Does dobutamine stress echocardiography predict late left ventricular function recovery in patients after acute myocardial infarction?
p-value: p=<0.001
Dobutamine stress echocardiography performed early after acute myocardial infarction is a useful tool for predicting late recovery of left ventricular function.
Mauro et al. (2005) conducted an observational in Acute myocardial infarction (n=37). Dobutamine stress echocardiography vs. Rest echocardiography was evaluated on Improvement in wall motion score (WMS) (p=<0.001). Dobutamine stress echocardiography improved wall motion score in 35% of patients and predicted late left ventricular function recovery with 72% sensitivity and 96% specificity.
