Abstract

Early detection of cardiovascular disease remains one of the most significant challenges in modern medicine. Despite major advances in preventive cardiology, cardiovascular disease (CVD) continues to be the leading cause of death among women worldwide. Recent breakthroughs in Artificial Intelligence (AI) in healthcare have enabled the extraction of novel biomarkers from existing medical imaging datasets. One such emerging biomarker is Breast Arterial Calcification (BAC) detected in routine mammography.

Recent studies demonstrate that AI-calculated BAC on mammograms predicts cardiovascular disease in women with remarkable accuracy. Using advanced deep learning algorithms, automated systems can quantify arterial calcification in mammograms and transform breast cancer screening images into powerful cardiovascular risk assessment tools.

This column explores the clinical significance, AI methodology, predictive modeling, and future healthcare implications of AI-based BAC analysis. The article also discusses how this technology may reshape preventive cardiology, reduce healthcare costs, and enable population-scale cardiovascular screening using existing imaging infrastructure.

1. Introduction

Cardiovascular disease (CVD) remains the leading cause of mortality among women worldwide. According to global health statistics, more women die from cardiovascular complications than from all cancers combined. Despite this alarming statistic, cardiovascular risk assessment in women is often delayed or underdiagnosed.

Traditional screening methods for CVD include:

• Lipid profile testing
• Blood pressure monitoring
• Coronary artery calcium (CAC) CT scans
• Electrocardiography (ECG)

However, these methods require dedicated testing and are not routinely performed in asymptomatic individuals.

Meanwhile, millions of women undergo routine mammography screening every year for breast cancer detection. These images frequently contain vascular calcifications within breast arteries, a phenomenon known as Breast Arterial Calcification.

Historically, BAC was considered an incidental radiological finding with little clinical relevance. However, recent advances in Artificial Intelligence and deep learning have revealed that BAC strongly correlates with Cardiovascular Disease, including:

• Coronary artery disease
• Stroke
• Peripheral vascular disease
• Myocardial infarction

This discovery has triggered global interest in AI-powered mammography analysis for cardiovascular risk prediction.

2. Breast Arterial Calcification: An Underutilized Biomarker

2.1 Pathophysiology of BAC

Breast arterial calcification represents medial arterial calcification, distinct from the intimal calcification seen in coronary artery disease.

It is frequently associated with:

• Aging
• Diabetes mellitus
• Chronic kidney disease
• Hypertension

Unlike atherosclerotic plaque calcification, BAC reflects systemic vascular stiffness, which is a major predictor of cardiovascular events.

Clinical Insight

Studies show that women with significant BAC have:

Risk Factor	Relative Increase
Coronary artery disease	2–4×
Stroke	1.5–2×
Cardiovascular mortality	2×

This makes BAC a powerful imaging biomarker for cardiovascular risk.

2.2 Why Mammograms Are Ideal for BAC Detection

Mammography is one of the most widely performed imaging tests globally.

Key advantages include:

Feature	Benefit
Routine screening	Large population coverage
High spatial resolution	Detects small vascular calcifications
Existing imaging infrastructure	No additional testing cost
Large historical datasets	Ideal for AI training

Therefore, integrating AI mammography analysis into existing radiology workflows creates an unprecedented opportunity for population-scale cardiovascular screening.

3.1 AI Workflow for BAC Quantification

The AI pipeline typically follows these steps:

Step 1 – Mammogram Image Acquisition

Digital mammography images are obtained during routine breast cancer screening.

Step 2 – Image Preprocessing

Step 4 – Calcification Detection

Algorithms detect calcified plaques within arterial walls.

Step 5 – BAC Score Calculation

AI systems quantify calcification using a BAC severity score.
