attainment, non-high-density lipoprotein cholesterol goal attainment significantly declined with increasing baseline triglycerides ( p  < 0.05 for trend tests). A single standard deviation increase in baseline log(triglycerides) was significantly associated with lower odds ratios of attaining non-high-density lipoprotein cholesterol goals in the different pools and treatment (alirocumab/placebo/ezetimibe) groups, unlike low-density lipoprotein cholesterol goal attainment., Conclusion: Individuals with increased triglycerides have higher non-high-density lipoprotein cholesterol levels and lower rates of non-high-density lipoprotein cholesterol goal attainment (unlike low-density lipoprotein cholesterol goal attainment). Alirocumab improves non-high-density lipoprotein cholesterol goal attainment in this population. These results highlight the impact of triglycerides on non-high-density lipoprotein cholesterol and the need for novel therapies targeting triglyceride-related pathways.

Lipoprotein(a) (Lp(a)) was discovered more than 50 years ago, and a decade later, it was recognized as a risk factor for coronary artery disease. However, it has gained importance only in the past 10 years, with emergence of drugs that can effectively decrease its levels. Lp(a) is a low-density lipoprotein (LDL) with an added apolipoprotein(a) attached to the apolipoprotein B component via a disulphide bond. Circulating levels of Lp(a) are mainly genetically determined. Lp(a) has many functions, which include proatherosclerotic, prothrombotic and pro-inflammatory roles. Here, we review recent data on the role of Lp(a) in the atherosclerotic process, and treatment options for patients with cardiovascular diseases. Currently 'Proprotein convertase subtilisin/kexin type 9' (PCSK9) inhibitors that act through non-specific reduction of Lp(a) are the only drugs that have shown effectiveness in clinical trials, to provide reductions in cardiovascular morbidity and mortality. The effects of PCSK9 inhibitors are not purely through Lp(a) reduction, but also through LDL cholesterol reduction. Finally, we discuss new drugs on the horizon, and gene-based therapies that affect transcription and translation of apolipoprotein(a) mRNA. Clinical trials in patients with high Lp(a) and low LDL cholesterol might tell us whether Lp(a) lowering per se decreases cardiovascular morbidity and mortality.KEY MESSAGESLipoprotein(a) is an important risk factor in patients with cardiovascular diseases.Lipoprotein(a) has many functions, which include proatherosclerotic, prothrombotic and pro-inflammatory roles.Treatment options to lower lipoprotein(a) levels are currently scarce, but new drugs are on the horizon.

The American College of Cardiology/American Heart Association Task Force on Clinical Practice Guidelines recently published its 2018 recommendations on management of LDL cholesterol (LDL-C) in people with diabetes. For primary prevention, moderate-intensity statin therapy is recommended for those aged 40-75 years, with a preference for high-intensity statin treatment for older subjects and for those with higher estimated risk or risk-enhancing factors following a patient-clinician discussion. Statin therapy may be reasonable in adults <40 years or >75 years of age where there is less evidence for benefit. For people with diabetes and established atherosclerotic cardiovascular disease, high-intensity statin therapy is recommended. The majority of these subjects have very high risk, and an LDL-C goal of <70 mg/dL is recommended. If this target is not achieved, ezetimibe and/or a proprotein convertase subtilisin/kexin type 9 inhibitor may be added., (© 2020 by the American Diabetes Association.)
