What is a heart CT scan?
Also called a calcium-score screening heart scan, it's used to find calcium deposits in the plaque of people with heart disease. It's the most effective way to spot atherosclerosis before symptoms develop.
The more coronary calcium you have, the more coronary atherosclerosis you have. That gives you a higher chance of heart and blood vessel problems in the future.
Some kinds of coronary disease don’t show up in a CT scan, so this test can't completely predict things like a heart attack.
