Emerging evidence for mineralocorticoid receptor antagonists in heart failure with preserved ejection fraction

Form a review:

Recent findings: Three randomized trials were reviewed: the Effect of spironolactone on diastolic function and exercise capacity in patients with heart failure with preserved ejection fraction: the Aldo-DHF randomized controlled trial; the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist trial; and its echocardiography substudy. The Aldo-DHF trial showed improvements in echocardiographic measures of diastolic function. In the Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist trial, hospitalization for heart failure was significantly reduced with MRA therapy with no difference in the primary outcome of cardiovascular death or hospitalization. In patients with high risk, however, there may be a reduction in cardiovascular mortality. We will also briefly discuss finerenone, a new generation MRA associated with a lower incidence of hyperkalemia.

Summary: New evidence shows that MRA therapy decreases left ventricular mass and left atrial size, reduces hospitalization, and may reduce cardiovascular mortality in patients with high risk.
