Associations between the severity of metabolic syndrome and cardiovascular autonomic function in a Chinese population.

摘要: Background: The purpose of this study was to evaluate associations between the severity metabolic syndrome (MetS) and cardiovascular autonomic function (CAF) in a Chinese population. Methods materials: We conducted large-scale community-based cross-sectional estimate MetS CAF included 2119 subjects. defined accordance with criteria published by International Diabetes Federation. assessed via heart rate variability (HRV) baroreflex sensitivity (BRS). Univariate multivariate linear regression (MLR) analyses were undertaken statistical significance investigated. Results: Three HRV components differed significantly groups regard scores; total power (TP), low frequency (LF), high (HF), BRS also (p<0.05 for each component). MLR analysis revealed that insulin resistance (IR) associated (β=-0.08~−0.16, p<0.05 both). Fasting plasma glucose (FPG) blood pressure (BP) negatively correlated favorable outcomes (β=−0.042~−0.119, Conclusions: In study, IR independently CAF. Two components, FPG BP, Also, decreased increased scores.
