Key result
A Myocardial Performance Index > 0.72 predicted early in-hospital heart failure after acute STEMI with 77.3% sensitivity and 93.6% specificity, compared to 57.5% and 93.4% for ejection fraction.
Why the study?
Ejection fraction and transmitral flow have considerable limitations for assessing LV dysfunction after myocardial infarction, whereas MPI evaluates both systolic and diastolic performance combined.
Does the Myocardial Performance Index (MPI) predict early in-hospital heart failure in patients with acute STEMI post-thrombolysis?
Observational (n=100)
Does the Myocardial Performance Index (MPI) predict early in-hospital heart failure in patients with acute STEMI post-thrombolysis?
p-value: p=0.0001
Myocardial Performance Index (MPI) is a highly sensitive and specific echocardiographic predictor of early in-hospital heart failure in patients with acute STEMI following thrombolysis, demonstrating better sensitivity than ejection fraction.

Nambirajan et al. (2022) conducted an observational in Acute ST elevation myocardial infarction (STEMI) (n=100). Myocardial Performance Index (MPI) vs. Ejection Fraction (EF) was evaluated on Early in-hospital heart failure (Killip class >= II) (p=0.0001). A Myocardial Performance Index > 0.72 predicted early in-hospital heart failure after acute STEMI with 77.3% sensitivity and 93.6% specificity, compared to 57.5% and 93.4% for ejection fraction.
