BACKGROUND: Stopping aspirin within 1 month after implantation of a drug-eluting stent for ticagrelor monotherapy has not been exclusively evaluated for patients with acute coronary syndrome. The aim of this study was to investigate whether ticagrelor monotherapy after <1 month of dual antiplatelet therapy (DAPT) is noninferior to 12 months of ticagrelor-based DAPT for adverse cardiovascular and bleeding events in patients with acute coronary syndrome. METHODS: In this randomized, open-label,

Importance: In patients with coronary artery disease, some guidelines recommend initial statin treatment with high-intensity statins to achieve at least a 50% reduction in low-density lipoprotein cholesterol (LDL-C). An alternative approach is to begin with moderate-intensity statins and titrate to a specific LDL-C goal. These alternatives have not been compared head-to-head in a clinical trial involving patients with known coronary artery disease. Objective: To assess whether a treat-to-target

The need for further advances in drug-eluting stents or fully bioresorbable coronary scaffolds still exists to improve patient survival or clinical outcomes. The use for different actions or of combinations of drugs with several actions can be potential. Technological refinement and progress in manufacturing to improve mechanical integrity are needed, particularly for fully bioresorbable scaffolds. For antiplatelet therapy after stenting, clinical bleeding reduction strategies, such as a shorten

BACKGROUND: Modulation of intracellular free calcium is a critical determinant of vasomotor tone. The authors investigated the effects of three benzodiazepines on alpha-adrenergic-induced oscillations in intracellular free calcium in individual pulmonary artery smooth muscle cells. METHODS: Pulmonary artery smooth muscle cells were cultured from explants of canine intrapulmonary artery. Fura-2-loaded pulmonary artery smooth muscle cells were continuously superfused with phenylephrine (10 microM)

Importance: High-intensity statin is strongly recommended in patients at very high risk (VHR) of atherosclerotic cardiovascular disease (ASCVD). However, concerns about statin-associated adverse effects result in underuse of this strategy in practice. Objective: To evaluate the outcomes of a moderate-intensity statin with ezetimibe combination in VHR and non-VHR patients with ASCVD. Design, Setting, and Participants: This was a post hoc analysis of the Randomized Comparison of Efficacy and Safet
