Background and Objective: It is well known that a hall mark of heart failure is adverse changes in autonomic function. Elevated blood pressure is a powerful predictor of congestive heart failure and other cardiovascular disease outcomes. In this study, we planned to examine the effects of a 12 week yoga therapy on blood pressure, heart rate, heart rate variability, and rate pressure product (RPP). Methods: Out of 130 heart failure patients recruited for the study, 65 patients were randomly selected to receive 12 week yoga therapy along with standard medical therapy (yoga group). Other patients (n=65) received only standard medical therapy (control group). Heart rate, blood pressure, cardiac autonomic function (by short-term heart-rate variability analysis) and myocardial oxygen consumption (by RPP) were assessed before and after 12 weeks. In the yoga group, 44 patients and in the control group, 48 patients completed the study. results: There was a significant decrease in heart rate, blood pressure and RPP in yoga group compared to control group. Also, LFnu and LF-HF ratio decreased significantly and HFnu increased significantly in yoga group compared to control group. conclusion: Twelve-week yoga therapy significantly improved the parasympathetic activity and decreased the sympathetic activity in heart failure patients (NYHA I&II).

Slow, deep, pranayama - based breathing training has been shown to be effective in reducing blood pressure (BP). The present study was undertaken to determine immediate effects of performing pranava pranayama on cardiovascular parameters in hypertensive patients. 29 hypertensive patients who were on medical treatment and also attending yoga sessions were recruited for the present study. Supine heart rate (HR) and BP were recorded before and after performance of pranava pranayama for five minutes. Post intervention statistical analysis revealed a significant (P<0.05) reduction in systolic pressure (SP) and a more significant (P<0.01) reduction in HR, pulse pressure and double product (Do P). The reduction in rate-pressure product (RPP) was highly significant (P<0.001). Pranava pranayama is effective in reducing HR and SP in hypertensive patients within five minutes of the practice. This may be due to a normalization of autonomic cardiovascular rhythms as a result of increased vagal modulation and/or decreased sympathetic activity and improved baroreflex sensitivity along with an augmentation of endogenous nitric oxide production. Our findings have potential therapeutic applications in day-to-day as well as clinical situations where blood pressure needs to be brought down at the earliest. The significant fall in RPP and Do P signifies a reduction in oxygen consumption and work done by the heart. It is concluded that pranava pranayama, a simple and cost effective technique can be used in the management of hypertensive patients in addition to the regular medical management. Further studies are required to enable a deeper understanding of the mechanisms involved and its usefulness in the long- term management of hypertension. Source

Yogic practices may aid in the prevention and management of Hypertension (HT) and reduce cardiovascular complications in the population. The present study was undertaken to evaluate the effects of a comprehensive eight week yoga therapy programme on anthropometric, cardiovascular, biochemical parameters and wellness scores in patients of essential HT. 15 patients receiving standard medical treatment for essential HT were recruited and anthropometric, cardiovascular and biochemical investigations were done before and after a comprehensive yoga therapy programme comprising of three times a week sessions for 8 weeks. A post intervention, retrospective wellness questionnaire was used to evaluate the comparative feelings of the patients after the therapy programme. There was a statistically significant decrease in weight, BMI and all resting cardiovascular parameters such as heart rate and blood pressure indices. Total cholesterol (TC), triglyceride (TG), low density (LDL) and very low density (VLDL) lipoproteins reduced significantly while high density (HDL) lipoprotein increased significantly. All the cholesterol based ratios such as TC/HDL, LDL/HDL and showed healthy improvements. Post intervention overall wellness scores of the participants indicated that 9% attained complete relief and total satisfaction after the therapy programme while 29% were much better than before. 36% were better than before while 25% had no change in their condition. The main strength of the present study is excellent compliance and regularity of yoga practice by our participants both during directly supervised sessions and at home. Very few yoga studies have reported such excellent compliance and hence our study stands out as a special case. Hence, the all round benefits obtained in our study can be attributed to the dedicated and regular practice of the comprehensive yoga therapy programme that reports a significant improvement in anthropometric and cardiovascular parameters coupled with healthy lipid profile changes in patients of essential HT. It is concluded that a comprehensive yoga therapy programme has potential to enhance the beneficial effects of standard medical management of essential HT and can be used as an effective complementary or integrative therapy programme.
