Coronary artery bypass grafting (CABG) has been considered the standard of care for patients with three-vessel disease (3VD), but long-term comparative results from randomized trials CABG vs. percutaneous coronary intervention (PCI) using drug-eluting stents (DES) remain limited. Patients de novo 3VD or left main were randomly assigned to PCI paclitaxel-eluting first-generation stent in SYNTAX trial. This pre-specified analysis presents 5-year outcomes (n = 1095). The rate major adverse...

Importance Drug-coated balloons offer a potentially beneficial treatment strategy for the management of coronary in-stent restenosis. However, none have been previously evaluated or approved use in circulation United States. Objective To evaluate whether paclitaxel-coated balloon is superior to an uncoated patients with restenosis undergoing percutaneous intervention. Design, Setting, and Participants AGENT IDE, multicenter randomized clinical trial, enrolled 600 (lesion length...

Background: Prolonged dual antiplatelet therapy (DAPT) after percutaneous coronary intervention is associated with increased bleeding, despite a reduced incidence of ischemic events. The SYNERGY everolimus-eluting stent thin-strut platinum-chromium that elutes everolimus from thin abluminal layer bioabsorbable polymer. These design elements may facilitate rapid endothelialization and enable shorter-duration DAPT. Methods: EVOLVE Short DAPT prospectively evaluated the safety 3-month in high...

African American individuals are at a higher risk of premature death from cardiovascular diseases than White individuals, with disproportionate attributable uncontrolled hypertension. Given their high use among mobile technologies, including smartphones, show promise in increasing reliable health information access. Culturally tailored (mHealth) interventions may promote hypertension self-management this population.

Small reference vessel diameter predicts adverse outcomes following coronary stenting. TAXUS Express and Liberté paclitaxel-eluting stents (PES) reduce restenosis compared to bare metal (BMS) in small vessels. Element is a novel thin-strut, platinum chromium stent designed enhance visibility, conformability, drug delivery vessels.The PERSEUS Vessel (SV) prospective, single-arm, superiority trial evaluates the PES 224 subjects with target lesion length≤20 mm diameter≥2.25 <2.75 mm, 125...
