Although not specific, serum C-reactive protein is involved in atherosclerosis and is a risk factor for cardiovascular disease, although it is not specific for various inflammatory conditions and acute injuries. The higher the C-reactive protein value, the more severe the atherosclerosis. elevated C-reactive protein is commonly found in the following diseases: acute and chronic infections, tissue trauma, rheumatic diseases, hepatitis, cardiovascular diseases, etc. Since it is not specific, it needs to be combined with clinical manifestations and other ancillary tests to determine which disease it belongs to. . Atherosclerosis can lead to narrowing of the lumen of blood vessels and symptoms of myocardial ischemia such as chest tightness and shortness of breath and pain in the precordial region, so elevated C-reactive protein alone cannot determine whether it is inflammation or tissue damage.
