Filter by:Rationale: Patients with severe ventricular dysfunction and coronary disease have high morbidity and mortality. They may benefit from revascularization, but have significant peri-operative morbidity and mortality. Positron emission tomography (PET) imaging with F-18-fluorodeoxyglucose (FDG) can detect viable myocardium that may recover from revascularization in such patients. It is unclear whether use of FDG PET in this population is improves outcome or is cost-effective. Objectives: The principal aim is to determine whether FDG PET-guided therapy is effective versus standard care. Secondary objectives are to determine whether FDG PET-guided therapy improves LV function, quality of life and is good value for money versus standard care.
To study the effect of red wine, beer and fruit juice on endothelial function in patients with coronary Heart disease.
The main objective of this study is to assess the safety and effectiveness of the sirolimus-coated Bx VELOCITY™ stent in maintaining minimum lumen diameter in de novo native coronary artery lesions as compared to the uncoated Bx VELOCITY™ balloon-expandable stent. Both stents are mounted on the Raptor® Stent Delivery Systems. The secondary objective is to assess cost-effectiveness expressed in incremental cost/life year gained or cost/quality adjusted life year gained at different time points (8 months, 1 year, 3 and 5 years).
The study is designed to determine whether a dual isotope protocol is equivalent to a single isotope in the diagnosis of myocardial ischemia and infarction using MYOVIEW SPECT imaging.
This study offers catheter-based treatment of heart or artery disease. This protocol permits treatment of patients with cardiovascular diseases who may not be eligible to participate in current research protocols. The treatment offered in this protocol is not experimental, but rather standard treatment provided in most large referral hospitals in the United States. Patients 18 years of age and older who are candidates for catheter-based treatment of obstructive artery disease, including blocked blood flow in a coronary artery (artery to the heart) or in an artery of the arm, leg, brain or kidney may be eligible for this study. Candidates are screened with a general medical evaluation that may include blood tests, magnetic resonance imaging, and monitoring of heart rate and rhythm. Participants undergo angioplasty or stenting for blockage in an artery to the heart or an artery of the arm, leg, brain or kidney. The procedure uses a balloon-tipped catheter to open the blocked artery and likely requires permanent implantation of a metal tube (stent) to improve blood flow through the vessel. During the procedure, the patient is given a sedative and pain medication, if needed.
The purpose of this study is to determine whether a particular substance involved in inflammation, called leukotrienes, is involved in causing heart disease to occur or to progress.
AIR STUDY TITLE: Anti-Ischemic effects of Abciximab(Reopro) PATIENT POPULATION: Patients undergoing PCI(an interventional procedure placing a small stent/metallic tube to keep a narrowed artery in your heart open) and either on a stable statin dose or not on a statin. Statin= cholesterol lowering drug(ie, lipitor, zocor). INTERVENTION: Heparin vs. heparin + abciximab during PCI PURPOSE: Measure the effects of abciximab on special healing blood stem cells (EPC's-Endothelial Progenitor Cells), on inflammation, on oxidative stress and on microvascular blood flow. PATIENT ASSESSMENT: 1. 50ccs blood draw on day 1(from sheath), day 2 ,day 7 and day 28. 2. Measurement of blood flow in selected suitable patients 3. 10 minute questionnaire before discharge and on visit on day 28.
Cardiovascular disease (CVD) is one of the leading causes of death in the United States. Currently, there is little information about the lifetime risk of CVD among non-white ethnic groups. This study will analyze data from participants in several ongoing clinical studies to identify the lifetime risk for CVD among various ethnicities.
How to use drug eluting stents (DES) in bifurcation lesions. A strategy of routine stenting of both main vessel and side branch versus a strategy of routine main vessel stenting and optional treatment of side branch. A randomized Nordic multicenter study including 400 patients with angina pectoris with clinical angiographic follow-up.
The purpose of this study is to determine which of these anti-clotting medications, abciximab plus unfractionated heparin or bivalirudin, is more effective to prevent thrombotic and bleeding complications in patients suffering from a heart attack and undergoing coronary intervention.
