Age characteristics of risk cardiovascular complications in women with left breast cancer with preserved ejection fraction at the stage of chemotherapy and radiotherapy

Abstract

Aim. A study of the risk factors for middle-aged and elderly women HER2neu with negative left breast cancer and a normal ejection fraction at the stage of chemoradiotherapy in everyday clinical practice. Matherial and methods. 61 women with left breast cancer without severe cardiovascular pathology were examined at the stage of doxorubicin therapy and 3D conformal radiation therapy. Group 1 comprised 32 patients of middle age (49.8 ± 4.5 years). Group 2 comprised 29 elderly patients (68.3 ± 3.6 years). In addition to Score risk assessment, additional factors, including psychosocial factors, were studied. All patients underwent ECG, echocardiography and 24-hour ECG monitoring. Anxiety levels were assessed using the HADS scale and scale CH. D. Spielberger - Yu. L. Khanin. The study was conducted before the start of treatment, after the completion of the doxorubicin course and after the completion of the course of radiotherapy. Results with discussion. In middle-aged patients, moderate Score risk was found in 21.9%, in the elderly at 58.6% (p = 0.0043, RR 2.68, 95% CI 1.301-5.520). A high Score risk was found in 15.6% of middle-aged patients and 41.4% of elderly patients (p = 0.0438, RR 2.648, 95% CI 1061-6.607). The most common risk factors in the patients studied in addition to age were heredity, overweight, hypercholesterolemia and diabetes mellitus. All examined patients had moderate reactive anxiety. Patients of middle age have moderate personal anxiety, in elderly patients high personal anxiety. After treatment with doxorubicin in a cumulative dose not exceeding 360 mg/m2, a reduction in the ejection fraction below 50% was found in 6 middle-aged patients and 17.2% in elderly patients. Asymptomatic diastolic dysfunction was detected in 31.3% of middle-aged patients and 55.2% of the elderly. In patients of both groups, after arranging treatment, arrhythmia was detected. Conclusions. The obtained data indicate to the need for in-depth examination of middle-aged and especially elderly patients with left breast cancer with an assessment of risk factors and conducting an in-depth examination using Echocardiography, 24-hour ECG monitoring and psychological testing to prevent and early detection of cardiovascular complications.
