Evaluation of cardiovascular risk factors in women with left breast cancer of middle-aged and elderly age at the stage of chemotherapy and radiotherapy

The study was conducted to identify risk factors for cardiovascular complications in 38 women with HER2neu negative left breast cancer without severe cardiovascular pathology, related both to the clinical features of the patients and the treatmenbeing performed. Patients after radical mastectomy were hospitalized for chemotherapy (doxorubicin in a cumulative dose not exceeding 360 mg/m2) and 3D conformal radiation therapy on the left breast breast of chest radiation doses 39 Gy (equivalent to 48 Gy of normal functioning). Separation into groups was carried out depending on the age: from 20 to 59 years — 20 patients, from 60 to 74 years — 18 patients. It was revealed that the risk of cardiovascular complications in the Score Scale was significantly higher in elderly patients due to age, increased systolic blood pressure and hypercholesterolemia. These patients showed higher rates of BMI and abdominal obesity. The study of psychosocial factors has shown great importance of the transferred stress in the past. The patients of the second group showed high personal anxiety (55.4 ± 3.4, 95% CI 49,6–56,4). In 70% of middle-aged patients and 89% of elderly patients after chemotherapy and radiotherapy cardiotoxicity in the form of cardiac insufficiency of systolic and diastolic dysfunction and asymptomatic cardiac arrhythmias was revealed.
