BACKGROUND Multiple pathways contribute to accelerated coronary atherosclerosis in diabetics, including increased oxidative stress and inflammatory burden. Accordingly, the mechanisms of abnormal formation of reactive oxygen species and the changes in inflammatory gene expression were examined in diabetic coronary arteries. METHODS AND RESULTS In pigs(More)
OBJECTIVE This prospective randomized trial compared the Angio-Seal VIP with Perclose Proglide and to manual compression with respect to time to hemostasis and ambulation, patient satisfaction, and vascular complications following percutaneous coronary intervention (PCI). BACKGROUND The use of arterial closure devices for the reduction of vascular(More)
BACKGROUND Inflammatory mediators that originate in vascular and extravascular tissues promote coronary lesion formation. Adipose tissue may function as an endocrine organ that contributes to an inflammatory burden in patients at risk of cardiovascular complications. In this study, we sought to compare expression of inflammatory mediators in epicardial and(More)
Determinates of infarct size in patients with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI) have been incompletely characterized, in part because of the limited sample size of previous studies. Databases therefore were pooled from 4 contemporary trials of primary or rescue PCI (EMERALD, COOL-MI, AMIHOT, and ICE-IT),(More)
OBJECTIVES The purpose of this study was to compare the early and late results of percutaneous and surgical revascularization of left main coronary artery stenosis. BACKGROUND Unprotected left main coronary artery (ULMCA) stenting is being investigated as an alternative to bypass surgery. METHODS We randomly assigned 105 patients with ULMCA stenosis to(More)
The objective of this study was to evaluate the pharmacokinetic response to intravenous (IV) enoxaparin given 8-12 hr after subcutaneous (SC) dosing in patients undergoing percutaneous coronary intervention (PCI). Fifty-five patients received SC enoxaparin (1 mg/kg every 12 hr) followed by an IV bolus (0.3 mg/kg) 8-12 hr after the last SC dose, at the start(More)
OBJECTIVES The aim of the study was to evaluate early and late outcomes after percutaneous coronary intervention (PCI) of unprotected left main coronary artery disease (ULMCA) and to compare bare-metal stent (BMS) and drug-eluting stent (DES) subgroups. BACKGROUND PCI is an increasingly utilized method of revascularization in patients with ULMCA. (More)
UNLABELLED Surgical myocardial revascularization (CABG) in patients with unprotected left main coronary artery disease (ULMCA) is a Class I recommendation in the AHA/ACC guidelines, however it is associated with increased perioperative risk in non-ST elevation acute coronary syndromes (NSTE-ACS). The aim of this study was to compare early and late results(More)
Patients with acute coronary syndromes (ACS) may transition to percutaneous coronary intervention (PCI) after an initial phase of medical management that includes anticoagulation. When patients come to the catheterization laboratory, it is important to consider previously received anticoagulation. Enoxaparin has emerged as a more effective, yet simple,(More)
OBJECTIVES This study sought to determine whether hyperoxemic reperfusion with aqueous oxygen (AO) improves recovery of ventricular function after percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI). BACKGROUND Hyperbaric oxygen reduces myocardial injury and improves ventricular function when administered during(More)
