CRP and coronary artery disorder: Inflammatory response is an important factor affecting plaque progression.[35] CRP is a kind of protein secreted in the blood during acute inflammation and reflects the inflammatory status of the organism.[29] The concentration of CRP in serum is positively correlated with the formation of atherosclerosis and the severity of CAD.[30,31] Therefore, CRP can be used as an important index to measure the risk of CAD after PCI.[37] The results showed that the combination of YQHX with CWM was better than CWM alone in reducing CRP.
