Mammograms May Provide Early Insight Into Cardiovascular Disease

Mammograms are primarily recognized for their role in detecting breast cancer, but emerging research suggests they may also serve as valuable tools for assessing heart health. Recent studies have indicated that breast arterial calcification (BAC), a condition that can be identified during routine mammogram screenings, may signal an increased risk for cardiovascular disease.

BAC refers to the accumulation of calcium deposits in the walls of small arteries within the breast, which can appear on mammograms as thin, white lines resembling a “tram-track.” While this condition is benign regarding breast tissue, it has been linked to a significantly heightened risk of heart-related issues. A 2022 study found that women displaying BAC were 51% more likely to develop heart disease or suffer a stroke compared to those without this condition.

Dr. Laxmi Mehta, a cardiologist at The Ohio State University Wexner Medical Center, explained that BAC is often associated with common cardiovascular risk factors such as diabetes, hypertension, and high cholesterol. Furthermore, BAC has been connected to a range of serious health conditions, including coronary artery disease, heart failure, strokes, and even cardiac death.

Experts believe that the correlation between BAC and cardiovascular disease may stem from shared risk factors that lead to vascular injury or metabolic stress. Dr. Cheng-Han Chen, an interventional cardiologist and medical director at MemorialCare Saddleback Medical Center, emphasized that the presence of calcium in breast arteries could suggest similar issues in the arteries of the heart and brain.

Heart disease remains the leading cause of death among women, accounting for one in every three female fatalities in the United States. In contrast, breast cancer claims the lives of approximately 1 in 39 women each year. Dr. Richard Reitherman, a radiologist at MemorialCare Breast Center, noted that cardiovascular disease often presents differently in premenopausal women, who may not exhibit typical symptoms like chest pain.

The identification of silent cardiovascular disease through mammograms could prove invaluable. Dr. Reitherman highlighted that the integration of BAC assessment into mammogram reporting could lead to early detection of cardiovascular risks, ultimately reducing mortality rates among younger women.

Despite the promising implications of BAC as a risk factor, it has historically been overlooked in clinical practice. Mammograms have primarily focused on breast cancer detection, and BAC findings were often deemed incidental and not clinically relevant. However, there is a growing movement among healthcare organizations to standardize the reporting of BAC in mammogram results.

Recent legislative changes, such as a new Maryland law requiring mammography centers to inform patients of detected BAC, represent a significant step forward. Dr. Reitherman anticipates that automated identification and reporting of BAC will become increasingly common, allowing for better risk evaluation and management.

Women are encouraged to inquire about BAC results after their mammograms, although not all radiologists currently report this information. Continued research is necessary to establish BAC as a routine predictor of cardiovascular risk, but its identification could aid in addressing heart health more proactively.

Incorporating BAC into routine healthcare practices could pave the way for improved outcomes not only in breast cancer but also in cardiovascular disease, highlighting the importance of a coordinated approach among healthcare providers to enhance women’s health overall.
