Mitral annular plane systolic excursion (MAPSE) is known to have prognostic importance in the risk stratification of patients with acute myocardial infarction (MI). In post-MI patients with MAPSE<8mm, the combined mortality and hospitalization incidence is 43.8%. Similarly, CMR studies have shown that intra-myocardial haemorrhage (IMH) in the infarct core is an independent marker of prognosis. We hypothesised that the MAPSE on 4-chamber cine-CMR is correlated to left ventricular ejection fraction (EF) and to the presence of IMH.
Averaged MAPSE, which is a simple CMR derived parameter of longitudinal function, has the potential to predict the presence of IMH in the setting of re-perfused acute myocardial infarction. This parameter could be easily measured at bedside by transthoracic echocardiography to predict presence of IMH.
