Interesting study looked PCOS and the sympathetic vagal system and cardiovascular disease risk. They found that those with PCOS were found to have sympathovagal imbalance and decreased HRV.  Low HRV has been clearly associated with increased cardiovascular disease.  They also found insulin resistance and dyslipidemia to be associated with sympthovagal imbalance and cardiovascular risk as well.

antidepressants shown to reduce heart rate variability (HRV) and an increased heart rate (HR), both of which increase cardiovascular disease (CVD).

Review of benefits of Heart Rate Variability testing (HRV).

HRV application validated

HRV useful in following and intervention in those with post concussion syndrome.

Chronic stress increases cardiovascular disease.  Of note, chronic stress reduces eNOS activity and NO bioavailability, increased lipid oxidation (oxLDL) via a reduction in antioxidant protection, increased pro-inflammatory cytokines, increased thrombosis and clotting risk, increased blood pressure and reduced HRV.

decreased heart rate variability associated with increased CVD and mortality

High repetition, low weight is associated with improved Heart rate variability, muscle strength and endurance in non-healthy-CAD patients.
