Atherosclerotic cardiovascular disease (ASCVD), a leading cause of mortality and morbidity, is associated with a substantial healthcare and economic burden. Reduction of low-density lipoprotein cholesterol (LDL-C) to guideline-recommended goals is crucial in the prevention or management of ASCVD, particularly in those at high risk. Despite the availability of several effective lipid-lowering therapies (LLTs), up to 80% of patients with ASCVD do not reach evidence-based LDL-C goals.

Background: The PIONEER III trial showed the 12-month safety and efficacy of the Supreme drug-eluting stent (DES) vs the durable polymer everolimus-eluting stent. We sought to assess whether the characteristics and clinical outcomes of the Supreme DES in PIONEER III were consistent among patients by enrollment location.
Methods: This subgroup analysis of the PIONEER III trial compared the characteristics and outcomes of patients recruited from North America, Europe, and Japan and the relative differences in patient outcomes according to the site recruitment volume.
Aims: Harmonized Assessment by Randomized Multicentre Study of OrbusNEich's Combo StEnt (HARMONEE) (NCT02073565) was a randomized pivotal registration trial of the Combo stent, which combined sirolimus and an abluminal bioabsorbable polymer with a novel endoluminal anti-CD34+ antibody coating designed to capture endothelial progenitor cells (EPC) and promote percutaneous coronary intervention (PCI) site healing.
Methods And Results: Clinically stabilized PCI subjects were randomized 1:1 to receive Combo or everolimus-eluting stents (EES). Between February 2014 and June 2016, 572 subjects with 675 coronary lesions underwent 1-year angiography and fractional flow reserve, with optical coherence tomography (OCT) in the first 140 patients.
Significant progress has been made in the percutaneous coronary intervention technique from the days of balloon angioplasty to modern-day metallic drug-eluting stents (DES). Although metallic stents solve a temporary problem of acute recoil following balloon angioplasty, they leave behind a permanent problem implicated in very late events (in addition to neoatherosclerosis). BRS were developed as a potential solution to this permanent problem, but the promise of these devices has been tempered by clinical trials showing increased risk of safety outcomes, both early and late.

Background: Despite advances in interventional techniques, treatment of calcified coronary lesions remains a challenge. Stent placement in these lesions may result in stent underexpansion, malapposition, and procedural complications.
Background: The long-term impact of treating de novo coronary lesions in native vessels and challenging small vessel and long lesion subsets with TAXUS Liberté stents is unknown. This report examines the 3-year efficacy and safety from the TAXUS ATLAS program.
Methods And Results: TAXUS ATLAS WH, Small Vessel, and Long Lesion are non-randomized studies comparing TAXUS Liberté (n = 871), TAXUS Liberté 2.
This article reviews the precautions and adverse effects associated with vesnarinone use, and the potential mechanisms responsible for these complications as well as suggested treatment strategies. Vesnarinone, a quinolinone derivative, improves the haemodynamics and quality of life in patients with congestive heart failure (CHF); however, it is associated with the adverse effects of increased sudden cardiac death and neutropenia. These adverse effects have limited the application of vesnarinone to the general population but perhaps with continued research into vesnarinone-induced neutropenia and advances in arrhythmia management, the risk/ benefit ratio of vesnarinone may become favourable.

One hundred ninety-eight patients (39 with acute myocardial infarction) received aspirin 325 mg orally, clopidogrel 300 mg orally, enoxaparin 0.5 mg/kg intravenous (IV), and eptifibatide using the ESPIRIT dosing (180 g/kg bolus IV, immediately followed by a 2 g/kg/minute continuous IV infusion, and then a second 180 g/kg bolus IV ten minutes after the first bolus).
