Multimodal Cardiovascular Magnetic Resonance Imaging for Cardiometabolic Pre-HF and HFpEF

This is an observational study aiming to characterize the pathophysiological features and clinical significance of cardiometabolic early-stage heart failure using advanced multimodal cardiovascular magnetic resonance (CMR) imaging. The study will focus on patients with cardiometabolic risk factors such as diabetes, hypertension, and obesity who are in the pre-heart failure (pre-HF) stage or have heart failure with preserved ejection fraction (HFpEF). The study seeks to establish a full-chain imaging framework-from precise phenotypic classification and sensitive noninvasive diagnosis to individualized cardiovascular risk stratification. Participants will undergo multimodal CMR scans and comprehensive clinical evaluations and be followed up for primary outcome.
