Coronary artery disease (CAD) continues to be the leading cause of morbidity and mortality in women, contributing to about 20%, or nearly 400,000, of female deaths annually in the United States. Despite their significant burden from CAD, women have been traditionally underrepresented in trials, and therefore, there is still much to be studied regarding the sex-based variations that have been reported regarding the pathophysiology, clinical presentation, efficacy of diagnostic workup, and response to therapy in CAD. Previous studies have reported that breast arterial calcifications, commonly found incidentally on screening mammography, may be associated with risk of CAD; however, there are currently no specific guidelines concerning reporting and quantification practices, as well as further workup recommendations for patients who are found to have vascular calcifications. Thus, the question remains whether breast arterial calcifications can serve as a sex-specific marker for CAD, and whether there is enough evidence to support the use of mammography as a screening tool for CAD in women. In this review, we will summarize the current understanding of cardiovascular disease in women, the existing literature regarding breast arterial calcifications and current reporting practices, and the association of vascular calcifications with CAD risk; based on the collected evidence, we will make a recommendation whether screening mammography and breast arterial calcifications should be used to assess CAD risk, and if so, what additional workup, if any, we recommend in women found to have breast arterial calcifications on imaging.
