5-YEAR RESULTS OF A CARDIAC REHABILITATION PROGRAM AFTER CORONARY ARTERY BYPASS SURGERY

Background: Coronary artery bypass surgery is a common method for coronary artery disease (CAD) treatment, which in turn activates pro-inflammatory biomarkers such as Interleukin-6 (IL-6) and high sensitivity C-reaction protein (hs-CRP). Objectives: The present study aimed to investigate the effects of 8 weeks Yoga and cardiac rehabilitation training on IL-6 and hs-CRP after coronary artery bypass surgery. Methods: The subjects of this randomized control trial study consist of 20 male patients (40 - 75 years old) who experienced coronary artery bypass surgery. They were randomly assigned in cardiac rehabilitation training group (CRT, n = 10) and combined training group (Yoga-cardiac rehabilitation) (YCRT, n = 10). Plasma levels of IL-6 and hs-CRP were assessed at baseline and end of the study. The CRT group performed cardiac rehabilitation program with 60% - 85% of maximum heart rate for 1 hour three days a week. The YCRT group performed one session in between cardiac rehabilitation and Yoga training for 1 hour three days in a week. All subjects completed training sessions at the cardiac rehabilitation center of Shahid Rajaie Cardiovascular, Medical and Research Center in Tehran for 8 weeks. SPSS software was used for analysis. Covariance analysis was used to compare groups (P ≤ 0.05). Results: Despite a small decline in IL-6 (10.90 to 8.77 in CRT group, 9.87 to 9.40 in YCRT group (and hs-CRP (2.58 to 2.00 in CRT group, 3.67 to 3.13 in YCRT group), there weren’t any significant differences in IL-6 (P = 0.160) and hs-CRP (P = 0.234) levels between two groups. Conclusions: It could be proposed to add Yoga training to cardiac rehabilitation program after coronary artery bypass surgery.

Artery Bypass Grafting

Background: The aim of this study was to evaluate the effect of cardiac rehabilitation on electrocardiographic changes in patients undergoing isolated coronary artery bypass grafting. Methods: Between January 2016 and July 2019, a total of 625 patients (485 males, 140 females; mean age: 59.6 years; range, 50.6 to 68.6 years) who underwent isolated coronary artery bypass grafting and survived were retrospectively analyzed. The patients were divided into two groups according to the participation in the cardiac rehabilitation program as follows: the Rehab(+) group (n=363) and the Rehab(-) group (n=262). Electrocardiographic parameters of both groups were compared. Results: There was a significant decrease in the electrocardiographic findings of heart rate (p<0.001), QTc (p<0.001), Tpe duration (p<0.001), Tpe/QT ratio (p<0.001), and Tpe/QTc ratio (p<0.001) in the Rehab(+) group before and after surgery. There was a significant decrease in the Rehab(+) group, compared to the Rehab(-) group, in terms of parameters of QT interval (p=0.001), QTc (p=0.017), Tpe duration (p<0.001), Tpe/QT ratio (p<0.001), and Tpe/QTc ratio (p<0.001). Conclusion: Cardiac rehabilitation program after coronary artery bypass grafting decreases ventricular repolarization indices of electrocardiography. Based on these changes, postoperative cardiac rehabilitation program may reduce the risk of ventricular arrhythmia and sudden cardiac death during follow-up.
