Epidemiology and Outcomes in HFimpEF | JACC Deep Dive

Jul 28, 2025

In this JACC Deep Dive, Editor-in-Chief Harlan M. Krumholz, MD, SM, discusses a large real-world study by Min et al. examining heart failure with improved ejection fraction (HFimpEF) in over 24,000 patients. The study found that while EF improvement is common (30%), true remission is rare and relapse occurs in about 25% of cases—highlighting the need for continued guideline-directed medical therapy (GDMT) even after apparent recovery. Listen to the podcast, find out what reviewers and editors liked about the paper, and get more insight into our dedicated focus issue on heart failure.
