Abstract
to develop a risk score model for cardiovascular toxicity (CT) predicting, based on cardiovascular risk factors (RFs), RFs associated with cancer therapy, and troponin levels. The study included 76 BC patients with a prospective analysis of their clinical and treatment data, RFs, echocardiographic indicators before the start of treatment and after 6 months, and an increase in troponin level. Among all RFs, the most significant RFs of CT were: radiation therapy, treatment with anthracyclines, and cardiovascular diseases. Based on the obtained results, a combined CT risk score was developed and proposed.According to the sum of points, patients were divided into groups: group 1 - with a low risk of CT development, the sum of points < 5; group 2 - moderate risk, 6-7 points; group 3 - high risk, > 8 points. In a pilot prospective study, an analysis of the RFs of CT was provided, compared to echocardiography data and the degree of troponin increase in dynamic observation; the risk score model for the CT prediction was developed for BC patients stratification. According to the developed score, BC patients with a total of > 8 points are considered to have a high risk of CT complications. The use of the proposed risk model score with calculation of the RFs of CT along with high-sensitivity troponin increase during cancer treatment allows predicting the risk of CT developing at the early stages - before the onset of clinical manifestations. Accordingly, these BC patients have a high risk of CT, and the use of personalized cardiac monitoring together with cardioprotective therapy can prevent cardiovascular complications.
