Breast Arterial Calcification on a Screening Mammogram: A Potential Cardiovascular Risk Stratification Tool in Women

Area of Science:

• Cardiovascular Imaging
• Radiology
• Arterial Health

Background:

• Breast arterial calcification (BAC) is a common finding on mammograms, distinct from coronary artery disease (CAD) intimal calcification.
• BAC is increasingly recognized as a potential indicator for cardiovascular risk stratification.

Purpose of the Study:

• To review the current literature on the association between BAC and coronary artery calcification (CAC).
• To evaluate the controversial link between BAC and myocardial ischemia and angiographically proven CAD.
• To discuss the utility of BAC as a screening tool for CAD.

Main Methods:

• Systematic review of existing literature on BAC.
• Analysis of studies correlating BAC with CAC via coronary computed tomography.
• Examination of research on BAC's association with myocardial ischemia and invasive/CT-angiographic CAD.

Main Results:

• Evidence suggests a potential link between BAC and cardiovascular risk factors, including CAC.
• The association of BAC with myocardial ischemia and angiographically proven CAD is still debated.
• The role of BAC in mammography for CAD screening remains uncertain.

Conclusions:

• BAC shows promise as a cardiovascular risk marker, particularly in relation to CAC.
• Further research is needed to clarify the controversial associations between BAC and ischemic heart disease.
• The clinical utility of BAC for CAD screening requires more investigation and validation.
