Filter by:The purpose of this study is to determine whether bivalirudin given during PCI is associated with better outcomes compared to un-fractionated heparin.
Mesenchymal stem cells from the bone marrow can be stimulated to differentiate into endothelial cells and participate in the development of new blood vessels in ischemic tissue. The aim of the study is in a phase I/II safety and efficacy study to evaluate the clinical effect of autologous mesenchymal stem cell therapy in patients with severe chronic myocardial ischemia.
Primary intracoronary stent placement after successfully crossing chronic total occlusions (CTO) decreases the high restenosis rate at long-term follow-up compared with conventional balloon angioplasty. Several studies have shown the efficacy of sirolimus-eluting stents in selected groups of patients. Whether sirolimus-eluting stents are superior to bare metal stents in CTO is unknown. In this prospective randomized trial, bare metal stent implantation will be compared with sirolimus-eluting stent implantation for the treatment of chronic total coronary occlusions. A total of 200 patients will be followed up for 6, 12, and 24 months with angiographic follow-up at 6 months. Quantitative coronary analysis will be performed by an independent core laboratory. The primary end point is the binary angiographic restenosis and reocclusion rate at 6 month follow-up.
Controversies still exists concerning the overall clinical effects of blood-based vs. crystalloid- based cardioplegic solution for myocardial protection during cardiac arrest. Both techniques are used world-wide. No larger prospectively randomized studies comparing the two methods have been reported. The aim of this study is to collect a large number of clinical data to create a proper basis for evaluation of the two techniques.
Clopidogrel (Plavix), a platelet ADP receptor antagonist, has become the standard of care to prevent thrombosis in interventional cardiology and is increasingly being used in unstable angina and NSTEMI. An increasing number of patients are referred to emergent or urgent CABG, and several studies, as well as our own experience, have shown that preoperative administration of irreversible platelets inhibitors increase the risk of bleeding complications following CABG.
Comparison study of myocardial perfusion SPECT imaging with current clinical use camera and new camera.
The purpose of this study is to determine the clinically meaningful definition and prevalence of aspirin resistance based on data linking aspirin-dependent laboratory tests to recurrent vascular events in cardiovascular patients taking aspirin.
This is an observational study among Latino patients who have coronary artery disease. The goal of the study is to determine the association between having depressive symptoms and the ability to modify one's health behavior. Specifically, participate in physical activity.
The purpose of this study is to compare two ways to treat patients with Type 2 Diabetes, Standard Care or Case-Managed Care. In-Patient Standard Care is guided by the assigned cardiologist and Out-Patient Standard Care by the existing diabetes care givers. Case-Managed care involves a consult with an endocrinologist and counseling from a diabetic educator and a dietician.
To evaluate the clinical safety, efficacy, and pharmacokinetics (PK) of the Endeavor Resolute Zotorolimus Eluting Coronary Stent System for the treatment of single de novo lesions in native coronary arteries with a reference vessel diameter (RVD) between 2.5 and 3.5 mm in diameter.
