These scans look at your arteries directly. A calcium score shows hardened plaque, and a CT angiogram shows softer plaque and narrowing. They help most when your risk is borderline and a scan could change your treatment. If your risk is clearly low or clearly high, they usually add little.
The scans, in plain English
Blood tests are like checking the weather forecast. A heart scan is like looking out the window: it shows what's actually there right now.
Calcium score
A quick CT scan of your heart with a low dose of radiation. You get a number: zero means no hardened plaque was found, and higher means more buildup.
For: People whose risk is borderline and a decision is closeCoronary CT angiogram
A dye goes in through an IV so the scan can show soft and hard plaque and any narrowing. Some clinics add software that measures the plaque.
For: Usually when a doctor thinks more detail would change the planCarotid ultrasound
Sound waves look at the arteries in your neck for plaque or thickening, with no radiation. Experts advise against using it to screen people who have no symptoms.
For: When a doctor has a specific reason to lookPulse wave velocity
Measures how fast your pulse travels along your arteries. Stiffer arteries carry it faster. Quick and painless, but it is mostly a research measure for now.
