The tests, in plain English
Start with the basics: blood pressure, a cholesterol panel, blood sugar and your family history. They do most of the work. ApoB and a one-time Lp(a) test add useful detail for some people, and a heart scan helps most when your risk sits in the middle and a decision could go either way.
Think of your arteries like the pipes in a house. Blood tests show how much is flowing through that could clog them. A heart scan looks inside the pipes for buildup that's already there.
Blood pressure
The biggest single number for heart risk.
Cholesterol panel
It shows how much cholesterol and fat are in your blood, which is what slowly builds up as plaque.
ApoB
Counts the particles that actually get stuck in artery walls.
Lp(a)
An inherited marker that raises heart risk on its own, even when your other numbers look healthy.
Calcium score
A quick CT scan that shows hardened plaque already sitting in the heart's arteries.
Coronary CT angiogram
A more detailed scan that shows soft and hard plaque, plus any narrowing.
