The impact of exercise-only-based rehabilitation on depression and anxiety in patients after myocardial infarction

Abstract

The aim of the study was to assess the effectiveness of exercise training on depression, anxiety, physical capacity and sympatho-vagal balance in patients after myocardial infarction and compare differences between men and women. Thirty-two men aged 56.3±7.6 years and 30 women aged 59.2±8.1 years following myocardial infarction underwent an 8-week training programme consisting of 24 interval trainings on cycloergometer, three times a week. Before and after completing the training programme, patients underwent: depression intensity assessment with the Beck depression inventory; anxiety assessment with the state–trait anxiety inventory; a symptom-limited exercise test during which were analysed: maximal workload, duration, double product. In women the initial depression intensity was higher than in men, and decreased significantly after the training programme (14.8±8.7 vs. 10.5±8.8; PP<0.01). Of note, no depression and anxiety manifestation was found in men. Physical capacity improved significantly after the training programme in all groups, and separately in men and in women. Moreover, an 8-week training programme favourably modified the parasympathetic tone. Participating in the exercise training programme contributed beneficially to a decrease in depression and anxiety manifestations in women post-myocardial infarction. Neither depression nor anxiety changed significantly in men. The impact of exercise training on physical capacity and autonomic balance was beneficial and comparable between men and women.
