AI Algorithm Predicts Women’s Cardiovascular Risk from Mammograms
Table of Contents
A groundbreaking new artificial intelligence (AI) algorithm developed by Australian researchers can predict a woman’s risk of developing major cardiovascular disease (CVD) over the next 10 years, using only data from routine mammograms and the patient’s age. This offers a potentially revolutionary, non-invasive method for early risk assessment, especially valuable given the often-undervalued cardiovascular risk in women.
At a Glance
- What: an AI algorithm predicting 10-year cardiovascular disease risk.
- Where: Developed by researchers at the University of Sydney, Australia; tested on data from Victoria, Australia.
- When: Research published in September 2025 in the journal Heart (data collected 2009-2020).
- Why it Matters: Cardiovascular disease is a leading cause of death for women, and this offers a new, accessible screening method.
- What’s Next: Further validation studies and potential integration into routine mammography screening programs.
What happened? The Research Explained
Researchers at the University of Sydney have created a deep learning algorithm that analyzes internal breast structures and characteristics visible in mammograms, combined with the patient’s age, to assess their cardiovascular risk. The study, published in the journal Heart, involved analyzing data from 49,196 women aged 59 on average, participating in the Lifepool cohort register in Victoria, Australia between 2009 and 2020.
The algorithm doesn’t require additional medical records or patient history (anamnesis), making it a potentially streamlined and cost-effective screening tool. This is a important advantage, as traditional cardiovascular risk assessments often rely on extensive patient questionnaires and blood tests.
Why This matters: The Link Between Breast Health and Heart Health
The connection between breast health and cardiovascular health isn’t widely known, but research suggests a strong correlation. Mammary arterial calcification and breast tissue density – both visible on mammograms – have been linked to increased cardiovascular risk. Scientists beleive this is due to shared underlying factors, such as inflammation and vascular changes.

This research is a compelling example of how we can leverage existing medical imaging data for broader health assessments. The fact that the algorithm doesn’t require additional data collection is a major benefit, potentially increasing screening rates and enabling earlier intervention. However,it’s crucial to remember that this is a risk prediction tool,not a diagnosis. Further research is needed to determine the optimal way to integrate this technology into clinical practice and to understand its performance across diverse populations.
How the AI Algorithm works
The AI algorithm utilizes deep learning, a subset of machine learning, to identify subtle patterns in mammographic images that are indicative of cardiovascular risk. The algorithm was trained on a large dataset of mammograms and corresponding cardiovascular health data, allowing it to learn the complex relationships between breast characteristics and heart health. Specifically, the algorithm analyzes:
- Mammary Arterial Calcification: The presence and extent of calcium deposits in breast arteries.
- Breast Tissue Density: The proportion of dense tissue versus fatty tissue in the breast.
- Breast Structure: Subtle variations in the architecture of the breast tissue.
- Age: A critical factor in cardiovascular risk assessment.
Who is Affected?
This research has the potential to impact millions of women worldwide. Cardiovascular disease remains the leading
