Active clinical trials for "Myocardial Ischemia"

Coronary artery bypass surgery is associated with postoperative cognitive decline, which has largely been attributed to the use of the heart lung machine. We hypothesized that long-term cognitive outcome may improve by avoiding the heart lung machine. The objective of the present study is to compare the effect of coronary bypass surgery with and without heart lung machine on cognitive and clinical outcome, five years after surgery.

The purpose of this study is to determine whether the combination of clopidogrel with aspirin prevents the development of blockages (atherosclerosis) in vein grafts one year after coronary artery bypass surgery (CABG) compared to aspirin alone.

Influenza vaccine reduces the cardiovascular events in post-myocardial infarction (MI) patients and in those with stable angina (SA).

This study wishes to understand: whether vaccination against influenza in coronary artery disease (myocardial infarction and stable angina) patients is as effective as it is in healthy subjects; whether vaccination really decreases the episodes of influenza infection in those coronary artery disease patients who receive the vaccine than those who do not.

Our research aims to improve the use of medicines known to prevent recurrent heart attacks. In particular, we know that statin treatment is useful after heart attacks, but many patients do not use it. There are a few possible reasons for this. Patients cannot find affordable medicine. Their doctor may not prescribe the medicine after they leave the hospital. Some people may culturally mistrust using the medicine. So they may decide not to take it even if it is prescribed. We are developing a hospital based culturally attuned program to target this problem. In this program, a community health worker counsels and helps patients in accessing pharmacy assistance programs. We will test whether this program can improve appropriate statin use. We will enroll patients who have heart attacks. We will compare patients who are counseled by the community health worker with those who get the usual care at baseline and at 6 and 12 months (participants enrolled during the early phase of the recruitment will have an additional study visit at 24 months). We will test if their "bad" cholesterol levels are controlled. We will find out how regularly they have filled their questionnaire and taken the medicine. Finally, we will test if they are getting benefit from the statin treatment. We will do this using blood tests and imaging the patients' arteries with ultrasound. We will also measure how cost-effective it is for a hospital to run the program. It is our goal to develop a community health worker model that is culturally sensitive for people with cultural, educational or educational barriers. Statin use is known to benefit patients in theory; such a culturally competent program will improve health outcomes in practice. After we test it, a cost-effective program such as this can be implemented in other hospitals.

The purpose of this study is to assess whether nesiritide compared to placebo when given with standard of care therapies, helps preserve kidney function in heart failure (HF) patients undergoing heart bypass graft surgery that requires the use of a cardiopulmonary bypass machine (CPB pump or heart-lung machine).

The study will be conducted at up to 25 U.S. centers and will be a double-blind randomized parallel group placebo controlled study among subjects with stable coronary artery disease (CAD). Subjects will be randomized to receive either placebo tablets or one of 2 orally active doses of A-002. The duration of study drug therapy will be 8 weeks.

The study will be conducted at up to 80 centers worldwide and will be a double-blind randomized parallel group placebo controlled study among subjects with stable coronary artery disease (CAD). Subjects will be randomized to receive either placebo tablets or one of 4 orally active doses of A-002. The duration of study drug therapy will be 8 weeks.

The study will evaluate the effect of familial risk assessment and prevention prompts tailored to familial risk on health behaviors and use of preventive services among adults who are members of primary care practices in the U.S.

There is growing evidence that antiretroviral therapy (ART) increases the risk of coronary heart disease (CHD) through metabolic side effects, such as dyslipidemia, insulin resistance, and type II diabetes. Prevalence of risk factors for CHD in HIV-infected individuals receiving ART in the Swiss HIV Cohort Study (SHCS) is high. This cluster randomised controlled trial is nested into the SHCS and will investigate whether physicians randomised to the routine provision of risk profiles from their patients receiving ART will improve the management of risk factors in HIV-infected patients compared to control physicians not routinely receiving such information. Risk profiles will be generated by the SHCS data center and provided to clinicians in all study centers.
