While the Pooled Cohort Equations from the recent ACC/AHA Guideline on the Assessment of Cardiovascular Risk have over-estimated cardiovascular risk in multiple external cohorts, the reasons for the discrepancy are unclear. To determine whether increased use of statins over time, incident coronary revascularization procedures, or under-ascertainment of vascular events explain over-estimation of risk in a more contemporary population. 27,542 women aged 45-79 with complete ascertainment of plasma lipids and other risk factors from the Women's Health Study (WHS), a nationwide cohort of US women free of cardiovascular disease, cancer or other major illness at baseline in 1992-95. Women were followed for a median of 10 years. Atherosclerotic cardiovascular disease (ASCVD), defined as any myocardial infarction, any stroke, or death due to cardiovascular cause. 632 women experienced an ASCVD event over follow-up. The average predicted risk from the Pooled Cohort Equations was 3.6% over 10 years, compared to an actual observed risk of 2.2%. Predicted rates were 90% higher than the observed rates in the 0-<5% and 5-<7.5% risk groups and 40% higher in the 7.5-<10% and 10%+ risk groups. Rates of statin use and revascularizations increased over follow-up time and by risk group, and in sensitivity analyses, we estimated the hypothetical rates if no women were on statins or underwent revascularization procedures. After adjustment for intervention effects of statins and revascularization as well as hypothetical confounding by indication, predicted rates remained 80% higher than observed rates in the lower two risk groups and 30% higher in the upper two risk groups. Under-ascertainment is unlikely since follow-up rates in the WHS were 97%, and overall we would need 60% more events to match the numbers predicted using the Pooled Cohort Equations. Neither statin use, revascularization procedures, nor under-ascertainment of events explain the discrepancy between observed rates of ASCVD in the WHS and those predicted by the ACC/AHA Pooled Cohort Equations. Other explanations include changing patterns of risk within more contemporary populations.
