Objective: Hyperlipidemia plays a crucial role in increasing the risk of cardiovascular diseases such as atherosclerosis. Recent studies have established that inclisiran positively influences lipid regulation. Nevertheless, its effectiveness in comparison to conventional treatments is still questionable. Hence, a methodical assessment of its effectiveness and safety is required. This research evaluates the efficacy and safety of inclisiran, PCSK9 inhibitors, and the combination of statins with ezetimibe in the treatment of hyperlipidemia via a network meta-analysis of randomized controlled trials (RCTs). Methods: We performed an extensive search of English-language publications in the PubMed, Medline, Embase, and Cochrane Library databases until April 2024. We conducted a web-based meta-analysis and reported in accordance with the guidelines. We selected the percentage change in low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), triglycerides (TG), and high-density lipoprotein cholesterol (HDL-C) as efficacy evaluation metrics and the incidence of adverse events as safety evaluation metrics for analysis and comparison. Result: We incorporated 33 studies involving 23,375 patients, evaluating three interventions regarding their effects on LDL-C, TC, TG, HDL-C, and adverse events. All treatments improved metrics over placebo. Inclisiran significantly reduced LDL-C compared to statins (mean − 15.21, 95% CI [-25.19, -5.23]) but showed no significant difference from statin + ezetimibe. Surface under the cumulative ranking curve (SUCRA) rankings placed inclisiran highest for LDL-C reduction (26.2%). The combination of statin and ezetimibe was the most efficacious for triglyceride reduction (mean 17.2, 95% CI [10.22, 24.19]; mean 15.61, 95% CI [16.87, 24.35]). The safety profiles were comparable across treatments. Conclusion: Inclisiran with its superior LDL-C reduction and low frequency of administration, appears promising for hyperlipidemia treatment, particularly for patients with adherence issues or side effects from other medications.

Aims Proprotein convertase anti-subtilisin–kexin type 9 inhibitors (PCSK9Is) improve plaque volume and composition and reduce major adverse coronary events in chronic coronary artery disease. We evaluated the effects of the short-term use of PCSK9Is on coronary plaque stability in patients with acute coronary syndrome (ACS) using optical coherence tomography (OCT). Methods and results This is a multicentre, open-label randomized controlled trial. The enrolled 80 subjects met the inclusion criteria. Of these, 52 patients (age 60 ± 11 years, 38 men, 14 women) with ST-elevated ACS had undergone successful primary percutaneous coronary intervention with LDL-cholesterol (LDL-C) levels > 70 mg/dL while receiving high-intensity statins. Participants were randomly assigned to the PCSK9I group (evolocumab 420 mg for 3 months, n = 29) or the standard of care (SoC) group (n = 23). Optical coherence tomography was performed at baseline (BL) and 3 and 9 months after randomization to assess lipid-rich plaques in non-culprit lesions. The change in the minimum fibrous cap thickness (MFCT) from BL to 9 months was the primary endpoint. The percentage change in LDL-C levels from BL to 3 months was significantly greater in the PCSK9I group (−67.8 ± 21.5% in the PCSK9I group vs. −16.3 ± 21.8% in the SoC group; P < 0.0001), and the difference between the two groups disappeared from BL to 9 months (−20.0 ± 37.8% in the PCSK9I group vs. −6.7 ± 34.2% in the SoC group; P = 0.20). The changes in MFCT from BL to 9 months were significantly greater in the PCSK9I group, even after PCSK9I discontinuation {100 μm [interquartile range (IQR): 45–180 μm] vs. 50 μm [IQR: 0–110 μm]; P = 0.032}. Conclusion Combination treatment with PCSK9Is and statins resulted in more marked plaque stabilization after ACS than SoC alone, and this effect persisted for 6 months after PCSK9I discontinuation.

Atherosclerotic cardiovascular disease (ASCVD) remains the leading cause of death worldwide and the risk of a major cardiovascular event is highest among those with established disease. Ongoing management of these patients relies on the accurate assessment of their response to any prescribed therapy, and their residual risk, in order to optimize treatment. Recent international guidelines and position statements concur that the plasma concentration of apolipoprotein B (apoB) is the most accurate measure of lipoprotein associated ASCVD risk. This is especially true for the growing number of individuals with diabetes, obesity, or the metabolic syndrome, and those on statin therapy. Most guidelines, however, continue to promote LDL-C as the primary risk marker due to uncertainty as to whether the greater accuracy of apoB is sufficient to warrant a paradigm shift. Recommendations regarding apoB measurement vary, and the information provided on how to interpret apoB results is sometimes insufficient, particularly for non-lipid specialists. Misinformation regarding the reliability of the assays is also frequently repeated despite its equivalent or better standardization than many other diagnostic assays. Thus, demand for apoB testing is relatively low, which means there is little incentive to increase its availability or reduce its cost. In this review, we examine the results of recent clinical outcomes studies and meta-analyses on the relative values of apoB, LDL-C, and non-HDL-C as markers of ASCVD risk. Although there is seemingly minimal difference among these markers when only population-based metrics are considered, it is evident from our analysis that, from a personalized or precision medicine standpoint, many individuals would benefit, at a negligible total cost, if apoB measurement were better integrated into the diagnosis and treatment of ASCVD.

Background: A statin alone or non-statins as add-ons have been introduced to intensive low-density lipoprotein cholesterol (LDL-C) -lowering therapy in patients at risk for high cardiovascular disease (CVD). The purpose of this study was to evaluate the effectiveness and safety of different rosuvastatin-based regimens for patients at high risk. Methods: Three hundred patients at high CVD risk were randomly assigned to the statin group (rosuvastatin, 20 mg/d), statin_EZ group (statin 10 mg/d + ezetimibe 10 mg/d), statin_pcsk group (statin 10 mg/d + alirocumab 75 mg/2 weeks) or combine3 group (statin 10 mg/d + ezetimibe 10 mg/d + alirocumab 75 mg/2 weeks). The primary outcome measure was cholesterol levels after 24 weeks of follow-up. Secondary outcomes included safety markers and the proportion of patients achieving the 70 mg/dL (1.8 mmol/L) target for LDL-C. A logistic regression model was performed to explore the factors affecting lipid target achievement. Results: The total cholesterol (TC) and LDL-C levels in the four groups after treatment were significantly lower than those before treatment. TC and LDL-C levels after treatment were significantly different among the four groups (p < 0.05). The levels in both the combine3 and statin_pcsk9 groups were significantly lower than those in the statin and statin_EZ groups (p < 0.05), but there was no significant difference between the combine3 and statin_pcsk9 groups. Fifty-one participants (69%) in the statin_pcsk9 group and 56 participants (78%) in the combine3 group achieved the target. Body mass index (BMI) and hypertensive status were related to LDL-C target achievement. The incidence of adverse events in the four groups was low. Conclusions: The combination of a statin and a PCSK9 inhibitor was safe and more effective for the treatment of high-risk CVD patients, while the addition of ezetimibe was unable to significantly lower lipid levels any further. The rate of achieving the target was higher in patients with hypertension and a low BMI. [ABSTRACT FROM AUTHOR]

Background: Guidelines advocate for intensive lipid‐lowering in patients with atherosclerotic cardiovascular disease (ASCVD). In May 2020, evolocumab, a proprotein convertase subtilisin‐kexin type 9 (PCSK9) inhibitor, became government subsidised in Australia for patients with ASCVD requiring further low‐density lipoprotein cholesterol (LDL‐C) lowering. Aim: To identify barriers to prescribing PCSK9 inhibitors in hospitalised patients with ASCVD. Methods: A retrospective 3‐month, single‐site, observational analysis was conducted in consecutive patients undergoing percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) surgery. Lipid‐lowering therapy prescriptions, including PSCK9 inhibitors, were assessed using electronic medical records, compared against the Australian Pharmaceutical Benefits eligibility criteria, and barriers to PCSK9 inhibitor use identified. Results: Of 331 patients, 244 (73.7%) underwent PCI and 87 (26.3%) underwent CABG surgery. A lipid profile during or within 8 weeks of admission was measured for 202 (82.8%) patients undergoing PCI and 59 (67.8%) undergoing CABG surgery. In patients taking high‐intensity statins on admission (n = 109), LDL‐C ≥1.4, ≥1.8 and >2.6mmol/L was seen in 64 (58.7%), 44 (40.4%) and 19 (17.4%) patients respectively. High‐intensity statin prescribing at discharge was high (>80%); however, ezetimibe was initiated in zero patients with LDL‐C ≥1.4 mmol/L. There was variable advice given by clinicians for LDL‐C targets. No patients met the criteria for subsidised PSCK9 inhibitor therapy, largely due to lack of qualifying lipid levels following combined statin and ezetimibe therapy. Conclusion: Prescribing of non‐statin LDL‐C‐lowering therapies remains low in patients with ASCVD. Underprescribing of ezetimibe and suboptimal lipid testing rates are barriers to accessing subsidised PCSK9i therapy using current Australian eligibility criteria. [ABSTRACT FROM AUTHOR]

• Lipid-lowering therapy with statins or PCSK9i is associated with IPN regression. • Longer duration of statin therapy is associated with reduced carotid IPN. • No association between change in IPN and change in serum lipids/inflammatory markers. • Therapeutic IPN effects may represent a pathway distinct from serum lipid depletion. Intraplaque neovascularization (IPN), a key feature of vulnerable carotid plaque, is associated with adverse cardiovascular (CV) events. Statin therapy has been shown to diminish and stabilize atherosclerotic plaque, but its effect on IPN is uncertain. This review investigated the effects of common pharmacologic anti-atherosclerotic therapies on carotid IPN. Electronic databases (MEDLINE, EMBASE and Cochrane Library) were searched from inception until July 13, 2022. Studies evaluating the effect of anti-atherosclerotic therapy on carotid IPN among adults with carotid atherosclerosis were included. Sixteen studies were eligible for inclusion. Contrast-enhanced ultrasound (CEUS) was the most common IPN assessment modality (n=8), followed by dynamic contrast-enhanced MRI (DCE-MRI) (n=4), excised plaque histology (n=3) and superb microvascular imaging (n=2). In fifteen studies, statins were the therapy of interest and one study assessed PCSK9 inhibitors. Among CEUS studies, baseline statin use was associated with a lower frequency of carotid IPN (median OR = 0.45). Prospective studies showed regression of IPN after 6-12 months of lipid-lowering therapy, with more regression observed in treated participants compared to untreated controls. Our findings suggest that lipid-lowering therapy with statins or PCSK9 inhibitors is associated with IPN regression. However, there was no correlation between change in IPN parameters and change in serum lipids and inflammatory markers in statin-treated participants, so it is unclear whether these factors are mediators in the observed IPN changes. Lastly, this review was limited by study heterogeneity and small sample sizes, so larger trials are needed to validate findings. [Display omitted] [ABSTRACT FROM AUTHOR]

Aims Long-term, placebo-controlled cholesterol-lowering trials have demonstrated legacy effects (clinical benefits that persist or emerge after trial end). It is unknown whether legacy effects follow a short period of very low low-density lipoprotein cholesterol (LDL-C) levels achieved with statin plus proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor. Methods and results In 18 924 patients with recent acute coronary syndrome, the ODYSSEY OUTCOMES trial compared the PCSK9 inhibitor alirocumab with placebo, each added to high-intensity or maximum-tolerated statin therapy. Patients with two consecutive LDL-C levels <0.39 mmol/L (15 mg/dL) on alirocumab had blinded placebo substitution for the remainder of the trial with continued statin treatment. In post hoc analyses, major adverse cardiovascular events (MACE) in these patients were compared to MACE in propensity score–matched patients from the placebo group with similar baseline characteristics and study medication adherence. In the alirocumab group, 730 patients had blinded placebo substitution at a median of 8.3 months from randomization, after a median of 6.0 months with LDL-C <0.39 mmol/L. They were matched to 1460 placebo patients. Both groups had lower baseline LDL-C and lipoprotein(a) and better study medication adherence than those of the overall cohort. Over a median follow-up of 2.8 years, MACE occurred in 47 (6.4%) alirocumab patients with limited-duration, very low achieved LDL-C vs. 122 (8.4%) matched placebo patients (treatment hazard ratio 0.72; 95% confidence interval 0.51, 0.997; P = 0.047). Conclusion A short period of LDL-C levels <0.39 mmol/L achieved with statin and alirocumab, followed by statin monotherapy, was associated with a lower risk of MACE than statin monotherapy throughout the observation period. Clinical benefit persisted for several years. Trial registration ClinicalTrials.gov NCT01663402 [ABSTRACT FROM AUTHOR]

Dyslipidemia is a major risk factor for stroke, following hypertension, diabetes, and smoking, and is an important risk factor for the prevention and treatment of coronary artery disease and peripheral vascular disease, including stroke. Recent guidelines recommend considering low-density lipoprotein cholesterol (LDL-C)-lowering therapies, such as statins (preferably), ezetimibe, or proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors to prevent the occurrence or recurrence of stroke, adhering to the "lower is better" approach. In this review, we examined the evidence supporting lipid-lowering medications like statins, ezetimibe, and PCSK9 inhibitors for secondary stroke prevention and dyslipidemia management in different stroke subtypes. Stroke guidelines advocate for administering the maximum tolerable dose of statins as the primary treatment and as soon as possible despite the potential for new-onset diabetes mellitus and possible muscle and liver toxicity due to their demonstrated benefits in secondary prevention of cardiovascular diseases and mortality reduction. When statin use is insufficient for LDL lowering, ezetimibe and PCSK9 inhibitors are recommended as complementary therapies. It is essential to establish lipid-lowering therapy goals based on the stroke subtype and the presence of comorbidities. [ABSTRACT FROM AUTHOR]

Introduction: Intracranial atherosclerotic stenosis (ICAS) is a common cause of stroke worldwide. Evolocumab, a proprotein convertase subtilisin/kexin type-9 inhibitor (PCSK9i), effectively lowers low-density lipoprotein (LDL) and produces favorable changes in coronary atherosclerosis. This study aimed to determine the effects of PCSK9i on intracranial plaques in moderate-intensity statin-treated individuals with ICAS. Methods: This prospective, observational study monitored the imaging and clinical outcomes of individuals with ICAS who were consecutively treated with moderate-intensity statins with or without PCSK9i. Individuals underwent monthly visits and repeat high-resolution MRI (HR-MRI) at week 12. The primary outcome was a change in HR-MRI after 12 weeks of treatment and the secondary outcome was major vascular events during follow-up. Results: Forty-nine individuals were studied (PCSK9i group: 26 individuals with 28 abnormal vascular regions; statin group: 23 with 27 regions). The PCSK9i group showed a significant reduction in the normalized wall index (0.83 vs. 0.86, p = 0.028) and stenosis degree (65.5 vs. 74.2%, p = 0.01). Similarly, a greater percentage of individuals with a good response to the efficacy of treatment were treated in the PCSK9i group than that in the statin group (75 vs. 44.4%, p = 0.021). The incidence of major vascular events was overall similar between the groups. The treatment options (OR = 8.441, p = 0.01) and prior diabetes (OR = 0.061, p = 0.001) were significantly associated with the efficacy of treatment. Discussion: Statin and PCSK9i combination treatment stabilized intracranial atherosclerotic plaques more often compared to statins alone, as documented by HR-MRI. Further study is warranted to determine if combination treatment improves clinical outcomes in ICAS. [ABSTRACT FROM AUTHOR]

In fact, because the long COVID symptoms are frequent among COVID-19 patients (about 30% or more) who have been hospitalized, the American Heart Foundation has initiated an extensive program in order to determine if those individuals who have ASCVD or have survived stroke are more prone to develop long COVID (https://newsroom.heart.org/news/10-million-invested-to-study-long-term-impact-of-covid-19-on-heart-and-brain-health). Long COVID or Post-COVID Syndrome Long COVID or the post-COVID-19 syndrome has been defined as a condition characterized by persistent symptoms lasting more than 2 months after the onset of SARS-CoV-2 infection ([20]).

Summary: Background: Cardiovascular disease (CVD) is the most frequent cause of death in Austria. The European Society of Cardiology (ESC)/European Atherosclerosis Society (EAS) guidelines recommend intensive lipid lowering therapy (LLT) in patients at high or very high CV risk. Lipid management and achievement of low-density lipoprotein cholesterol (LDL-C) goals in Austria have not recently been assessed. Methods: Subgroup analysis for Austria of a European 18 country, cross-sectional, observational study. Patients received LLT for primary (PP) or secondary prevention (SP). Data including LLT in the preceding 12 months and most recent LDL‑C were collected during a single visit between June 2017 and November 2018. Achievement of the risk-based 2016 and 2019 ESC/EAS LDL‑C goal while receiving stabilized LLT was assessed. Results: A total of 293 patients were enrolled from 8 Austrian sites, of which 200 (PP = 104, SP = 96) received stabilized LLT at the LDL‑C measurement date. Overall, 58% (71% PP, 43% SP) and 38% (52% PP, 23% SP) achieved the risk-based 2016 and 2019 goals, respectively. Most patients received moderate-intensity statin monotherapy (46%), while 34% used high-intensity statin monotherapy. Combination therapy of moderate/high-intensity statin with ezetimibe (12%), or proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors with statin ± ezetimibe (1%), was used infrequently. Conclusion: The current Austrian routine lipid management using mainly moderate-intensity or high-intensity statin monotherapy is insufficient to attain ESC/EAS guideline goals, in particular the more stringent 2019 recommendations, a situation comparable to other participating European countries. In addition to switching to and optimizing doses of high-intensity statins, a combination with ezetimibe or PCSK9 inhibitors will be needed in many cases. [ABSTRACT FROM AUTHOR]

A recent meta-analysis of over 20,000 individuals showed that hospitalized COVID-19 patients with acute myocardial injury had more than fourfold higher mortality than those without such injury. Since the COVID-19 pandemic exacerbates already existing health inequalities, there is an urgent need to create measures to protect the most vulnerable patient groups, including those with a pre-existing increased risk of atherosclerotic cardiovascular disease (ASCVD). A typical example is familial hypercholesterolemia (FH), a common genetic disease affecting over 30 million individuals worldwide. If left untreated or undertreated, FH patients suffer from complications of premature ASCVD, such as acute coronary syndromes, resulting in acute myocardial injury/infarction. A recent population-based analysis provided strong evidence suggesting that COVID-19 poses an even higher risk for myocardial injury in FH patients. From the long-term preventive point of view, it is important to note that, in addition to the acutely elevated risk of myocardial injury, an elevated risk of ASCVD and its complications will persist after COVID-19. The decline in outpatient preventive care during the pandemic is likely to influence ASCVD risk and outcomes, particularly in high-risk patients, such as those with FH. This commentary aims to raise global awareness of the challenges that clinicians treating FH patients continue to face during the COVID-19 pandemic, with two low- to middle-income countries, South Africa and Brazil, serving as examples.

Cardiovascular disease (CVD) is the leading cause of death in the United States and worldwide. A major risk factor for this condition is increased serum low-density lipoprotein cholesterol (LDL-C) levels for which statins have been successful in reducing serum LDL-C to healthy concentrations. However, patients who are statin intolerant or those who do not achieve their treatment goals while on high-intensity statin therapy, such as those with familial hypercholesterolemia, remain at risk. With the discovery of PCSK9 inhibitors, the ability to provide more aggressive treatment for patients with homozygous and heterozygous familial hypercholesterolemia has increased. Ezetimibe reduces LDL-C by 15%-20% when combined with statin. 2 , 3 Protein convertase subtilisin/kexin type 9 (PCSK9) inhibitors have been found to achieve profound reductions in LDL-C (54%-74%) when added to statins. They have shown dramatic effects at lowering major adverse cardiovascular events (MACE) in high-risk patients 4 with LDL-C levels ≥70 mg/dL and can be used in populations that are statin intolerant or not at goal levels with maximally tolerated statin therapy. PCSK9 inhibitors also produce minimal side effects. Myopathy, a common side effect for patients on statins, has been rare in patients on PCSK9 inhibitors. Randomized trials have shown that reduction in LDL-C has translated to clinical benefits even in patients who have not achieved their LDL-C target. [ABSTRACT FROM AUTHOR]

Purpose of Review: The purpose of this article is to review current evidence for lipoprotein (a) (Lp(a)) as a risk factor for multiple cardiovascular (CV) disease phenotypes, provide a rationale for Lp(a) lowering to reduce CV risk, identify therapies that lower Lp(a) levels that are available clinically and under investigation, and discuss future directions. Recent Findings: Mendelian randomization and epidemiological studies have shown that elevated Lp(a) is an independent and causal risk factor for atherosclerosis and major CV events. Lp(a) is also associated with non-atherosclerotic endpoints such as venous thromboembolism and calcific aortic valve disease. It contributes to residual CV risk in patients receiving standard-of-care LDL-lowering therapy. Plasma Lp(a) levels present a skewed distribution towards higher values and vary widely between individuals and according to ethnic background due to genetic variants in the LPA gene, but remain relatively constant throughout a person’s life. Thus, elevated Lp(a) (≥50 mg/dL) is a prevalent condition affecting >20% of the population but is still underdiagnosed. Treatment guidelines have begun to advocate measurement of Lp(a) to identify patients with very high levels that have a family history of premature CVD or elevated Lp(a). Lipoprotein apheresis (LA) efficiently lowers Lp(a) and was recently associated with a reduction of incident CV events. Statins have neutral or detrimental effects on Lp(a), while PCSK9 inhibitors significantly reduce its level by up to 30%. Specific lowering of Lp(a) with antisense oligonucleotides (ASO) shows good safety and strong efficacy with up to 90% reductions. The ongoing CV outcomes study Lp(a)HORIZON will provide a first answer as to whether selective Lp(a) lowering with ASO reduces the risk of major CV events. Summary: Given the recently established association between Lp(a) level and CV risk, guidelines now recommend Lp(a) measurement in specific clinical conditions. Accordingly, Lp(a) is a current target for drug development to reduce CV risk in patients with elevated levels, and lowering Lp(a) with ASO represents a promising avenue. [ABSTRACT FROM AUTHOR]

Background With the availability of new lipid‐lowering therapy options, there is a need to compare the expected clinical benefit of different treatment strategies in different patient populations and over various time frames. We aimed to develop a time‐dependent model from published randomized controlled trials summarizing the relationship between low‐density lipoprotein cholesterol lowering and cardiovascular risk reduction and to apply the model to investigate the effect of treatment scenarios over time. Methods and Results A cardiovascular treatment benefit model was specified with parameters as time since treatment initiation, magnitude of low‐density lipoprotein cholesterol reduction, and additional patient characteristics. The model was estimated from randomized controlled trial data from 22 trials for statins and nonstatins. In 15 trials, the new time‐dependent model had better predictions than cholesterol treatment trialists’ estimations for a composite of coronary heart disease death, nonfatal myocardial infarction, and ischemic stroke. In explored scenarios, absolute risk reduction ≥2% with intensive treatment with high‐intensity statin, ezetimibe, and high‐dose proprotein convertase subtilisin/kexin type 9 inhibitor compared with high‐ or moderate‐intensity statin alone were achieved in higher‐risk populations with 2 to 5 years of treatment, and lower‐risk populations with 9 to 11 years of treatment. Conclusions The time‐dependent model accurately predicted treatment benefit seen from randomized controlled trials with a given lipid‐lowering therapy by incorporating patient profile, timing, duration, and treatment type. The model can facilitate decision making and scenario analyses with a given lipid‐lowering therapy strategy in various patient populations and time frames by providing an improved assessment of treatment benefit over time.

Background: The EBBINGHAUS (Evaluating PCSK9 Binding Antibody Influence on Cognitive Health in High Cardiovascular Risk Subjects) trial demonstrated that evolocumab added to a background statin did not affect cognitive performance in a subset of 1,204 patients enrolled in FOURIER (Further Cardiovascular Outcomes Research With PCSK9 inhibitors in Subjects With Elevated Risk).Objectives: The authors describe patient-reported cognition in the entire FOURIER trial using a self-survey.Methods: FOURIER was a randomized, double-blind, placebo-controlled trial involving patients with atherosclerotic cardiovascular disease and low-density lipoprotein cholesterol (LDL-C) levels ≥70 mg/dl or non-high-density cholesterol ≥100 mg/dl despite statin therapy. At the final visit, patients completed a 23-item survey on memory and executive domains from the Everyday Cognition (ECog) scale. Patients compared their levels of everyday function at the end of the trial with their levels at the beginning and scored as 1 (no change or improvement), 2 (occasionally worse), 3 (consistently little worse), or 4 (consistently much worse). ECog scores were compared by the 2 randomized treatment arms and by achieved LDL-C at 4 weeks.Results: A total of 22,655 patients completed ECog after a median duration of 2.2 years. The proportions of patients reporting cognitive decline (ECog score ≥2) at the end of the study were similar for placebo versus evolocumab, both for total score 3.6% versus 3.7% (p = 0.62) and for subdomains (memory, 5.8% vs. 6.0%; total executive, 3.6% vs. 3.7%). The proportion of patients reporting a decline in total cognitive score was similar among the 2,338 patients who achieved very low LDL-C levels (<20 mg/dl) compared to the 3,613 patients with LDL-C ≥100 mg/dl (3.8% vs. 4.5%, p = 0.57).Conclusions: The addition of evolocumab to maximally tolerated statin therapy had no impact on patient-reported cognition after an average of 2.2 years of treatment, even among patients who achieved LDL-C <20 mg/dl.

Patients who have experienced an acute coronary syndrome (ACS) are at very high risk of recurrent atherosclerotic cardiovascular disease (CVD) events. Dyslipidaemia, a major risk factor for CVD, is poorly controlled post ACS in countries outside Western Europe and North America, despite the availability of effective lipid-modifying therapies (LMTs) and guidelines governing their use. Recent guideline updates recommend that low-density lipoprotein cholesterol (LDL-C), the primary target for dyslipidaemia therapy, be reduced by ≥ 50% and to < 1.4 mmol/L (55 mg/dL) in patients at very high risk of CVD, including those with ACS. The high prevalence of CVD risk factors in some regions outside Western Europe and North America confers a higher risk of CVD on patients in these countries. ACS onset is often earlier in these patients, and they may be more challenging to treat. Other barriers to effective dyslipidaemia control include low awareness of the value of intensive lipid lowering in patients with ACS, physician non-adherence to guideline recommendations, and lack of efficacy of currently used LMTs. Lack of appropriate pathways to guide follow-up of patients with ACS post discharge and poor access to intensive medications are important factors limiting dyslipidaemia therapy in many countries. Opportunities exist to improve attainment of LDL-C targets by the use of country-specific treatment algorithms to promote adherence to guideline recommendations, medical education and greater prioritisation by healthcare systems of dyslipidaemia management in very high risk patients.

Introduction: Gender disparities in access to healthcare have been documented, including disparities in access to care for cardiovascular diseases (CVDs). Disparities in access to cardiologists could disadvantage some patients to the newer lipid-lowering proprotein convertase subtilisin/kexin type 9 inhibitor (PCSK9i) antibodies, as utilization management criteria for PCSK9is often require step therapy with statins and/or ezetimibe and prescription by a cardiologist. To assess whether these utilization management criteria disproportionally limit access to patients with certain characteristics, we assessed the use of cardiologist care and receipt of statin and/or ezetimibe prescriptions from a cardiologist by gender and other patient demographic and clinical characteristics.Methods: This cross-sectional study used administrative claims data from Inovalon's Medical Outcomes Research for Effectiveness and Economics Registry (MORE2 Registry®) for patients enrolled in commercial and Medicare Advantage healthcare plans from January 1, 2014, through December 31, 2014. Provider data from the registry were linked to individual demographic and administrative claims data. Logistic regression models were used to assess characteristics associated with outpatient visits to a cardiologist and receipt of a prescription for statin and/or ezetimibe from a cardiologist.Results: Data from 39,322 patients in commercial plans and 261,898 patients with Medicare Advantage were analyzed. Female gender (vs male) was associated with a significantly lower likelihood of visiting a cardiologist for patients in commercial plans (odds ratio [OR] 0.85; 95% confidence limit [CL] 0.81-0.88) and in Medicare Advantage plans (OR 0.82; 95% CL 0.81-0.83). Female gender was also associated with a lower likelihood of receiving a statin and/or ezetimibe prescription from a cardiologist for patients in commercial plans (OR 0.69; 95% CL 0.65-0.74) and in Medicare Advantage plans (OR 0.78; 95% CL 0.76-0.79).Conclusions: Compared with men, women were less likely to visit a cardiologist and less likely to receive a prescription for a statin and/or ezetimibe from a cardiologist.Funding: Amgen Inc.

Abstract Background Statins are generally well-tolerated and serious side effects are infrequent, but some patients experience adverse events and reduce their statin dose or discontinue treatment altogether. Alirocumab is a highly specific, fully human monoclonal antibody to proprotein convertase subtilisin/kexin type 9 (PCSK9), which can produce substantial and sustained reductions of low-density lipoprotein cholesterol (LDL-C). Methods The randomized, double-blind, placebo-controlled, parallel-group, phase 3 ODYSSEY NIPPON study will explore alirocumab 150 mg every 4 weeks (Q4W) in 163 Japanese patients with hypercholesterolemia who are on the lowest-strength dose of atorvastatin (5 mg/day) or are receiving a non-statin lipid-lowering therapy (LLT) (fenofibrate, bezafibrate, ezetimibe, or diet therapy alone). Hypercholesterolemia is defined as LDL-C ≥ 100 mg/dL (2.6 mmol/L) in patients with heterozygous familial hypercholesterolemia or non-familial hypercholesterolemia with a history of documented coronary heart disease, or ≥120 mg/dL (3.1 mmol/L) in patients with non-familial hypercholesterolemia classified as primary prevention category III (i.e. high-risk patients). During the 12-week double-blind treatment period, patients will be randomized (1:1:1) to receive alirocumab subcutaneously (SC) 150 mg Q4W alternating with placebo for alirocumab Q4W, or alirocumab 150 mg SC every 2 weeks (Q2W), or SC placebo Q2W. The primary efficacy endpoint is the percentage change in calculated LDL-C from baseline to week 12. The long-term safety and tolerability of alirocumab will also be investigated. Discussion The ODYSSEY NIPPON study will provide insights into the efficacy and safety of alirocumab 150 mg Q4W or 150 mg Q2W among Japanese patients with hypercholesterolemia who are on the lowest-strength dose of atorvastatin, or are receiving a non-statin LLT (including diet therapy alone). Trial registration ClinicalTrials.gov number: NCT02584504

Highlights • Alirocumab 150 mg Q4W dosing is efficacious in reducing low-density lipoprotein cholesterol. • Alirocumab 150 mg Q4W or Q2W is well tolerated in Japanese hypercholesterolemic patients. • Alirocumab 150 mg Q4W offers an alternative, flexible dosing, regimen for Japanese patients. Abstract Background Alirocumab, a fully human monoclonal antibody to proprotein convertase subtilisin/kexin type 9, given every 2 weeks (Q2W), significantly reduced low-density lipoprotein cholesterol (LDL-C) levels in Japanese hypercholesterolemic patients on background statin. We evaluated alirocumab 150 mg every 4 weeks (Q4W) in patients on lowest-dose statin or non-statin lipid-lowering therapy (LLT). Methods ODYSSEY NIPPON was a double-blind study conducted in Japanese patients with LDL-C ≥100 mg/dL (heterozygous familial hypercholesterolemia or non-familial hypercholesterolemia with coronary heart disease) or ≥120 mg/dL (non-familial hypercholesterolemia, Japan Atherosclerosis Society category III) on atorvastatin 5 mg/day or non-statin LLT. Patients were randomized (1:1:1) to subcutaneous alirocumab 150 mg Q4W, alirocumab 150 mg Q2W, or placebo for the 12-week double-blind treatment period (DBTP), followed by a 52-week open-label treatment period (OLTP). At entry into the OLTP, patients received alirocumab 150 mg Q4W, with possible up-titration to 150 mg Q2W at Week 24. Results Least-square mean percent change in LDL-C from baseline at Week 12 (primary efficacy endpoint) was −43.8% for alirocumab Q4W, −70.1% for Q2W, and −4.3% for placebo. During the OLTP, mean LDL-C change from baseline was −45.1% at Week 20, with a further reduction at Week 36, with achieved levels maintained to Week 64. Percent of patients with ≥1 adverse event (DBTP) was 51.9% with alirocumab Q4W, 47.2% with Q2W, and 46.4% with placebo. Most common adverse events were infections and infestations (25.9%, 22.6%, 17.9%, respectively), gastrointestinal disorders (13.0%, 9.4%, 12.5%), nervous system disorders (5.6%, 7.5%, 10.7%), and general disorders and administration-site conditions (3.7%, 11.3%, 5.4%). Conclusions Hypercholesterolemic Japanese patients who tolerate only lowest-strength dose statin or non-statin LLT can achieve robust LDL-C reduction with alirocumab 150 mg Q4W, in addition to their current LLT. Alirocumab 150 mg Q4W dosing was efficacious and generally well tolerated without new safety concerns. (ClinicalTrials.gov number: NCT02584504) [ABSTRACT FROM AUTHOR]

Despite the introduction of statins for lowering LDL-C level, atherosclerotic cardiovascular disease (ASCVD) remains a leading cause of death and morbidity worldwide. Combination therapies with statin and other lipid-lowering drugs, including ezetimibe and proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, have unlocked additive benefits for treatment of ASCVD, but morbidity and mortality due to ASCVD remain high. New anti-inflammatory therapies have emerged for treatment and prevention of ASCVD to address these problems. Canakinumab neutralization of interleukin-1β (IL-1β) is the only verified therapy, and low-dose methotrexate holds promise due to its efficacy and safety for treatment of ASCVD. However, many agonistic and antagonistic candidates within inflammation pathways have failed to develop into useful drugs for ASCVD because of the complexity of the inflammatory process in atherosclerosis. In this review, we outline current and future pharmaceutical therapies for ASCVD in terms of lipid-modifying strategies and anti-inflammation treatments. [ABSTRACT FROM AUTHOR]

In conclusion, the present systematic review and meta-analysis showed that in patients with previous cardiovascular events, the risk of stroke was significantly reduced in patients with and without previous stroke treated with PCSK9 inhibitors irrespective of the baseline LDL-C levels.

The beneficial effect of PCSK9 inhibitors in patients with previous cardiovascular events and stroke was not related to an increase of hemorrhagic stroke rates, irrespectively of the LDL-C levels.

• Real-world LDL-C target achievement rate is low in primary prevention FH patients. • Despite intensive statin use, only 33% were able to reach an LDL-C < 2.5 mmol/L. • Patients on high-intensity statins were two times more likely to achieve the LDL-C target. • We found no significant difference between men and women in target achievement rate. Statin and ezetimibe represent the first line of lipid-lowering therapy in patients with familial hypercholesterolemia (FH), a disease associated with a strong cardiovascular risk. The current low-density lipoprotein cholesterol (LDL-C) target achievement rate in a real-world context using these conventional treatments has never been investigated in the Province of Quebec (Canada). The primary objective of this study was to evaluate the proportion of FH patients in primary cardiovascular prevention who attained their recommended LDL-C threshold without being treated with a PCSK9 inhibitor. Patients included in this retrospective study were followed at the Lipid Clinic of the Montreal Clinical Research Institute. All patients were molecularly defined (97%) or had a definite clinical diagnosis of FH. A total of 225 patients were included in this study, of which 73% were on high-intensity statin therapy. While two-thirds of the cohort achieved the LDL-C treatment target of ≥ 50% reduction from baseline, only one third attained the target of < 2.5 mmol/L (<97 mg/dL). However, patients on high-intensity statin therapy were two times more likely to achieve the < 2.5 mmol/L targets as compared to those treated with low or moderate statin intensity (p = 0.01). There was no significant difference in treatment target achievement between men and women. Target achievement rate was unacceptably low in our FH patients. Conventional lipid-lowering treatments alone may not be sufficient in most FH patients to ensure adequate cardiovascular prevention. [ABSTRACT FROM AUTHOR]

Both HeFH and HoFH require dietary and lifestyle modification. Pharmacotherapy of adult HeFH patients is largely driven by the American Heart Association (AHA) algorithm. A high-potency statin is started initially with a goal low-density lipoprotein cholesterol (LDL-C) reduction of >50 %. The LDL-C target is adjusted to <100 or <70 mg/dL in subjects with coronary artery disease (CAD) with ezetimibe being second line. If necessary, a third adjunctive therapy, such as a PSCK9 inhibitor (not yet approved in children) or bile acid-binding resin, can be added. Finally, LDL-C apheresis can be considered in patients with LDL-C >300 mg/dL (or >200 mg/dL with significant CAD, although now approved for LDL-C as low as 160 mg/dL with CAD). Due to the early, severe LDL-C elevation in HoFH patients, concerning natural history, rarity of the condition, and nuances of treatment, all HoFH patients should be treated at a pediatric or adult center with HoFH experience. LDL-C apheresis should be considered as early as 5 years of age. However, apheresis availability and tolerability is limited and pharmacotherapy is required. Generally, the AHA algorithm with reference to the European Atherosclerosis Society Consensus Panel recommendations is reasonable with all patients initiated on high-dose, high-potency statin, ezetimibe, and bile acid-binding resins. In most, additional LDL-C lowering is required with PCSK9 inhibitors and/or lomitapide or mipomersen. Liver transplantation can also be considered at experienced centers as a last resort.

Familial hypercholesterolaemia (FH) is a common genetic cause of premature coronary heart disease (CHD). Globally, one baby is born with FH every minute. If diagnosed and treated early in childhood, individuals with FH can have normal life expectancy. This consensus paper aims to improve awareness of the need for early detection and management of FHchildren. Familial hypercholesterolaemia is diagnosed either on phenotypic criteria, i.e. an elevated low-density lipoprotein cholesterol(LDL-C) level plus a family history of elevated LDL-C, premature coronary artery disease and/or genetic diagnosis, or positive genetic testing. Childhood is the optimal period for discrimination between FH and non-FH using LDL-C screening. An LDL-C ≥5 mmol/L (190 mg/dL), or an LDL-C ≥4 mmol/L (160 mg/dL) with family history of premature CHD and/or high baseline cholesterol in one parent, make the phenotypic diagnosis. If a parent has a genetic defect, the LDL-C cut-off for the child is ≥3.5 mmol/L (130 mg/dL). We recommend cascade screening of families using a combined phenotypic and genotypic strategy. In children, testing is recommended from age 5 years, or earlier if homozygous FH is suspected. A healthy lifestyle and statin treatment (from age 8 to 10 years) are the cornerstones of management of heterozygous FH. Target LDL-C is <3.5 mmol/L (130 mg/dL) if >10 years, or ideally 50% reduction from baseline if 8-10 years, especially with very high LDL-C, elevated lipoprotein(a), a family history of premature CHD or other cardiovascular risk factors, balanced against the long-term risk of treatment side effects. Identifying FH early and optimally lowering LDL-C over the lifespan reduces cumulative LDL-C burden and offers health and socioeconomic benefits. To drive policy change for timely detection and management, we call for further studies in the young. Increased awareness, early identification, and optimal treatment from childhood are critical to adding decades of healthy life for children and adolescents with FH. [ABSTRACT FROM AUTHOR]
