Fibrinogen is a coagulation protein, mainly in the blood, also known as blood fibrinogen, which has a coagulation effect and is an important substance in the clotting process and in the formation of blood clots. If fibrinogen is elevated, it can lead to the occurrence of thrombotic diseases. If a person has a history of hypertension, it can induce further elevation of hypertension, combined with hyperlipidemia causing cerebral thrombosis, and angina pectoris. Elevated fibrinogen is also a major factor in the formation of atherosclerosis, leading to slowed blood flow, narrowing of the lumen, and increased blood viscosity. Fibrinogen is also involved in fat metabolism. Generally, obese people have a slower metabolism and higher fibrinogen in their blood, which puts them at risk for hypertension, cerebral thrombosis, and coronary heart disease. For people with pathogenic factors, intervention therapy is also needed to prevent thrombosis.
