Cardiac MRI-Derived Pressure-Volume Loop Analysis in Heart Failure With Preserved Ejection Fraction

Discriminative and Prognostic Value of Myocardial Energetics and Pressure-Volume Loop Parameters Derived From Cardiac MRI in Heart Failure With Preserved Ejection Fraction

Source: ClinicalTrials.gov · Last updated 28 Jan 2026

Brief summary (registry, in English)

This is a multi-center, observational study designed to evaluate the discriminative and prognostic value of pressure-volume (PV) loop analysis parameters and myocardial energetics derived from cardiac MRI in patients with heart failure with preserved ejection fraction (HFpEF). This study plans to enroll 3000 adult HFpEF patients and 500 adult healthy controls. The primary clinical endpoint was a composite of all-cause mortality and heart failure hospitalization, with events ascertained through medical records, clinic visits, and telephone follow-up. This study aims to determine whether cardiac MRI-derived PV loop analysis parameters and myocardial energetics provide incremental discriminative and prognostic information beyond conventional cardiac MRI parameters in patients with HFpEF. The study is non-interventional and does not involve any investigational drugs or devices.
