The Role of Mineralocorticoid Receptor Antagonists in the Management of Heart Failure with Preserved Ejection Fraction

Abstract

Background: Heart failure with preserved ejection fraction (HFpEF) is associated with increased risk for hospitalization and all-cause mortality. Currently, there is no established treatment to improve the survival of these patients. Aldosterone appears to play a role in the pathogenesis of HFpEF. Objective: To discuss the findings of studies that evaluated the effects of mineralocorticoid receptor (MR) antagonists on the outcome of patients with HFpEF. Methods: PubMed was searched for relevant papers. References of retrieved articles were also evaluated for pertinent material. Results: Accumulating data suggest that MR antagonists might be useful in the management of patients with HFpEF. However, existing evidence is limited and conflicting. Conclusions: More studies are needed to clearly define the therapeutic potential of MR antagonists in HFpEF. Given the heterogeneity of this disease and the low specificity of the criteria used for its diagnosis, it is also important to improve the definition of HFpEF and include appropriately selected patients in these studies.
