Breast arterial calcifications (BACs) found on screening mammography and their association with cardiovascular disease.

Objective: Breast arterial calcifications (BACs) are common but unreported findings on screening mammograms. This study correlated mammographically detected BACs with coronary artery disease (CAD) risk factors and a history of atherosclerotic cardiovascular disease (ASCVD), estimating the relative risk of ASCVD in patients with BACs.

Design: Women arriving for breast cancer screening mammography gave their consent to complete a questionnaire and to allow their mammograms to be analyzed independently for the presence of BACs by certified radiologists, who were blinded to the results of the questionnaire.

Hormonal therapy is associated with a lower prevalence of breast arterial calcification on mammography.

Objective: To bring further understanding to the relationship between hormonal therapy (HT) and breast arterial calcification (BAC).

Methods: Of women arriving for breast cancer screening mammography, 1995 consented to complete a survey and have their mammograms analyzed for the presence of BAC. The survey assessed HT use and major risk factors for CAD.
