Active clinical trials for "Infarction"

To test whether sleep-disordered breathing is associated with an increased risk of coronary heart disease, stroke, all-cause mortality, and hypertension. The multicenter, longitudinal study draws on existing, well-characterized, and established epidemiologic cohorts.

To investigate the relation between endogenous levels of estrogen in postmenopausal women and the subsequent development of coronary heart disease.

Coronary heart disease (CHD) is a serious health concern that affects millions of people in the United States. It is usually caused by atherosclerosis-a condition that occurs when fatty material and plaque build up on the walls of the arteries that supply blood and oxygen to the heart, causing the arteries to narrow. As the arteries narrow, blood flow to the heart can slow down or stop, which can cause chest pain, shortness of breath, heart attack, or heart failure. Another component of CHD events involves inflammatory changes that result in structural breakdown of atherosclerotic plaques. Adding niacin to statin medications may be an effective way to block inflammation in the atherosclerotic plaques. This study will examine magnetic resonance imaging (MRI) images and blood samples of participants in the AIM-HIGH study who are taking niacin plus statins or statins alone to determine the effect of these medications on inflammation in atherosclerotic plaques.

The main aim of this trial is to assess the long-term prognostic value of different types of Factor XIIa in an unselected, single center series of 871 chest pain patients admitted to the emergency unit, employing blood samples collected at admission. The second purpose of this study is to assess the incremental prognostic value of B-type natriuretic peptide (BNP) and high-sensitive C-reactive protein (hsCRP). A third purpose of this study is to evaluate the prognostic impact of the Omega-3 Index which is a measure of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) relative to other fatty acids in the erythrocyte membrane.

The purpose of this study is to compare clopidogrel effectiveness between severe hemodynamically unstable versus stable patients with acute myocardial infarction.

The purpose of the Study is to determine whether early treatment with pravastatin can reduce adverse cardiac events in patients with acute myocardial infarction and minimally to mildly elevated serum Low Density Lipoprotein -Cholesterol (LDL-C) levels.

While troponin is not detectable until several hours after an Acute Myocardial Infarction (AMI), copeptin is expected to be elevated very early after an AMI. A combination of both markers for the diagnosis of AMI early after the event is therefore expected to be advantageous.

Treatment of acute stroke is still difficult and the only specific drug approved (rtPA) can only be administered if treatment starts within 3 hours after onset of symptoms. This results in a still too small number of patients treated with rtPA ( < 15% in best clinical care institutions ). Ancrod is a differently acting biological drug which has been used for a long time but not for acute stroke treatment. STAT was the first RCT of medium size to show a significant benefit/risk ration if treatment starts within 3 hours. ESTAT was designed closely related to STAT but with a longer 6 hours window and specifically extended inclusion/exclusion criteria to avoid secondary complications possibly related to a longer time window.

To explore the role of insulin growth factor in cardiovascular disease in older men and women.

This proof-of-principle clinical trial at Mayo Clinic studies how patients and their physicians understand and utilize predictive genetic risk assessment. A critical goal of this clinical trial is to understand how individual patients and their doctors perceive and respond to genetic risk information that is largely uncertain.
