Background: Patients with bicuspid aortic valve (AV) stenosis were excluded from the pivotal evaluations of transcatheter AV replacement (TAVR) devices. We sought to evaluate the outcomes of TAVR in patients with bicuspid AV stenosis in comparison with those with tricuspid AV stenosis.
Methods: We used data from the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry (November 2011 through November 2018) to determine device success, procedural outcomes, post-TAVR valve performance, and in-hospital clinical outcomes (mortality, stroke, and major bleeding) according to valve morphology (bicuspid versus tricuspid).
Background: The relationship between culprit vessel, infarct size, and outcomes in non-ST-segment elevation acute coronary syndromes (NSTE ACS) is unclear. In some reports, the left circumflex artery (LCX) was more often the culprit at angiography than the right coronary artery (RCA) or left anterior descending artery (LAD), and infarcts were larger with LCX culprits.
Methods: We determined culprit vessel frequency and initial patency (TIMI flow grade), median fold elevation of peak troponin above the upper limit of normal, and outcomes (30-day death or myocardial infarction [MI] and 1-year mortality) by culprit vessel in high-risk NSTE ACS patients in the EARLY ACS trial.
Background: Adequate representation by sex in trials allows generalizability of results. We examined representation of women in clinical trials during a 17-year period in which inclusion criteria were broadened and federal mandates for representativeness were launched.
Methods And Results: Using mixed models, we studied sex-stratified temporal trends in enrollment, clinical characteristics, treatment, and outcomes among 76 148 non-ST-segment elevation acute coronary syndrome patients using patient-level data merged from 11 phase III trials conducted from 1994 to 2010.
Background: Discordant results have been reported on the effects of concomitant use of proton pump inhibitors (PPIs) and dual antiplatelet therapy (DAPT) for cardiovascular outcomes. We conducted a systematic review comparing the effectiveness and safety of concomitant use of PPIs and DAPT in the postdischarge treatment of unstable angina/non-ST-segment-elevation myocardial infarction patients.
Methods And Results: We searched for clinical studies in MEDLINE, EMBASE, and the Cochrane Database of Systematic Reviews, from 1995 to 2012.
Background: Although individual protein biomarkers are associated with cardiovascular risk, rarely have multiple proteins been considered simultaneously to identify which set of proteins best predicts risk.
Methods And Results: In a nested case-control study of 273 death/myocardial infarction (MI) cases and 273 age- (within 10 years), sex-, and race-matched and event-free controls from among 2023 consecutive patients (median follow-up 2.5 years) with suspected coronary disease, plasma levels of 53 previously reported biomarkers of cardiovascular risk were determined in a core laboratory.
Currently, there is a lack of consensus among guidelines for the postdischarge treatment of patients presenting with acute coronary syndrome (ACS) who have a long-term indication for anticoagulation. We conducted a systematic review comparing the safety and effectiveness of dual antiplatelet therapy (DAPT) and triple therapy (TT; defined as DAPT plus an oral anticoagulant) in patients with ACS and a long-term indication for anticoagulation. We searched for clinical studies in MEDLINE, EMBASE, and the Cochrane Database of Systematic Reviews published between January 1995 and September 2013.

Degenerative calcific pathology, the most common cause of aortic stenosis, increases in prevalence with age; estimated prevalence of 5% in individuals over 75 years of age. Despite the malignant prognosis without valve replacement, many patients are not offered surgery due to advanced age and co-existing medical conditions; reported to be a third of symptomatic patients.

Biomarkers are a critical component of patient selection, end point definition, and safety monitoring, and clinical trials provide a platform for the discovery and validation of new biomarkers that may augment the understanding of disease mechanisms, risk stratification, and/or clinical decision-making.
Content: We review the roles that biomarkers have played in CV clinical trials and roles that CV clinical trials have played and will continue to play in the discovery and validation of biomarkers and their implementation in clinical practice.

Acute coronary syndromes (ACS) continue to have a large impact on morbidity and mortality in the United States. Over the last two decades, there have been several advancements in the care of patients with ACS. The use of combined antiplatelet and anticoagulants and early invasive risk stratification in high risk patients has improved the rates of major adverse cardiovascular events.

Uncorrected survival to adult age is rare. We present a 77-year-old individual with anomalous right coronary artery from the pulmonary artery (ARCAPA), diagnosed by coronary angiography, whose clinical presentation was governed by coexisting obstructive atherosclerotic coronary disease.

Using the CRUSADE database, we explored relationships between sex and treatment and outcomes among patients with troponin 1 to 1.

Coronary disease is the leading killer of individuals worldwide and a leading cause of healthcare expenditure. On a global scale, ischemic heart disease kills over 6 million individuals each year and is projected by the World Health Organization to be the greatest single-disease cause of death worldwide by an increasing margin into 2030. Nearly 17 million Americans (7.
