The prevalence of HF with preserved ejection raction (HFpEF, with EF ≥50%) is increasing across all populations with high rates of hospitalization and mortality, reaching up to 80% and 50%, respectively, within a 5-year timeframe. Comorbidity-driven systemic inflammation is thought to cause coronary microvascular dysfunction and increased epicardial adipose tissue, leading to downstream friborsis and molecular changes in the cardiomyocyte, leading to increased stiffness and diastolic dynsfunction. HFpEF poses unique challenges in terms of diagnosis due to its complex and diverse nature. The diagnosis of HFpEF relies on a combination of clinical assessment, imaging studies, and biomarkers. An additional important step in diagnosing HFpEF involves excluding certain cardiac diagnoses that may be specific underlying causes of HFpEF or may be masquerading as HFpEF and require specific alternative treatment approaches. In addition to administering sodium-glucose cotransporter 2 inhibitors to all patients, the most effective approach to enhance clinical outcomes may involve tailored therapy based on each patient's unique clinical profile. Exercise should be recommended for all patients to improve the quality of life. Glucagon-like peptide-1 1 agonists are a promising treatment option in obese HFpEF patients. Novel approaches targeting inflammation are also in early phase trials., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier B.V. All rights reserved.)

Background: Transcatheter aortic valve replacement (TAVR) is the most common treatment in patients with symptomatic severe aortic stenosis (AS). As concomitant coronary artery disease is common in AS patients, access to the coronary arteries following TAVR is of increasing importance., Objectives: This study evaluated the incidence and risk factors for unplanned coronary angiography following TAVR and, using fluoroscopic time as a surrogate, analyzed the complexity of coronary artery cannulation., Methods: All patients who underwent TAVR in Sweden between 2008 and 2022 were identified using the SWEDEHEART registry. The cumulative incidence of coronary angiography after TAVR was analyzed with mortality as a competing risk. Angiography and PCI complexity were analyzed using fluoroscopic time and compared across different transcatheter heart valve designs., Results: Out of 9806 patients, 566 subsequently required coronary angiography. The incidence was highest for three-vessel and/or left main disease. Younger age, the extent of prior coronary artery disease, and peripheral vascular disease were associated with an increased risk of coronary angiography. Fluoroscopy time was increased in TAVR patients compared to the control group with the longest fluoroscopy times observed in cases involving supra-annular and self-expanding valves., Conclusions: The incidence of coronary angiography following TAVR is still low. Younger patients and patients with concomitant coronary artery disease have a higher risk. Procedural time is longer in patients with a previous THV replacement. As TAVR is emerging as the first-line treatment in patients with longer life expectancy, facilitating coronary access is an important factor when considering which THV device to implant., (© 2024 The Author(s).

The frequency and effectiveness of repeat mitral valve interventions (RMVI) after transcatheter edge-to-edge repair (TEER) for secondary mitral regurgitation (MR) are unknown. We aimed to examine the rate of and outcomes after RMVI after TEER in the Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation (COAPT) trial. Only 3.9% of COAPT trial patients required a repeat mitral valve intervention during 4-year follow-up which was successful in 90% of cases but was associated with an increased rate of heart failure (HF) hospitalizations (HFH). The COAPT trial randomized HF patients with severe secondary MR to TEER with the MitraClip device plus guideline-directed medical therapy (GDMT) versus GDMT alone. We evaluated the characteristics and outcomes of patients who had an RMVI during 4-year follow-up. A MitraClip implant was attempted in 293 patients randomized to TEER+GDMT, 10 of whom underwent an RMVI procedure (9 repeat TEER and 1 surgical mitral valve replacement) after 4 years of follow-up (cumulative incidence 3.90%, 95% confidence interval [CI] 2.08 to 7.08; median 182 days after the initial procedure). Patients with RMVI had larger mitral annular diameters, fewer clips implanted, and were more likely to have ≥3+MR at discharge compared with those without RMVI. Reasons for RMVI included failed index procedure because of difficult transseptal puncture (n = 2) or tamponade (n = 1); residual or recurrent severe MR after an initially successful procedure (n = 5); partial clip detachment (n = 1); and site-assessed mitral stenosis (n = 1). RMVI was successful in 8/10 (80%) patients. Patients who underwent RMVI had higher 4-year rates of HFH but similar mortality compared with those without RMVI. The annualized incidence rates of all HFH in patients who underwent RMVI were 234 events per 100 person-years (95% CI 139 to 395) pre-RMVI and 46 per 100 person-years (95% CI 25 to 86) post-RMVI as compared with 32 events per 100 patient-years (95% CI 28 to 36) in patients without RMVI. The rate ratio of HFH was reduced after RMVI in patients who underwent RMVI (0.20, 95% CI 0.09 to 0.45). In conclusion, the cumulative incidence of RMVI after 4 years was 3.9% in patients who underwent TEER for severe secondary MR in the COAPT trial. Patients who underwent RMVI were at increased risk of HFH which was reduced after the RMVI procedure.

Aim: To assess cause-specific death in patients with heart failure with preserved, mildly reduced, and reduced ejection fraction (HFpEF, HFmrEF, and HFrEF)., Methods and Results: Data were analysed from the Swedish Heart Failure Registry (SwedeHF) and the National Patient Register of patients enrolled in SwedeHF 2000-2021. Cox proportional hazards regression models were performed and adjusted for age, sex and time period. Among 100 584 patients (23% HFpEF, 23% HFmrEF, 53% HFrEF), median age (interquartile range) was 75 (66-82) and 36% were female. Of those who died within 5 years, most deaths were ascribed to cardiovascular (CV) causes across all ejection fraction (EF) categories. Within 5 years, HFpEF had higher adjusted risk of non-CV death (hazard ratio [HR] 1.33, 95% confidence interval [CI] 1.28-1.38, p < 0.001) and lower adjusted risk of CV death (HR 0.85, 95% CI 0.82-0.88, p < 0.001) compared to HFrEF. Ischaemic heart disease (IHD) and cancer were the most common causes of CV and non-CV death regardless of EF category. The incidence rate of CV death due to IHD was highest in HFrEF while incidence rates of CV death due to pulmonary vascular disease, stroke, valvular heart disease and atrial fibrillation increased with increasing EF. The incidence rates of non-CV deaths due to cancer, respiratory disease, and infections increased with increasing EF., Conclusion: Cardiovascular death was more common than non-CV death across all EF categories although the risk of non-CV death within 5 years was higher with increasing EF. IHD and cancer were the most common causes of CV and non-CV deaths, respectively, regardless of EF category., (© 2024 The Authors.

Background: The frequency of and relationship between hospital readmissions and outcomes after revascularization for left main coronary artery disease (LMCAD) are unknown., Objectives: The purpose of this study was to study the incidence, predictors, and clinical impact of readmissions following percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) for LMCAD., Methods: In the EXCEL (XIENCE Versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization) trial, 1,905 patients with LMCAD were randomized to PCI vs CABG. The cumulative incidence of readmissions was analyzed with multivariable Anderson-Gill and joint frailty models to account for recurrent events and the competing risk of death. The impact of readmission on subsequent mortality within 5-year follow-up was determined in a time-adjusted Cox proportional hazards model., Results: Within 5 years, 1,868 readmissions occurred in 851 of 1,882 (45.2%) hospital survivors (2.2 ± 1.9 per patient with readmission[s], range 1-16), approximately one-half for cardiovascular causes and one-half for noncardiovascular causes (927 [49.6%] and 941 [50.4%], respectively). One or more readmissions occurred in 463 of 942 (48.6%) PCI patients vs 388 of 940 (41.8%) CABG patients (P = 0.003). After multivariable adjustment, PCI remained an independent predictor of readmission (adjusted HR: 1.22; 95% CI: 1.10-1.35; P < 0.0001), along with female sex, comorbidities, and the extent of CAD. Readmission was independently associated with subsequent all-cause death, with interaction testing indicating a higher risk after PCI than CABG (adjusted HR: 5.72; 95% CI: 3.42-9.55 vs adjusted HR: 2.72; 95% CI: 1.64-4.88, respectively; P int  = 0.03)., Conclusions: In the EXCEL trial, readmissions during 5-year follow-up after revascularization for LMCAD were common and more frequent after PCI than CABG. Readmissions were associated with an increased risk of all-cause death, more so after PCI than with CABG., Competing Interests: Funding Support and Author Disclosures The EXCEL trial was funded by Abbott Vascular.

Background: Cholinesterase inhibitors (ChEIs) are the first-line symptomatic pharmacologic treatment for patients with mild-to-moderate Alzheimer's disease (AD). Although the target organ for this group of drugs is the brain, inhibition of the enzyme may affect cardiac function through vagotonic and anti-inflammatory effects., Objective: To assess the impact of ChEIs on outcomes in patients with AD who have experienced myocardial infarction (MI) prior to the AD diagnosis., Methods: Patients who had experienced MI before they were diagnosed with AD or Alzheimer's mixed dementia between 2008 and 2018 were identified from the Swedish Dementia Registry (SveDem, www.svedem.se), which was linked to the National Patient Registry to obtain data on MI and mortality. Cox proportional hazards regression model among a propensity score-matched dataset was performed to assess the association between ChEI treatment and clinical outcomes., Results: Of 3198 patients with previous MI and a diagnosis of AD or mixed dementia, 1705 (53%) were on treatment with ChEIs. Patients treated with ChEIs were more likely to be younger and have a better overall cardiovascular (CV) risk profile. The incidence rate of all-cause death (per 1000 patient-years) in the propensity-matched cohort of 1016 ChEI users and 1016 non-users was 168.6 in patients on treatment with ChEIs compared with 190.7 in patients not on treatment with ChEIs. In this propensity-matched cohort, treatment with ChEIs was associated with a significantly lower risk of all-cause death (adjusted hazard ratio 0.81, 95% confidence interval 0.71-0.92) and a greater reduction with higher doses of ChEIs. While in the unadjusted analysis, ChEIs were associated with a lower risk of both CV and non-CV death, only the association with non-CV death remained significant after accounting for baseline differences., Conclusion: Treatment with ChEIs was associated with a significantly reduced risk of all-cause death, driven by lower rates of non-CV death in a nationwide cohort of patients with previous MI and a diagnosis of AD or mixed dementia. These associations were greater with higher ChEI doses., Condensed Abstract: We assessed the association between cholinesterase inhibitors (ChEIs) and clinical outcomes in a nationwide cohort of patients with previous myocardial infarction (MI) and a diagnosis of Alzheimer's disease (AD) or mixed dementi. In propensity-matched analysis, treatment with ChEIs was associated with a 19% reduction in all-cause death driven by non-cardiovascular death. The reduction in all-cause death was greater with the higher doses of ChEIs., (© The Author(s) 2024. Published by Oxford University Press on behalf of the European Society of Cardiology.)

Heart failure (HF) is a global pandemic affecting 64 million people worldwide. HF with preserved ejection fraction (HFpEF) has traditionally received less attention than its main counterpart, HF with reduced ejection fraction (HFrEF). The incidence and prevalence of HFpEF show geographic variation and are increasing over time, soon expected to surpass those of HFrEF. Morbidity and mortality rates of HFpEF are considerable, albeit lower than those of HFrEF. This review focuses on the burden of HFpEF, providing contemporary data on epidemiology, clinical characteristics and comorbidities, cause-specific outcomes, costs and pharmacotherapy., Competing Interests: Disclosure: LHL has received grants from AstraZeneca, Vifor, Boston Scientific, Boehringer Ingelheim, Novartis and MSD; consulting fees from Vifor, AstraZeneca, Bayer, Pharmacosmos, MSD, Medscape, Sanofi, Lexicon, MyoKardia, Boehringer Ingelheim, Servier, Edwards Life Sciences and Alleviant; speaker honoraria from Abbott, Orion Pharma, Medscape, Radcliffe Group, AstraZeneca, Novartis, Boehringer Ingelheim and Bayer; patent and stock for AnaCardio; is a board member of Heart Failure Association of the ESC and Swedish Society of Cardiology, HF Working Group; and is on the Cardiac Failure Review editorial board; this did not influence peer review.

Heart failure (HF) is a rapidly growing public health issue with an estimated prevalence of 64 million people globally. Although the incidence of HF has stabilised worldwide and seems to be declining in developed countries, the prevalence is increasing due to the ageing of the population, improved survival after MI and improved treatment and survival of patients with HF. Yet, HF remains associated with high mortality and morbidity, poor quality of life and functional capacity, and confers a substantial burden to the healthcare system. The prevalence, incidence, mortality and morbidity rates reported show geographical variations, depending on the different aetiologies and clinical characteristics observed among patients with HF. In this review, we provide an overview of the global epidemiology of HF with updated data on prevalence, incidence, mortality and morbidity worldwide., Competing Interests: Disclosures: GS has received funding from Vifor Pharma, Boehringer Ingelheim, AstraZeneca, Merck, Cytokinetics, Novartis, Boston Scientific, Pharmacosmos, Bayer and Horizon; consulting fees from Teva, MedEd Global Solutions, Genesis Medical, Agence Nationale de la Recherche, Muir Health, Atheneum and Vifor Pharma; honoraria from Servier, Cytokinetics, Medtronic, Dynamicom Education, Vifor Pharma, Roche, TMA Healthcare Ltd, MedEd Global Solutions, AstraZeneca, Novartis; and has participated on advisory boards for AstraZeneca, Uppsala Clinical Research Center, Servier, Edwards and Vifor Pharma.

Aim: Mitral regurgitation (MR) and tricuspid regurgitation (TR) are common in patients with heart failure (HF). The aim of this study was to investigate prevalence, clinical characteristics and outcomes of patients with or without isolated or combined MR and TR across the entire HF spectrum., Methods and Results: The ESC-HFA EORP HF Long-Term Registry is a prospective, multicentre, observational study including patients with HF and 1-year follow-up data. Outpatients without aortic valve disease were included and stratified according to isolated or combined moderate/severe MR and TR. Among 11 298 patients, 7541 (67%) had no MR/TR, 1931 (17%) isolated MR, 616 (5.5%) isolated TR and 1210 (11%) combined MR/TR. Baseline characteristics were differently distributed across MR/TR categories. Compared to HF with reduced ejection fraction, HF with mildly reduced ejection fraction was associated with a lower risk of isolated MR (odds ratio [OR] 0.69; 95% confidence interval [CI] 0.60-0.80), and distinctly lower risk of combined MR/TR (OR 0.51; 95% CI 0.41-0.62). HF with preserved ejection fraction (HFpEF) was associated with a distinctly lower risk of isolated MR (OR 0.42; 95% CI 0.36-0.49), and combined MR/TR (OR 0.59; 95% 0.50-0.70), but a distinctly increased risk of isolated TR (OR 1.94; 95% CI 1.61-2.33). All-cause death, cardiovascular death, HF hospitalization and combined outcomes occurred more frequently in combined MR/TR, isolated TR and isolated MR versus no MR/TR. The highest incident rates were observed in isolated TR and combined MR/TR., Conclusion: In a large cohort of outpatients with HF, prevalence of isolated and combined MR and TR was relatively high. Isolated TR was driven by HFpEF and was burdened by an unexpectedly poor outcome., (© 2023 European Society of Cardiology.)

Aims: To assess the prevalence, clinical characteristics, and outcomes of patients with heart failure (HF) with or without moderate to severe aortic valve disease (AVD) (aortic stenosis [AS], aortic regurgitation [AR], mixed AVD [MAVD])., Methods and Results: Data from the prospective ESC HFA EORP HF Long-Term Registry including both chronic and acute HF were analysed. Of 15 216 patients with HF (62.5% with reduced ejection fraction, HFrEF; 14.0% with mildly reduced ejection fraction, HFmrEF; 23.5% with preserved ejection fraction, HFpEF), 706 patients (4.6%) had AR, 648 (4.3%) AS and 234 (1.5%) MAVD. The prevalence of AS, AR and MAVD was 6%, 8%, and 3% in HFpEF, 6%, 3%, and 2% in HFmrEF and 4%, 3%, and 1% in HFrEF. The strongest associations were observed for age and HFpEF with AS, and for left ventricular end-diastolic diameter with AR. AS (adjusted hazard ratio [HR] 1.43, 95% confidence interval [CI] 1.23-1.67), and MAVD (adjusted HR 1.37, 95% CI 1.07-1.74) but not AR (adjusted HR 1.13, 95% CI 0.96-1.33) were independently associated with the 12-month composite outcome of cardiovascular death and HF hospitalization. The associations between AS and the composite outcome were observed regardless of ejection fraction category., Conclusions: In the ESC HFA EORP HF Long-Term Registry, one in 10 patients with HF had AVD, with AS and MAVD being especially common in HFpEF and AR being similarly distributed across all ejection fraction categories. AS and MAVD, but not AR, were independently associated with increased risk of in-hospital mortality and 12-month composite outcome, regardless of ejection fraction category., (© 2023 The Authors.

Mitral regurgitation is the most common valvular disease and is estimated to affect over 5 million Americans. Real-world data collection contributes to safety and effectiveness evidence for the U.S. Food and Drug Administration, quality evaluation for the Centers for Medicare and Medicaid Services and hospitals, and clinical best practice research. We aimed to establish a minimum core data set in mitral interventions to promote efficient, reusable real-world data collection for all of these purposes. Two expert task forces separately evaluated and reconciled a list of candidate elements derived from: 1) 2 ongoing transcatheter mitral trials; and 2) a systemic literature review of high-impact mitral trials and U.S multicenter, multidevice registries. From 703 unique data elements considered, unanimous consensus agreement was achieved on 127 "core" data elements, with the most common reasons for exclusion from the minimum core data set being burden or difficulty in accurate assessment (41.2%), duplicative information (25.0%), and low likelihood of affecting outcomes (19.6%). After a systematic review and extensive discussions, a multilateral group of academicians, industry representatives, and regulators established and implemented into the national Society of Thoracic Surgery/American College of Cardiology Transcatheter Valve Therapies Registry 127 interoperable, reusable core data elements to support more efficient, consistent, and informative transcatheter mitral device evidence for regulatory submissions, safety surveillance, best practice development, and hospital quality assessments., Competing Interests: Funding Support and Author Disclosures Dr Vemulapalli has received grants/contracts from the American College of Cardiology, Society of Thoracic Surgeons, National Institutes of Health (R01 and SBIR), Food and Drug Administration (NEST cc), Abbott, Boston Scientific, and Cytokinetics; and is on the advisory board or is a consultant for Edwards Lifesciences, Medtronic, American College of Physicians, and Total CME.

Background Peripheral artery disease (PAD) and heart failure (HF) often coexist. Whether PAD influences outcomes of transcatheter mitral valve repair (TMVr) in patients with HF and severe secondary mitral regurgitation is unknown. The objectives are to assess the impact of PAD on outcomes of TMVr plus guideline-directed medical therapy (GDMT) versus GDMT alone in patients with HF and secondary mitral regurgitation. Methods and Results The COAPT trial (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation) randomized patients with HF with ≥moderate-to-severe secondary mitral regurgitation to TMVr with MitraClip implant plus GDMT versus GDMT alone. We evaluated the relationship between PAD and 2-year outcomes in the COAPT trial  and examined whether PAD modified the benefits of TMVr. Among 614 patients enrolled, 109 (17.8%) had PAD. By multivariable analysis, PAD was independently associated with 2-year mortality (adjusted hazard ratio [adjHR], 1.51 [95% CI, 1.07-2.15]) but not HF hospitalizations. Compared with GDMT alone, TMVr reduced the 2-year risk of death in patients without PAD (adjHR, 0.42 [95% CI, 0.30-0.60]) but not those with PAD (adjHR, 1.27 [95% CI, 0.72-2.27]; P interaction =0.001). In contrast, TMVr reduced HF hospitalizations consistently in patients with (adjHR, 0.65 [95% CI, 0.35-1.23]) and without (adjHR, 0.42 [95% CI, 0.31-0.57]) PAD ( P interaction =0.22). Improvements in health status and exercise capacity at 2 years with TMVr compared with GDMT alone were similar in degree, irrespective of PAD status ( P interaction =0.76 and 0.64, respectively). Conclusions In patients with HF and severe secondary mitral regurgitation, the reduced mortality with TMVr in the overall COAPT study population was not observed in the subgroup of patients with PAD. However, TMVr reduced HF hospitalizations and improved health status and exercise capacity consistently in patients with and without PAD.

Background Diabetes mellitus and high platelet reactivity (HPR) on clopidogrel are both associated with increased risk of ischemic events after percutaneous coronary intervention, but whether the HPR-associated risk of adverse ischemic events differs by diabetes mellitus status is unknown. Methods and Results ADAPT-DES (Assessment of Dual Antiplatelet Therapy With Drug-Eluting Stents) was a prospective, multicenter registry of patients treated with coronary drug-eluting stents. HPR was defined as P2Y12 reaction units >208 by the VerifyNow point-of-care assay. Cox multivariable analysis was used to assess whether HPR-associated risk of major adverse cardiac events (MACE; cardiac death, myocardial infarction, or stent thrombosis) varied for patients with insulin-treated diabetes mellitus (ITDM), non-ITDM, and no diabetes mellitus. Diabetes mellitus and HPR were included in an interaction analysis. Of 8582 patients enrolled, 2429 (28.3%) had diabetes mellitus, of whom 998 (41.1%) had ITDM. Mean P2Y12 reaction units were higher in patients with diabetes mellitus versus without diabetes mellitus, and HPR was more frequent in patients with diabetes mellitus. HPR was associated with consistently increased 2-year rates of MACE in patients with and without diabetes mellitus ( P interaction =0.36). A significant interaction was present between HPR and non-insulin-treated diabetes mellitus versus ITDM for 2-year MACE (adjusted hazard ratio [HR] for non-ITDM, 2.28 [95% CI, 1.39-3.73] versus adjusted HR for ITDM, 1.02 [95% CI, 0.70-1.50]; P interaction =0.01). Conclusions HPR was more common in patients with diabetes mellitus and was associated with an increased risk of MACE in both patients with and without diabetes mellitus. In patients with diabetes mellitus, a more pronounced effect of HPR on MACE was present in lower-risk non-ITDM patients than in higher-risk patients with ITDM.

In this article, we consider the impacts of the COVID-19 pandemic on Indigenous Peoples (IPs) by reporting on information-gathering work across two non-governmental and Indigenous organisations to compensate where federal systems failed. Strategies IPs have employed to understand and respond to the pandemic, and described here, include: collaborative efforts across communities intra- and inter-nationally; open-source data platforms; and small-scale epidemiological research. Our review exposes the informational politics faced by Indigenous organisations and communities, and their struggle to pursue needed resources or protections while avoiding the critiques of 'post-neoliberal' and 'science denialism'. We conclude by suggesting ways that Indigenous communities improve our understanding of their needs during public health crises, and maintain both informational and medical self-governance.

Aims/hypothesis: Established dysglycaemia (impaired glucose tolerance [IGT] or type 2 diabetes [T2DM]) is a risk factor for further cardiovascular events in patients with coronary artery disease. Sodium-glucose cotransporter 2 inhibitors reduce this risk. The aim of the present investigation was to test the hypothesis that empagliflozin exerts beneficial effects on myocardial function in patients with a recent acute coronary syndrome and newly detected dysglycaemia., Methods: Forty-two patients (mean age 67.5 years, 81 % male) with recent myocardial infarction (n = 36) or unstable angina (n = 6) and newly detected IGT (n = 27) or T2DM (n = 15) were randomised to 25 mg of empagliflozin daily (n = 20) or placebo (n = 22) on top of ongoing therapy. They were investigated with oral glucose tolerance tests, stress-perfusion cardiac magnetic resonance imaging (CMR) and echocardiography at three occasions: before randomisation, after seven months on study drug and three months following cessation of such drug. Primary outcome was a change in left ventricular (LV) end-diastolic volume (LVEDV) and secondary outcomes were a change in a) systolic and diastolic LV function; b) coronary flow reserve; c) myocardial extracellular volume (ECV) in non-infarcted myocardium; d) aortic pulse wave velocity., Results: Empagliflozin induced a significant decrease in fasting and post load glucose (p < 0.05) and body weight (p < 0.01). Empagliflozin did not influence LVEDV, LV systolic or mass indexes, coronary flow reserve, ECV or aortic pulse wave velocity. Echocardiographic indices of LV diastolic function (E/e' and mitral E/A ratio) were not influenced. No safety concerns were identified., Conclusions/interpretation: Empagliflozin had predicted effects on the dysglycaemia but did not influence variables expressing LV function, coronary flow reserve and ECV. An explanation may be that the LV function of the patients was within the normal range., 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 © 2022 The Author(s).

Background The neutrophil-to-lymphocyte ratio (NLR) as a marker of systemic inflammation has been associated with worse prognosis in several chronic disease states, including heart failure. However, few data exist on the prognostic impact of elevated baseline NLR or change in NLR levels during follow-up in patients undergoing transcatheter or surgical aortic valve replacement (TAVR or SAVR) for aortic stenosis. Methods and Results NLR was available in 5881 patients with severe aortic stenosis receiving TAVR or SAVR in PARTNER (Placement of Aortic Transcatheter Valves) I, II, and S3 trials/registries (median [Q1, Q3] NLR, 3.30 [2.40, 4.90]); mean NLR, 4.10; range, 0.5-24.9) and was evaluated as continuous variable and categorical tertiles (low: NLR ≤2.70, n=1963; intermediate: NLR 2.70-4.20, n=1958; high: NLR ≥4.20, n=1960). No patients had known baseline infection. High baseline NLR was associated with increased risk of death or rehospitalization at 3 years (58.4% versus 41.0%; adjusted hazard ratio [aHR], 1.39; 95% CI, 1.18-1.63; P <0.0001) compared with those with low NLR, irrespective of treatment modality. In both patients treated with TAVR and patients treated with SAVR, NLR decreased between baseline and 2 years. A 1-unit observed decrease in NLR between baseline and 1 year was associated with lower risk of death or rehospitalization between 1 year and 3 years (aHR, 0.86; 95% CI, 0.82-0.89; P <0.0001). Conclusions Elevated baseline NLR was independently associated with increased subsequent mortality and rehospitalization after TAVR or SAVR. The observed decrease in NLR after TAVR or SAVR was associated with improved outcomes.

Objectives: This study sought to assess the sex-specific outcomes in patients with heart failure (HF) with 3+ and 4+ secondary mitral regurgitation (SMR) treated with transcatheter mitral valve repair (TMVr) plus guideline-directed medical therapy (GDMT) versus GDMT alone in the COAPT trial., Background: The impact of sex in patients with HF and severe SMR treated with TMVr with the MitraClip compared with GDMT alone is unknown., Methods: Patients were randomized 1:1 to TMVr versus GDMT alone. Two-year outcomes were examined according to sex., Results: Among 614 patients, 221 (36.0%) were women. Women were younger than men and had fewer comorbidities, but reduced quality of life and functional capacity at baseline. In a joint frailty model accounting for the competing risk of death, the 2-year cumulative incidence of the primary endpoint of all HF hospitalizations (HFH) was higher in men compared with women treated with GDMT alone. However, the relative reduction in HFHs with TMVr was greater in men (HR: 0.43; 95% CI: 0.34-0.54) than women (HR: 0.78; 95% CI: 0.57-1.05) (P interaction  = 0.002). A significant interaction between TMVr versus GDMT alone treatment and time was present for all HFHs in women (HR: 0.57; 95% CI: 0.39-0.84, and HR: 1.39; 95% CI: 0.83-2.33 between 0-1 year and 1-2 years after randomization, respectively, P interaction  = 0.007) but not in men (HR: 0.48; 95% CI: 0.36-0.64, and HR: 0.33; 95% CI: 0.21-0.51; P interaction  = 0.16). Female sex was independently associated with a lower adjusted risk of death at 2 years (HR: 0.64; 95% CI: 0.46-0.90; P = 0.011). TMVr consistently reduced 2-year mortality compared with GDMT alone, irrespective of sex (P interaction  = 0.99)., Conclusions: In the COAPT trial, TMVr with the MitraClip resulted in improved clinical outcomes compared with GDMT alone, irrespective of sex. However, the impact of TMVr in reducing HFH was less pronounced in women compared with men beyond the first year after treatment.

Objectives: This paper sought to determine whether diabetes influences the outcomes of transcatheter mitral valve repair (TMVr) in patients with heart failure (HF) and secondary mitral regurgitation (SMR)., Background: Diabetes is associated with worse outcomes in patients with HF., Methods: The COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients With functional Mitral Regurgitation) trial randomized HF patients with 3+ or 4+ SMR to MitraClip plus guideline-directed medical therapy (GDMT) versus GDMT alone. Two-year outcomes were evaluated in patients with versus without diabetes., Results: Of 614 patients, 229 (37.3%) had diabetes. Diabetic patients had higher 2-year rates of death than those without diabetes (40.8% vs 32.3%, respectively; adjusted P = 0.04) and tended to have higher rates of HF hospitalization (HFH) (HFH: 50.1% vs 43.0%, respectively; adjusted P = 0.07). TMVr reduced the 2-year rate of death consistently in patients with (30.3% vs 49.9%, respectively; adjusted HR: 0.51; 95% CI: 0.32 to 0.81) and without (27.0% vs 38.3%, respectively; adjusted HR: 0.57; 95% CI: 0.39-0.84) diabetes (P interaction  = 0.72). TMVr also consistently reduced the 2-year rates of HFH in patients with (32.2% vs 54.8%, respectively; adjusted HR: 0.41; 95% CI: 0.28-0.58) and without (41.5% vs 59.0%, respectively; adjusted HR: 0.54: 95% CI 0.35-0.82) diabetes (P interaction  = 0.33). Greater movements in quality-of-life (QOL) and exercise capacity occurred with TMVr than with GDMT alone, regardless of diabetic status., Conclusions: Among HF patients with severe SMR in the COAPT trial, those with diabetes had a worse prognosis. Nonetheless, diabetic and nondiabetic patients had consistent reductions in the 2-year rates of death and HFH and improvements in QOL and functional capacity following TMVr treatment using the MitraClip than with maintenance on GDMT alone.

Objectives: The aim of this study was to assess the incidence and prognostic impact of early and late postoperative atrial fibrillation or flutter (POAF) in patients with severe aortic stenosis (AS) treated with transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR)., Background: There is an ongoing controversy regarding the incidence, recurrence rate, and prognostic impact of early (in-hospital) POAF and late (postdischarge) POAF in patients with AS undergoing TAVR or SAVR., Methods: In the PARTNER (Placement of Aortic Transcatheter Valve) 3 trial, patients with severe AS at low surgical risk were randomized to TAVR or SAVR. Analyses were performed in the as-treated population excluding patients with preexistent atrial fibrillation or flutter., Results: Among 781 patients included in the analysis, early POAF occurred in 152 (19.5%) (18 of 415 [4.3%] and 134 of 366 [36.6%] following TAVR and SAVR, respectively). Following discharge, 58 new or recurrent late POAF events occurred within 1 year following the index procedure in 55 of 781 patients (7.0%). Early POAF was not an independent predictor of late POAF following discharge (odds ratio: 1.04; 95% CI: 0.52-2.08; P = 0.90). Following adjustment, early POAF was not an independent predictor of the composite outcome of death, stroke, or rehospitalization (hazard ratio: 1.10; 95% CI: 0.64-1.92; P = 0.72), whereas late POAF was associated with an increased adjusted risk for the composite outcome (hazard ratio: 8.90; 95% CI: 5.02-15.74; P < 0.0001), irrespective of treatment modality., Conclusions: In the PARTNER 3 trial, early POAF was more frequent following SAVR compared with TAVR. Late POAF, but not early POAF, was significantly associated with worse outcomes at 2 years, irrespective of treatment modality., Competing Interests: Funding Support and Author Disclosures The PARTNER 3 trial was funded by Edwards Lifesciences.

Aims: Contemporary 2nd-generation thin-strut drug-eluting stents (DES) are considered standard of care for revascularization of patients undergoing percutaneous coronary intervention. A previous meta-analysis of 10 randomized controlled trials (RCTs) with 11 658 patients demonstrated a 16% reduction in the 1-year risk of target lesion failure (TLF) with ultrathin-strut DES compared with conventional 2nd-generation thin-strut DES. Whether this benefit is sustained longer term is not known, and newer trial data may inform these relative outcomes. We therefore sought to perform an updated systematic review and meta-analysis of RCTs comparing clinical outcomes with ultrathin-strut DES (≤70 µm strut thickness) with conventional 2nd-generation thin-strut DES., Methods and Results: We performed a random-effects meta-analysis of all RCTs comparing ultrathin-strut DES to conventional 2nd-generation thin-strut DES. The pre-specified primary endpoint was long-term TLF, a composite of cardiac death, myocardial infarction (MI), or clinically driven target lesion revascularization (CD-TLR). Secondary endpoints included the components of TLF, stent thrombosis (ST), and all-cause death. There were 16 eligible trials in which 20 701 patients were randomized. The weighted mean follow-up duration was 2.5 years. Ultrathin-strut DES were associated with a 15% reduction in long-term TLF compared with conventional 2nd-generation thin-strut DES [relative risk (RR) 0.85, 95% confidence interval (CI) 0.76-0.96, P = 0.008] driven by a 25% reduction in CD-TLR (RR 0.75, 95% CI 0.62-0.92, P = 0.005). There were no significant differences between stent types in the risks of MI, ST, cardiac death, or all-cause mortality., Conclusions: At a mean follow-up of 2.5 years, ultrathin-strut DES reduced the risk of TLF, driven by less CD-TLR compared with conventional 2nd-generation thin-strut DES, with similar risks of MI, ST, cardiac death, and all-cause mortality., (Published on behalf of the European Society of Cardiology.

The prognostic impact of preexisting atrial fibrillation or flutter (AF) in low-risk patients with severe aortic stenosis treated with transcatheter (TAVR) or surgical aortic valve replacement (SAVR) remains unknown. In this sub-analysis of the PARTNER 3 trial of patients with severe aortic stenosis at low surgical risk randomized 1:1 to TAVR versus SAVR, clinical outcomes were analyzed at 2 years according to AF status. Among 948 patients included in the analysis (452 [47.7%] in the SAVR vs 496 [52.3%] in the TAVR arm), 168 (17.6%) patients had AF [88/452 (19.5%) and 80/496 (16.1%) treated with SAVR and TAVR, respectively]. At 2 years, patients with AF had higher unadjusted rates of the composite outcome of death, stroke or rehospitalization (21.2% vs 12.9%, p = 0.007) and rehospitalization alone (15.3% vs 9.4%, p = 0.03) but not all cause death (3.8% vs 2.6%, p = 0.45) or stroke (4.8% vs 2.6%, p = 0.12). In adjusted analyses, patients with AF had a higher risk for the composite outcome of death, stroke or rehospitalization (hazard ratio [HR] 1.80, 95% confidence interval [CI] 1.20-2.71, p = 0.0046) and rehospitalization alone (HR 1.8, 95% CI 0.12-2.9, p = 0.015), but not death or stroke. There was no interaction between treatment modality and AF on the composite outcome (Pinter = 0.83). In conclusion, preexisting AF in patients with severe AS at low surgical risk was associated with increased risk of the composite outcome of death, stroke or rehospitalization at 2 years, irrespective of treatment modality., (Copyright © 2021 Elsevier Inc.

After 15 years of successive randomized, controlled trials, indications for transcatheter aortic valve replacement (TAVR) are rapidly expanding. In the coming years, this procedure could become the first line treatment for patients with a symptomatic severe aortic stenosis and a tricuspid aortic valve anatomy. However, randomized, controlled trials have excluded bicuspid aortic valve (BAV), which is the most frequent congenital heart disease occurring in 1% to 2% of the total population and representing at least 25% of patients 80 years of age or older referred for aortic valve replacement. The use of a less invasive transcatheter therapy in this elderly population became rapidly attractive, and approximately 10% of patients currently undergoing TAVR have a BAV. The U.S. Food and Drug Administration and the "European Conformity" have approved TAVR for low-risk patients regardless of the aortic valve anatomy whereas international guidelines recommend surgical replacement in BAV populations. Given this progressive expansion of TAVR toward younger and lower-risk patients, heart teams are encountering BAV patients more frequently, while the ability of this therapy to treat such a challenging anatomy remains uncertain. This review will address the singularity of BAV anatomy and associated technical challenges for the TAVR procedure. We will examine and summarize available clinical evidence and highlight critical knowledge gaps regarding TAVR utilization in BAV patients. We will provide a comprehensive overview of the role of computed tomography scans in the diagnosis, and classification of BAV and TAVR procedure planning. Overall, we will offer an integrated framework for understanding the current role of TAVR in the treatment of bicuspid aortic stenosis and for guiding physicians in clinical decision-making.

Background: Pulmonary hypertension worsens prognosis in patients with heart failure (HF) and secondary mitral regurgitation (SMR)., Objectives: This study sought to determine whether baseline pulmonary hypertension influences outcomes of transcatheter mitral valve repair (TMVr) in patients with HF with SMR., Methods: In the COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation) trial, 614 patients with HF with moderate-to-severe or severe SMR were randomized to TMVr with the MitraClip plus guideline-directed medical therapy (GDMT) (n = 302) versus GDMT alone (n = 312). Baseline pulmonary artery systolic pressure (PASP) estimated from echocardiography was categorized as substantially increased (≥50 mm Hg) versus not substantially increased (<50 mm Hg)., Results: Among 528 patients, 184 (82 TMVr, 102 GDMT) had PASP of ≥50 mm Hg (mean: 59.1 ± 8.8 mm Hg) and 344 (171 TMVr, 173 GDMT) had PASP of <50 mm Hg (mean: 36.3 ± 8.1 mm Hg). Patients with PASP of ≥50 mm Hg had higher 2-year rates of death or HF hospitalization (HFH) compared to those with PASP of <50 mm Hg (68.8% vs. 49.1%; adjusted hazard ratio: 1.52; 95% confidence interval: 1.17 to 1.97; p = 0.002). Rates of death or HFH were reduced by TMVr versus GDMT alone, irrespective of baseline PASP (p interaction  = 0.45). TMVr reduced PASP from baseline to 30 days to a greater than GDMT alone (adjusted least squares mean: -4.0 vs. -0.9 mm Hg; p = 0.006), a change that was associated with reduced risk of death or HFH between 30 days and 2 years (adjusted hazard ratio: 0.91 per -5 mm Hg PASP; 95% confidence interval: 0.86 to 0.96; p = 0.0009)., Conclusions: Elevated PASP is associated with a worse prognosis in patients with HF with severe SMR. TMVr with the MitraClip reduced 30-day PASP and 2-year rates of death or HFH compared with GDMT alone, irrespective of PASP., Competing Interests: Author Disclosures The COAPT trial was funded by Abbott.

Background: In the COAPT trial (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients With Functional Mitral Regurgitation), treatment of heart failure (HF) patients with moderate-severe or severe secondary mitral regurgitation with transcatheter mitral valve repair (TMVr) using the MitraClip plus guideline-directed medical therapy (GDMT) reduced 2-year rates of HF hospitalization and all-cause mortality compared with GDMT alone. Whether the benefits of the MitraClip extend to patients with previously implanted cardiac resynchronization therapy (CRT) is unknown. We sought to examine the effect of prior CRT in patients enrolled in COAPT., Methods: Patients (N=614) with moderate-severe or severe secondary mitral regurgitation who remained symptomatic despite maximally tolerated doses of GDMT were randomized 1:1 to the MitraClip (TMVr arm) versus GDMT only (control arm). Outcomes were assessed according to prior CRT use., Results: Among 614 patients, 224 (36.5%) had prior CRT (115 and 109 randomized to TMVr and control, respectively) and 390 (63.5%) had no CRT (187 and 203 randomized to TMVr and control, respectively). Patients with CRT had similar 2-year rates of the composite of death or HF hospitalization compared with those without CRT (57.6% versus 55%, P =0.32). Death or HF hospitalization at 2 years was lower with TMVr versus control treatment in patients with prior CRT (48.6% versus 67.2%, hazard ratio, 0.60 [95% CI, 0.42-0.86]) and without CRT (42.5% versus 66.9%, hazard ratio, 0.52 [95% CI, 0.39-0.69]; adjusted P interaction =0.23). The effects of TMVr with the MitraClip on reducing the 2-year rates of all-cause death (adjusted P interaction =0.14) and HF hospitalization (adjusted P interaction =0.82) were also consistent in patients with and without CRT as were improvements in quality-of-life and exercise capacity., Conclusions: In the COAPT trial, TMVr with the MitraClip improved the 2-year prognosis of patients with HF and moderate-severe or severe secondary mitral regurgitation who remained symptomatic despite maximally tolerated GDMT, regardless of prior CRT implantation.

Background: The presence of tricuspid regurgitation (TR) may affect prognosis in patients with mitral regurgitation (MR)., Objectives: This study sought to determine the impact of TR on outcomes in patients with heart failure and severe secondary MR randomized to guideline-directed medical therapy (GDMT) or edge-to-edge repair with the MitraClip in the COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients With Functional Mitral Regurgitation) trial., Methods: A total of 614 patients with symptomatic heart failure with moderate to severe (3+) or severe (4+) secondary MR were randomized to maximally tolerated GDMT plus MitraClip or GDMT alone; 599 had core laboratory evaluable echocardiograms. Patients were divided into 2 groups by baseline TR severity: none/trace/mild TR (≤Mild TR) (n = 501 [83.6%]) and moderate/severe TR (≥Mod TR) (n = 98 [16.4%]). Two-year composite endpoints of death or heart failure hospitalization (HFH) and the individual endpoints were analyzed., Results: Patients with ≥Mod TR were more likely to be New York Heart Association functional class III/IV (p < 0.0001) and have a Society of Thoracic Surgeons score of ≥8 (p < 0.0001), anemia (p = 0.02), chronic kidney disease (p = 0.003), and higher N-terminal pro-B-type natriuretic peptide (p = 0.02) than those with ≤Mild TR. Patients with ≥Mod TR had more severe MR (p = 0.0005) despite smaller left ventricular volumes (p = 0.005) and higher right ventricular systolic pressure (p < 0.0001). At 2 years, the composite rate of death or HFH was higher in patients with ≥Mod TR compared with ≤Mild TR treated with GDMT alone (83.0% vs. 64.3%; hazard ratio: 1.74; 95% confidence interval: 1.24 to 2.45; p = 0.001) but not following MitraClip (48.2% vs. 44.0%; hazard ratio: 1.14; 95% confidence interval: 0.71 to 1.84; p = 0.59). Rates of death or HFH, as well as death and HFH alone, were reduced by MitraClip compared with GDMT, irrespective of baseline TR grade (p interaction  = 0.16, 0.29, and 0.21 respectively)., Conclusions: Patients with severe secondary MR who also had ≥Mod TR had worse clinical and echocardiographic characteristics and worse clinical outcomes compared to those with ≤Mild TR. Within the COAPT trial, MitraClip improved outcomes in patients with and without ≥Mod TR severity compared with GDMT alone.

Cigarette smoking is a well-known risk factor for coronary artery disease (CAD). However, the impact of smoking on outcomes after coronary revascularization, especially in patients with left main CAD (LMCAD) is less well understood. The EXCEL trial randomized 1,905 patients with LMCAD and visually assessed low or intermediate anatomical complexity (SYNTAX score ≤32) to PCI with everolimus-eluting stents or CABG. Patients were categorized according to smoking status (current, former, or never), and their outcomes at 5 years were compared by logistic regression with follow-up time included as a log-transformed offset variable. The primary endpoint was a composite of death, myocardial infarction, or stroke. Among 1893 patients with known smoking status at baseline, 416 (22%) were current smokers and 774 (41%) were former smokers. The crude rates of the primary endpoint were 19.5% for never smokers, 20.5% for former smokers (p = 0.61 vs never smokers), and 23.1% for smokers (p = 0.15 vs never smokers). Compared with never smokers, the adjusted risk of the primary endpoint was higher for current smokers (adjOR 1.82, 95% confidence interval [CI] 1.126 to 2.63; p = 0.001), but not for former smokers (adjOR 1.00, 95% CI 0.75 to 1.33, p = 0.10). The relative efficacy of PCI versus CABG for the 5-year primary endpoint was similar irrespective of smoking status (P interaction  = 0.22). In conclusion, current smokers in the EXCEL trial had a higher adjusted 5-year risk of the primary composite endpoint of death, myocardial infarction, or stroke than never smokers, whereas former smokers were not at increased risk. Active smoking was a risk factor after LMCAD revascularization irrespective of revascularization method., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Objectives: The aim of this study was to examine the association between body mass index (BMI), infarct size (IS) and clinical outcomes., Background: The association between obesity, IS, and prognosis in patients undergoing primary percutaneous coronary intervention (pPCI) for ST-segment elevation myocardial infarction is incompletely understood., Methods: An individual patient-data pooled analysis was performed from 6 randomized trials of patients undergoing pPCI for ST-segment elevation myocardial infarction in which IS (percentage left ventricular mass) was assessed within 1 month (median 4 days) after randomization using either cardiac magnetic resonance (5 studies) or 99m Tc sestamibi single-photon emission computed tomography (1 study). Patients were classified as normal weight (BMI <25 kg/m 2 ), overweight (25 kg/m 2  ≤BMI <30 kg/m 2 ), or obese (BMI ≥30 kg/m 2 ). The multivariable models were adjusted for age, sex, hypertension, hyperlipidemia, current smoking, left main or left anterior descending coronary artery infarct, baseline TIMI (Thrombolysis In Myocardial Infarction) flow grade 0 or 1, prior myocardial infarction, symptom-to-first device time, and study., Results: Among 2,238 patients undergoing pPCI, 644 (29%) were normal weight, 1,008 (45%) were overweight, and 586 (26%) were obese. BMI was not significantly associated with IS, microvascular obstruction, or left ventricular ejection fraction in adjusted or unadjusted analysis. BMI was also not associated with the 1-year composite risk for death or heart failure hospitalization (adjusted hazard ratio: 1.21 [95% confidence interval: 0.74 to 1.71] for overweight vs. normal [p = 0.59]; adjusted hazard ratio: 1.21 [95% confidence interval 0.74 to 1.97] for obese vs. normal [p = 0.45]) or for death or heart failure hospitalization separately. Results were consistent when BMI was modeled as a continuous variable., Conclusions: In this individual patient-data pooled analysis of 2,238 patients undergoing pPCI for ST-segment elevation myocardial infarction, BMI was not associated with IS, microvascular obstruction, left ventricular ejection fraction, or 1-year rates of death or heart failure hospitalization., (Copyright © 2020 American College of Cardiology Foundation.

Background: Whether revascularization improves prognosis in stable ischemic heart disease is controversial., Methods: Individual patient-level data from 19 prospective, randomized stent trials were pooled. Rates of 5-year major adverse cardiovascular events (MACE; a composite of cardiac death, myocardial infarction, or ischemia-driven target lesion revascularization) were assessed and compared after percutaneous coronary intervention with bare-metal stents (BMS) and first-generation and second-generation drug-eluting stents (DES1 and DES2, respectively). Poisson multivariable regression analysis was performed to identify predictors of adverse events., Results: Among 10 987 patients treated with percutaneous coronary intervention for stable ischemic heart disease, 1550, 2776, and 6661 received BMS, DES1, and DES2, respectively. The 5-year rates of MACE progressively declined with evolution in stent technology (BMS: 24.1% versus DES1: 17.9% versus DES2: 13.4%, P <0.0001). However, MACE rates between 1 and 5 years increased from BMS to DES1, then declined with DES2 (BMS: 7.4% versus DES1: 10.2%, DES2: 8.5%, P =0.02)., Conclusions: Patients with stable ischemic heart disease remain at substantial risk for long-term MACE after revascularization with percutaneous coronary intervention, even with contemporary DES. New approaches to reduce the ongoing risk of MACE beyond 1 year after stent implantation are necessary.

Background: Peripheral arterial disease (PAD) is one of the most common manifestations of atherosclerotic disease worldwide. Peripheral arterial calcification reduces acute success and long-term patency of endovascular therapy for PAD. Several calcium modification devices are available for use in peripheral interventions. Outcomes after peripheral intravascular lithotripsy (IVL), a novel approach using pulsatile sonic waves to treat luminal and medial calcium in patients with PAD, have not been extensively characterized. Therefore, we sought to perform an individual patient-level data (IPD) pooled analysis of available studies to evaluate the efficacy and safety of IVL in the treatment of PAD., Methods and Results: We pooled IPD, including baseline and procedural variables, from five prospective studies which assessed IVL in the treatment of patients with extensive peripheral artery calcification. Final postprocedural percent diameter stenosis (%DS) and procedural angiographic complications were assessed by independent core laboratory. Efficacy endpoints were analyzed using linear mixed effects models and safety endpoints were tabulated overall and by vascular bed. Among 336 patients who underwent endovascular revascularization with use of IVL, there was a significant reduction between pre-procedural and final %DS of 55.1% (95% confidence interval 53.3-57.0%, p < .0001). Core-laboratory assessed lesion-level complications, including flow-limiting dissections (Types D-F), vessel perforation, distal embolization, thrombus, abrupt closure, and no reflow, occurred in 4/328 (1.22%) of treated lesions., Conclusions: The present IPD of five prospective studies, marking the largest analysis to date evaluating the use of IVL in significantly calcified PAD lesions, demonstrates this treatment strategy to be both effective and safe., (© 2020 The Authors.

Background: Phaeochromocytomas are rare catecholamine-producing tumours which typically present with comparatively benign symptoms such as headache, palpitations, sweating, hypertension, and insulin resistance. In rare cases, severe cardiac manifestations have been reported. We describe a patient who developed severe hypoglycaemia after an oral glucose tolerance test (OGTT), potentially triggering a phaeochromocytoma crisis and cardiogenic shock. To the best of our knowledge, only four other cases of hypoglycaemia after OGTT have been reported in patients with phaeochromocytoma, of which none developed a phaeochromocytoma crisis., Case Summary: A 53-year-old woman with hypertension, dyslipidaemia, and prediabetes presented to the Emergency Department with hypoxia, hyperglycaemia, lactic acidosis, severe left ventricular dysfunction, and pulmonary oedema followed by cardiogenic shock. Onset of symptoms was only few hours after an OGTT during which she had developed severe transient hypoglycaemia. Angiography was performed due to elevated troponin levels and showed a midventricular contraction pattern typical of takotsubo. This was subsequently confirmed by cardiac magnetic resonance imaging. The patient's condition improved during the first 36 h and she was discharged home on Day 7. A positive catecholamine test prompted readmission to the Endocrinology Unit, where computer tomography confirmed the diagnosis of phaeochromocytoma. An adrenalectomy was performed, and the diagnosis was verified histopathologically., Discussion: The possibility of a phaeochromocytoma must be considered as a potential triggering factor in patients presenting with takotsubo cardiomyopathy, in particular, when blood glucose levels fluctuate between severe hypo- and hyperglycaemia., (© The Author(s) 2019.

The EUROASPIRE surveys (EUROpean Action on Secondary Prevention through Intervention to Reduce Events) demonstrated that most European coronary patients fail to achieve lifestyle, risk factor and therapeutic targets. Here we report on the 2-year incidence of hard cardiovascular (CV) endpoints in the EUROASPIRE IV cohort. EUROASPIRE IV (2012-2013) was a large cross-sectional study undertaken at 78 centres from selected geographical areas in 24 European countries. Patients were interviewed and examined at least 6 months following hospitalization for a coronary event or procedure. Fatal and non-fatal CV events occurring at least 1 year after this baseline screening were registered. The primary outcome in our analyses was the incidence of CV death or non-fatal myocardial infarction, stroke or heart failure. Cox regression models, stratified for country, were fitted to relate baseline characteristics to outcome. Our analyses included 7471 predominantly male patients. Overall, 222 deaths were registered of whom 58% were cardiovascular. The incidence of the primary outcome was 42 per 1000 person-years. Comorbidities were strongly and significantly associated with the primary outcome (multivariately adjusted hazard ratio HR, 95% confidence interval): severe chronic kidney disease (HR 2.36, 1.44-3.85), uncontrolled diabetes (HR 1.89, 1.50-2.38), resting heart rate ≥ 75 bpm (HR 1.74, 1.30-2.32), history of stroke (HR 1.70, 1.27-2.29), peripheral artery disease (HR 1.48, 1.09-2.01), history of heart failure (HR 1.47, 1.08-2.01) and history of acute myocardial infarction (HR 1.27, 1.05-1.53). Low education and feelings of depression were significantly associated with increased risk. Lifestyle factors such as persistent smoking, insufficient physical activity and central obesity were not significantly related to adverse outcome. Blood pressure and LDL-C levels appeared to be unrelated to cardiovascular events irrespective of treatment. In patients with stabilized CHD, comorbid conditions that may reflect the ubiquitous nature of atherosclerosis, dominate lifestyle-related and other modifiable risk factors in terms of prognosis, at least over a 2-year follow-up period.

Background: Identifying type 2 diabetes mellitus (T2DM) is a prerequisite for the institution of preventive measures to reduce future micro and macrovascular complications. Approximately 50% of people with T2DM are undiagnosed, challenging the assumption that a traditional primary healthcare setting is the most efficient way to reach people at risk of T2DM. A setting of this kind may be even more suboptimal when it comes to reaching immigrants, who often appear to have inferior access to healthcare and/or are less likely to attend routine health checks at primary healthcare centres., Objectives: The objective of this study was to identify the best strategy to reach individuals at high risk of T2DM and thereby cardiovascular disease in a heterogeneous population., Methods: All 18-65-year-old inhabitants in the Swedish municipality of Södertälje ( n∼51,000) without known T2DM and cardiovascular disease were encouraged to complete the Finnish Diabetes Risk Score (FINDRISC: score > 15 indicating a high and > 20 a very high risk of future T2DM and cardiovascular disease) through the following communication channels: primary care centres, workplaces, Syrian orthodox churches, pharmacies, crowded public places, mass media, social media and mail. Data collection lasted for six weeks., Results: The highest response rate was obtained through workplaces (27%) and the largest proportion of respondents at high/very high risk through the Syrian orthodox churches (18%). The proportion reached through primary care centres was 4%, of whom 5% were at elevated risk. The cost of identifying a person at elevated risk through the Syrian orthodox church was €104 compared with €8 through workplaces and €112 through primary care centres., Conclusions: The choice of communication channels was important to reach high/very high-risk individuals for T2DM and for screening costs. In this immigrant-dense community, primary care centres were inferior to strategies using workplaces and churches in terms of both the proportion of identified at-risk individuals and costs.

Background: Point-of-care equipment for measuring glucose saves time and costs for both patients and professionals and minimizes preanalytic errors when screening for or managing dysglycemia, that is, impaired glucose tolerance and type 2 diabetes. The accuracy of such devices has, however, been questioned compared with analyses at an accredited hospital laboratory., Objective: To investigate the agreement between glucose measurements made by the point-of-care HemoCue ® Glucose 201 RT System (HemoCue, Ängelholm, Sweden) and local hospital laboratories., Material: Patients with established coronary artery disease (CAD) recruited in Sweden and the United Kingdom within the auspices of the European Action on Secondary and primary Prevention by Intervention to Reduce Events (EUROASPIRE) V survey (n = 87; 18-80 years) with or without previously known dysglycemia were investigated. Plasma glucose values collected in the fasting state (n = 85) and 60 (n = 57) and 120 (n = 72) min after a glucose load were analyzed both using HemoCue monitors and local hospital laboratories. The two measurement techniques were compared using a bias plot according to Bland-Altman, the surveillance error grid, and Spearman correlation test., Results: The bias plot method showed small differences between the HemoCue and local hospital laboratory methods, the HemoCue and central hospital laboratory, and the local hospital laboratories and the central hospital laboratory. In the surveillance error grid, 98.6% of the values were in the deep green zone, indicating no risk and the remaining values (1.4%) were within the light green zone, indicating "slight lower risk.", Conclusion: The HemoCue point-of-care system is accurate for dysglycemia screening in patients with CAD.

Background: Dysglycaemia defined as type 2 diabetes (T2DM) and impaired glucose tolerance (IGT), increases the risk of cardiovascular disease (CVD). The negative impact is more apparent in the presence of hypertension and/or dyslipidaemia. Thus, it seems reasonable to screen for dysglycaemia in patients treated for hypertension and/or dyslipidaemia. A simple screening algorithm would enhance the adoption of such strategy in clinical practice., Objectives: To test the hypotheses (1) that dysglycaemia is common in patients with hypertension and/or dyslipidaemia and (2) that initial screening with the Finnish Diabetes Risk Score (FINDRISC) will decrease the need for laboratory based tests., Methods: 2395 patients (age 18-80 years) without (i) a history of CVD or TDM2, (ii) prescribed blood pressure and/or lipid lowering drugs answered the FINDRISC questionnaire and had an oral glucose tolerance test (OGTT) and HbA1c measured., Results: According to the OGTT 934 (39%) had previously undetected dysglycaemia (T2DM 19%, IGT 20%). Of patients, who according to FINDRISC had a low, moderate or slightly elevated risk 20, 34 and 41% and of those in the high and very high-risk category 49 and 71% had IGT or T2DM respectively. The OGTT identified 92% of patients with T2DM, FPG + HbA1c 90%, FPG 80%, 2hPG 29% and HbA1c 22%., Conclusions: (1) The prevalence of dysglycaemia was high in patients treated for hypertension and/or dyslipidaemia. (2) Due to the high proportion of dysglycaemia in patients with low to moderate FINDRISC risk scores its initial use did not decrease the need for subsequent glucose tests. (3) FPG was the best test for detecting T2DM. Its isolated use is limited by the inability to disclose IGT. A pragmatic strategy, decreasing the demand for an OGTT, would be to screen all patients with FPG followed by OGTT in patients with IFG.

Objective: Three tests are recommended for identifying dysglycemia: fasting glucose (FPG), 2-h postload glucose (2h-PG) from an oral glucose tolerance test (OGTT), and glycated hemoglobin A 1c (HbA 1c ). This study explored the prognostic value of these screening tests in patients with coronary artery disease (CAD)., Research Design and Methods: FPG, 2h-PG, and HbA 1c were used to screen 4,004 CAD patients without a history of diabetes (age 18-80 years) for dysglycemia. The prognostic value of these tests was studied after 2 years of follow-up. The primary end point included cardiovascular mortality, nonfatal myocardial infarction, stroke, or hospitalization for heart failure and a secondary end point of incident diabetes., Results: Complete information including all three glycemic parameters was available in 3,775 patients (94.3%), of whom 246 (6.5%) experienced the primary end point. Neither FPG nor HbA 1c predicted the primary outcome, whereas the 2h-PG, dichotomized as <7.8 vs. ≥7.8 mmol/L, was a significant predictor (hazard ratio 1.38, 95% CI 1.07-1.78; P = 0.01). During follow-up, diabetes developed in 78 of the 2,609 patients (3.0%) without diabetes at baseline. An FPG between 6.1 and 6.9 mmol/L did not predict incident diabetes, whereas HbA 1c 5.7-6.5% and 2h-PG 7.8-11.0 mmol/L were both significant independent predictors., Conclusions: The 2h-PG, in contrast to FPG and HbA 1c , provides significant prognostic information regarding cardiovascular events in patients with CAD. Furthermore, elevated 2h-PG and HbA 1c are significant prognostic indicators of an increased risk of incident diabetes., (© 2017 by the American Diabetes Association.)

Cardiovascular disease is a major threat to people with diabetes. Attempts have long been made to lower cardiovascular risk by means of glucose-lowering treatment. Initially, it seemed that was an option, but subsequent trials could not verify the original observations and there was concern that some glucose-lowering drugs can actually cause cardiovascular harm. This led medical product agencies in the United States and Europe to require major outcomes trials before accepting new glucose-lowering drugs. The least requirement was noninferiority compared with existing treatment modalities. A large number of such trials have been performed or are ongoing, including >100,000 patients. The drug classes investigated are basal insulin, glucagon-like peptide-1 agonists, dipeptidyl peptidase 4 inhibitors, and sodium-glucose cotransporter-2 (SGLT2) inhibitors. This commentary discusses these trials and their outcomes, the reasons why several of them ended with neutral results (noninferiority), and that the likelihood for showing cardiovascular benefit was minor or even nonexistent. The surprising and highly rewarding impact of the SGLT2 inhibitor empagliflozin is described and potential mechanisms for cardiovascular benefits are discussed., (Copyright © 2016 Elsevier HS Journals, Inc.
