In a recently published study, Jeon and colleagues report on a retrospective analysis of coronary-artery calcium scores in 436 postmenopausal women who underwent computed tomography (CT) scanning in the hospital’s Health Promotion Center [1]. Serum estradiol, lipids and bone mineral densities were also obtained. In women not receiving hormonal therapy, the women were divided into those with serum estradiol levels < 20 pg/ml and those with estradiol levels ≥ 20 pg/ml; the women were also divided into those with coronary artery calcium scores < 100 and those with scores ≥ 100. Women with lower estradiol levels (< 20 pg/ml) had significantly higher calcium scores (p < 0.05). After adjusting for multiple variables by weighted logistic regression, women with higher estradiol levels had a reduced chance of having a higher coronary calcium score (adjusted odds ratio 0.25; 95% confidence interval 0.07–0.86; p = 0.03).
