Implication of mineralocorticoid receptor antagonist esaxerenone in patients with heart failure with preserved ejection fraction


Advocate Christ Medical Center


The implications of mineralocorticoid receptor antagonists, including the newly introduced esaxerenone, on cardiac reverse remodeling in patients with heart failure with preserved ejection fraction (HFpEF) remain uncertain. We included patients with HFpEF who received esaxerenone for hypertension between November 2019 and July 2021 in this retrospective study. Changes in left ventricular mass index (LVMI) were compared between the 6-month pretreatment period (without esaxerenone) and the 6-month treatment period (on esaxerenone). Thirty-three patients (median age 74 years [interquartile range {IQR} 70-81 years]; 33% male, median systolic blood pressure [SBP] 135 mmHg [IQR 123-148 mmHg]) were included in the study and completed 6-month esaxerenone therapy without any adverse events. During the pretreatment period, SBP decreased significantly (P=0.009), whereas LVMI remained unchanged (P=0.30). During the esaxerenone treatment period, both SBP and LVMI decreased significantly (P=0.003 and P=0.001, respectively). Esaxerenone may have beneficial effects of reverse remodeling in patients with HFpEF when used to treat hypertension. Further studies are needed to understand which patient populations may see greater benefits with esaxerenone.
