Active clinical trials for "Coronary Artery Disease"

The main objective of this study is to assess the safety and effectiveness of the sirolimus-eluting Bx VELOCITYTM stent in reducing in-lesion restenosis in patients with de novo native coronary artery lesions.

The main objective of this study is to assess the safety and effectiveness of the sirolimus-eluting Bx VELOCITYTM stent in reducing in-lesion late loss in patients with de novo native coronary artery lesions.

The main objective of this study is to assess the effectiveness and safety of the CYPHER™ (CYPHER SELECT™) (Sirolimus-eluting) stent in reducing the occurrence of a composite endpoint of target vessel failure (TVF) in subjects treated for acute myocardial infarction as compared to a bare metal stent.

The purpose of this study is to determine whether the administration of omega-3 polyunsaturated fatty acids, particularly eicosapentaenoic acid (EPA), can be useful both to reduce coronary artery disease (CAD) risk and illness severity in clinically-stable patients with schizophrenia (or schizoaffective disorder), major depression or bipolar disorder (depressed phase) being treated with lipid lowering drugs (e.g., statins).

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.

The purpose of this study is to determine if treating periodontal infections (gum problems) will lead to fewer heart problems in patients at high risk for cardiovascular disease.

The overall purpose of this project is to improve the clinical outcomes of veterans with ischemic heart disease (IHD) through implementation of evidence-based lipid management, with a particular focus on veterans whose primary lipid abnormality is a low level of HDL-cholesterol (the �good� cholesterol).

Because blood pressure affects the heart, blood vessels, kidneys, and the entire body, it is important to keep it as normal as possible. There are several different ways to control blood pressure and to prevent or limit the development of heart disease due to high blood pressure. The purpose of this study is to compare two treatments to see how well they work and the difference in their side effects. One treatment includes the use of a calcium antagonist drug (Isoptin sustained release [SR] or Verapamil SR). The other treatment excludes the calcium antagonist and may include a non-calcium antagonist drug called a beta blocker (Tenormin or Atenolol). Both treatments may also include medication called angiotensin converting enzyme (ACE) inhibitors and water pills. None of the drugs in this study are experimental, they are all approved by the Food and Drug Administration (FDA).

INDICATION Microvascular angina. OBJECTIVES To investigate the effect of ACE (angiotensin converting enzyme) inhibition (quinapril) in improving coronary microvascular function. PATIENT POPULATION Women who meet the National Heart, Lung and Blood Institute-sponsored WISE (Women Ischemia Syndrome Evaluation) study criteria of chest discomfort, coronary flow reserve limitations and evidence for myocardial ischemia in the absence of significant coronary artery stenosis. STUDY DESIGN A prospective, randomized, placebo-controlled, comparative trial. TREATMENT Quinapril 80 mg/d versus placebo for four months. PRIMARY EFFICACY PARAMETER(S) Coronary flow reserve (CFR) at Week 16 adjusted for baseline CFR, treatment group assignment, site-specific variables, and site by treatment effects. SECONDARY EFFICACY PARAMETERS Week 16 change in chest discomfort as measured by the Seattle Angina Questionnaire adjusting for baseline values, site, and site by treatment effects. SAFETY PARAMETERS Hematology, blood chemistries, blood pressure and pulse, and frequency and occurrence of adverse events. STATISTICAL RATIONALE AND ANALYSIS A statistical rationale for the number of patients in the study has been provided. Interim analyses are planned after 15 patients have been enrolled in each group. ANTICIPATED TOTAL NUMBER OF PATIENTS 78 (39 per group). ANTICIPATED NUMBER OF PATIENTS AT EACH SITE Approximately 26

In Spain, family physician are currently recommended to prescribe an unsupervised walking program to their coronary heart disease (CHD) patients as a part of their cardiac rehabilitation program. However, there are a few family physicians who provide their CHD patients with supervised exercise (30 minutes of pedaling on an stationary bicycle at 60-85% of the peak heart rate (HR) attained at the maximal or symptom limited treadmill test, 3 times a week) at their primary care health centers, thinking that these patients improve their functional capacity, quality of life, and the control of cardiovascular risk factors, more than walking because they can not achieve the ideal exercise intensity for maximal benefits by walking. This study has been designed to investigate if CHD patients get more health benefits with the supervised exercise program at the health center than with the unsupervised walking program.
