LDH in HFrEF — A Common Test, A Hidden Signal | JACC Baran

Hosts Mitsuaki Sawano, MD, Nobuhiro Ikemura, MD, and Satoshi Shoji, MD welcome Dr. Ryohei Ono, MD, PhD (BHF Cardiovascular Research Centre, University of Glasgow / Chiba University) to discuss his JACC: Heart Failure study, “Lactate Dehydrogenase and Outcomes in Patients With HFrEF: Insights From GALACTIC-HF.” The episode explores how LDH—one of the most commonly measured laboratory tests—may be a hidden gem for prognostication, reflecting systemic hypoperfusion and multiorgan stress in patients with advanced HFrEF and offering additional context beyond traditional cardiac biomarkers.
