Results of Bococizumab, A Monoclonal Antibody Against Proprotein Convertase Subtilisin/Kexin Type 9, from a Randomized, Placebo-Controlled, Dose-Ranging Study in Statin-Treated Subjects With Hypercholesterolemia
Bococizumab is a humanized monoclonal antibody binding proprotein convertase subtilisin/kexin type 9, which may be a potential therapeutic option for reducing low-density lipoprotein cholesterol (LDL-C) levels in patients with hypercholesterolemia. In this 24-week, multicenter, double-blind, placebo-controlled, dose-ranging study (NCT01592240), subjects with LDL-C levels ≥80 mg/dl on stable statin therapy were randomized to Q14 days subcutaneous placebo or bococizumab 50, 100, or 150 mg or Q28 days subcutaneous placebo or bococizumab 200 or 300 mg.Gender Disparities in Evidence-Based Statin Therapy in Patients With Cardiovascular Disease
Studies have shown gender disparities in cholesterol care in patients with cardiovascular disease (CVD), with women less likely than men to have low-density lipoprotein cholesterol levels <100 mg/dl. Whether this is related to a lower evidence-based statin or high-intensity statin use is not known. We used a national cohort of 972,532 patients with CVD (coronary heart disease, peripheral artery disease, and ischemic stroke) receiving care in 130 Veterans Health Administration facilities from October 1, 2010, to September 30, 2011, to identify the proportion of male and female patients with CVD receiving any statin and high-intensity statin.Comparison by Meta-Analysis of Mortality After Isolated Coronary Artery Bypass Grafting in Women Versus Men
Short- and long-term mortality in women who undergo coronary artery bypass grafting (CABG) has been evaluated in multiple studies with conflicting results. The investigators conducted a meta-analysis of all existing studies to evaluate the impact of female gender on mortality in patients who undergo isolated CABG. A comprehensive search of studies published through May 31, 2012 identified 20 studies comparing men and women who underwent isolated CABG. All-cause mortality was evaluated at short-term (postoperative period and/or at 30 days), midterm (1-year), and long-term (5-year) follow-up.Outcomes of Preoperative Angiotensin-Converting Enzyme Inhibitor Therapy in Patients Undergoing Isolated Coronary Artery Bypass Grafting
The association between preoperative use of angiotensin-converting enzyme (ACE) inhibitors and outcomes after coronary artery bypass grafting (CABG) remain controversial. Our aim was to study in-hospital outcomes after isolated CABG in patients on preoperative ACE inhibitors. A retrospective analysis of 8,889 patients who underwent isolated CABG from 2000 through 2011 was conducted. The primary outcome of interest was the incidence of major adverse events (MAEs) defined as a composite of mortality, postoperative renal dysfunction, myocardial infarction, stroke, and atrial fibrillation during index hospitalization.Usefulness of Single Nucleotide Polymorphism in Chromosome 4q25 to Predict In-Hospital and Long-Term Development of Atrial Fibrillation and Survival in Patients Undergoing Coronary Artery Bypass Grafting
We aimed to determine whether polymorphisms in chromosome 4q25 are associated with postoperative atrial fibrillation (AF), long-term AF, postoperative or long-term stroke, and long-term survival after coronary artery bypass grafting. We performed genotyping for rs2200733 and rs10033464 in white participants (n = 1,166) from the TexGen genetic registry. The development of postoperative or long-term AF, postoperative or long-term stroke, and long-term mortality were ascertained. Both rs2200733 and rs10033464 were associated with postoperative AF (odds ratio [OR] 1.41, 95% confidence interval [CI] 1.04 to 1.91, and OR 1.47, 95% CI 1.05 to 2.06, respectively).
