Exercise-based rehabilitation programmes are expensive, and in certain subgroups uptake is poor. Yoga has been suggested to show improvements in cardiovascular health which would support its use in cardiac rehabilitation programmes. We carried out a review of current randomized controlled trials to determine if yoga-based cardiac rehabilitation leads to reduced cardiac risk factors, and improved physiological and psychological outcomes in patients with coronary artery disease compared to standard care. Six randomized controlled studies were identified after a medical database search, and meta-analysis was carried out for the different outcomes. Overall, the addition of yoga to standard care resulted in improved subjective feeling of cardiac health and quality of life. There was also a trend towards improvement in left ventricular systolic function. Improvement in cardiac risk factors, MACE and psychological health in this cohort has still to be proven, but was not inferior to standard or enhanced care, and the benefits became more pronounced at longer follow-up. Future studies with longer follow-up and larger patient numbers would aid in accurately assessing the long-term benefit of yoga-based rehabilitation.Keywords: yoga, cardiac rehabilitation, coronary artery disease
