Key result
Larger waist circumference in MetS is moderately associated with higher sympathetic and lower parasympathetic HRV.
Why the study?
Metabolic Syndrome poses significant cardiovascular risk often assessed through HRV, but a suitable anthropometric or biochemical proxy was needed for resource-intensive HRV in primary and community healthcare setups.
Does waist circumference correlate with cardiac autonomic profile assessed by Heart Rate Variability in patients with Metabolic Syndrome?
Cross-Sectional (n=174)
No
Does waist circumference correlate with cardiac autonomic profile assessed by Heart Rate Variability in patients with Metabolic Syndrome?
Waist circumference may serve as a simple, non-invasive proxy for assessing cardiac autonomic dysfunction in patients with metabolic syndrome.
Answers are grounded in this paper and cite their sources.
Waist circumference was associated with sympathetic HRV predominance in metabolic syndrome; hypothesis-generating correlation leaves open proxy utility.
Introduction - Metabolic Syndrome (MetS), a global epidemic on the rise, affects about one-third of the world’s population. MetS poses significant cardiovascular risk often assessed through the cardiac autonomic function test Heart Rate Variability (HRV). This study attempts to identify a suitable anthropometric or biochemical proxy for resource-intensive HRV to assess cardiac autonomic profile in primary and community healthcare setups. Methodology - This cross-section study assessed relevant anthropometric, biochemical, and HRV parameters of 174 patients recently diagnosed with MetS. Results - Waist circumference (WC) had a significant (p<0.05) moderate to strong (r=0.49) positive correlation with sympathetic predominant HRV parameters - LFnu and LF/HF ratio. Parasympathetically modulated HRV parameters like Average RR (r=-0.17), rMSSD (r=-0.23), and HF (r=-0.49) had a significant (p<0.05) negative correlation with WC. Conclusion - The study identifies WC as a suitable indicator for cardiac autonomic profile in patients with MetS and by extension of cardiovascular posed by the disease.

Bhasi et al. (2023) conducted a cross-sectional in Metabolic Syndrome (n=174). Waist Circumference was evaluated on Correlation between waist circumference and LFnu (sympathetic HRV parameter) (r=0.49, p=<0.001). Waist circumference had a significant moderate positive correlation (r=0.49) with sympathetic HRV parameters and a negative correlation (r=-0.49) with parasympathetic parameters in Metabolic Syndrome.
