Background: Coronary artery disease (CAD) is a detrimental noncommunicable disease, which is increasing due to sedentary lifestyle and urbanization in the young population. It is further elevated with risk factors such as stress, anxiety, depression, an increase in triglycerides, dyslipidemia, hyperglycemia, hypertension, and so on, which manifests as atherosclerotic disease. Yoga-based lifestyle intervention is a noninvasive effective treatment method to control and prevent cardiac risk factors in CAD patients. Yoga has been used in India as a therapeutic method to manage hypertension and other chronic disorders and is fast gaining popularity as an effective means for the alleviation of stress, improvement of fitness, and enhancement of well-being. This study aimed to determine the feasibility of introducing the integrated approach of yoga therapy (IAYT) in a cardiac rehabilitation center in India and understand its usefulness in improving the cardiac function and managing the cardiac risk factors in acute myocardial infarction patients with left ventricular dysfunction. Methods and Design: Cardiac patients were randomized to a yoga-practicing group (n = 33) and a control group (n = 33). The yoga-practicing group was instructed to attend three supervised IAYT classes 3 days per week for 12 weeks at the hospital yoga center. The control group received standard care that included pharmacologic treatment and the instructions of the cardiologist. The outcome measures were assessed at baseline (T1 = 0) and completion (T2 = 3 months). The primary outcome measure was the left ventricular ejection fraction (LVEF). Results: There was no statistically significant difference in LVEF (U = 420.500, p value = 0.218) between the two groups. However, the yoga-practicing group showed significant reduction in depression (Cardiac Depression Scale [CDS], U = 71, p value = 0.0), anxiety (Hamilton Anxiety Rating Scale [HAM-A], U = 128, p value = 0.0), and a significant increase in quality of life (QOL) scores (Duke Activity Status Index [DASI], U = 146, p value = 0.0; and metabolic equivalents (METs), U = 136, p value = 0.0) at 3 months compared to control. Overall, the CAD patients practicing yoga showed a favorable profile compared to control individuals on CDS, HAM-A, DASI, and MET outcomes. Control and yoga practicing groups did not differ significantly in the lipid levels. Conclusion: This study indicated that the integration of yoga practice in a cardiac rehabilitation program is feasible and has no added benefit in improving the cardiac function. However, the addition of yoga to cardiac rehabilitation may be beneficial in reducing depression and anxiety and improving QOL in patients.

Noncommunicable diseases including coronary artery disease contribute to approximately 50% of global mortality. Pharmacological treatment alone may not be a panacea for such diseases since it may be associated with various other adverse effects. Hence, strategies such as Yoga involving healthy lifestyle and stress management are widely sought by the patient population. Materials and Methods: An electronic search of PubMed as a standard bibliographic database was performed through February 2015 using the keywords “Yoga” and “Cardiovascular.” Studies with Yoga as the independent variable and parameters related to cardiac health as the dependent variable were included and exclusion criteria were applied. Results: A total of 149 publications were identified which met the inclusion criteria for analysis. Of the total publications, 44% were clinical trials of which 19% were randomized controlled trials which may be categorized as high-quality ones. An upward trend in the overall research in this area is evident. Major work has been accomplished by researchers of the United States (38%) and India (29%). Conclusion: The survey indicates that the number of publications in the field of “Yoga” and “Cardiovascular” health has increased rapidly in the late years. Analysis comprising the nation/state helps define its status with regard to its counterparts and helps understand science priorities and disease control strategies in an effort to provide cost-effectiveness and quality control. There is a need for further high-quality studies in the field of “Yoga” and “Cardiovascular” diseases to validate the effects of Yoga on health parameters.
