Filter by:We are studying the affect of caffeine on the sensitivity of detecting coronary artery disease (blockages in the blood flow to the heart) with adenosine tracer scans. Adenosine is a drug used routinely in patients to relax heart blood vessels in order to assess for the presence of coronary artery disease. Often, if patients have had caffeine, the adenosine scan is not used because of the belief that caffeine may reduce the ability to detect coronary artery disease. We would like to test whether caffeine affects our ability to detect coronary artery disease with adenosine tracer scanning. We will perform an imaging study of the heart with adenosine after you have received caffeine.
This is a multicenter, randomized, parallel group, placebo controlled study designed to evaluate the efficacy, safety, and tolerability of ezetimibe added to ongoing atorvastatin therapy compared with ongoing atorvastatin treatment alone. This study will involve subjects with primary hypercholesterolemia and coronary heart disease (CHD) who are currently being treated with atorvastatin and who would benefit from additional reduction in low-density lipoprotein cholesterol (LDL-C).
The aim of this study is to determine in high risk diabetics if the positive predictive value of stress echocardiography is superior to the positive predictive value of stress scintigraphy in the diagnosis of coronary stenosis > 50%.
The study investigated if aerobic endurance exercise of different intensity has different impact on the physical capacity and myocardial function in patients with coronary artery disease. Patients with stable CAD trained for 10 weeks, and oxygen consumption and myocardial function were measured before and after this period. Patients were randomly assigned to each exercise group.
The purpose of this study is to test a measurement tool and a new training intervention for problem solving in self-management of high cardiovascular disease (CVD) risk in African Americans with type 2 diabetes.
The purpose of this study is to compare the 2-year cardiac outcomes for women with limited exercise capability based on the resuls of either pharmacological stress myocardial perfusion imaging or a combined protocol that incorporates both exercise and pharmacological stress. The goal of the study is to compare these two methods for patient tolerability, safety and prognostic value
Postoperative new-onset atrial fibrillation (AF) is the most common complication stemming from coronary artery bypass graft surgery, and is associated with increased early and late mortality risk. Standard guidelines recommend β blockers for the prevention of AF; however, no prospective study has compared the relative efficacy of β-blocking agents. We hypothesize that carvedilol, a non-selective adrenergic blocker with both anti-inflammatory and antioxidant properties, is more effective than metoprolol, a conventional β1-selective antagonist, in suppressing new-onset AF following off-pump coronary bypass surgery. We have designed the Carvedilol or Metoprolol Post-Revascularization Atrial Fibrillation Controlled Trial (COMPACT) to test our hypothesis in a multi-center, open-label, and randomized controlled trial.
The ASPECT study is an Asian multicenter, randomized, controlled, triple-blinded study designed to evaluate the ability of the Cook Incorporated Paclitaxel Eluting Supra G Coronary Stent to reduce restenosis in the coronary artery.
The purpose of this study is to evaluate the clinical and angiographic outcome of implantation of stents eluting or not eluting Sirolimus in patients with complex coronary artery lesions suitable for percutaneous coronary intervention.
The purpose of this study is to evaluate the clinical, echocardiographic and angiographic outcome of distal protection in the infarct related coronary artery and implantation of drug eluting versus bare metal stents in patients with ST-elevation myocardial infarctions treated acutely with percutaneous coronary intervention.
