- Abstract
Abstract: In patients with acute myocardial infarction (AMI) a restrictive mitral inflow pattern successfully predicts clinical outcome. The impact of myocardial viability on the mitral inflow velocities, however, is unknown. One hundred and forty-one patients with a first AMI underwent two-dimensional, Doppler and dobutamine stress echocardiography (DSE). Patients were classified into two groups based on Doppler measurement of left ventricular filling: a restrictive group (18 patients), and a non-restrictive group (123 patients). In the non-restrictive group, myocardial viability at DSE was found in 56 patients, while in the restrictive group only three patients showed contractile reserve (46% vs. 16%, p <0.03). The multivariate logistic regression analysis demonstrated that restrictive mitral inflow pattern was a strong independent predictor of lack of viable myocardium (OR=12.45, p <0.001).
