Coronary artery calcium scoring

Coronary calcium scans

This test looks for calcification in the coronary arteries, which can then be measured, scored and compared against other patients of a similar age and gender

About calcium scoring

Calcium in the heart arteries (coronary calcium) occurs when there is a build-up of plaque narrowing the arteries. This can be easily detected using a specific CT scan and then measured using a computer.

The calcium score is the measurement of the build-up and is used to detect early heart disease or to predict the risk of developing future cardiac problems and prevent heart attacks. The early detection of disease before symptoms develop enables early preventative measures and lifestyle changes to be prescribed, helping to reduce the risk of future damage to the heart.
