Effect of Melatonin on Cardiovascular and Muscle Mass and Function in Patients With Heart Failure

Phase 2
Conditions
Heart Failure With Reduced Ejection Fraction
Interventions
Drug: Placebo Oral Tablet
Registration Number
NCT03894683
Lead Sponsor
Isfahan University of Medical Sciences
Brief Summary

The main aim of this study is to investigate the effect of melatonin on clinical outcome, quality of life, and cardiovascular function of the patients with heart failure, as well as its effect on their skeletal muscle mass and function.

Detailed Description

People with heart failure (HF) suffer from various comorbidities and complications which their management is as important as treatment of HF per se. An important complication of the HF is progressive decrease in muscle mass and function known as muscle wasting or sarcopenia. Prevention, diagnosis, and treatment of muscle wasting is emphasized to improve prognosis and quality of life of the patients with HF. Melatonin is a natural hormone which is secreted from pineal gland and is involved in circadian rhythm control. Recent data delineates more important roles for melatonin in cellular metabolism and apoptosis, as well as acting as an antioxidant and anti-inflammatory agent in the body. Experimental studies show that melatonin can have a beneficial role in muscle wasting in several chronic conditions such as heart failure. Furthermore melatonin has been shown to have valuable effects on cardiovascular health, blood pressure, and endothelial function and it might benefit patients with heart failure. In this study the effect of melatonin on clinical outcome and quality of life of the patients with HF and their echocardiographic parameters, muscle mass, muscle function, inflammatory biomarkers, serum metabolic parameters, and serum oxidative stress markers will be studied.
