[Manifestations of cardiac decompensation in myocardial infarct]. / Ob osobennostiakh proiavleniia dekompensatsii serdtsa pri infarkte miokarda

A study of the causes of mortality among myocardial infarction patients and of the peculiarities of the manifestations of cardiac decompensation was conducted by way of mathematical prognosing and with the aid of the "Mmirp-1" computer, and permitted to conclude on the necessity of distinguishing between the primary circulatory insufficiency in the acute period, and relapsing circulatory disorders. The prognosis in myocardial infarction permits indirect appraisal of the reserve capacities of the diseased heart. The results of the conducted study indicate that the primary circulatory disorders are 6 times as frequent as the relapsing ones and that half of the patients with signs of circulatory failure dies within the first day of the disease. The long-term prognosis is equally unfavourable for the patients with circulatory insufficiency signs in the acute period: by the end of the 2nd year only 4 of every 10 patients with primary circulatory disorders survive, and 1--2 of every 10 patients with signs of relapsing circulatory disorders, which should be taken into consideration when developing the methods of complex therapy.
