Human or recombinant apolipoprotein A-I (apoA-I) has been shown to increase high-density lipoprotein-mediated cholesterol efflux capacity and regress atherosclerotic disease in animal clinical studies. CSL112 is an infusible, plasma-derived apoA-I that studied normal subjects those with stable coronary artery disease. This study aimed characterize the safety, tolerability, pharmacokinetics, pharmacodynamics of patients a recent acute myocardial infarction.The AEGIS-I trial (Apo-I Event...

Patients with atrial fibrillation who undergo intracoronary stenting traditionally are treated a vitamin K antagonist (VKA) plus dual antiplatelet therapy (DAPT), yet this treatment leads to high risks of bleeding. We hypothesized that regimen rivaroxaban P2Y12 inhibitor monotherapy or DAPT could reduce bleeding and thereby have favorable impact on all-cause mortality the need for rehospitalization.Stented subjects nonvalvular (n=2124) were randomized 1:1:1 administration reduced-dose 15 mg...

Stroke is a morbid and potentially mortal complication among patients hospitalized with acute medical illness. The potential of extended-duration thromboprophylaxis the factor Xa inhibitor betrixaban to reduce risk stroke compared standard-dose enoxaparin in this population was assessed retrospective APEX trial substudy (Acute Medically Ill Venous Thromboembolism Prevention With Extended Duration Betrixaban).Hospitalized acutely medically ill subjects (n=7513) were randomized double-dummy...

Background Extended‐duration betrixaban showed a significant reduction in venous thromboembolism the APEX trial (Acute Medically Ill VTE Prevention With Extended Duration Betrixaban Study). Given variable clinical impact of different efficacy and safety events, one approach to assess net outcomes is include only those events that are either fatal or cause irreversible harm. Methods Results This was post hoc analysis trial—a multicenter, double‐blind, randomized controlled comparing...

Abstract Background Self-reported time spent standing has been associated with lower risk of mortality. No previous studies have examined this association using device-measured standing. Method This was a prospective cohort study 5878 older (median age = 80 years), racial/ethnically diverse, community-dwelling women in the WHI Objective Physical Activity and Cardiovascular Health Study (OPACH). Women wore accelerometers for 1 week were followed The applied previously validated machine...

Despite dual antiplatelet therapy, persistent thrombin generation and thrombin-mediated platelet activation account in part for the residual risk of atherothrombotic disease among patients with prior acute coronary syndrome (ACS). Inhibition high-risk ACS (biomarker-positive ACS) factor Xa inhibitor rivaroxaban may limit ongoing thrombus formation myocardial necrosis thereby improve clinical outcomes.ATLAS 2-TIMI 51 was a double-blind, placebo-controlled trial that randomized to either 2.5...
