[Coronary atherosclerosis, coronary thrombosis and myocardial infarction in autopsy cases. VII. Communication: Complications in myocardial infarctions (author's transl)].

2393 cases of myocardial infarctions autopsied during the period from 1.1. 1951 until 31. 12. 1969 in our Institute were scored for aneurysm and rupture of the cardiac wall as well as for partietal thrombosis and endocardial fibrosis, and analysed concerning frequency and distribution of sex. Aneurysm of the ventricle walls was present in 23.94 per cent of myocardial infarctions. Most of the aneurysms were found in the posterior wall of the left ventricle. Callous infarctions showed more aneurysms than fresh myocardial lesions. A rupture was present in 31.82 per cent of acute aneurysms and in 4.53 per cent of old aneurysms. Parietal thromboses we found in 13.92 per cent of all infarctions. In 14.21 per cent of all myocardial infarctions endocardial fibroses were present. Parietal thromboses and endocardial fibroses were significantly most frequent in infarctions of the right ventricle.
