Effects of Interval Training on Post-coronary Artery Bypass Grafting Hemodynamic Indices

Abstract

Objectives: There are conflicting reports on post-coronary artery bypass grafting (CABG) training programs that could have the most favorable impact on the hemodynamic state of patients. Therefore, the purpose of this study was to explore the effects of interval training on hemodynamic indices of patients following CABG. Materials and Methods: In this prospective quasi-experimental study (over the 4 months leading to July 2019), 24 patients were randomly selected based on a similar study. Among these patients, 12 cases (the training group) referring to Shahid Madani hospital of Tabriz received twelve 20-minute sessions of interval training over a month and their hemodynamic indices were measured before and after the intervention. The indices were then analyzed using the Shapiro-Wilk test, correlated t-test, and independent t test and P values lower than 0.05 were considered statistically significant. Results: The intergroup comparison of hemodynamic indices between training and control groups showed a significant difference (P≤0.019). In addition, the intragroup comparison of pre- and post-intervention results demonstrated significant improvements in all hemodynamic indices of the training group after the intervention (P≤0.010) while the changes were not significant in the control group (P≤0.118). Conclusions: In general, the interval training program in the post-CABG period improved hemodynamic indices and patient rehabilitation.
