[Ischemic heart disease and embolisms and thomboses in the lesser circulation].

All deceased with ischemic heart disease (IHD) -- 450 cases and with embolism and thrombosis in pulmonary circulation (ETPC) -- 601 cases were purposefully examined for a period of 10 years (1963--1972). In 75 of the examined a combination of IHD and ETPC was present. In 41 out of them only cicatrices of past infarctions were found and in 34 -- recent myocardial infarctions. In 14 of the examined (41%) it was established, clinically and morphologically, that ETPC are with a longer duration than the recent myocardial infarctions and very likely have played a role in their pathogenesis. The confirmation of acute ischemic changes in myocardium gives a support -- undulation of the myofibrils and fuchsinophylic necrosis in the deceased of ETPC without preceeding IHD. The cardiac hypertrophy and coronary atherosclerosis lead to an intensification of the myocardial ischemic alterations in ETPC.
