Background & Objectives: Anxiety and stress aggravates ill health in coronary artery disease (CAD) patients and also reduces the efficacy of medical or surgical treatment. Only medical management is not sufficient in these patients, lifestyle modification is very important for such psychosomatic disorder. Overall quality of life deteriorates in these patients. Yoga is one such potential intervention module of alternative and complementary medicine that is emerging as a foundation of mind body medicine which improves their ability to withstand stressful stimuli and thereby their quality of life.  
Material and methods: 40 patients of stable CAD were recruited and Quality of life was assessed by using disease specific Seattle angina questionnaire (SAQ) and generic health status ‘SF-36’ questionnaire before and after 12 weeks of yogic lifestyle intervention during which they continued their conventional medical treatment.  Student’s paired T-test was applied to assess each domain of both the questionnaires. 
Results: The domains covered by SAQ (physical limitation, angina stability, angina frequency, treatment satisfaction & overall quality of life) and domains covered by SF-36 (physical functioning, social functioning, physical impairment, emotional impairment, emotions, vitality, pain and global health were found to be significantly improved in CAD patients after 12 weeks of yoga therapy. 
Conclusions: Overall quality of life improves in CAD patients by adopting a yoga based lifestyle. It can be used as a complimentary or adjunct therapy along with the conventional therapy for their treatment and rehabilitation.
