The association of hysterectomy with increased coronary risk is controversial, and previous studies have reached differing conclusions as to whether the excess risk is confined to women who have also undergone bilateral oophorectomy. This analysis uses the Framingham algorithm to evaluate the hypothesis that hysterectomy with or without ovarian preservation is associated with increased coronary risk, using a cross-sectional analysis of baseline data from 1,501 participants of the Women’s Health Initiative. Framingham risk scores, derived from the algorithm in the National Cholesterol Education Program Adult Treatment Panel III guidelines, which include age, smoking, systolic blood pressure, total and high-density lipoprotein cholesterol, were determined in a subgroup of Women’s Health Initiative participants with measured plasma lipids and known ovariectomy status. Women with hysterectomy had fewer years of education than those without hysterectomy (30% with college degree vs 41%, p <0.0001) and higher body mass index (29 vs 28 kg/m², p <0.0001), consumed less alcohol, exercised less, and had a higher Framingham risk of myocardial infarction or coronary death (46% vs 41% with 10-year risk ≥4%, p = 0.04). In multivariate analysis, hysterectomy with bilateral oophorectomy was an independent predictor of Framingham risk (p = 0.04), whereas hysterectomy with ovarian preservation was not.
