Nonlinear Relation between Cardiac Mortality and Excess Temperature in Heatwaves: Exposure Response in 2.39 Million Patients | JACC

Mar 31, 2025

In this podcast, Dr. Valentin Fuster discusses a groundbreaking study examining the non-linear relationship between cardiac mortality and heat waves, focusing on how excess temperature during these events can impact heart disease death rates. The study reveals that compound heat waves, involving both day and night temperatures, significantly increase mortality risks, emphasizing the need for more precise heat wave definitions and health measures to protect vulnerable populations in a warming climate.
