Breast screenings may be able to be used determine any heart risks.
Researchers looked at nearly 400 women who had a digital mammogram and a chest CT scan performed within one year of each other.
In the mammograms they saw any arterial build-up in the breast arteries and they saw coronary calcification in the CT scans.
When they compared the amount of calcification seen in the mammograms to the CT scans they found a striking relationship between the two.
Now while much more research will be needed before this is used in a patient setting the team says their findings show breast screening mammogram could play an important role in identifying women who may benefit from coronary artery disease prevention.
The results are scheduled for presentation during American Roentgen Ray Society in Toronto, Canada
