Active clinical trials for "Heart Failure"

The purpose of the study is to characterize atrial arrhythmias in patients indicated for Cardiac Resynchronization Therapy (CRT) and to monitor changes in atrial arrhythmias while CRT is provided.

To assess the impact of a multidisciplinary treatment program on three-month readmission-free survival in elderly congestive heart failure patients.

This study aims at identifying processes that are deregulated in blood cells by Clonal Hematopoiesis of Indeterminate Potential (CHIP) which are involved in the development of heart failure with preserved ejection fraction (HEpEF).

The purpose of this study is to evaluate the impact of using hand carried ultrasound measurements of volume status in directing treatment of heart failure patients admitted with acute exacerbation.

The primary objective of this study is to provide access to omecamtiv mecarbil for participants who have completed GALACTIC-HF 20110203.

To translate the Minnesota Living with Heart Failure Questionnaire (MLHFQ) questionnaire into Urdu language of Pakistan. To determine the validity and reliability of cross cultural adapted and Urdu translated MLHFQ questionnaire version among HF patients.

This trial will compare two management strategies for HF patients with preserved LV function in sinus rhythm and LBBB. The control group will be treated with practice guideline optimal medical therapy for HF. The experimental group will be treated with CRT in addition to optimal medical therapy for HF. In addition, the trial will further compare two methods of delivering CRT. One experimental group will receive BiV-CRT, while the second experimental group will receive CS-CRT.

Background: Treatment of heart failure has improved considerably in the past decades. Despite this improvement, the disease may progress into an end-stage ultimately leaving the physicians with no other treatment option than heart transplantation (HTx). There are multiple etiologies underlying heart failure. Cardiomyopathy is the leading cause for HTx in any age-group with coronary artery disease being the second most common cause in adult patients. Alterations in the mitochondrial function have been recognized as key factors in heart failure. During the transplant procedure the diseased heart is removed, providing a unique opportunity to collect samples eligible for thorough mitochondrial examination. Hopefully, the knowledge gained from this investigation will contribute with important insights in the diseased myocardial energy metabolism. Such knowledge may pave the way for development of treatments targeting both energy substrate supply for adenosine-triphosphate generation produced by the mitochondria as well as mitochondrial function in the failing heart. Hypothesis: The pathological myocardial function seen in heart failure is related to dysfunctional cardiac mitochondria Objective: To examine if cardiac mitochondrial function in end-stage heart failure of multiple etiologies is inferior to mitochondrial function in transplanted hearts with no signs of rejection or vasculopathy. Design: Myocardial mitochondrial function analyzed from 24 explanted hearts will be compared to endomyocardial biopsies from 20 HTx patients at scheduled biopsies (1 or 2 years after implantation).

The aim of this study is to determine whether heart failure patients can tolerate a four-weeks of a new exercise training regimen that targets peripheral tissues (Regional Specific Training Stimulus-RSTS) and has been show to produce significant benefits in aerobic capacity and strength in healthy subjects aged 70+years who were at risk for losing functional independence.

Empirical implantation of the left ventricular lead is the prevailing practice in cardiac resynchronization therapy device implantation. The response rate to the therapy has been uniformly 70% only despite various methods to screen patients before device implantation. This study tested the hypothesis that echocardiography to assess acute resynchronization of the left ventricle during device implantation may improve the response rate to the therapy.
