Why can’t/don’t doctors regularly check to see if your arteries are majorly clogged?

Question

I often hear stories of a guy who has a heart attack and come to find out that 95% of a major blood vessel to the heart was clogged.

How is this not picked up earlier during normal exams? Why isn’t it?

Can’t they do radiation shots to see where the blood flows or whatever?

We don’t have the personnel or material resources to do that for everyone, among other reasons.
