JACC Associate Editor Neha J. Pagidipati, MD, FACC, speaks with author Christopher M. Kramer, MD, FACC about this substudy of the SUMMIT trial published in JACC and presented at AHA, demonstrating that tirzepatide therapy in obesity-related HFpEF led to reduced LV mass and paracardiac adipose tissue as compared to placebo and the change in LV mass paralleled weight loss. These physiologic changes may contribute to the reduction in heart failure events seen in the main SUMMIT trial.
