In the past decade, the rapid development of coronary intervention and coronary artery bypass technology has brought the treatment and prognosis of coronary artery disease into a new situation, but it cannot solve all the problems, there are still many patients with angina pectoris and decreased cardiac function after surgery, and most of these patients have complex lesions on review coronary angiography, or basic patency of blood vessels but show diffuse lesions, or left ventriculography shows reduced myocardial motility, enlarged heart chambers, etc. Cardiomyopathy manifestations. Over the past 2 years, we have used Chinese medicine Ginseng Jianxin Tang (capsule) to treat 60 patients after coronary flow reconstruction, and achieved better results, as reported below: 1, Clinical data 1.1 General data: 60 cases were from the outpatient clinic and ward of the Affiliated Hospital of Shandong University of Traditional Chinese Medicine. There were 42 male cases and 18 female cases, aged 52-70 years, with a duration of coronary heart disease of 3-25 years. There were 36 cases after stenting, including 5 cases after emergency coronary stenting, 19 cases after bypass surgery, and 5 cases after stenting combined with bypass surgery. There were 42 cases performed in provincial hospitals and above, and 18 cases performed in municipal hospitals. There were 10 cases of myocardial infarction. 1.2 Past history: Among the 60 patients, 30 had a history of hypertension with a disease duration of 5-16 years, 35 had a history of hyperlipidemia with a disease duration of 6-12 years, and 36 had a history of diabetes mellitus with a disease duration of 3-12 years. All of them are currently in the normal range by medication control. 1.3 Preoperative imaging data: Among the 60 patients, 48 patients could provide detailed coronary angiographic data, including 10 cases with three lesions, 18 cases with two lesions, 15 cases with complete occlusion of a single vessel, 26 cases with diffuse lesions suggested by the imaging report, and 8 cases with collateral circulation. 1.4 Postoperative angiographic data: Among the 60 patients, 8 cases had postoperative coronary angiograms reviewed, and none of them had in-stent or bridge stenosis, 2 cases showed single-branch complete occlusion with collateral circulation formation, 2 cases showed chamber enlargement or ventricular hypokinesis, and 4 cases showed diffuse lesions. 1.5 Symptom information: 8 cases of spontaneous angina and 19 cases of exertional angina in 60 patients, including 7 cases of Canadian class I, 8 cases of class II and 4 cases of class III; 8 cases of class I, 35 cases of class II, 15 cases of class III and 2 cases of class IV of cardiac function classification (New York classification). 1.6 TCM symptom data: Among 60 patients, there were 55 cases of weakness, 40 cases of chest tightness, 27 cases of chest pain, 40 cases of panic, 30 cases of dizziness, 30 cases of spontaneous sweating, 40 cases of dry mouth, 38 cases of heartburn, 27 cases of poor appetite or abdominal distension, 23 cases of cold fear and cold limbs, 27 cases of swelling of lower limbs, 45 cases of purple lips, 40 cases of dark or light purple tongue, 20 cases of slippery moss, 10 cases of yellow or thin yellow moss. 2, treatment methods 2.1 Western medicine treatment: postoperative conventional treatment: clopidogrel 75mg Qd, aspirin 100mg Qd; anti-angina treatment: Lunanxinkang, betalactam, hexinshang; antihypertensive, lipid regulating, hypoglycemic drugs are used according to the previous dose; digoxin, dihydroketorolac, if necessary. 2.2 Chinese herbal treatment: Ginseng and Heart Health Tang formula: Ginseng 10g, Astragalus 30g, Gui Zhi 9g, Atractylodes 15g, Ze Di 15g, Danshen 30g, etc. If angina pectoris is obvious, add Angelica sinensis, Chuanxiong, Yuanhu and Fangfeng; if dry mouth, add Medlar and Wuweizi; if swelling of lower limbs, add Yimoucao and Scapularia; if cold extremities, add Radix et Rhizoma and Cinnamomum; if pale tongue and lips are blue, add Angelica sinensis and Chuanxiong; if disturbed heart, add Yunling, etc. The above formula is taken with water decoction, 1 dose daily, divided into 2 warm doses, depending on the condition for 1-2 months. Ginseng Heart Capsules (made by the preparation room of the hospital according to the composition of the soup) are taken 6 capsules each time, 3 times a day for 3 months. 3. Observation methods and indexes: A total of 3 months of treatment, monthly record of angina attacks, changes in cardiac function, use of nitrates, digoxin, diuretic drugs, changes in TCM symptoms, etc. 4, statistical methods: before and after treatment to do control, cardiac function improvement using the chi-square test. 5.Treatment results 5.1 Changes in angina and cardiac function before and after treatment (see Table 1) Table 1 Changes in angina and cardiac function grading before and after treatment Exertional angina Cardiac function grading Spontaneous angina Ⅰ Ⅱ Ⅲ Ⅰ Ⅱ Ⅲ Ⅳ Before treatment 8 7 8 4 8 35 12 2 After treatment 3 6 3 0 38 18 4 0 As seen in Table 1, angina attacks were significantly reduced after treatment. The cardiac function was significantly better, and the changes before and after cardiac function grading were very significantly different by chi-square test (P<0.01). 5.2 Changes in TCM symptoms before and after treatment (see Table 2) Table 2 Changes in TCM symptoms before and after treatment Lack of energy Chest tightness Chest pain Heartburn Dizziness Na poor mouth Dryness Spontaneous sweating Heart irritation Cold fearing mouth and lips Pale purple tongue Watery smooth moss Yellow moss Abdominal distension Cold limbs Purple or dark Before treatment 55 40 27 40 30 27 40 30 38 23 45 40 20 10 After treatment 20 15 12 10 9 2 10 15 12 6 20 20 5 2 As seen from Table 2 , there was a significant improvement in TCM symptoms after treatment. 5.3 Western medicine taking before and after treatment: after treatment, all drugs such as digoxin and dihydroketuria were stopped, and anti-anginal drugs were reduced. 6, analysis The data of this group has a long duration of coronary heart disease, mostly combined with a history of hypertension, hyperlipidemia and diabetes mellitus, so that the coronary lesions are complex and extensive, especially diabetes mellitus is likely to cause diffuse vascular damage and myocardial function damage. Some patients cannot provide complete imaging pictures or CD-ROMs, and only the imaging report shows heavy coronary lesions, such as diffuse lesions, completely occluded lesions combined with collateral circulation formation, three-branch lesions, etc. With the improvement of interventional technology and the improvement of stents and other devices, especially the role of drug stents, the restenosis rate has been greatly reduced, and the postoperative angiograms show no stenosis in the stent, but show that the wall is not smooth, or diffuse lesions, or myocardial function damage. Since stenting and bypass only play a "repairing" role on local large vessels, but the extensive coronary lesions cannot be changed, therefore, although there is no complete imaging data before treatment in this group, it can be tentatively inferred that the angina and the decline of cardiac function in these patients are caused by coronary small vessel, microvascular and myocardial lesions. In our data analysis, most of them have symptoms such as weakness, spontaneous sweating, chest tightness, chest pain, dry mouth, dizziness, coldness, cold limbs, and pale purple tongue, etc. Chinese medicine can identify the symptoms as qi deficiency, yang deficiency, blood stasis, and water stoppage. Due to the complexity of coronary artery lesions, the three vessels of coronary arteries supply different ventricular walls, which have different degrees of impact on cardiac function, and coronary artery lesions cannot be expressed quantitatively, and the samples are small, so regression analysis cannot be done, but from our experience, coronary artery lesions are mostly Qi deficiency and blood stasis in mild cases, and Yang deficiency and water stagnation in complex and heavy cases. Ginseng Jianxin Tang is a formula we have used for many years to treat chest paralysis and heart pain in coronary artery disease, and now it has been used in our hospital as our own preparation (capsule). In the formula, ginseng and astragalus benefit qi and restore vital energy, gui zhi promotes yang, ze xie facilitates water, and dan shen invigorates blood, and then add and subtract according to the different severity of yang deficiency, blood stasis and water stoppage, which has achieved better efficacy in treating coronary artery disease after coronary revascularization. The treatment results also showed that angina pectoris and cardiac function were significantly improved compared with those before treatment, and the TCM symptoms of Qi deficiency, Blood stasis, Yang deficiency and water stagnation, such as weakness, spontaneous sweating and chest tightness, were significantly improved. Although a reasonable control group could not be set up because the coronary lesions could not be expressed quantitatively, the patient's pre-treatment medication was already conventional and basically adequate, so by their own control, the therapeutic effect of Ginseng Jianxin Tang (capsule) could still be illustrated from the analysis of clinical symptoms efficacy. With the rapid development of modern medicine, especially the development of coronary interventional technology and the improvement of bypass surgery level in the past 10 years, the position of Chinese medicine in the treatment of coronary heart disease has shrunk somewhat. As for coronary microcirculation injury (including microvascular, small vessel and myocardial injury), which cannot be implemented and solved by intervention and bypass, Chinese medicine treatment has accumulated more experience, so carrying out Chinese medicine to prevent and treat coronary microcirculation injury will be an important research direction.
