Active clinical trials for "Heart Failure"

The purpose of this study is to evaluate the effect of ivabradine on cardiovascular events in patients with coronary artery disease.

This study is designed to show that a new lead, which paces the left bottom chamber (left ventricle) of the heart, is safe. Using a lead on the left side of the heart has been shown to potentially improve heart failure symptoms. The shape and size of this new lead may make it a good choice for patients or physicians.

This is a prospective, open-labeled, multi-centric trial to evaluate the effect of bisoprolol (between low dose and high dose) on surrogate markers of heart failure in Korea.

The aim of this study is to evaluate the safety and efficacy on the transplantation of autologous human cardiac-derived stem cells (hCSCs) with the controlled release of basic fibroblast growth factor (bFGF) to severe refractory heart failure patients with chronic ischemic cardiomyopathy concordance with reduced left ventricular dysfunction (15%≦LVEF≦35%).

In heart failure (HF), a defective nitric oxide (NO) signaling may be involved in left ventricular (LV) diastolic abnormalities and LV remodelling progression. PDE5-inhibition, by blocking NO degradation and overexpressing cellular cyclic guanosine monophosphate (cGMP) pathways might be beneficial. Several short term studies have demonstrated safety and clinical improvement in stable heart failure (HF) patients. The purpose of this study is to test the effects on LV diastolic function, cardiac geometry and clinical status in a cohort of HF patients.

Dosing methods for digoxin, a drug used to treat heart failure, have not been updated in decades despite evidence in recent years suggesting that blood levels of digoxin achieved with traditional dosing practices may increase the risk of adverse events. We developed a simple dosing tool that targets lower blood levels of digoxin that have been associated with improved outcomes compared to higher blood levels. The aim of this study is to determine if this simplified dosing tool is more effective than standard digoxin dosing practices at achieving lower blood levels and also to determine if digoxin dosing may be further optimized by incorporating patients' genetic information believed to influence the drug's properties.

This trial will investigate the clinical and haemodynamic effects of temporary biventricular pacing after cardiac surgery. Subjects with poor left ventricular systolic function will receive either temporary biventricular pacing or 'standard' post-operative pacing for 48 hours. The investigators hypothesis that reversal of cardiac dyssynchrony will improve tissue perfusion and cardiac haemodynamics after surgical revascularisation. This will shorten post-operative recovery in cardiac ITU.

Patients with heart failure (HF) have a limited exercise tolerance,few pharmacological interventions have been proven effective in improving exercise capacity. At the presence there i conflicting evidence on the effectiveness of beta-blockers on exercise capacity. Ivabradine has been shown to improve prognosis in patients with ischemic heart disease, left ventricular dysfunction and heart rate > 70 bpm. The association of ivabradine and atenolol has been proven effective in increasing exercise tolerance in patients with ischemic heart disease. Aim of the present study is to evaluate the effect of heart rate reduction with ivabradine, carvedilol or their combination in patients with heart failure of ischemic origin.

The purpose of this study is to determine the safety and effectiveness of the HeartWare Ventricular Assist System in patients with chronic Stage D/ New York Heart Association (NYHA) Class IIIB/IV left ventricular failure who have received and failed optimal medical therapy, and who are ineligible for cardiac transplantation.

The purpose of this study is to determine if there is an interest to optimize HF (heart failure) management in patients over 80 years old. The primary objective is to assess the effect of HF (heart failure) optimized management (guidelines of the European society of Cardiology (ESC) on Quality of Life (QOL) in aged over 80 year's old at 6 months.
