15 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. These were summed to create an overall plaque index.

22 Multivariate Regression Models of IMT- Effect of PCOS Models adjusted for age and BMI Models adjusted for age and BMI Risk factors explored include: Risk factors explored include:  PCOS, LDL, SBP, DBP, TRIG, W:H, insulin In the total group PCOS was not a significant predictor of IMT. SBP was only significant independent predictor. In the total group PCOS was not a significant predictor of IMT. SBP was only significant independent predictor. In women less than 45 years of age PCOS was not a significant predictor of IMT. SBP and DBP were significant independent predictors. In women less than 45 years of age PCOS was not a significant predictor of IMT. SBP and DBP were significant independent predictors.

23 Multivariate Regression Models of IMT- Effect of PCOS (cont.) In women 45 years or greater PCOS was a significant predictor of IMT, independent of age and BMI (p=.042). 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. With the addition of SBP, DBP or TRIG, the PCOS- IMT relationship remained borderline significant (p=.068-.088). With the addition of SBP, DBP or TRIG, the PCOS- IMT relationship remained borderline significant (p=.068-.088). The addition of insulin or W:H eliminated the significance of PCOS as an independent predictor of IMT.

24 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. There may be an independent effect of PCOS on IMT mediated by low peak estradiol levels or hormonal dysregulation. An increase in IMT is apparent even in thinner PCOS cases. An increase in IMT is apparent even in thinner PCOS cases. Arteriosclerosis, Thrombosis, and Vascular Biology, 2000;20:2414-2421

26 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.
