title: [Value and limits of echocardiography of the acute or previous myocardial infarction. Mono- and bi-dimensional study (author's transl)].
abstract: 81 subjects with acute or previous myocardial infarction were studied in order to assess the relations between ecg location and diskinetic zones as seen on the echocardiogram; another purposes of the work was to establish if serial echocardiographic measurements would be useful for prognostic purposes. The obtained results were the following: 1) there is a good correlation between ecg location of anterior infarction and diskinetic or ipokinetic zones if on the echocardiographic pattern were simultaneously present the following echocardiographic findings: lessened systolic escursion + lessened systolic thickening + enhanced left ventricular diastolic dimension (LVDD); 2) in the group of posterior and inferior infarctions is observed either an ipokinetic left ventricular posterior wall either an ipokinetic septum; 3) left ventricle diastolic dimension (LVDD) was greater and the motion of the septum was less frequently paradoxical in previous infarction than in acute infarction; 4) there was a good correlation in anterior acute infarction among M-mode echo-patterns which indicate both progressive dilatation of the left ventricle and an abnormal septum movement and the appearance of congestive failure, shock and intrahospital mortality; 5) the aneurysms localized in apical section of the ventricles could be missed by M-mode studies and therefore when this complication is suspected bidimensional investigations are more indicated.
