تاثیر بازتوانی قلبی بر وضعیت همودینامیک بیماران بعد از جراحی بای پس عروق کرونر

Background: Today, coronary artery bypass graft surgery (CABG) in many patients is commonly used to treat complications of the disease. Aim: This study aimed to evaluate the impact of cardiac rehabilitation on hemodynamic parameters in patients undergoing CABG. Methods: : In this clinical trial which was conducted in Rajaee Hospital of Tehran University of Medical Sciences 100 patients after coronary artery bypass graft surgery procedure were randomly allocated into two experimental and control groups. Phase 2 of cardiac rehabilitation program was conducted for 24 sessions for the experimental group and the control group received the routin program. To collect the demographic data and hemodynamic parameters, demographic questionnaire and hemodynamic check list were used. Data were analysis with SPSS software Version 17 using Chi-square and independent T-test and also repeated measurements ANOVA. Results: The experimental and control groups were not significantly different in terms of demographic variables. There was a significant difference in the mean score of  heart rate 8 weeks after rehabilitation program between experimental and control group, i.e. the heart rate was 5 beats per minute lower in the experimental group (P = 0.006). No significant difference was seen in other hemodynamic parameters in two groups. Conclusion: The results indicate that cardiac rehabilitation program could relatively improveme some of the hemodynamic parameters.  Therefore, more attention to the implementation of cardiac rehabilitation programms is necessary.
