Covid-19 is a global pandemic that is wreaking havoc with the health and economy of much of human civilization. Electrophysiologists have been impacted personally and professionally by this global catastrophe. In this joint document from representatives of the HRS, ACC and AHA we identify the potential risks of exposure to patients, allied health care staff, industry representatives and hospital administrators. We describe the impact of COVID-19 on cardiac arrhythmias and methods of triage based on acuity and patient comorbidities...

Background: The terminology "end-stage" has been used to describe hypertrophic cardiomyopathy (HCM) with left ventricular systolic dysfunction (herein referred to as HCM-LVSD), defined when left ventricular ejection fraction (LVEF) <50% is present. The prognosis of HCM-LVSD has reportedly been poor, but due to its relative rarity, natural history remains incompletely characterized. Methods: Data from eleven high-volume HCM specialty centers comprising the international Sarcomeric Human Cardiomyopathy Registry (SHaRe) were used to describe the natural history of patients with HCM-LVSD...

Background: Patients with acute coronary syndrome (ACS) are at risk for peripheral artery disease (PAD) events and venous thromboembolism (VTE). Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors reduce lipoprotein(a) and low-density lipoprotein cholesterol (LDL-C) levels. Our objective was to ascertain whether PCSK9 inhibition reduces the risk of PAD events or VTE after ACS, and if such effects are related to levels of lipoprotein(a) or LDL-C. Methods: This was a prespecified analysis of the ODYSSEY OUTCOMES randomized clinical trial, which was conducted in 18 924 patients with recent ACS on intensive or maximum-tolerated statin treatment who were randomized to the PCSK9 inhibitor alirocumab or placebo...

Background: In AUGUSTUS, patients with atrial fibrillation (AF) and a recent acute coronary syndrome (ACS) and/or those undergoing percutaneous coronary intervention (PCI) had less bleeding with apixaban than vitamin K antagonist (VKA) and with placebo than aspirin, however, the number of ischemic events was numerically higher with placebo. The aim of this analysis is to assess the tradeoff of risk (bleeding) and benefit (ischemic events) over time with apixaban versus VKA and aspirin versus placebo. Methods: In AUGUSTUS, 4614 patients with AF and recent ACS and/or PCI on a P2Y12 inhibitor were randomized to blinded aspirin or placebo and to open-label apixaban or VKA for 6 months...

Background: The relationship between cholesterol levels and risk of venous thromboembolism (VTE) is uncertain. We set out to determine the effect of PCSK9 inhibition on the risk of VTE, explore potential mechanisms, and examine the efficacy in clinically and genetically defined risk subgroups. Methods: We performed a post-hoc analysis of the FOURIER trial testing whether evolocumab reduces the risk of VTE events (deep venous thrombosis or pulmonary embolism). Data from FOURIER and ODYSSEY OUTCOMES were then combined in a meta-analysis to assess class effect of PCSK9 inhibition on the risk of VTE...

Background: Non-rheumatic valvular heart diseases (NRVDs) are common; however, no studies have estimated their global or national burden. As part of the Global Burden of Disease (GBD) 2017 study, mortality, prevalence, and disability-adjusted life years (DALYs) for calcific aortic valve disease (CAVD), degenerative mitral valve disease (DMVD), and other NRVD were estimated for 195 countries and territories from 1990 to 2017. Methods: Vital registration data, epidemiological survey data, and administrative hospital data were used to estimate disease burden using the GBD modeling framework, which ensures comparability across locations...

Background: Patients with established coronary artery disease (CAD) or peripheral artery disease (PAD) often have diabetes mellitus. These patients are at high risk of future vascular events. Methods: In a prespecified analysis of the COMPASS trial, we compared the effects of rivaroxaban (2.5 mg twice daily) plus aspirin (100 mg daily) versus placebo plus aspirin in patients with diabetes versus without diabetes in preventing major vascular events. The primary efficacy endpoint was the composite of cardiovascular death, myocardial infarction (MI), or stroke...

Background: Branched-chain amino acids (BCAAs), essential nutrients including leucine, isoleucine and valine, serve as a resource for energy production and the regulator of important nutrient and metabolic signals. Recent studies have suggested that dysfunction of BCAA catabolism is associated with a risk of cardiovascular disease. Platelets play an important role in cardiovascular disease, but the functions of BCAA catabolism in platelets remain unknown. Methods: The activity of human platelets from healthy subjects before and after ingestion of BCAAs were measured...

Background: Pulmonary arterial hypertension (PAH) is a lethal vasculopathy. Hereditary cases are associated with germline mutations in BMPR2 and 16 other genes. However, these mutations occur in under 25% of idiopathic PAH patients (IPAH) and are rare in PAH associated with connective tissue diseases (APAH). Preclinical studies suggest epigenetic dysregulation, including altered DNA methylation, promotes PAH. Somatic mutations of Tet-methylcytosine-dioxygenase-2 ( TET2 ), a key enzyme in DNA demethylation, occur in cardiovascular disease and are associated with clonal hematopoiesis, inflammation and adverse vascular remodeling...
