A coronary calcium score comes from a quick CT scan of your heart, with no injection. It counts the calcium in the walls of your heart arteries, which is a sign of plaque that has hardened, and turns it into a single number.
It is an established test for sharpening heart risk in adults whose risk is unclear from cholesterol and blood pressure alone, and the result can help you and a physician decide about treatment. It uses a low dose of radiation and sees only hardened plaque, not the softer kind.

Coronary Calcium Score: common questions
Which clinics in Houston list coronary calcium scoring?
3 in our Houston guide: Memorial Longevity Clinic, Prosper Medicine and Maximum Resolution Imaging Center.
How do I prepare?
Many centers ask you to skip food, drinks and caffeine for a few hours beforehand. Follow the instructions you are given.
What does a score of zero mean?
That the scan found no hardened plaque. It does not see softer plaque, so it is one input to your heart risk rather than the whole picture.
Calcium score or CT angiogram?
A calcium score is quicker, uses no injection and sees hardened plaque. A CT angiogram uses contrast dye and also shows softer plaque. They answer different questions.
