High Sensitivity C-Reactive Protein (HS-CRP)

C-reactive protein is a protein your liver produces as part of your immune system response to injury or infection and may indicate whether you’re likely to have a heart attack. It’s also produced by muscle cells within the coronary arteries. CRP is a nonspecific sign of inflammation, which means it may not be clear what’s causing the inflammation. Inflammation plays a central role in atherosclerosis, in which fatty deposits clog your arteries.
