A cardiac magnetic resonance imaging study in a subgroup of the patients in the SUMMIT trial of tirzepatide in patients with heart failure with preserved ejection fraction has demonstrated that patients treated with tirzepatide had reduced left ventricular mass and paracardiac adipose tissue compared to placebo-treated patients, which may partially explain the reduction in heart failure events observed in the main SUMMIT trial.
