Cholesterol-rich buildup that can narrow arteries and reduce blood flow.

What it is

Atherosclerotic plaque is buildup inside artery walls that can narrow or block blood flow.[1,2]

Why it matters

NHLBI describes coronary heart disease as narrowing from fatty plaque deposits that limit oxygen-rich blood to the heart muscle.[1]

What it affects

  • Plaque context connects lipid tests, coronary imaging, ischemia, heart attack, and stroke risk discussions.[2,1]

Interpretation traps

  • A cholesterol result alone is not a full plaque map or personal event prediction.[2]
