Multicenter Study Clinical Trial
[Intraventricular thrombi in acute myocardial infarct. The Iberian Multicenter Study. Presentation of the study protocol and various preliminary results].
To evaluate the incidence of left intraventricular thrombosis and systemic embolism after acute myocardial infarction, as well as to determine the risk factors of each one of them. To study the morphologic aspects of the thrombus and its relation with systemic embolism. CONCEPTION AND POPULATION: 1505 consecutive patients with acute myocardial infarction from six Iberian Hospital Coronary Care Units--five from Spain and one from Portugal--were studied. All protocols included a clinical evaluation and a M-mode and 2D echocardiographic study at days 1, 3, 7 at hospital discharge, as well as at months 1, 3, 6, 12, and 24 of the follow-up. In the intraventricular thrombus evaluation just the III and IV Asinger grades were considered. ⋯ A high incidence of left intraventricular thrombosis after acute myocardial infarction correspond to a low incidence of systemic embolism. Some parameters correlated with intraventricular thrombus or with embolism, what allowed us to consider them as risk factors of these clinical entities.
