Acute myocardial infarction(AMI) is still the leading factor causing crippling and death in cardiovascular disease.Percutaneous coronary intervention(PCI) can significantly reduce inpatient mortality and incidence of complication.But owing to the existence of restenosis,in-stent thrombosis,etc.,recurrent post-PCI cardiovascular events and high repeatability of hospitalization,as well as its crippling rate and mortality, remain a serious threat to the society and the patients’ family.Therefore,the appraisal and intervention in post-PCI associated risk factors has presently become one of the foci in clinical research.To improve the near-and long-term prognosis and quality of life in post-PCI AMI patients,further improvement of the evaluation system in risk factors and prognosis is necessary in order to provide a theoretical basis for early application of intervention in high-risk patients in clinical practice.This thesis mainly dissertates some explicit and valuable factors for clinical prognosis evaluation in recent studies,involving C-reactive protein(CRP),tumor necrosis factor-α(TNF-α),brain natriuretic peptide(BNP),atrial natriuretic peptide(ANP),Chinese medicine(TCM) syndrome, their correlation with clinical state and course of AMI,and their importance in clinical prognosis.
