Abstract

To determine the value of Myocardial Performance Index (MPI) as an echocardiographic predictor of early in-hospital heart failure (HF) during first acute anterior ST-Elevation Myocardial Infarction (STEMI). Myocardial infarction induces variable degrees of impairment in left ventricular (LV) systolic and diastolic functions. The ejection fraction (EF) and transmitral flow, the most frequently used methods for evaluation of systolic and diastolic functions respectively, both have considerable limitations. The MPI is a single parameter, capable of estimating combined systolic and diastolic performance and lacks such limitations. We enrolled 60 patients presented with a first acute anterior STEMI who have undergone primary PCI. Echocardiography was done within 24 h of chest pain with measurement of MPI. The LV MPI was calculated as (isovolumic contraction time "ICT" + relaxation time "IRT")/Ejection time "ET". Besides, clinical and echocardiographic variables were analyzed and CHF was defined as Killip class ≥ II. Early in-hospital HF occurred in 23 of patients (38%). Ejection fraction was found to have a highly significant negative correlation with the development of in-hospital HF (p = .0001), while MPI was found to have a highl...Continue Reading
