RECRUITING

NCT05677100

Diuretics Alone vs. Aortix Endovascular Device for Acute Heart Failure

Aortix is a circulatory support device for chronic heart failure patients on medical management who have been hospitalized for acute decompensated heart failure (ADHF) and have persistent congestion despite usual medical therapy. Eligible ADHF patients with diuretic resistance (irrespective of ejection fraction) will be enrolled and randomized 1:1 to either the Aortix system or standard of care medical management.

Magnetic Resonance Spectroscopy Studies of Cardiac Muscle Metabolism

The metabolism of the heart provides the chemical energy needed to fuel ongoing normal heart contraction. Magnetic resonance spectroscopy is a technique used in a MRI scanner that can be used to measure and study heart metabolism directly but without blood sampling or obtaining tissue biopsies. One of the hypotheses this study aims to investigate is whether energy metabolism is reduced in heart failure and whether that contributes to the poor heart function.

Cardiovascular Health Study (CHS)

To determine the extent to which known risk factors predict coronary heart disease and stroke in the elderly, to assess the precipitants of coronary heart disease and stroke in the elderly, and to identify the predictors of mortality and functional impairments in clinical coronary disease or stroke.

Prospective Observational Study of the ICD in Sudden Cardiac Death Prevention

The overall hypothesis of this study is that subtle interactions between structural (substrate) and functional (trigger) abnormalities of the heart, some of which are genetically-determined, can be used to identify patients at high risk of sudden cardiac death (SCD). Such information may be used to better define patients most likely to benefit from replacement of an internal defibrillator (ICD). The prospective, observational study to enroll, categorize and follow patients who receive an ICD pulse generator replacement for primary prevention of SCD (PROSe-ICD) was established to : 1. to gain a better understanding of the biological mechanisms that predispose to SCD 2. to develop readily determined clinical, electrocardiographic, genetic and blood protein markers identify patients with an increased risk of dying suddenly

Diuretics vs. Afterload Reduction for Treatment of HeartLogic Alerts

The DART-HA study is a single-center, open label, trial intended to evaluate the clinical efficacy of standard treatment options for congestive heart failure (observation, diuretic or afterload reduction therapy) in patients without new symptoms who have developed abnormalities of the HeartLogic heart failure diagnostic feature.
