Active clinical trials for "Heart Diseases"

Patients with CAD and diabetes mellitus have a better prognosis than patients with CAD and no diabetes mellitus. In acute coronary syndrome patients with an insulin therapy had a better survival than patients with oral antidiabetics. But there is not known wether perioperative therapy with insulin or oral antidiabetics is associated with higher risk for higher perioperative cardiac morbidity and mortality and worse long-term survival.

Myocardial scintigraphy with 123I-MIBG allows for visual and semi-quantitative assessment of sympathetic cardiac innervation using the hear to mediastinum ratio (HMR). Impaired cardiac MIBG clearance may occur in patients with congestive heart failure (CHF). The purpose of present study was to develop and validate a quantitative index for the assessment of cardiac MIBG uptake kinetics using SPECT/CT for diagnosis of CHF

Patients who have iron overload due to chronic blood transfusions and have developed heart failure or who are at high risk of heart failure because of the high levels of iron in their hearts, will be treated with deferiprone, an investigational drug, in combination with deferoxamine (Desferal). Some studies suggest that deferiprone may be better than deferoxamine in removing iron from the heart and improving heart function, and that using both drugs together may remove more iron. Participants would make a clinic visit for lab studies each week, and would continue to take deferiprone for as long as their physician feels it is useful in their care.

Heart disease and stroke disproportionately affect African Americans in the United States. These conditions are likely caused by both environmental and genetic factors. This study will attempt to identify specific genes of African and European ancestral origins that may influence the development of heart disease in African Americans.

To understand how depression leads to congestive heart failure (CHF) in older adults.

The purpose of this study is to determine whether the SF-36 can be administered reliably to cardiac surgery patients (two to three days) post-surgery, with the patient answering the questions of this survey from a pre-surgical perspective.

To scan the genome for obesity in a multi-ethnic sample.

To explore the associations between cognitive functioning and three major cardiovascular disease risk factors: high blood pressure; high total plasma homocysteine (tHcy); and ApoE e4 genotype.

To investigate the role of endothelial dysfunction and increased vascular stiffness as contributors to the pathogenesis of cardiovascular disease.

To test the hypothesis that the responsiveness of major and emerging cardiovascular disease risk factors to changes in diet composition clusters within families depending on genetic susceptibility factors.
