Active clinical trials for "Heart Diseases"

To examine clinical cardiovascular outcomes of African Americans.

To develop an epidemiologic model to estimate the benefits, costs and risks of disease prevention in the elderly.

To design Computer Aided Telephone Interviewing (CATI) software tools for survey research.

To determine the nature, extent and molecular mechanisms responsible for impaired fibrinolysis in White, Black, Hispanic and American Indian populations with respect to the presence or absence of diabetes. The overall objective is to determine whether impairments of fibrinolysis underlie subclinical and clinical vascular disease in diabetes in specific populations with and without accelerated microvascular disease.

To identify the role of salt-sensitivity of blood pressure in the pathogenesis of hypertension.

To conduct a pooled analysis of NHANES I/II data on race, gender, and coronary heart disease.

The aim of this research is to apply cardiac tissue characterization in order to assess left ventricular function in cardiac surgical patients pre and post cardiopulmonary bypass. The procedures to be used include a retrospective review of transesophageal images obtained during conventional intraoperative transesophageal echocardiography (TEE) for cardiac surgery, as well as a secondary analysis with Tissue Doppler. The results will be compared with hemodynamic data obtained from a pulmonary artery catheter (PAC).

The purpose of the FIT-O study was to estimate the prevalence of having a caregiver (paid and/or informal) among hospitalized cardiac patients by demographic factors such as patient age and race/ethnicity, and to link caregiver status to clinical outcomes following hospitalization. A secondary aim was to collect anonymous family tree data to provide an estimate of the number of first degree family members, their basic demographics, and the distance at which they live from the medical center.

The cardiac output (CO) is an important parameter in the diagnosis and therapy of cardiac diseases. The current standard methods for the determination of the CO, however, are either invasive (e.g. right heart catheterization) or technically expendable and expensive (magnetic resonance tomography, MRT). Therefore the aim of the study at hand was to evaluate the electrical velocimetry technique as a new method for determining the CO and to compare this new technique with the Inert Gas Rebreathing Method and with the Magnetic Resonance Tomography

The PREDICT study is to develop and validate a diagnostic blood ASGES (age, sex, gene expression score) or Corus CAD for atherosclerotic coronary artery disease (CAD). The Corus CAD (Age/Sex/Gene Expression score - ASGES) will use quantitative real-time PCR (RT-PCR) to quantify the expression of multiple genes from circulating peripheral blood cells to assess the presence of clinically significant CAD in a patient.
