Prognostic value of dipyridamole stress perfusion cardiovascular magnetic resonance in elderly patients >75 years with suspected coronary artery disease
European Heart Journal – Cardiovascular Imaging Aug 09, 2020
Pezel T, Sanguineti F, Kinnel M, et al. - This study is done to determine the prognostic worth of vasodilator stress perfusion cardiovascular magnetic resonance (CMR) among elderly > 75 years. Consecutive elderly > 75 years without known coronary artery disease referred for dipyridamole stress CMR were analyzed for this purpose. The development of major adverse cardiovascular events (MACE) including cardiac death or non-fatal myocardial infarction was noted during the follow-up. Inducible ischaemia was identified as an independent predictor of a higher incidence of MACE, in a multivariable Cox regression incorporating clinical features and CMR indexes. Findings demonstrated the safety as well as the discriminative prognostic worth of stress CMR in elderly, with a significantly lower event rate of future cardiovascular event or mortality in individuals without ischaemia or infarction.
