[Doppler echocardiography in myocardial infarction and its complications].

Echocardiography has established an important role in the surveillance of patients with myocardial infarction. Segmental wall motion abnormalities are easily identified and their extension reflects the size of the infarct. Global left ventricular function may be assessed and left ventricular dilatation documented. This information is useful in evaluating the long-term prognosis. In addition, Doppler echocardiography is valuable for detecting complications persisting or occurring after the acute phase such as pericardial effusion, mural thrombus, aneurysm or mitral regurgitation. The indications of Doppler echocardiography should be guided by the symptomatology and the results of clinical examination.
