A Study to Evaluate the Effect of a Combined Approach of Yoga and Diet in High-risk Cardiovascular Subjects.

Background: Cardiovascular disease (CVD) is a group of disorders of the heart and blood vessels, including coronary heart disease, cerebrovascular disease, rheumatic heart disease, peripheral artery disease, congenital heart disease, deep vein thrombosis, and pulmonary embolism.

Aim: The aim of this study was to assess cardiovascular risk factors and evaluate the effectiveness of combined approach of yoga and diet in reducing cardiovascular risk factors among high-risk subjects.

Materials and methods: This interventional study was conducted at RUHS College of Medical Sciences and Associated Hospitals, Jaipur, on the high-risk population of either sex in the age group of 40-70 years. QRISK3 web calculator was used as the method of measurement for outcome of interest. The combined approach of yoga intervention includes yogic asanas and pranayamas and dietary modification.

Results: This study compared physiological parameters (blood pressure) and biochemical parameters (fasting blood sugar, glycosylated hemoglobin, lipid profile) at baseline, three months and six months after yoga and diet intervention in participants who were at high-risk of cardiovascular disease development in future and were found to be having significantly decreased systolic blood pressure (P=0.000), fasting blood glucose (P=0.000), glycosylated hemoglobin (HbA1C) (P=0.011), total cholesterol-high density lipoprotein ratio (P=0.000), low density lipoprotein (P=0.009), triglyceride (P=0.034), and QRISK3 Score (P=0.000) after combined approach of yoga and diet.

Conclusions: This study concluded that the short-term combined approach of yoga-based life-style intervention and diet reduced cardiovascular risk factors in subjects at high-risk of developing cardiovascular disease.
