OBJECTIVES This study sought to examine the contemporary incidence, predictors and outcomes of acute kidney injury in patients undergoing percutaneous coronary interventions. BACKGROUND Acute kidney injury (AKI) is a serious and potentially preventable complication of percutaneous coronary interventions (PCIs) that is associated with adverse outcomes. The(More)
IMPORTANCE Bleeding is the most common complication after percutaneous coronary intervention (PCI) and is associated with increased morbidity and health care costs. The incidence of bleeding-related mortality after PCI has not been described in a nationally representative population. Furthermore, the relationships among bleeding risk, bleeding site, and(More)
We assessed the cardiovascular safety of liraglutide, a glucagon-like peptide-1 receptor agonist, using existing clinical data. Patient-level results from all completed phase 2 and 3 studies from the liraglutide clinical development programme were pooled to determine rates of major adverse cardiovascular events (MACE): cardiovascular death, myocardial(More)
BACKGROUND Coronary plaque classified as thin-cap fibroatheroma (TCFA) is believed to be associated with plaque rupture and coronary heart disease-related events. Although an association between duration of diabetes and increased coronary heart disease risk has been demonstrated, the relationship between TCFA and diabetes duration is unknown. METHODS AND(More)
CONTEXT Despite the widespread use of percutaneous coronary intervention (PCI), the appropriateness of these procedures in contemporary practice is unknown. OBJECTIVE To assess the appropriateness of PCI in the United States. DESIGN, SETTING, AND PATIENTS Multicenter, prospective study of patients within the National Cardiovascular Data Registry(More)
CONTEXT Bleeding complications with percutaneous coronary intervention (PCI) are associated with adverse patient outcomes. The association between the use of bleeding avoidance strategies and post-PCI bleeding as a function of a patient's preprocedural risk of bleeding is unknown. OBJECTIVE To describe the use of 2 bleeding avoidance strategies, vascular(More)
OBJECTIVE To determine the association of coronary artery calcification with hepatic steatosis in asymptomatic volunteers. PATIENTS AND METHODS The study group comprised 400 asymptomatic volunteers, enrolled from April 1, 2011, to September 30, 2012, without known coronary artery disease who were self-referred for screening noncontrast computed tomography(More)
OBJECTIVES The aim of this study was to describe contemporary frequency, predictors, and outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) in the United States. BACKGROUND CTO PCI can provide significant clinical benefits, yet there is limited information on its success and safety in unselected patient populations. (More)
Red cell distribution width (RDW), a measure of the variability in size of circulating erythrocytes, is an independent predictor of mortality in patients with cardiovascular disease. We hypothesized that RDW is a prognostic marker of death, myocardial infarction and unplanned revascularization in a broad population undergoing percutaneous coronary(More)
IMPORTANCE Patients with atrial fibrillation (AF) are at a proportionally higher risk of stroke based on accumulation of well-defined risk factors. OBJECTIVE To examine the extent to which prescription of an oral anticoagulant (OAC) in US cardiology practices increases as the number of stroke risk factors increases.
