OBJECTIVE: To compare the prevalence of subclinical atherosclerosis between postmenopausal women and men of similar age early after the onset of menopause. METHODS: In the first part of this cross-sectional study 186 non-diabetic young postmenopausal women (n = 101, menopausal age ≤ 10 years) and men (n = 85) aged 40-60 years without overt CVD were consecutively recruited from the outpatients clinics of an academic hospital. Subclinical carotid atherosclerosis was assessed by high-resolution ultrasonography. The presence of carotid atherosclerosis was defined as either increased carotid intima-media thickness (IMT>0.9 mm) and/or the presence of plaques. In the second part, 1:1 matching for age and traditional risk factors (hyperlipidemia, smoking, hypertension and BMI) was performed between men and women of this cohort resulting in a matched sub-sample of 76 subjects. RESULTS: By multivariate analysis, gender was not an independent determinant of any measure of carotid atherosclerosis. In the matched sub-sample, carotid IMT and the number of segments with atherosclerosis did not significantly differ between women and men (0.734 ± 0.119 mm and 1.47 ± 1.6 versus 0.717 ± 0.138 mm and 1.47 ± 1.5, p = 0.575 and p = 0.999, respectively). Also, the prevalence of increased IMT (60.5% in both genders), carotid plaques and subclinical atherosclerosis (31.6% and 63.2% versus 28.9% and 65.8%, p = 0.803 and p = 0.811, respectively) was similar between men and women. CONCLUSIONS: The prevalence and severity of carotid atherosclerosis was similar between men and young postmenopausal women matched for traditional risk factors. Whether these women may be better risk stratified irrespective of gender should be further assessed in prospective studies.
