Active clinical trials for "Heart Failure"

The objective of this investigation is to demonstrate non-inferiority in outcome of Custodiol-N against Custodiol in heart transplantation.

This study will evaluate how the cardiovascular system interacts with mechanical hearts to provide blood flow to the body during exercise. Two aims are proposed: 1) to determine the impact of a mechanical heart on exercise pressor reflexes in heart failure patients; and 2) to define the primary determinant(s) of exercise capacity in heart failure patients before and after device implantation.

Patients are randomised to receive ongoing optimised device and medical therapy or triple ventricular site resynchronisation. The hypothesis states that patients receiving triple-site resynchronization will exhibit a better response.

The aim of this study was to compare the response to cardiac resynchronization therapy when the interventricular pacing interval was optimized by Tissue Doppler Imaging (TDI) to response when it was optimized following QRS width criteria.

This study is investigating whether a series of psychological exercises, called positive psychology, provides benefit to patients who have been hospitalized for heart disease (an 'acute coronary syndrome' or heart failure). In this study, subjects are randomly assigned to complete 8 positive psychology exercises over 8 weeks, or to complete different exercises in control groups. We hypothesize that patients who are assigned to the positive psychology tasks will be able to complete the exercises at a high rate, will feel that the exercises were easy to perform, and will have greater improvements of optimism, anxiety, mood, and health-related quality of life than subjects in the control conditions.

The purpose of this research study is to test a program developed to help patients with chronic heart or lung problems take care of themselves and cope with their illness or limitations.

This is a randomized controlled trial of telemonitoring vs usual care provided by home care agencies for patients with heart failure. The study hypothesis is that Telemonitoring will reduce hospital re-admission rates, urgent care visits, unscheduled physician appointments, Emergency Room visits in patients with heart failure over the 60 day post hospitalization period.

The CRUF trial is a prospective randomized monocentric trial comparing different impact of diuretics versus ultrafiltration on renal congestion, plasma refill rate, echocardiographic filling pressures, neurohormonal activation and biomarkers of Acute Kidney Injury (AKI).

Prevalence of heart failure (HF) with left ventricular (LV) diastolic dysfunction and preserved ejection fraction (EF) (HFpEF) is increasing. Prognosis worsens with development of pulmonary vasoconstriction and hypertension (PH) and right ventricular (RV) failure. The investigators aimed at modulating pulmonary vascular tone and RV burden in HFpEF due to high blood pressure (HBP), by using the phosphodiesterase-5 (PDE5) inhibitor sildenafil.

Heart failure is a clinical syndrome where the heart is unable to pump enough blood to satisfy the organism's metabolic needs. Heart failure has become a major clinical and public health problem with approximately 300,000 Canadians being affected. Atrial fibrillation is a rhythm disorder in which the upper chambers of the heart (the atria) are paralyzed by continuous electrical activity. Some of the continuous chaotic electrical activity in the atria travels to the lower cavities of the heart (the ventricles) causing then to beat irregularly and very rapidly. It is the most frequent cardiac arrhythmia, affecting 5% of individuals 65 years and older and it is associated with an increased risk of stroke. Both conditions (heart failure and atrial fibrillation) often co-exist in the same patient. Heart failure promotes atrial fibrillation and atrial fibrillation aggravates heart failure. The Atrial Fibrillation and Congestive Heart Failure (AF-CHF) trial is investigating whether preservation of normal cardiac rhythm influences mortality and morbidity. The AF-CHF study began in 2001 and 1,378 patients have been enrolled from 123 participating centres, in North America, South America, Europe, and Israel. The results of this trial which are expected in October 2007, will improve decision-making for the physician and will provide useful information to healthcare organizations responsible for the care of heart failure patients.
