Three Tests, Three Different Questions

A stress test asks whether blood flow to the heart is significantly limited right now, which usually requires an advanced blockage. A coronary calcium scan asks how much calcified plaque has already formed. CIMT ultrasound asks an earlier question: is the arterial wall itself beginning to change, including soft plaque that has not yet calcified.

Why Earlier Detection Favors CIMT

Because CIMT can detect arterial wall thickening and soft plaque before calcification occurs, it is often informative for adults in their 30s to 50s whose calcium score would still read zero. It is also radiation-free and repeatable, which makes it useful for tracking change over time.

The Right Test Depends on the Person

None of these tests replaces the others, and the right choice depends on your age, risk factors, history, and prior findings. A clinician who understands your full picture can recommend the sequence of testing that answers the most important question for you first.
