[Enzyme diagnosis of liver dysfunction in acute myocardial infarct and its complications]

A complex of enzymatic tests, characterizing the liver function and cellular cytolysis in patients with acute myocardial infarction of various severities (without complications and with various types of complications and outcomes) was used in examinations over the first week of the disease. Significant changes in five of the seven tested enzymes were found: aspartate aminotransferase, glutamate dehydrogenase, sorbitol dehydrogenase, cholinesterase, alanine aminotransferase, the degree and incidence of changes in their activities being the lowest in the patients with acute myocardial infarction without complications, higher in those with this condition with isolated complications, still higher in those with combined complications and a favorable outcome, and the highest in those with combined complications and a lethal outcome. Secondary hepatopathy in patients with acute myocardial infarction augments as the complications develop, particularly in arrhythmia, disordered conductivity, and combined complications. Measurements of glutamate dehydrogenase and sorbitol dehydrogenase are recommended starting from the first day of the disease, of cholinesterase from the third day of the disease for a dynamic monitoring of the liver status in order to timely detect and correct hepatopathy and assess the status of patients with complicated acute myocardial infarction.
