Active clinical trials for "Myocardial Ischemia"

To assess long-term effects of a strict lifestyle change program on lipids, blood pressure, myocardial perfusion, and coronary atherosclerosis.

To determine for a group of men at high risk of death from coronary heart disease whether a special intervention program to lower serum cholesterol, reduce blood pressure, and eliminate cigarette smoking would result in a significant reduction in mortality from coronary heart disease.

To determine whether the daily administration of 1 gm of aspirin to individuals with a documented myocardial infarction would result in a significant reduction in mortality over a three year period.

To determine whether the regular administration of the beta-blocker drug propranolol to people who had had at least one documented myocardial infarction would result in a significant reduction of mortality from all causes over the follow-up period. Eligible volunteer patients were recruited to participate in a double-blind clinical trial within 21 days after the onset of the acute event. One-half of the patients were randomly assigned to a beta-blocking drug (propranolol) and one-half to a placebo. The trial also evaluated the effect of propranolol on incidences of coronary heart disease mortality, sudden cardiac death, and nonfatal myocardial infarction plus coronary heart disease mortality in persons with documented previous myocardial infarction.

To assess the effect on cardiovascular mortality of alternate-day consumption of 325 milligrams of aspirin and, secondarily, the effect on cancer incidence of alternate-day consumption of 50 milligrams of beta-carotene.

The diagnostic efficacy and safety of the XTR004 myocardial perfusion PET imaging tracer are evaluated for known or suspected CAD with the use of invasive coronary angiography as the reference standard for the diagnosis of CAD and invasive pressure-temperature FFR/IMR as a reference for the detection of abnormal coronary function.

stress cMRI with Dobutamine stress agent (stress cMRI), represent the combination of two orders of exams routinely performed (cMRI and stress diagnostic series of exams) without additional risk for the patient, but with the advantage of non-invasiveness and lack of radiation, and less laborious for the participants

This study will assess the safety and tolerability of the investigational radiolabeled imaging agent technetium-99m-labeled ethylenedicysteine-deoxyglucose (99mTc-EC-DG). Additionally, the study will determine the specific times to best image the heart using a SPECT camera with the investigational imaging agent and compare the images to those taken while undergoing the standard rest and exercise/regadenoson testing previously performed to detect the presence and severity of Coronary Artery Disease (CAD).

The purpose of this study is to investigate prevalence of abdominal aortic aneurysms (AAA) among male patients with coronary artery disease (CAD). Secondary purpose is to document cost-effectiveness of ultrasound screening of AAA in selected population. Ethiology of AAA is known to be common with atherosclerotic arterial diseases, and on the basis of our previous studies (ClinicalTrials.gov ID CAD-AAA-02) the prevalence of AAA seems to be higher in CAD population than unselected male population. This leads to hypothesis that selective screening of these patients (for AAA) could be cost-efficient and life saving option for detecting AAAs before rupture. Study will be carried out as a single-center prospective screening study. Patients will be selected for this study on basis of their ICD 10 diagnose codes in North Carelian patient information system. Inclusion criteria will be any kind of atherosclerotic heart disease (ICD10 codes I20-I25). Criteria for exclusion are malignant disease, already diagnosed or treated AAA and failure to give informed consent. 800 patient records that meet the inclusion criteria will be reviewed for eligibility. Invitations for screening will be sent for 600 patients with intention to have at least 400 patients screened. Screening will be done by verified sonographers in designated screening appointments.

This study will evaluate the effect of GS-6615 in adults with chronic stable angina and coronary artery disease (CAD) receiving a stable daily dose of up to 2 antianginal medications. The study will consist of two periods: a 1 to 3 week Qualifying Period and a Treatment Period lasting 13 days (± 3 days). During the Qualifying Period and at the end of the Treatment Period, participants will undergo exercise tolerance testing.
