Analysis of heart morpho-functional parameteres and myocardial injury biomarkers during anthracycline chemotherapy

Anthracycline antibiotics are widely used in cancer treatment. Cardiotoxic (CT) side effects limit their using. The purpose of the study was to evaluate the echocardiographic parameters, troponin I and N-terminal prohormone of brain natriuretic peptide (NT-proBNP) levels dynamics in different age groups, receiving anthracycline chemotherapy (cumulative doxorubicin dose of 250 mg/m2). The study included 155 patients with hemoblastosis, treated with anthracyclines. Patients were divided into two groups on the age principle – the 1st group involved 67 patients aged from 18 up to 44 years, the 2nd – 88 patients aged from 45 up to 74 years. NT-proBNP and troponin I levels, echocardiographic examination were performed twice: at baseline and after chemotherapy. As a result of the study, it was revealed that the anthracycline treatment at a cumulative doxorubicin-equivalent dose 250 mg/m2 didn't lead to heart structural parameters changes – there were no significant (p > 0,05) differences between the different age groups in dynamics. The pulse-wave dopplerpulse showed-statistically significant differences initially and after chemotherapy in different age groups patients (p < 0,0001). Particularly, intergroup differences in E and E' values caused by age-related physiological processes of aging, and occurs as a left ventricular diastolic compliance violation due to age-related changes in the connective tissue matrix composition and structure. In both groups patients, receiving anthracycline antibiotic therapy, NT-proBNP and troponin I levels were significantly increased compared before chemotherapy measurement, but no significant intergroup differences were found (p > 0,05).
