Autonomic functions in metabolic syndrome in Indian subpopulation using heart rate variability - A pilot study

Abstract

Background: The global industrialization and sedentary lifestyle has led to rise in obesity, hypertension, and diabetes which is associated with increased prevalence of metabolic syndrome (MS) all over the world, with rising trend among the younger population. Individuals with MS are at a higher risk of impaired cardiovascular autonomic function. Aim and Objective: Our study aims to understand the relationship between the MS and autonomic functions in order to improvise the wellbeing of the people who are at either risk of developing or are suffering from MS and promote healthy lifestyle. Materials and Methods: Heart rate variability (HRV) was recorded in 10 participants with MS. The HRV analysis included estimation of time domain parameters and frequency domain parameters, total power and low frequency/high frequency (LF/HF). Results: The HRV parameters showed a decrease in value along with a high LF/HF ratio in the study participants. Conclusion: The study shows that MS significantly leads to dysfunction of autonomic nervous system.
