Active clinical trials for "Myocardial Ischemia"

The purpose of this study is to demonstrate that Iodixanol 320 is associated with a lower incidence of contrast-induced nephropathy (CIN) when compared with hyperosmolar contrast medium Iomeprol 350 in patients with impaired renal function undergoing percutaneous coronary interventions (PCI).

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.

The main objective is to observe the effects of erythropoietin administration on different blood markers of ischaemic cardiac lesions induced by cardiopulmonary bypass.

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.

To test a practical, theory-based intervention to achieve long-term behavior change for postmenopausal women with Type 2 diabetes at high risk for developing coronary heart disease (CHD).

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.

The KYOTO HEART Study is to assess the add-on effect of valsartan, an Angiotensin-Receptor Blocker, on top of the conventional treatment in high risk patients in Japan with hypertension in terms of the morbidity and mortality.

The purpose of this study is to determine which of two treatments, Warfarin or aspirin, is better for preventing death and stroke in patients with poor heart function. We are now transitioning into the sub-analysis part of the WARCEF patient data. The study has recently completed data analysis for its Primary Aim. All randomized patients have completed their follow up. All study related procedure as per the protocol has been completed. We are now in the extension phase of the study to obtain more patient data to address further aims of the study. No new procedures are performed and data already in place at the sites will be collected (EKG and echocardiograms). The aims for this study extension are: To assess progression of cardiac dysfunction over time among heart failure patients To correlate prognosis with cardiac dysfunction

To determine if supplements of vitamin C, vitamin E, beta-carotene, and B-vitamins (a combination of folic acid, vitamins B6 and B12) reduce risk of major cardiovascular events in high risk women with a prior history of atherosclerotic cardiovascular disease. The trial is a companion to the Women's Health Study (WHS), a primary prevention trial of vitamin E and aspirin in a low risk population of women.

To determine if estrogen replacement therapy, with or without low dose progesterone, slows progression or induces regression of coronary atherosclerosis in postmenopausal women.
