Active clinical trials for "Heart Failure"

The purpose of this study is to characterize current management of patients with either heart failure or prior myocardial infarction and left ventricular dysfunction and to assess the effect of education, specific clinical guidelines, reminder systems, comprehensive disease state management tools, benchmarked quality reports, and academic detailing on the use of evidence-based heart failure therapies in cardiology practices. This study is a quality improvement initiative that is being conducted through review of patient records.

The primary objective of this study is to determine the utility of GRK2 to differentiate between normal patients and patient groups that differ by the presence/absence of HF symptoms, systolic or diastolic left ventricular dysfunction, and risk factors; and to evaluate if a new assay provides similar values as traditional methods for measuring GRK2 levels.

The purpose of this study is to determine whether extra education of patients with chronic heart failure can reduce 6 months readmission rate to hospital.

To investigate coronary heart disease and stroke among American men of Japanese ancestry who were living on the island of Oahu in 1965. Morbidity and mortality surveillance of the original cohort is continuing.

To provide a comprehensive analysis of risk factors for the development of clinical cardiotoxicities in over 6,000 children with cancer who had been treated on standardized protocols involving the use of anthracyclines alone or in combination with other potentially cardiotoxic therapies or with no use of anthracycline therapy.

To investigate trends in the incidence and survival rates of congestive heart failure (CHF) in two successive cohorts of elderly people (1970-74, 1990-94) in a health maintenance organization (HMO).

To examine the genetics of human susceptibility to Chagas' disease, a leading cause of heart disease throughout Latin America.

The Researchers are doing this study to find out if the cardiac rehabilitation program can improve measurements of frailty and improve independence, functional abilities, and feelings about health. Frailty can be measured by weakness (as measured by hand grip strength), slowness (as measured by walking speed), low level of physical activity, low energy or self-reported exhaustion, and unintentional weight loss.

The study tested the usefulness of cardiopulmonary exercise test (CPET) in selection of potential responders to CRT.

Improving physical activity is a core component of secondary prevention and cardiac (tele)rehabilitation. Commercially available activity trackers are frequently used to monitor and promote physical activity in cardiac patients. However studies on the validity of these devices in cardiac patients are scarce. The aim of this study is to determine the accuracy and responsiveness of two wrist-worn activity trackers, Fitbit Charge 2 (FC2) and Mio Slice (MS), for the assessment of energy expenditure (EE) in cardiac patients.
