Abstract :

AIM; To assess the role of myocardial performance index in Acute STEMI patients and its value in relation to systolic, diastolic, clinical parameters and assessing prognostic value in morbidity prediction. METHODS AND RESULTS Study population consist of age and sex matched 60 patients and 30 controls, MPI was significantly higher in anterior infarcts than in inferior infarcts while it was 0.62±0.07 in anterior and 0.66±0.18 in anteroseptalMI as against 0.58±0.11 in inferior and 0.52±0.10 in inferior /lateral or posterior or RVMI respectively.MPI was significantly (P= 0.007 ) higher when the killip class of the patients increased, MPI has got inverse relationship with EF and direct relationship with Pts who developed complication . CONCLUSION We found from our study that MPI was found to be higher in Myocardial infarction patients especially in Anterior Infarcts, and MPI also has got good correlation with Killipclass , Systolic function parameters like LV dimension, volume, ejection fraction and fractional shortening as well as Diastolic function parameters like Deceleration time, IVRT,E/E ratio. MPI was also found to be higher in patients who developed complication such as Heart failure and post infarction angina than in patients who did not have any complication. Hence MPI can be used for assessing LV function as well as for predicting in hospital out come in acute ST elevation myocardial infarction patients
