BACKGROUND Wall-motion analysis during low-dose dobutamine echocardiography (LDDE) is a semiquantitative measure of left ventricular contractile reserve after myocardial infarction (MI). The Doppler(More)
BACKGROUND Myocardial viability can be detected by wall motion analysis during low-dose dobutamine echocardiography (LDDE) after acute myocardial infarction (AMI). However, wall motion analysis(More)
OBJECTIVES To test whether an increase in Doppler myocardial performance index (MPI) during dobutamine stress echocardiography, reflecting deterioration of overall left ventricular function, is(More)
