Rehabilitation of athletes following cardiovascular events

Abstract

The relevance of this study lies in the fact that cardiovascular mortality decreases in countries promoting active healthy lifestyles. The authors conducted experimental studies of the cardiovascular parameter prediction accuracy at the initial and final stages of the rehabilitation process. The experiments showed sufficient accuracy of the constructed models. In particular, the maximum relative error was 11% for the simulation of the tolerable physical activity duration and 5.5% for the simulation of the exercise tolerance. The novelty of the study is that experimental studies were performed to predict the accuracy of the patient’s condition at the final stage of the rehabilitation process by the assessment of exercise tolerance using bicycle ergometry test data only at the initial stage. The experiments showed sufficient accuracy of the constructed method. In particular, the maximum relative error of blood pressure simulation at the final stage of the rehabilitation period was 5%. The authors propose an approach to the implementation of exercise monitoring, according to which the observed pulse values are supplemented by simulated pressure values. Experimental studies of the accuracy of the proposed approach have shown its sufficient accuracy. In particular, the maximum relative error in blood pressure simulation was 8.6%.
