Abstract

Background. The relevance of the comparative study of exercise tolerance in male and female cardiac patients is due to the need to individualize physical rehabilitation programs.

Aims: to study the impact of gender on exercise tolerance in patients with acute coronary syndrome undergoing a course of rehabilitation in a day hospital.

Methods. 110 patients with acute coronary syndrome were examined: 81 men (73.6%) aged 34 to 75 years and 29 women (26.4%) aged 44 to 74 years. In accordance with the purpose of the study, all patients were exposed to stress testing before and after the end of the three-week rehabilitation course.

Results. According to the analysis of the six-minute walk test and the Bicycle ergometric test, men had better physical endurance than women. Features of hemodynamic indicators during physical activity also correlate with gender: in comparison with men, the maximum physical load in women was accompanied by higher heart rate values. At the end of the rehabilitation course, women had a more pronounced improvement of Bicycle ergometry indicators: a greater increase in maximum power and the percentage of load performed during the test.

Conclusions. The gender differences in exercise tolerance in cardiac patients identified in the study should be taken into account when designing rehabilitation programs.
