Abstract

Modern approaches used in breast cancer treatment resulted in increasing survival rates. However, significant adverse events such as сardiotoxicity and cardiovascular complications remain high. A lot of women experienced fatigue, arrhythmias, heart failure, ischemic heart disease, and pulmonary side effects induced by breast cancer treatment.

The objective: to determine the features of the factor structure of functional parameters in women with postmastectomy syndrome with different levels of functional state of the cardiovascular system.

Methods: analysis of sources of literature and empirical data; rheography, spirography, analysis of heart rate variability; anthropometry; mathematical statistics methods.

Results. a developed method for estimating the level of functional state of the cardiovascular system of women with postmastectomy syndrome based on age and objective indicators of central hemodynamics: heart rate, minute blood volume and left ventricular work, as well as their significant contribution to overall predicted level. Based on the values of the determined parameters and coefficients of multiple regression, criteria of levels of functional state of the cardiovascular system of patients with postmastectomy syndrome are determined. The proposed method allows to carry out rapid monitoring and with a high degree of probability to assess the functional state of the cardiovascular system of the patients with postmastectomy syndrome, as well as to determine the effectiveness of therapeutic, rehabilitation measures and make adjustments to the program of rehabilitation. Defined factors of the direction of the rehabilitation process with the integral account of the predicted level of the functional state of the cardiovascular system are in the manuscript. It has been identified that the hemodynamic factor has covered 22.37% of the dispersion in women with the low level of functional state, 21.24% – with the lower-than-average level, 22.06 – with the average level; expiratory – 17.15%, 16.74% and 17.48; vegetative – 11.21%, 13.29% and 12.97% at corresponding levels at outpatient rehabilitation stage.
Conclusions. obtained results are the basis for choosing priority means of physical rehabilitation during developing a program for the rehabilitation of women with postmastectomy syndrome with various levels of the functional state of the cardiovascular system.
