| Abstract: | Echocardiographic data with calculation of the overall and segmental contractility have been obtained for 46 lethal cases with repeated macrofocal myocardial infarction. Mosaicism of the lesion having at least 2 isolated foci (zones of recent infarction and cicatricial changes) is a specific ECG feature for left-ventricular repeated infarction. Underlying mechanisms of mitral-papillar dysfunction in repeated infarction are shown as are the leading factors in the onset of severe cardiac failure most commonly resulting in death: absence of intact myocardium compensatory hyperkinesis and associated extensive affection of the left ventricle. |
