Mineralocorticoid Receptor Antagonists (MRA) in Heart Failure (HF) and Loop Diuretic Resistance

Heart Failure Clinical Trial

Official title: Pilot Study of Natriuretic Versus Standard Doses of Mineralocorticoid Receptor Antagonists in Heart Failure and Loop Diuretic Resistance in Outpatients

Status Completed

Clinical Trial Summary

This is a prospective, single-center, double-blind and randomized placebo controlled trial for evaluation of a 7-day 100mg daily dose of spironolactone on weight loss and resolution of signs and symptoms of congestion in outpatients with acute decompensated heart failure (ADHF). Patients who are not responding to their current loop diuretics will be considered for this study. Mineralocorticoid receptor antagonists (MRAs) are recommended as standard of care in management of heart failure (HF) patients. However, recommended doses of MRAs (spironolactone 25mg/daily or eplerenone 50mg/daily) will not have any impact on signs and symptoms of volume overload. Therefore, the proposed study will aim to show the impact of this outpatient regimen to improve diuresis and possible reduction in hospitalization for further diuretic management in HF patients with signs and symptoms of congestion.

Clinical Trial Description

The incidence and prevalence of heart failure (HF) is rising with more than 5 million Americans suffering from this syndrome. Hospitalization rates for acute decompensated heart failure (ADHF) are also remarkably high, exceeding more than 1 million admissions per year. Congestion is the main cause of hospitalization for ADHF. Loop diuretics as the main therapy for decongestion, often are not adequate since many patients with ADHF develop "loop diuretic resistance". These patients will require hospitalization for intravenous diuretic or other advanced decongestion therapies. Thus, novel decongestion therapies are needed to decrease hospital admission rates and subsequent complications of multiple hospitalizations. Hyperaldosteronism, not only is a pivotal pathogenic factor in HF, but also contributes to loop diuretic resistance. Attempts for normalization of circulatory aldosterone with mineralocorticoid receptor antagonists (MRAs), mainly spironolactone, have shown to decrease mortality in HF patients with reduced left ventricular ejection fraction (LVEF). Moreover, MRAs significantly decrease the rate of rehospitalization in both HF with preserved and reduced LVEF. The dose of spironolactone in these trials is 25mg daily. However, this dose does not increase natriuresis (urinary sodium excretion). Natriuresis is achieved with higher doses of MRAs. Therefore, the primary aim of this study is to examine the efficacy of 7-day 100mg daily of spironolactone on weight loss and resolution of signs and symptoms of congestion in patients aged 60 years with ADHF and loop diuretic resistance. ;
