Impact of Persistent Microvascular Obstruction by Cardiac Magnetic Resonance on Prognosis for ST-segment Elevation Myocardial Infarction

The aims of the study were to evaluate the predictive value of persistent microvascular obstruction (MVO) by cardiac magnetic resonance for main adverse cardiac events in ST-segment elevation myocardial infarction patients. MVO in the acute phase of myocardial infarction has been considered to be strong predictor of a poor prognosis. We plan to explore the relationship between persistent MVO and the long-term prognosis of patients with STEMI. We made hypothesis that patients with persistent MVO have a poor prognosis.
