New therapies for the treatment of heart failure with preserved ejection fraction
Abstract
PURPOSE: This review of chronic heart failure with preserved ejection fraction (HFpEF), including new and emerging evidence for treatment of patients with this condition, is intended to offer data supporting the use of specific agents for this patient population.
SUMMARY: Chronic heart failure is a major health concern affecting millions of Americans annually and remains a significant burden on the healthcare system. Heart failure is divided into categories based on left ventricular ejection fraction (LVEF). Current treatments for heart failure with reduced ejection fraction, defined by an LVEF of less than 40%, involve a variety of agents with established morbidity and mortality benefits. This is in stark contrast to directed treatments for patients with HFpEF, defined by an LVEF of greater than 50%. Treatments for this form of heart failure have been elusive until recently, when studies were published with sacubitril/valsartan and empagliflozin. Results of the PARAGON-HF trial suggested benefit from sacubitril/valsartan in patients with an ejection fraction between 45% and 57%, leading to its approval in 2021 as the first medication indicated for treatment of patients with a preserved ejection fraction. Months later, the results of the EMPEROR-Preserved trial demonstrated a statistically significant benefit in the composite outcome of heart failure hospitalizations and cardiovascular death in patients with HFpEF taking empagliflozin. This medication has yet to gain…
