Active clinical trials for "Heart Failure"

This study aims to compare effects of inspiratory muscle training added by aerobic training to aerobic training alone in heart failure patients with inspiratory muscle weakness. To do so, strength and endurance of inspiratory muscles, functional capacity, quality of life, heart rate variability and sleep apnea evaluations will be conducted in patients with heart failure.

The scope of the USE-BNP Trial is to investigate whether knowledge of BNP measurements, in conjunction with clinical assessment, in the outpatient setting can guide the management of therapy in patients with heart failure.

The purpose of this study is to evaluate changes in left ventricular mass and cardiac function in patients with active acromegaly before and after treatment with the growth hormone receptor antagonist pegvisomant for one year.

Background: Patients with congestive heart failure (CHF) show muscle mass wasting and decreased testosterone levels. Long-term testosterone supplementation improves walking distance and glucose metabolism of patients CHF. No studies have investigated the integrated effects of testosterone on exercise oxygen uptake muscle strength and glucose metabolism in patients with CHF regardless of the presence of hypogonadism. Aim: To assess the effect of a 12 week testosterone administration on maximal exercise capacity, muscle strength and insulin resistance in elderly CHF patients. Methods: Seventy elderly patients with stable CHF, mean age 71 ± 8 years, ejection fraction 34 ± 1%, NYHA class II/III 38/32, were enrolled. Of these, 35 were randomized to receive testosterone therapy (through intramuscular injection every 6 week) and 35 to receive placebo both on top of maximal medical therapy. At baseline and after 12 weeks all patients underwent echocardiogram, cardiopulmonary test, 6-minute walking test (6MWT), quadriceps maximal isometric and isokinetic strength.

Cardiac resynchronization therapy (CRT) is used to treat dilated heart failure with discoordinate contraction. Dyssynchrony typically stems from electrical delay leading to mechanical delay between the septal and lateral walls. Right ventricular apical pacing might be associated with long-term adverse effects on left ventricular function, and alternative pacing sites such as high septal or RVOT has been suggested. Previous studies have however been conflicting. The aim of this study is to determine if bi-ventricular pacing from RVOT + LV is better than RVapex+LV. To avoid influence from possible atrial delay only patients with chronic atrial fibrillation are included. All patients will receive a bi-ventricular pacemaker with 3 leads placed in RVapex, RVOT and via coronary sinus to pace the left ventricle. After a run in period (to determine if AV-junction ablation is necessary) the patients are randomised to one of the following pacing configurations: RVOT+LV or RVapex+LV with cross-over after 3 month.

This is a prospective double blind trial of intraoperative transmyocardial bone marrow-derived mesenchymal cell transplantation vs placebo in patients with low left ventricular ejection fraction scheduled to coronary bypass operation.

Evaluation of an intracoronary injection of ex-vivo generated autologous Angiogenic Cells Precursors (ACPs) to treat patients suffering from severe angina not responsive to maximal drug treatment or not willing or without option of undergoing percutaneous coronary intervention (PCI) or coronary artery bypass graft surgery (CABG). The use of ACPs aims to promote the formation of new vascularization and thus viable myocardial tissue.

The aim of this study is to compare the effect of treatment with verapamil or carvedilol on long-term outcomes in stable, chronic heart failure secondary to non-ischemic cardiomyopathy.
