Overview

Suggests subclinical autonomic dysfunction in PCOS; hypothesis-generating for inflammation-mediated mechanisms and needs longitudinal validation.

Structured PICO

Is polycystic ovary syndrome associated with altered heart rate variability compared to healthy ovulatory women?

P
Population
46 women, comprising 23 volunteers with polycystic ovary syndrome (PCOS) and 23 age-matched healthy ovulatory controls.
C
Comparator
Age-matched healthy ovulatory women
O
Outcome
Heart rate variability (HRV) indexes in the time domain (SDNN and rMSSD) and frequency domain (low frequency-LF and high frequency-HF)surrogate

Polycystic ovary syndrome is associated with reduced heart rate variability and altered autonomic modulation, which appears to be driven in part by increased weight and systemic inflammation.
