Plaque Indexed was also scored: Plaque was defined as a distinct area protruding into the vessel lumen with at least 50% or > thickness than the surrounding area. Plaque was defined as a distinct area protruding into the vessel lumen with at least 50% or > thickness than the surrounding area. Scoring was as follows: 0= no stenosis, 1 = small stenosis 50% or multiples with at 1 medium stenosis. Scoring was as follows: 0= no stenosis, 1 = small stenosis 50% or multiples with at 1 medium stenosis. These were summed to create an overall plaque index.

In women 45 years or greater PCOS was a significant predictor of IMT, independent of age and BMI (p=.042). With the addition of LDL, this relationship became more significant (p=.024). Both LDL and PCOS exerted independent significant effects. With the addition of LDL, this relationship became more significant (p=.024). Both LDL and PCOS exerted independent significant effects.

Regression Summary: Fasting insulin and W:H appear to attenuate the relationship of PCOS and IMT, suggesting that at least part of the PCOS-IMT association in middle aged PCOS women may be driven by central obesity and hyperinsulinemia. Fasting insulin and W:H appear to attenuate the relationship of PCOS and IMT, suggesting that at least part of the PCOS-IMT association in middle aged PCOS women may be driven by central obesity and hyperinsulinemia. There may be an independent effect of PCOS on IMT mediated by low peak estradiol levels or hormonal dysregulation.

Conclusions : The epidemiologic studies to date have been mainly consistent in their findings of increases in cardiovascular risk factors in women with PCOS. These have however been largely cross-sectional. The epidemiologic studies to date have been mainly consistent in their findings of increases in cardiovascular risk factors in women with PCOS. These have however been largely cross-sectional. Subclinical measures have shown increases in women >45 and this would imply a common source long incubation “latency” effect of increases in CHD RF in younger PCOS women over time. Subclinical measures have shown increases in women >45 and this would imply a common source long incubation “latency” effect of increases in CHD RF in younger PCOS women over time. However, a prospective study following a larger cohort of women with PCOS is needed to determine if there is a true increased risk of CHD events.
