[Peripheral circulatory changes in patients in the acute period of transmural myocardial infarct]

Altogether 107 patients with transmural myocardial infarction were investigated by determination over time the volumetric blood flow rate in the forearm using a plethysmograph with mercury-rubber gages and A-V oxyhemoglobin difference. With relation to a degree of expression of acute heart failure all the patients were divided into 4 groups. Considerable volumetric peripheral blood flow rate changes were noted in the acute phase of transmural myocardial infarction. A degree of a decrease in the rate well correlated with expression of clinical signs of heart failure. Indices of A-V oxyhemoglobin difference also showed correlation with expression of acute heart failure growing with its increase. The combined determination of these indices, probably reflecting 2 tendencies (blood flow decrease and centralization), is of certain prognostic value.
