(LifeWire) -
Definition: Redness and swelling resulting from injury or infection. In the arteries, inflammation may hasten the formation of
plaque, which narrows or blocks the blood vessels.
Inflammation causes an increase in a substance known as C-reactive protein (CRP). It appears that CRP levels are an important indicator of
coronary artery
disease, stroke,
heart attack and survival after heart attack. They may signal the likelihood of recurrent cardiovascular events and stroke. The higher the level, the worse the prognosis.
CRP numbers may also predict the success of balloon angioplasty. A simple blood test is all that is needed to measure CRP levels.
