The Effect of Neprilysin (LCZ696) on Exercise Tolerance in Patients With Heart Failure — NEPRIExTol  

Heart Failure Clinical Trial

Official title: The Effect of NEPRIlysin (LCZ696) on EXercise TOLerance, Muscle Vasodilatation, Muscle Strength and Body Composition in Patients With Heart Failure - NEPRIExTol-HF Trial

Status Completed

Clinical Trial Summary

Studies with new drugs in the treatment of heart failure (HF), such as the combination of valsartan/sacubitril, also known as LCZ696, have demonstrated important clinical impact on the morbidity and mortality outcomes in HF population. However, the effect of LCZ696 on the pathophysiological mechanisms of HF such as exercise tolerance (peak VO2) and peripheral muscle blood flow is not known. Since LCZ696 is a new drug with promising effects on the treatment of HF, the objective of the present study will be to evaluate the effect of LCZ696 in patients with HF on: 1) peak VO2, 2) 6-minute walk test, 3) peripheral muscle blood flow, 4) muscle strength, and 5) body composition.

Clinical Trial Description

Heart failure (HF) with reduced ventricular ejection fraction is a disease that affects around 5.7 million people in the United States, with a mortality rate of approximately 50% within 5 years. HF is characterized by an exacerbation of the renin-angiotensin-aldosterone system (RAAS), which leads to an increase in sympathetic nerve outflow, peripheral vasoconstriction, and reduced functional capacity. Moreover, many clinical trials have been developed for the treatment of HF patients focused on inhibition of RAAS, such as enalapril. Nevertheless, hospitalization and mortality rates in this population are excessive. However, studies with new drugs, such as the combination of valsartan/sacubitril, also known as LCZ696, have demonstrated important clinical impact on the morbidity and mortality outcomes in HF population. However, the effect of LCZ696 on the pathophysiological mechanisms of HF such as exercise tolerance (peak VO2) and peripheral muscle blood flow is not known. Since LCZ696 is a new drug with promising effects on the treatment of HF, the objective of the present study will be to evaluate the effect of LCZ696 in patients with HF on: 1) peak VO2, 2) 6-minute walk test, 3) peripheral muscle blood flow, 4) muscle strength, and 5) body composition. ;
