This systematic review of randomized controlled trials (RCTs) aimed
to evaluate the quality of evidence and the strength of recommendation for yoga
as an ancillary intervention for heart disease. METHODS: Medline/PubMed, Scopus,
the Cochrane Library, and IndMED were searched up to October 2013. Main outcome
measures were mortality, nonfatal cardiac events, exercise capacity,
health-related quality of life, and modifiable cardiac risk factors. Risk of
bias, quality of evidence, and the strength of the recommendation for or against
yoga were assessed according to the Cochrane Collaboration and GRADE
recommendations. RESULTS: Seven RCTs with 624 patients comparing yoga to usual
care were included. For coronary heart disease (four RCTs), there was very low
evidence for no effect on mortality, for a reduced number of angina episodes, and
for increased exercise capacity, and low evidence for reduced modifiable cardiac
risk factors. For heart failure (two RCTs), there was very low evidence for no
effect on mortality, and low evidence for increased exercise capacity, and for no
effect on health-related quality of life. For cardiac dysrhythmias treated with
implantable cardioverter-defibrillator (one RCT), there was very low evidence for
no effect on mortality, and for improved quality, and low evidence for effects on
nonfatal device-treated ventricular events. Three RCTs reported safety data and
reported that no adverse events occurred. CONCLUSIONS: Based on the results of
this review, weak recommendations can be made for the ancillary use of yoga for
patients with coronary heart disease, heart failure, and cardiac dysrhythmia at
this point.
