Background: Comprehensive cardiac rehabilitation aims to restore pathophysiological and psychosocial consequences of myocardial infarction (MI). The aim of the study was to assess how exercise-only-based cardiac rehabilitation (ECR) influences the attitude to the therapy (ATT), to the aims in life and professional work (AAL) amongst men and women after MI. Material and Methods: The study comprised 44 post-MI patients: 28 men and 16 women, mean age 58±10 years old, referred to ECR. Patients underwent 24 interval cycle ergometer trainings 3 times a week. At the beginning and after the training program (TP) each patient underwent exercise stress test (EST) and was scored to ATT and ALL based on the Psychological Effects of Rehabilitation Score Scale (PERSS) according to Tylka and Makowska. The analysis covered: 1) EST findings: maximal workload and test duration (min), 2) ATT and AAL based on PERSS, 3) resuming professional work. Results: Exercise capacity improved significantly after TP. Attitude to the aims in life and professional work significantly increased in the whole group (4.4±2.8 vs. 5.1±2.4, p < 0.01) and separately in men (4.5±2.9 vs. 5.1±2.5, p < 0.05) and women (4.3±2.6 vs. 5.0±2.0, p < 0.05). Attitude to the therapy did not change significantly in the whole group (5.6±2.8 vs. 6.0±2.8) and in men (5.9±2.9 vs. 6.0±2.9), but increased significantly in women (5.0±2.5 vs. 6.1±2.7, p < 0.05). Professional work was resumed, averagely by 86.4% of all patients (85.7% men and 87.5% women). Conclusions: Physical training beneficially influenced post-MI men’s and women’s attitude to the aims in life, professional work and attitude to the therapy in women. Med Pr. 2019;70(1):1–7
