Fibrinogen is a protein produced by the liver that plays a central role in blood clot formation. Beyond clotting, elevated fibrinogen is an independent risk factor for heart attack and stroke — it reflects both inflammation and a hypercoagulable state. It rises during acute illness, chronic inflammation, smoking, and obesity. Monitoring fibrinogen alongside hs-CRP provides a more complete picture of cardiovascular inflammation.
