- W4233653663 abstract "Background: Cardiac magnetic resonance perfusion imaging (CMRPI) can assess myocardial perfusion, function and scarring. Its prognostic value in patients with established CAD is uncertain. We investigated whether the presence of inducible ischaemia on CMRPI predicts subsequent major adverse cardiovascular events (MACE). Methods: We reviewed 184 consecutive patients (64.5 ± 11.3 years) undergoing CMRPI. MACE was defined as death, myocardial infarction and readmissions related to cardiovascular morbidity. Elective revascularisation procedures were excluded. Results: The majority were European (84%) and 52% were male. 101(55%) patients had a prior diagnosis of CAD. Imaging was completed successfully in all but one patient who had limiting hypotension. Mean LV EF% was 61 ± 12%. Ischaemia was identified in 31% patients and scar in 39%. Median follow-up was 346 ± 226 days. MACE occurred in 12 patients. Ischaemia predicts subsequent MACE, for the entire cohort (graph) and for the subgroup with established CAD (p < 0.05 for both). The presence of scar did not predict outcome. Conclusion: CMRPI is safe and provides information on myocardial function, perfusion and scar. The presence of ischaemia predicts MACE, and importantly this predictive value is maintained in patients with known coronary disease." @default.
