Active clinical trials for "Heart Failure"

Sacubitril-Valsartan reduced heart failure hospitalizations and cardiovascular mortality compared to enelapril in chronic heart failure. Furthermore, quality of life is improved. The decrease of NT-proBNP levels during Sacubitril-Valsartan treatment is associated with reverse left ventricular remodeling and improved left ventricular systolic function. However, the underlying mechanisms that contribute to these symptomatic and prognostic benefits are largely unknown. The aim of this study is to evaluate left ventricular hemodynamics in patients treated with Sacubitril-Valsartan using non-invasive pressure-volume analysis.

This will be a FTIH study which aims to evaluate safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of single and repeat oral doses of GSK3884464 administered to healthy participants.

Heart failure is a growing epidemic that affects up to 500,000 individuals in Canada, with 50,000 new cases being diagnosed each year. Half of these will have HF with preserved ejection fraction (HFpEF). HFpEF has been associated with high rates of morbidity, mortality, and health care expenditures. Its pathophysiology remains poorly understood, and positive medication trial results to date have been rare. Inflammation is strongly associated with a profibrotic activation in HFpEF, which is in turn associated with the severity and prognosis of the disease. Colchicine is a potent anti-inflammatory drug which properties relate to the suppression of tubulin polymerization and inflammasome inhibition, thus reducing the production of IL-1β and IL-18. The investigators thus propose a pilot study of 6 months follow-up duration that will test the efficacy and safety of 2 dosing regimens of colchicine (vs. placebo) in patients with HFpEF.

To capture safety when Forxiga is administered to patients with HF in clinical practice after launch.

Patients in end-stage cardiac failure and/or respiratory failure may be started on a rescue therapy known as Extracorporeal Membrane Oxygenation (ECMO). One of the major clinical questions is how to manage the ventilator when patients are on ECMO therapy. Ventilator Induced Lung Injury (VILI) can result from aggressive ventilation of the lung during critical illness. VILI and lung injury such as Acute Respiratory Distress Syndrome (ARDS) can further increase the total body inflammation and stress, this is known as biotrauma. Biotrauma is one of the mechanisms that causes multi-organ failure in critically ill patients. One advantage of ECMO is the ability to greatly reduce the use of the ventilator and thus VILI by taking control of the patient's oxygenation and acid-base status. By minimizing VILI during ECMO we can reduce biotrauma and thus multi-organ failure. Since the optimal ventilator settings for ECMO patients are not known, we plan to study the impact of different ventilator settings during ECMO on patient's physiology and biomarkers of inflammation and injury.

The purpose of this study is to compare in patients with Advanced Chronic Heart Failure the effects of Levosimendan versus diuretic (single 24-hour infusion) applied at the early detection of impending destabilization on hospitalization-free survival during 12 months. Patients with advanced chronic heart failure (ACHF) have a short term reduced life expectancy with recurrent hospital admissions for clinical exacerbations. Levosimendan improves contractility by calcium-dependent binding to troponin C, determines vasodilation of the coronary arteries and systemic resistance vessels, thus decreasing preload and afterload, while exerting a protective effect on the myocardium against ischemia-reperfusion damage. In randomized clinical trials of acute heart failure patients, levosimendan improved hemodynamics and patients' quality of life and decreased natriuretic peptide plasma levels, with no excess mortality The study will assess whether the administration of levosimendan (single 24-hour infusion) at the early detection of deterioration may reduce frequency and duration of hospital admissions, improve functional status and quality of life in ACHF patients, with respect to diuretic infusion.

This is a pilot study comparing the effect of intra-coronary versus intramyocardial application of enriched CD133pos autologous bone marrow derived stem cells for improving left ventricular function in chronic ischemic cardiomyopathy.

This study is designed to evaluate the ImCardia safety and to demonstrate system functionality in patients undergoing AV replacement with respect to 36 months follow up.

This blinded, controlled study will examine the impact of pomegranate polyphenol extract (POMx, from Pom Wonderful, LLC), 1000mg on cardiomyopathy in subjects with chronic renal insufficiency.

Sleep Apnea (SA) is a disorder that causes pauses in breathing during sleep that expose the heart to oxygen deprivation. It is common in patients with heart failure (HF) where it is associated with increased risk of hospitalizations and death. It is not known however whether treating SA reduces these risks. This study is looking at whether a respiratory device known as Adaptive Servo Ventilation (ASV) can reduce the rate of cardiovascular hospitalizations and death in subjects with HF and SA. Study subjects will randomly receive either their regular medications OR their regular medications plus ASV. They will be followed for approximately 5 years and information relevant to their health will be collected and compared.
