Introduction: The Quality of Life (QOL) after Coronary Artery Bypass Grafting (CABG) is an important contributor to morbidity and mortality. The addition of Yoga Based Lifestyle Program (YLSP) to conventional cardiac rehabilitation has found useful and effective in improving ejection fraction and reducing risk factor profiles. Aim: The aim of the present study was to evaluate the effect of add-on YLSP to conventional post-CABG rehabilitation and to compare the changes of QOL. Materials and Methods: A total of 300 patients posted for elective CABG at Narayana Hrudayalaya Super Specialty Hospital, Bengaluru, India were randomised into two groups (150 each) i.e., Conventional Lifestyle Program (CLSP) and YLSP. Data on CLSP (95) and YLSP (102) was available for analysis at one year follow up. The YLSP Group practiced integrated yoga module including Yama, Niyama, Anasa, Pranayama and Meditation as an add-on to conventional lifestyle advice. Assessments were done before and one year after CABG on World Health Organization Quality of Life- Brief form questionnaire (WHOQOLBREF) with four domains viz., ‘Physical Health’, ‘Mental Health’, ‘Social relationships’ and ‘Environmental health’. As the data was not normally distributed, the non-parametric tests viz., Mann-Whitney Test and Wilcoxon signed ranks test for between group and within group comparisons were applied. Results: In YLSP group, significant (p<0.001; Wilcoxon’s test) improvements were found within group after one year in all domains of WHOQOL-BREF, while there was significant improvement (p<0.05; Wilcoxon’s test) only in the Social health domain, in the control (CLSP) group. There was significant differences between groups (p<0.05; Mann-Whitney test) in all domains with better improvement in the YLSP Group. Conclusion: Addition of integrated yoga program to conventional post-CABG rehabilitation leads to better improvement in all domains of quality of life after coronary artery bypass surgery.
