Active clinical trials for "Heart Failure"

The purpose of this prospective, randomized, open-label study is to compare two diuretic strategies in patients with acute decompensated heart failure (ADHF): the addition of an oral thiazide diuretic to intravenous bolus (IVB) loop diuretic will be compared to transition from IVB to continuous infusion (CI) loop diuretic.

Heart failure is a major health problem in Canada. Recent advances in medical and device therapy have helped to reduce the morbidity and mortality of patients with this problem. Among these treatments, cardiac resynchronization therapy (CRT) has very recently been shown to be effective to improve functional class, quality of life and exercise tolerance of the patients with the most severe symptoms of heart failure and a prolonged duration of the QRS on the 12-lead Electrocardiography (ECG).

This study will evaluate the safety and effectiveness of Conivaptan, a vasopressin antagonist, in the treatment of hyponatremic subjects having symptomatic acute decompensated heart failure (ADHF).

The purpose for this study (CY 1124) is to evaluate the effects of CK-1827452, a cardiac myosin activator, on myocardial systolic performance, myocardial oxygen consumption, and myocardial efficiency in patients with heart failure and to confirm that the unique preclinical pharmacological profile of CK- 1827452 is substantially the same in patients with heart failure.

The purpose of Study 20060172 was to measure echocardiographic parameters and biomarkers in a subgroup of study subjects enrolled in Study 20050222 (the RED-HF Trial). This substudy 20060172 was terminated early due to feasibility constraints. All subjects enrolled in 20060172 were also enrolled in Study 20050222, which is ongoing. Study data will be analyzed when Study 20050222 ends, since unblinding before then would adversely affect Study 20050222.

The purpose of this study is to compare the safety of Pioglitazone, once daily (QD), to Glyburide in Type 2 Diabetes Subjects with Mild to Moderate Congestive Heart Failure

This study is being done to evaluate the safety and effectiveness of alagebrium in subjects diagnosed with diastolic heart failure. The primary assessment for effectiveness is the assessment of exercise tolerance.

The primary objective of this study is to assess the activity on breathing parameters of 4 escalating doses of AVE0657 in comparison to placebo in patients with Cheynes-Stokes Breathing Syndrome.

Many patients with heart failure are unable to increase their heart rate appropriately when their body needs increased blood flow. As a result, they may be unable to mobilize excess fluid that their body retains. We hypothesize that we can provide assistance to their body in mobilizing this fluid by artificially increasing their heart rate using a pacemaker. We plan to conduct a prospective clinical trial to evaluate this hypothesis. We will use a cross over design to study patients who already have biventricular pacemakers implanted or a narrow QRS and volume overload. We will screen them using a blood test that is a rough estimate of volume overload. Patients who meet the inclusion criteria will be randomly assigned to have their pacemakers adjusted or to have no intervention during the first of 2 visits. They will be unaware of which group they are in. Following adjustment, they will be monitored for six hours. Prior to the pacemaker adjustment, several tests will be performed to evaluate heart function and the levels of hormones related that are affected by heart failure. These tests will be repeated at the end of the six hour intervention period in each visit. At the end of the visit patients who had their pacemakers adjusted will have it reset to their original settings.

The purpose of this study is to determine the efficacy of a multi-disciplinary home program consisting of specific education and home-based individualized combined aerobic and resistance training exercise program for persons with heart failure (NYHA class II-III). The investigators will assess effects on endurance, gait speed, lower extremity strength, hospital re-admission rate and the quality of life in community-dwelling older adults from 60 - 85 years of age over a 12 month period. Anticipated Results: The researchers expect confirm their hypothesis that there will be a statistically significant difference between the experimental group receiving the combined aerobic and resistance training program and the control group receiving usual care based on strength, endurance, quality of life, falls, and hospital re-admission data.
