Yoga as an adjuvant therapy in heart failure patients on optimal medical management analysed using echocardiographic parameters

Background: Heart failure (HF) is a chronic complex disease that prevails as a prime cause of concern for healthcare sectors worldwide, with a concordant objective to improve the long-term prognosis. Analysis of the available literature is evidence that yoga therapy and basic lifestyle modifications have considerably augmented heart failure patients' quality of life and enhanced left ventricular ejection fraction and NYHA functional class. Aim: Our study aims to establish the long-term outcomes of yoga therapy to validate the addition of yoga therapy as a complementary treatment in managing HF.Methods: A prospective non-randomized study was conducted at a tertiary care center including seventy-five HF patients with NYHA class III or less who underwent coronary intervention, revascularization, or device therapy within the past six months to one year and continuing guideline-directed optimal medical therapy (GDMT). Thirty-five participants were part of the Interventional Group (IG), and forty were in the Non-Interventional Group (Non-IG). The IG received yoga therapy and GDMT, while the non-IG were only under standard GDMT. Echocardiographic parameters were compared at various follow-ups up to one year to see the impact of Yoga therapy on HF patients. Results: A total of 75 heart failure patients, including 61 males and 14 females. The IG and non-IG had 35 subjects (31 males and 4 females) and 40 subjects (30 males and 10 females), respectively. Echocardiographic parameters were observed to compare the IG and Non-IG groups, and those did not demonstrate any significant difference between the two groups (p-value > 0.05). But, the echocardiographic parameters of the IG and non-IG from baseline to six months and one year showed a significant improvement (p-value of <0.05). The functional outcome (NYHA classes) was assessed after follow-up, and a p-value <0.05 showed a substantial improvement in the IG.Conclusion: Yoga therapy results in better prognosis, functional outcome, and left ventricular performance in HF patients with NYHA III or less. Hence this investigation has attempted to justify its importance as adjuvant/ complimentary treatment for HF patients.
