Professor Zhang Mingxue's Experience In Treating Angina Pectoris After PCI With The Method Of "invigorating Qi And Activating Blood, Resolving Phlegm And Dredging Collaterals"

Percutaneous coronary intervention(PCI),including percutaneous transluminal coronary angioplasty(PTCA)and coronary stent placement,is one of the main surgical treatments for coronary heart disease.In recent years,the mortality and disability rates in patients with coronary heart disease significantly reduced with the development and popular of PCI technology,but the incidence rate of restenosis(RS)after PTCA 3-6 months can be as high as50%,and although the RS incidence of intracoronary stent placement is low,but still around15-20%[1].Restenosis,caused by thrombosis after PCI or vascular hyperplasia and reconstruction,etc,can lead intravascular blood flow obstruction,cardiac blood supply dropped sharply,resulting in myocardial ischemia,hypoxia and myocardial cell injury,and cause angina symptoms such as chest pain and sense of suppression in the chest,seriously affect the quality of life of patients,and hinder the long-term efficacy of interventional therapy,so that the intervention measures for recurrent angina after PCI has gradually become the focus in the field of cardiovascular research.Because the long-term effect of PCI is uncertain,the patients with restenosis after PCI may not be able to receive secondary surgery.In the case of taking oral drug therapy as the main tratment,traditional Chinese medicine(TCM)combine the differentiation of disease and treatment according to syndrome differentiation to treat recurrent angina pectoris after PCI for coronary heart disease with its unique advantages.Professor Zhang Mingxue has accumulated a lot of clinical experience in the treatment of patients with recurrent angina pectoris after PCI.Through a systematic summary of the experience of many physicians in diagnosis and treatment,and combine the research results of ancient and modern literature and modern medicine with clinical practice,suggesting that the core pathogenesis of recurrent angina after operation is weakness of heart qi,phlegm and blood stasis blocking collaterals,in which qi deficiency as the basis,phlegm and blood stasis as the superficial syndrome.According to the pathogenesis characteristics of the disease,my tutor treated the disease with the method of invigorating qi and activating blood circulation,eliminating phlegm and dredging collaterals,modified Shenqi Gualou Banxia xiebai decoction,Shengxian decoction and Xuefu Zhuyu decoction to form the basic prescription mainly composed of radix panacis quinquefolii(ginseng),radixastragali,Banxia,Trichosanthes,xiebai,shengma,Bupleuri radix,platycodon grandiflorum,radix paeoniae rubra,poria,raw licorice,raw keel and other medicines,and add and subtract with the syndrome,the therapeutic effects are satisfactory.This paper summarizes the clinical experience of the tutor in the diagnosis and treatment of this disease,hoping to provide effective methods and ideas for clinical prevention and treatment of angina pectoris after PCI.
