the effects of 8 weeks yoga and cardiac rehabilitation training on interlukin-6 and high sensitivity c-reaction proteins after coronary artery bypass surgery: a randomized controlled trial

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.
