TLDR People with polycystic ovary syndrome may have a higher risk of heart problems due to abnormal nervous system control of their heart and blood pressure.
In the 2008 study, researchers compared the cardiovascular autonomic neural control between 26 untreated PCOS patients and 24 healthy controls, finding significant differences indicative of altered autonomic function in the PCOS group. The PCOS patients showed a lower heart rate recovery at 1 minute post-exercise and higher systolic blood pressure at peak exercise and during recovery, suggesting reduced parasympathetic activity and heightened sympathetic response. Additionally, heart rate variability measures were significantly lower in the PCOS patients. These results imply that PCOS may be associated with an increased risk of developing cardiovascular issues due to abnormal autonomic regulation.
