To investigate the value of the Doppler-derived myocardial performance inde
x to predict early left-ventricular (LV) dilation and cardiac death after a
first acute myocardial infarction (AMI), Doppler echocardiography was perf
ormed within 24 h of hospital admission, on day 5, 1 and 3 months after AMI
in 125 consecutive patients. The index measured on day 1 correlated well w
ith the change in end-diastolic volume index observed from day 1 to 3 month
s following AMI (r = 0.66, p < 0.0001). One-year survival in patients with
Doppler index <0.63 was 89%, and 37 % in patients with index greater than o
r equal to 0.63, (p < 0.0001). Multivariate analysis identified myocardial
performance index greater than or equal to 0.63 (relative risk 5.6, p < 0.0
001), E-wave deceleration time < 140 ms (relative risk 2.7, p = 0.008) and
Killip class greater than or equal to 11 (relative risk 4.0, p = 0.04) to b
e independent predictors of cardiac death. Therefore, we conclude that the
Doppler echocardiographic myocardial performance index is a predictor of LV
dilation and cardiac death after a first AMI. Copyright (C) 2001 S. Karger
