We assessed for the first time the prognostic value of the ΔESPVR (difference between peak and rest end-systolic pressure-volume relation) index evaluated during dipyridamole stress-CMR in 196 patients with known or suspected coronary artery disease. During a mean follow-up time of 53.17±28.21 months 50 cardiac events were recorded. In the multivariate analysis the independent predictive factors for cardiac events were diabetes, a ΔESPVR index≤0.02 mmHg/mL/m2, and myocardial fibrosis.
