Sympathovagal imbalance in prehypertension status

Abstract

Background: Heart rate variability (HRV) had been promoted for longer than half a century to monitor the activity of autonomic nerve systems. Previous studies have not clarified the relationship between HRV and prehypertension (pre-HTN) status compared with the normal group. We aimed to figure out the optimal model or cutoff point for predicting the possible pre-HTN status. Patients and Methods: We retrospectively collected and reviewed 2586 Asian people who had joined annual physical examination in Tri-Service General Hospital at 2013. The patient profiles such as age, gender, body height, body weight, body weight index, waist circumferences, and serological biochemistry data were analyzed and correlated with HRV parameter. Results: A total number of 909 patients were enrolled in our study. The physical stress index (PSI) owed a small but most significant Spearman's relation coefficient (r = 0.118, P58.4. Early intervention to these participants may decrease cardiovascular events in the coming future
