Troubled NHLBI TOPCAT Trial Disappoints

Although a significant portion of people with heart failure have preserved ejection fraction, none of the proven heart failure therapies has been shown to be beneficial in this important and growing heart failure subpopulation. Now a new NHLBI-funded study has failed to find a benefit in this group for spironolactone, which is a cornerstone of therapy for heart failure patients with reduced ejection fraction. But trial investigators and heart failure experts believe it is too early to dismiss hope that spironolactone and other aldosterone antagonists– including Pfizer’s Inspra (eplerenone)– may eventually be found to work in this population.

TOPCAT (Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist), published in the New England Journal of Medicine, randomized 3,445 patients with heart failure with preserved ejection fraction (HFPEF) to either spironolactone or placebo.
