Active clinical trials for "Heart Failure"

The purpose of the study is to determine if the combination of AVJ ablation followed by BiV pacing significantly improves functional status and exercise capacity compared to pharmacologic rate control in patients with chronic AF and depressed ejection fraction, regardless of rate or QRS duration.

This is a randomized, double-blind, placebo-controlled, multi-center, sequential cohort study in subjects with congestive heart failure (CHF) and impaired renal function who are on stable furosemide treatment (³ 40 mg daily). A total of 50 subjects will be randomized to each increasing dose level of SLV320 or placebo in a sequential fashion.

Prospective, multi-center, post-market, non-randomized, nested-control, observational study of the CE marked CardioKinetix Parachute Implant System.

The main objective is to evaluate the pronostic value of endothelial dysfonction in acute heart failure on a combined criteria associating cardiovascular mortality, nex hospitalisation for decompensated heart failure, cardiac graft or ventricular assistance 2 month and 1 year before acute heart failure.

This study will assess the reliability of POC ultrasound in estimating right and left atrium pressures in patients with acute decompensated heart failure. This study will compare hemodynamic measurements obtained from pulmonary artery catheters with those estimated from POC ultrasound using inferior vena cava (IVC) measurements and the presence of atrial septal bulge.

The purpose of this sub-study is to use positron emission tomography and computed tomography imaging (PET/CT) with an investigational drug called [11C] acetate to see if inflammation in patients with acute decompensated heart failure (ADHF) can cause changes in blood flow and oxygen use in the heart. This study may help physicians better understand how to treat patients diagnosed with ADHF in the future.

The purpose of the BIO-AffectDX Study is to prospectively evaluate improvement from baseline in heart failure subjects with atrial fibrillation (AF) implanted with a two-lead CRT-DX system, with emphasis on a comparison of patient outcomes between AF subtypes.

Pulmonary arterial hypertension(PAH) is associated with the development of right heart failure. In the setting of heart failure, the heart shifts to increasing dependence on glucose metabolism. In this study, the investigators will perform cardiac positron emission tomography/magnetic resonance imaging (PET/MRI) scans to measure glucose metabolism in the heart before and after initiation of pulmonary vasodilator therapy for pulmonary arterial hypertension.

The purpose of the Heart Failure and Risk of re-Admissions Determined by Abnormal REVEAL Parameters (HF RADAR) study is to evaluate the ability of cardiac rhythm (Cardiac Compass) data to predict future cardiac events in heart failure (HF) patients recently discharged after a hospitalization for heart failure who have or plan to have a implanted loop recorder (ILR), specifically, the Reveal XT device. The study will enroll 40 HF patients (with LV function ≥ 40%) admitted to an acute care facility (observation status or hospital stay) for heart failure who either have a Reveal XT device in place or plan to have the ILR device inserted for clinical indication within 14 days of discharge from the hospitalization. HF patients will be followed for 6 months. Device date will be captured during normal clinic visits and at 6 months.

In Switzerland 15% of discharged patients are readmitted within 30 days. Acute heart failure is the leading cause of hospital admission and one of the most frequent reasons for re-admission, mainly because of congestion-driven symptoms. Residual congestion is noted in 10%-15% of patients at discharge and is associated with an increased risk of re-admission and mortality. Lung ultrasound outperforms both chest X-ray and physical examination in detection of lung congestion. Several semiquantitative scanning protocols exist for quantifying congestion. The aim of this study is to compare for the first time two widely used lung ultrasound protocols, one exhaustive (28-points) and one simplified (8-points), in real-time settings. The focus is placed on reproducibility (expert-beginner interobserver concordance), feasibility (time consumption for images acquisition and interpretation) and performance (detection of B-lines clearing) of both scores. Semi-quantitative method is expected to have better feasibility with similar reproducibility and performance.
