Abstract
Aim: Bilirubin is a final product of heme metabolism
and also has antioxidant properties. But there is no
information on the effect of bilirubin in the
pathogenesis of in Polycystic Ovary Syndrome
(PCOS). The goal of the present study was to
investigate the relationship between bilirubin levels,
PCOS and heart rate recovery (HRR).
Material and Methods: Subjects were included in
this study from our center’s Department of
Gynecology & Obstetrics between March 2012 and
May 2013. Serum bilirubin levels and other blood
parameters in at least 12-hour fasting states were
determined. Exercise stress test was performed on all
patients and control participants
Results: Thirty four patients with a diagnosis of
PCOS aged younger than 40 year and twenty seven
healthy women matched by age, BMI, heart rate and
blood pressure were included in the study. Total
bilirubin levels in PCOS group were significantly
lower than the control group. The HRR was
significantly decreased in women with PCOS
compared the control group. In the Pearson
correlation test, HRR was significantly correlated
with homeostasis model assessment insulin resistance
(HOMA-IR) index and bilirubin levels.
Conclusions: The bilirubin levels may affect HRR in
PCOS patients. Therefore, in the treatment of PCOS
patients, oxidative stress and its harmful effects
should be considered.
