Right ventricular (RV) pacing has been linked with lead-induced tricuspid regurgitation (TR), left ventricular (LV) dysfunction, and dyssynchrony, but the effect of pacing on RV function is unclear. We sought…
Decreases in systolic blood pressure during exercise may predispose to arrhythmias such as atrial fibrillation (AF) because of underlying abnormal autonomic tone. We examined the association between systolic blood pressure…
Identification of precursors of atrial fibrillation (AF) may lead to early detection and prevent associated morbidity and mortality. This study aimed to examine the association between frequent atrial premature complexes…
Mechanisms of acute myocardial infarction and nonobstructed coronary arteries (MINOCA) are incompletely understood. Myocardial bridging (MB) is usually considered a benign congenital variant, but serious complications have been reported. MB…
Quinidine, a class IA antiarrhythmic drug (AAD), has been used for the treatment of arrhythmias since the early 1900s. Use has decreased recently because of the availability of newer AADs…
Recent American College of Cardiology/American Heart Association guidelines on statin initiation on the basis of total atherosclerotic cardiovascular disease risk argue that the preventive effect of statins on cardiovascular events…
This prospective study assessed whether gender differences in health insurance help explain gender differences in delay in seeking care for patients in the US, with acute myocardial infarction (AMI). We…
Although the appropriate use criteria incorporate common clinical scenarios for coronary revascularization, a significant proportion of patients with stable coronary artery disease (CAD) cannot be assigned an appropriateness score. Our…
This study sought to evaluate the short-term and 3-year outcomes of polytetrafluoroethylene-covered stent (PCS) for patients with coronary perforation. Implantation of a PCS has improved the immediate clinical outcomes of…
As old patients, who were treated by percutaneous coronary interventions (PCI) for ST-segment elevation myocardial infarction (STEMI), are regularly excluded or underrepresented in randomized trials, data on treatment and outcomes…
