[The information content and predictive value of cardiac markers in myocardial infarction in the elderly.].

Myocardial infarction in old age is the leading pathology and cause of deaths. The aim of the study was to evaluate the prognostic significance and informative value of cardiac markers of blood in elderly patients with myocardial infarction. The study of cardiac markers in 107 patients with myocardial infarction at the age of 65-75 years and in 83 patients with myocardial infarction at the age of 50-60 years was carried out by immunochromatographic, bioluminescent methods and by electrophoresis on cellulose acetate, followed by the calculation of informativeness and prognostic coefficients. 95 persons aged 65-75 years without myocardial infarction served as control. Troponin T, brain natriuretic peptide, glucose-6-phosphate dehydrogenase and lactate dehydrogenase-1 have the most informative and prognostic significance in elderly patients with myocardial infarction. The use of these cardiac markers will improve the diagnosis and isolation of patients with myocardial infarction at high risk.
