Active clinical trials for "Heart Failure, Diastolic"

The purpose of this study is to examine the effects of weight loss via hypocaloric diet (CR)and aerobic exercise (AT) compared to the effects of weight loss via hypocaloric diet (CR), aerobic training (AT)and resistance training (RT).

In patients with Doppler echocardiographic signs of elevated LV filling pressures despite preserved LV systolic function after AMI treatment with the phosphodiesterase inhibitor sildenafil 40 mg three times daily for 9 weeks will compared with placebo Improve resting LV filling and cardiac hemodynamics. Improve exercise capacity. Improve filling pattern and cardiac hemodynamics during exercise.

Up to half of all patients with clinical features of heart failure are found to have normal heart pumping function. Recently the investigators have shown that a drug called perhexiline markedly improved exercise capacity and symptoms in patients with heart failure associated with impaired cardiac pump function. In this proposal the investigators will assess whether perhexiline has beneficial effects in patients with heart failure and a normal heart pumping function.

Diastolic heart failure is now being recognized as a key form of heart failure in older people. The focus of this research is to study ways to improve and maintain physical activity and functioning. This knowledge may improve the health and well-being in people with diastolic heart failure.

The purpose of this study is to examine whether spironolactone will improve exercise tolerance and quality of life in elderly patients with heart failure preserved ejection fraction (HFPEF).

The purpose of this study is to test the hypothesis that treatment with oral ALT-711 twice daily for 16 weeks will improve aortic distensibility, exercise tolerance, and quality of life in elderly patients with isolated diastolic heart failure (DHF), and that the improvements in exercise tolerance will correlate with the improvements in aortic distensibility.

Patients enrolled into the study will be randomly allocated either to Empagliflozin group or control group. In the Empagliflozin group patients will be receiving standard care + Empagliflozin 10 mg o.d., in the control group patients will be receiving standard care without sodium glucose contransporter 2 (SGLT2) inhibitors.

The purpose of this study is to investigate how exercise-base rehabilitation influences circulatory functions in patients with diastolic heart failure (DHF).

Heart Failure with preserved Ejection Fraction (HFPEF) accounts for 40-50% of all heart failure patients with a frequency of hospital admissions for acute decompensation and short and long term mortality similar to patients with heart failure with reduced ejection fraction (HFREF). Patients with HFPEF are often preload dependent and despite admission to the hospital for acute decompensated heart failure (ADHF), are typically difficult to diurese due to the development of acute kidney injury. No studies have been performed evaluating treatment strategies for these patients. The investigators hypothesize that changing the method of diuresis and/or the addition of low-dose dopamine for the treatment of ADHF in patients with HFPEF will reduce renal injury, resulting in a shorter length of stay, and decrease hospital readmissions over the ensuing year. This trial will randomize patients to either bolus or continuous infusion furosemide and then to either dopamine or no dopamine. The primary endpoint will be renal function at 72 hours as measured by change in Glomerular Filtration Rate (GFR). Secondary endpoints for readmission, functional capacity, quality of life, and amount of diuresis will also be collected.

BACKGROUND: Exercise intolerance is the primary symptom in older patients with heart failure and preserved ejection fraction (HFPEF), however little is known regarding its mechanisms and therapy. METHODS: 71 elderly stable, compensated HFPEF patients (age 70+1 years; 80% women) with controlled blood pressure were randomized into a 12 month follow-up (FU) double-blind trial of enalapril 20 mg per day (E) vs. placebo (P). Assessments included: peak exercise oxygen consumption (VO2); six-minute walk test; Minnesota Living with HF Questionnaire (MLHF); MRI; Doppler-echocardiography; and vascular ultrasound.
