The potential impact of mammographic breast arterial calcification on physician practices in a primary care setting

Area of Science:

• Radiology
• Cardiology
• Primary Care Medicine

Background:

• Breast arterial calcification (BAC) is a common finding on mammograms.
• The clinical significance of BAC in primary care settings requires further investigation.
• Assessing BAC may offer insights into cardiovascular risk beyond traditional metrics.

Purpose of the Study:

• To determine the prevalence of breast arterial calcification (BAC) in a primary care population.
• To evaluate the potential of BAC as a marker for guiding cardiovascular workup.
• To compare characteristics of women with and without BAC.

Main Methods:

• Retrospective review of 282 consecutive mammograms by a radiologist.
• Comparison of demographic and clinical characteristics between BAC-positive and BAC-negative women.
• Statistical analysis to assess the association between BAC and cardiovascular risk factors.

Main Results:

• BAC was identified in 34% of women.
• BAC-positive women were older and had higher 10-year cardiac risk, hypertension, and coronary artery disease.
• BAC-positive women also showed increased use of statins and aspirin.
• Approximately 37% of BAC-positive women were identified as potential candidates for further cardiac testing.

Conclusions:

• Mammography can detect BAC, a marker associated with increased cardiovascular risk.
• BAC may help identify individuals with low traditional cardiovascular risk who could benefit from further cardiac evaluation.
• Integrating BAC assessment into routine mammography could enhance cardiovascular risk stratification in primary care.
