Filter by:The purpose of this study is to assess a dose titration scheme, of a new drug (BAY58-2667) given intravenously, to evaluate if this is safe and can help to improve the well-being, symptoms (e.g. breathing) and outcome of decompensated heart failure. Patients living with chronic heart failure have a risk of increased number of hospitalisations because of worsening of their condition (decompensated heart failure). The current treatment of acute heart failure consists of oxygen and medical treatment with vasodilators and positive inotropic agents (drugs, which should strengthen the pump function of the heart) which have their limitations. Therefore there is a need for new drugs in treatment of acute heat failure.
The purpose of the study is to determine if the combination of AVJ ablation followed by BiV pacing significantly improves functional status and exercise capacity compared to pharmacologic rate control in patients with chronic AF and depressed ejection fraction, regardless of rate or QRS duration.
The aim of the study is to determine the safety and feasibility of giving an adeno-associated viral vector expressing the sarcoplasmic reticulum calcium ATPase (SERCA2a), driven by the CMV promoter (AAV1-CMV-SERCA2a), to heart failure patients that have received a left ventricular assist device (LVAD) for an accepted clinical indication.
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.
Recent ACC/AHA/ESC guidelines recommend prophylactic ICD implantation in most patients with coronary heart disease and LVEF < 40%. Current Canadian guidelines recommend ICDs for primary prophylaxis in CAD patients with LVEF < 30% (Class I recommendation). There are very sparse data to recommend ICD implantation in patients with EF between 30 and 40 %. This study will randomize patients with CHD and an EF between 30 and 40% to ICD therapy vs. No ICD therapy. The primary outcome is mortality and the study is powered as a non-inferiority trial to test the hypothesis that mortality in patients with no ICD is not more than 1% greater (absolute yearly increase) than patients receiving an ICD.
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
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.
BACKGROUND Beta-blockers improve left ventricular (LV) systolic function and prognosis in patients with chronic heart failure. Both carvedilol and nebivolol have hemodynamic and clinical benefits in chronic heart failure (CHF), but it is unknown whether their pleiotropic properties may play a role in different subgroups of patients with CHF. OBJECTIVE: To compare the effects of nebivolol and carvedilol on LV function and clinical outcome in patients with chronic heart failure and reduced LV systolic function. METHODS: 160 hypertensive CHF patients, LV ejection fraction (EF) 40% and in New York Heart Association (NYHA) functional class II or III were randomly assigned to receive carvedilol or nebivolol therapy for 24 months. At baseline and after 24 months of treatment, all patients underwent clinical evaluation: echocardiogram and 6-minute walking test.
The purpose of the PRECEDE-HF study is to collect data to compare patients whose heart failure is managed using Cardiac Compass with OptiVol (which is a tool in the device that records information about the heart that doctors can use to help treat their heart disease) combined with standard treatment methods (Access Group) to patients whose heart failure is managed by standard treatment methods only (Control Group). This comparison will show if the additional monitoring provided by Cardiac Compass with OptiVol delays the time patients are first admitted to hospital for heart failure or delays the time to death.
The purpose of this study is to investigate the efficacy of optimized temporary biventricular pacing (BiVP) in patients undergoing open-heart surgery with preoperative LV dysfunction and an intraventricular conduction delay. This study will compare extended temporary biventricular pacing versus standard of care by assessing patients randomized to the two groups, from the conclusion of cardiopulmonary bypass, until the conclusion of pharmacologic circulatory support in the intensive care unit. In addition, effects of biventricular pacing will be tested in all patients, at three time points, using different measures of blood flow. Results from this research will demonstrate whether temporary BiVP improves cardiac output after open-heart surgery and whether ventricular pacing optimization increases cardiac output in this setting. Success would lead to the development of recommendations for use of BiVP postoperatively and would stimulate the development of pacemakers with appropriate features. The primary hypothesis is that the optimum pacing protocol (POPT) will increase cardiac index (CI) by 15% (from approximately 2.30 to 2.64 L/min/m2) compared to standard of care as measured by thermodilution 12-24 hours postoperatively. Secondary objectives include defining POPT at three time points within 24 hours of surgery. The investigator will examine which forms of cardiac dysfunction benefit from temporary pacing using direct and indirect measures of perfusion and cardiac function. The investigator will also analyze survival, length of stay, incidence of arrhythmias, and cost of postoperative care.
