RESUMO
The prevalence and mortality of cardiovascular diseases are still on the rise in China. Percutaneous coronary intervention(PCI)is the most effective strategy to reduce coronary artery stenosis and occlusion, it can also improve clinical symptoms on patients with coronary heart disease. Clinically, a large number of patients still have heartache symptoms after recanalization of the great vessel. During the perioperative period, PCI is often accompanied with adverse events such as oxidative stress, inflammation, calcium overload, endothelial function damage, and thrombus obstruction. More specifically, during the process of PCI, oxidative stress is more severe than other damages. For example, during the reperfusion period of PCI, the outbreak of reactive oxygen species (ROS) can lead to abnormal mitochondrial energy transfer and cell ion homeostasis, resulting in endothelial cell injury, it can also increase the level of vascular permeability, albumin leakage, the adhesion of leukocyte and platelet, and the level of vascular stenosis. After PCI, traditional Chinese medicine(TCM) brings vasucular restenosis into the category of " palpitation" . The movement of Qi and bloods is tightly related to the five Zang-orans. When the movement of Qi and blood is stagnant, the function of the heart's blood production and circulation is blocked, resulting in Qi of deficiency and blood stasis, thus causing a state of physical weakness. Moreover, at present, Probucol and Ticagrelor and other first-line clinical drugs have certain limitations, and ignore the body' s current status of " essential illusory and real" , unable to coordinate the relationship between the body' s Qi and blood, Yin, Yang and five zang-organs. The purpose of this research is to perform the negative effects of oxidative stress on coronary artery based on the molecular research of modern medicine accompanied with acknowledgement of TCM and to conclude the process of researching prevention and treatment of TCM, and to provide reference for the treatment of coronary artery and coronary artery experimental study.
