Active clinical trials for "Myocardial Ischemia"

Unprotected left main coronary artery (ULMCA) stenting, offering restoration of a native flow to left coronary artery, is the subject of intense investigations as a potential alternative to bypass surgery. The purpose of the study is to compare the short and long term results of unprotected left main stenting with coronary artery bypass surgery.

A growing body of evidence links Chlamydia pneumoniae to the progression of coronary heart disease. The purpose of this study is to determine the positive and negative effect of 14 days treatment with clarithromycin 500 mg daily in patients already suffering from stable coronary heart disease. The participants will be followed for at least two years after the treatment. Abbott Laboratories supplied Clarithromycin and placebo tablets.

The purpose of this study is to investigate additional cholesterol lowering effects in patients with coronary heart disease by giving an investigational drug with a patient's current approved cholesterol lowering medication.

The objective of study is to compare the anti-ischemic efficacy and safety profiles of once daily amlodipine or isosorbide-5-mononitrate in the treatment of stable asymptomatic and symptomatic myocardial ischemia

Data from VA-funded studies and the broader literature indicate that chronic stable angina (CSA) is prevalent, under recognized, under treated and associated with reduced quality of life. There are substantial opportunities for improving care of patients with this debilitating and potentially fatal problem. Because primary care providers manage most patients with CSA, efforts to improve care must necessarily involve the primary care delivery system. C3P is composed of a set of interventions employing a Collaborative Care Team model, which has been shown to be effective in managing other chronic illnesses in the primary care setting.

The primary objective of this study is to assess whether adding modified-release dipyridamole to aspirin (Asasantin Retard) has measurable effects on markers of platelet function (for example, platelet aggregation) in patients with cardiovascular disease who are known to be resistant to aspirin alone

The ABSORB EXTEND trial is to continue the assessment of the safety and performance of the ABSORB Bioresorbable Vascular Scaffold (BVS) System ABSORB BVS is currently in development at Abbott Vascular.

Surgery for blocked arteries in the heart (coronary artery bypass grafting) can be accomplished using veins from the leg sewn onto the heart to provide an alternate path for blood flow, i.e. 'bypassing' the blockages. These veins themselves can block over time. This may result in part simply from the trauma from the surgery, in other words, by removing the vein from the leg and then sewing it to the heart. Another mechanism may be the abnormal metabolic processes within the body responsible for the plaque build-up of the heart arteries in the first place - this may lead to the blockages of the veins used for bypass. In the present era of heart bypass surgery, this incidence of veins blocking remains high despite advances in blood thinners and cholesterol medications. This study is designed to determine whether two new interventions may potentially reduce the incidence of blockages in the veins used for heart bypass surgery. One is a surgical technique significantly reducing the trauma associated with removing the leg vein prior to use as a bypass graft onto the heart. The second intervention is the use of a nutritional supplement before and after surgery which is composed of fish oils. The study will recruit sufficient patients to provide strong and relevant conclusions regarding both study questions. It will be highly applicable also because it will include approximately 1,550 patients from approximately 50 hospitals across many countries. We believe these techniques will result in significantly less vein blockages in patients one year after heart bypass surgery.

The purpose of this study is to see if 40 mg of rosuvastatin taken daily will reduce the atherosclerosis (fatty deposits) in your arteries

To investigate the effect of different dosages of aspirin on platelet aggregation and to determine the possible mechanisms of aspirin resistance, we intend to compare the effects of low, medium dose aspirin with clopidogrel (an alternative antiplatelet agent) in patients after coronary artery bypass surgery.
