Pharmacological Effects of Botanical Drugs on Myocardial Metabolism in Chronic Heart Failure.

Although there have been significant advances in the treatment of heart failure in recent years, chronic heart failure remains a leading cause of cardiovascular disease-related death. Many studies have found that targeted cardiac metabolic remodeling has good potential for the treatment of heart failure. However, most of the drugs that increase cardiac energy are still in the theoretical or testing stage. Some research has found that botanical drugs not only increase myocardial energy metabolism through multiple targets but also have the potential to restore the balance of myocardial substrate metabolism. In this review, we summarized the mechanisms by which botanical drugs (the active ingredients/formulas/Chinese patent medicines) improve substrate utilization and promote myocardial energy metabolism by activating AMP-activated protein kinase (AMPK), peroxisome proliferator-activated receptors (PPARs) and other related targets. At the same time, some potential protective effects of botanical drugs on myocardium, such as alleviating oxidative stress and dysbiosis signaling, caused by metabolic disorders, were briefly discussed.

Characterization of mild or asymptomatic patient admitted with Omicron variant of COVID-19 infection in Tibetan mobile cabin hospital China, August-October 2022.

Background: Prior to August 7, 2022, there had been no positive cases of novel coronavirus in Tibet for 920 consecutive days. However, with the first case of Omicron variant infection, the disease rapidly spread and was prevalent in Tibet for nearly 3 months, from August 7th to November 1st. With the spread of the epidemic, the local government responded quickly and established several mobile cabin hospitals to treat patients with mild and asymptomatic Omicron infection. However, the epidemiological and clinical characteristics of these patients are unknown. Methods: This is a retrospective study including a total of 14,264 mild and asymptomatic cases with Omicron infection in Tibet between August to October, 2022. The clinical data and epidemiological characteristics of COVID-19 cases admitted to Tibet mobile cabin hospitals were collected by using standardized forms from mobile cabin hospital database system, including demographic characteristics, onset symptoms, medication use, past medical history, hospitalization time, and discharge time. In terms of statistical analysis, multivariate Cox regression model was used to analyze the relationship between case characteristics and the length of stay in hospital. Results: Among 14,264 patients infected with Omicron, the average length of hospital stay was six (4-8, Interquartile range) days. Fifty percent of the patients were discharged by the 6th day, and 90% were discharged by the 10th day. Patients of all ages are generally susceptible to COVID-19, and there was no difference in discharge time, but the average length of hospital stay of Tibetan patients with COVID-19 was longer than that of Han patients. According to the statistics of clinical symptoms, sore throat (38.7%) and fever (19.4%) were the most common symptoms, while muscle pain (17.4%), cough (16.6%), and expectoration (13.2%) were also common. In addition, patients with chronic gastritis had significantly longer hospital stays. Conclusion: Based on the experience of Tibet mobile cabin hospitals and data analysis, we believe that patients of all ages are generally susceptible to Omicron. Compared with other novel coronavirus strains, Omicron infected patients had a shorter hospital stay, and treatment of symptoms is expected to shorten the time of nucleic acid negative conversion.

Danhong Injection Up-regulates miR-125b in Endothelial Exosomes and Attenuates Apoptosis in Post-Infarction Myocardium.

OBJECTIVE: To investigate the involvement of endothelial cells (ECs)-derived exosomes in the anti-apoptotic effect of Danhong Injection (DHI) and the mechanism of DHI-induced exosomal protection against postinfarction myocardial apoptosis. METHODS: A mouse permanent myocardial infarction (MI) model was established, followed by a 14-day daily treatment with DHI, DHI plus GW4869 (an exosomal inhibitor), or saline. Phosphate-buffered saline (PBS)-induced ECs-derived exosomes were isolated, analyzed by miRNA microarray and validated by droplet digital polymerase chain reaction (ddPCR). The exosomes induced by DHI (DHI-exo), PBS (PBS-exo), or DHI+GW4869 (GW-exo) were isolated and injected into the peri-infarct zone following MI. The protective effects of DHI and DHI-exo on MI hearts were measured by echocardiography, Masson's trichrome staining, and TUNEL apoptosis assay. The Western blotting and quantitative reverse transcription PCR (qRT-PCR) were used to evaluate the expression levels of miR-125b/p53-mediated pathway components, including miR-125b, p53, Bak, Bax, and caspase-3 activities. RESULTS: DHI significantly improved cardiac function and reduced infarct size in MI mice (P<0.01), which was abolished by the GW4869 intervention. DHI promoted the exosomal secretion in ECs (P<0.01). According to the results of exosomal miRNA microarray assay, 30 differentially expressed miRNAs in the DHI-exo were identified (28 up-regulated miRNAs and 2 down-regulated miRNAs). Among them, DHI significantly elevated miR-125b level in DHI-exo and DHI-treated ECs, a recognized apoptotic inhibitor impeding p53 signaling (P<0.05). Remarkably, treatment with DHI and DHI-exo attenuated apoptosis, elevated miR-125b expression level, inhibited capsase-3 activity, and down-regulated the expression levels of proapoptotic effectors (p53, Bak, and Bax) in post-MI hearts, whereas these effects were blocked by GW4869 (P<0.05 or P<0.01). CONCLUSION: DHI and DHI-induced exosomes inhibited apoptosis, promoted the miR-125b expression level, and regulated the p53 apoptotic pathway in post-infarction myocardium.

A randomized, placebo-controlled, double-blind trial to evaluate efficacy and safety of Shen-Yuan-Dan capsules, a traditional Chinese medicine, for treatment of peri-procedure myocardial injury following percutaneous coronary intervention.

BACKGROUND: Peri-procedural myocardial injury (PMI) is a common complication of percutaneous coronary intervention (PCI), which cannot be entirely avoided using available treatments. The findings of earlier research have shown that Shen-Yuan-Dan (SYD) capsules, a traditional Chinese medicine, can potentially alleviating PMI. This study aimed to confirm further this hypothesis in a rigorous, well-designed randomized controlled study. METHODS: Our clinical trial was randomized, double-blinded, and placebo-controlled. A total of 181 patients with unstable angina (UA) undergoing elective PCI were randomized to pretreatment with SYD or a placebo under the basis of conventional treatment; 87 patients were pretreated with SYD (4 capsules, 3 times a day, with a further 4 capsules 2 h before PCI) 3 days before the procedure, and 94 patients were given a placebo. No patients received reloading statins before PCI, and SYD or placebo was maintained for 1 month after PCI. The primary endpoint was the incidence of PMI. The secondary endpoint was calculating the incidence rate of all 30-day major adverse cardiovascular events (all-cause mortality, non-fatal myocardial infarction, unplanned revascularization). The safety outcomes, including abnormalities in electrocardiogram and serum biochemical examinations caused by drug use, were also tested. RESULTS: The levels of creatine kinase-myocardial band (CK-MB) in both the SYD and placebo groups were increased at 4 h and 24 h after PCI compared with before the procedure (P < 0.05). The incidence rate of PMI in the SYD group (10.3 %) was lower than that in the placebo group (34 %) (absolute difference, 23.7 % [95 % CI, 11.7-34.8 %], P < 0.01). After taking SYD, the relative risk reduction (RRR) and absolute risk reduction (ARR) were 69.7 % and 24.3 %, respectively; further, number needed to treat (NNT) was 4.2. The 30-day major adverse cardiovascular event (MACE) rate was not statistically different between the SYD and placebo groups (6.9 % vs. 9.6 %, P = 0.352). There were no abnormal situations during the trial. CONCLUSION: These findings showed that pretreatment with SYD could safely reduce the incidence rate of PMI in patients with UA undergoing elective PCI. Further study on the effects of SYD and how it can improve adverse cardiovascular events outcomes is needed.

Traditional Chinese medicine injections with activating blood circulation, equivalent effect of anticoagulation or antiplatelet, for acute myocardial infarction: A protocol for the systematic review and meta-analysis of randomized clinical trials.

BACKGROUND: In spite of a growing number in the use of percutaneous coronary intervention (PCI) in China, the mortality of acute myocardial infarction (AMI) has not decreased. Traditional Chinese medicine injections for Activating Blood Circulation (TCMi-ABC), equivalent effect of anticoagulation or antiplatelet, are widely used in China; however, the improvement of fatality towards AMI is unclear. Therefore, we intend to conduct a systematic review and meta-analysis to evaluate the efficacy and safety of TCMi-ABC in treatment with AMI. METHODS: Based on the "National Medical Products Administration of China," TCMi-ABC with AMI treatment indication will be selected, including Danhong injection, Sodium Tanshinone IIA Sulfonate injection, Danshen Chuanxiongqin injection, and Puerarin injection. Randomized controlled studies will be searched from as follows: PubMed, Embase, the CENTRAL in Cochrane Library, Chinese Biomedical Literature Database (SinoMed), China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), and Wanfang Data Knowledge Service Platform. Two researchers will work independently on literature selection, data extraction, and quality assessment. The outcomes focus on the effects of TCMi-ABC on fatality of patients with AMI in hospitalization and in the long term, the incidence of malignant arrhythmia, left ventricular ejection fraction, and adverse events. RevMan 5.4.1 software was used for mate analysis. RESULTS: This study will conduct a comprehensive literature search and provide a systematic synthesis of current published data to explore the efficacy and safety of TCMi-ABC for AMI. CONCLUSION: This study will provide high-quality evidence for treatment of AMI with TCMi-ABC in terms of efficacy and safety, which may help clinicians make a better complementary treatment schedule of patients with AMI.

Clinical Characteristics and Risk Factors of Periprocedural Myocardial Injury in Patients with Elective PCI in a TCM Hospital.

Objective: To investigate the clinical characteristics of patients with unstable angina (UA) who received elective percutaneous coronary intervention (PCI) in a traditional Chinese medicine (TCM) hospital and to analyze the related risk factors of periprocedural myocardial injury (PMI). Methods: On the basis of cross-sectional investigation, the case-control method was adopted. We retrospectively collected clinical data of patients with UA who successfully received elective PCI in Beijing Hospital of TCM from February 2017 to February 2019. Based on the occurrence of PMI, the case-control was formed. The influence of related factors on PMI occurrence was analyzed using the logistic multiple regression equation based on the parameters between the comparison groups. Results: 1. Incidence of PMI and related clinical features: Of the 265 UA patients, the incidence of PMI was 26.4%, nearly one quarter (23.4%) had old myocardial infarction, nearly half (45.3%) had previously received coronary intervention. The prevalence of patients with previous hypertension (75.8%), type 2 diabetes (57%), and high-low-density lipoprotein cholesterolemia (69.3%) exceeded 50%, more than 50% of the patients have triple-vessel disease (50.2%). 2. Features of TCM syndrome elements: The main TCM syndromes of the investigated patients are blood stasis syndrome (81.1%) and Qi deficiency syndrome (77.3%), the others include Phlegm turbidity syndrome (53.2%), Yang deficiency syndrome (50.9%), Yin deficiency syndrome (50.1%), Qi stagnation syndrome (30.1%), and coagulated cold syndrome (17.1%). 3. Factors of PMI occurrence: According to the occurrence of PMI, 265 patients were divided into PMI group (n = 70) and non-PMI group (n = 195). The comparison between groups shows that the preoperative SYNTAX score, the number of stents, and the total length of stents of the patients in the PMI group were higher than those in the non-PMI group (P < 0.05); the patients in the PMI group treated by Shen-Yuan-Dan (SYD), a Chinese medicine prescription with Qi-supplementing and blood stasis-purging, were significantly lower than those in the non-PMI group (P < 0.05). Brought these four factors (preoperative SYNTAX score, number of stents implanted, total length of implanted stents, and treated by SYD) into the binary logistic regression equation, those who were only treated by SYD have statistical significance in the equation as a protective factor (OR 0.327, 95% CI 0.117-0.916, P=0.033). Conclusion: Patients with UA who received elective PCI in TCM institutions may have clinical characteristics including multiple accompanying diseases and high stenosis coronary artery, in which the incidence of poor blood glucose control and high rate of three-vessel coronary disease are particularly significant. The TCM syndromes are mainly Qi deficiency and blood stasis syndromes. The decrease of PMI may be attributed to the application of SYD in the real world. This trial is registered at ChiCTR2100043465.

Acute Myocardial Infarction in Chinese Medicine Hospitals in China from 2006 to 2013: An Analysis of 2311 Patients from Hospital Data.

OBJECTIVE: To assess the trends in characteristics, treatments, and outcomes of acute myocardial infarction (AMI) patients in tertiary Chinese medicine (CM) hospitals in China between 2006 and 2013. METHODS: This retrospective study was based on two nationwide epidemiological surveys of AMI in tertiary CM hospitals during 2 years (2006 and 2013). Patients admitted to the hospital for AMI were enrolled. Hospital records were used as the data source. Case data were derived regarding baseline characteristics, treatments, and outcomes of patients to assess changes from 2006 to 2013. Logistic regression was used to analyze the relationship between prognosis, general influencing factors of disease, and various treatment measures. RESULTS: Totally 26 tertiary CM hospitals in 2006 and 29 tertiary CM hospitals in 2013 (18 were repetitive) were surveyed. A total of 2,311 patients with AMI were enrolled (1,094 cases in 2006 and 1,217 cases in 2013). From 2006 to 2013, the mean age did not significantly change, but the proportion of patients younger than 65 years increased. The prevalence of risk factors such as hypertension, diabetes, and hyperlipidemia also increased. Significant increases were observed in primary percutaneous coronary intervention [20.48% (2006) vs. 24.90% (2013)] and revascularization [36.11% (2006) vs. 52.42% (2013)]. In-hospital mortality decreased from 11.15% in 2006 to 10.60% in 2013. A mortality logistic regression analysis identified reperfusion therapy [odds ratio (OR), 0.222; 95% confidence interval (CI), 0.106-0.464], Chinese patent medicines (OR, 0.394; 95% CI, 0.213-0.727), and CM decoctions (OR, 0.196; 95% CI, 0.109-0.353) as protective factors. CONCLUSION: Reperfusion and revascularization capabilities of tertiary CM hospitals have improved significantly, but in-hospital mortality has not significantly decreased. Efforts are needed to improve medical awareness of AMI and expand the use of CM to reduce in-hospital mortality in China.

Danhong injection enhances angiogenesis after myocardial infarction by activating MiR-126/ERK/VEGF pathway.

BACKGROUND/AIM: Danhong injection (DHI) is a Chinese drug used for relieving cardiovascular diseases. This study aimed to identify the effect and mechanism of action of DHI on post-infarct angiogenesis, especially the epigenetic regulation of angiogenesis. METHODS: A myocardial infarction (MI) mouse model was induced by ligating the left anterior descending coronary artery. A 4-week daily treatment with or without DHI via intraperitoneal injection was started immediately following MI. The changes in cardiac function, pathology, and angiogenesis following MI were measured by echocardiography and immunostaining. Matrigel tube formation and scratch wound assays were used to evaluate the effect of DHI on the proliferation and migration of hypoxic human umbilical vein endothelial cells (HUVECs). The expression of miR-126, Spred-1, and angiogenesis-related mRNAs was measured by quantitative real-time polymerase chain reaction (qRT-PCR). The expression of related proteins and the phosphorylated levels of extracellular signal-regulated kinase (ERK) and protein kinase B were detected by Western blot analysis. The loss-of-function study was performed using antagomir-126. RESULTS: The DHI-treated mice had significantly reduced infarct area, improved ejection fraction, and increased capillary density 4 weeks after MI. Also, DHI promoted the proliferation and migration of hypoxic HUVECs. The qRT-PCR and Western blot analysis revealed that DHI intervention upregulated miR-126, suppressed Spred-1 expression, and activated the ERK pathway, but not the Akt pathway. The loss-of-function study showed the blockade of the pro-angiogenic effect of DHI by antagomir-126 involving the ERK/vascular endothelial growth factor (VEGF) pathway. CONCLUSION: DHI enhanced post-infarct angiogenesis after MI by activating the miR-126/ERK/VEGF pathway.

Efficacy and safety of Shen-Yuan-Dan capsules for peri-procedural myocardial injury following percutaneous coronary intervention: study protocol for a randomized, double-blind, placebo-controlled trial.

BACKGROUND: Peri-procedural myocardial injury (PMI) during percutaneous coronary intervention (PCI) will result in an unfavorable clinical prognosis in patients, thus urgently necessitating effective drug treatment measures. Shen-Yuan-Dan (SYD) capsules are a traditional Chinese medicine (TCM) preparation that have been found to have potential myocardial protection effects during the peri-procedural phase of PCI in previous clinical and basic research; however, there is a lack of rigorous, randomized, and controlled studies. The aim of this study is to evaluate the efficacy and safety of SYD in decreasing PMI. METHODS: This is a randomized, double-blind, placebo-controlled clinical trial. A total of 284 patients with unstable angina will be randomized into test and control groups. The two groups will be given SYD or a placebo (three times each day, four capsules each time) 3 days before PCI on the basis of conventional treatment. Twelve hours before PCI, an additional 4 capsules will be given, and drug treatment is planned to be maintained for 1 month after surgery. Dynamic changes in the myocardial enzyme in four time-points (before PCI, and 4, 24, 48 hours after PCI) in both groups of patients that will be observed. The follow-up period will be 1 month. The primary observation markers are planned to evaluate the efficacy and safety of SYD in decreasing PMI. The secondary observation markers will be to evaluate the major adverse cardiovascular events (MACEs) status at day 30 after PCI, (all-cause mortality, non-fatal myocardial infarction, repeated revascularization of target blood vessel) and Seattle Angina Questionnaire scores. GRACE scores will be used for risk stratification, and the intervention efficacy of SYD on PMI patients with different risks will be retrospectively evaluated. DISCUSSION: This study will provide a rigorous clinical evidence to evaluate the efficacy and safety of SYD in decreasing PMI and the results are worth anticipating. TRIAL REGISTRATION: The design of this trial has been registered with the Chinese Clinical Trial Registry (No. ChiCTR-IPR-17011069).

A Study of Prognosis, Outcome, and Changing Tendency of Hospitalized AMI Patients in Beijing Third-Grade A-Level Traditional Chinese Medicine Hospitals from 1999 to 2008.

Objectives. To survey and analyse the prognosis, outcome, and changing tendency of the Acute Myocardial Infarction (AMI) patients in Beijing third-grade A-level Traditional Chinese Medicine (TCM) hospitals. Methods. We collected the clinical datum of hospitalized AMI patients in Beijing 6 TCM hospitals from January 1999 to December 2008 and then analysed the clinical datum. Results. (1) The mean age of patients had showed a slowly rising tendency during this ten years. The patients who had previous history of cerebrovascular diseasea and multiple comorbidities had increased year by year. (2) The rate of reperfusion therapy, revascularization and standardized using of drug, and usage of TCM of AMI patients presented a significant increasing tendency in these hospitals. (3) The proportion of AMI patients combined with cardiac arrhythmia and heart failure had decreased significantly. (4) The AMI mortality presented a decreasing tendency in 10 years. Conclusions. The AMI patients in Beijing TCM hospitals had their own unique clinical features, and it can improve their prognosis by combined therapy of Western Medicine and Traditional Chinese Medicine.

Characteristics and advantages of traditional Chinese medicine in the treatment of acute myocardial infarction.

OBJECTIVE: To obtain epidemiological data on Traditional Chinese Medicine (TCM) therapeutic status of acute myocardial infarction (AMI) and to determine TCM characteristics and advantages to improve the level of TCM prevention and treatment of AMI. METHODS: Clinical epidemiology methods were used to register and survey the TCM therapeutic status of hospitalized AMI patients. In 2001, the Chinese Association of Integrative Medicine surveyed the therapeutic status of 3308 AMI patients hospitalized in 30 hospitals in Beijing and Shanghai from 2000-2001. The Beijing Collaborative Study Group on Therapeutic Status of Acute Myocardial Infarction (the Study Group) then conducted a 10-year-long register survey on hospitalized AMI patients in Third-grade A-Level TCM hospitals in Beijing. After 2002, the Study Group further surveyed the treatment conditions of AMI-hospitalized patients in 10 Second-grade A-Level TCM hospitals. The therapeutic status in 8 Third-grade A-Level Western medicine hospitals was surveyed in 2001 and 2005 as a control. In 2008, in cooperation with the China Association of Chinese Medicine, the Study Group further performed a survey at 26 Third-grade A-Level TCM hospitals nation-wide. Approximately 5000 cases were investigated to obtain authoritative data on the therapeutic status of AMI patients in TCM hospitals in China. RESULTS: We found that Chinese herbal intravenous preparations may be beneficial in reducing the mortality of AMI. Major complications of AMI, such as heart failure and arrhythmia, were significantly less during the 10-year survey period. The mortality of hospitalized AMI patients showed a decline. TCM treatment was helpful for AMI patients in improving their quality of life. Ten-year dynamic monitoring showed that the ability to perform reperfusion and to use drugs appropriately, as well as an effort to carry out the Clinical Guidelines has made great progress in TCM hospitals. However, TCM hospitals still have some problems in treating AMI, including a lack of standardized TCM syndrome diagnosis, the need for syndrome differentiation and treatment standardization, and clinical skills in reperfusion and standardized drug treatment still need to be further improved. Compared with AMI patients in Western medicine hospitals during the same period, those in TCM hospitals had the following characteristics: they were admitted to hospital later; they were older when they had a heart attack; there were more females, they had more problems in their medical history, and they had more concomitant illnesses and complications. Therefore, the demographic baseline data were significantly different between AMI patients in TCM hospitals and those in Western medicine hospitals. This indicated that patients in TCM hospitals were more critical than those in Western medicine hospitals. CONCLUSIONS: TCM has special advantages in treating AMI. TCM hospitals are making continuous progress in standardized treatment of AMI, but further improvement is still required. AMI patients in TCM hospitals have some special characteristics, and their condition may be more critical. Further clinical research on TCM treatment of AMI is required.

[Survey on the hospitalization treatment status of acute myocardial infarction patients in 13 hospitals of western medicine and traditional Chinese medicine in Beijing].

OBJECTIVE: To survey the treatment status and clinical features of hospitalized patients with acute myocardial infarction (AMI) of 13 hospitals in Beijing in 2005. METHODS: Uniform questionnaires were used to register AMI patients hospitalized from January 1 to December 31, 2005 in the 13 hospitals including traditional Chinese medicine (TCM) hospitals (n = 6) and western medicine hospitals (WM, n = 7) from Beijing. A total of 1663 AMI patients were registered (1366 cases in WM hospitals and 297 cases in TCM hospitals). An Access database was established and patient information was input, the clinical features and treatment status of hospitalized AMI patients were analyzed. RESULTS: The mean age was (63.9 +/- 12.8) years old [(62.8 +/- 12.8) years for WM Hospitals and (69.1 +/- 11.8) years for TCM hospitals, P < 0.05], male to female ratio was 2.4:1 (2.7:1 for WM hospitals and 1.6:1 for TCM hospitals, P < 0.05). The median time to hospital was 14 hours in TCM hospitals and 11 hours in WM hospitals (P > 0.05). Incidences of history of cerebrovascular disease, high blood pressure, diabetes, hyperlipidemia and complications such as in-patient arrhythmia, cardiac insufficiency, cardiogenic shock were significantly higher in TCM hospitals than in WM hospitals. The total mortality of 1663 AMI cases was 8.2% (15.8% in TCM hospitals vs. 6.6% in WM hospitals, P < 0.01). The reperfusion rate including emergency PCI and thrombolytic therapy rate was 31.3% in 13 hospitals (33.3% in WM hospitals vs. 21.9% in TCM hospitals, P < 0.05). Percent of guideline recommend drug use for AMI was as follows: aspirin 93.6%, ACEI and ARB 85.1%, beta-blocker 78.7%, low molecular weight heparin 85.4%, statins 74.7%. CONCLUSIONS: Reperfusion therapy and guideline recommended drugs were widely used although there was a need for further improvement. The hospitalized mortality showed a downward trend compared with results from five years ago, patients in TCM hospitals had an independent clinical features.

[Study on the therapeutic status of 1242 hospitalized acute myocardial infarction patients in Beijing].

OBJECTIVE: To investigate and analyze the therapeutic level and the existing problems on acute myocardial infarction (AMI) management in Beijing. METHODS: We collected clinic data of 1242 AMI patients from 12 hospitals in Beijing, from January 2000 to March 2001, using a uniformed questionnaire, and evaluated the status of the diagnosis and treatment of AMI according to the Chinese guidelines issued on Decmeber 2001. Corresponding factors which influencing the mortality were also analyzed by one-way factor and multiple factors analysis methodologies. RESULTS: The mean age of the 1242 AMI patients was 63.0 years old and about one third of them were under 55 years old. In hospitals, the total mortality was 9.10%. 37.9% of the patients had received therapy of the intravenous thrombolysis and emergency PCI with a total rate of reperfusion therapy as 56.0%. The in-hospital rates of drug use were as follows: Nitrates 90.0%, Aspirin 87.8%, heparin 88.7%, beta-blockers 73.4%, angiotensin converting enzyme inhibitors(ACEI) 77.6%, lipid regulating agents 43.6%. The rate of intravenous therapy of TCM by promoting the blood circulation and supplementing the vital energy was 30.5%. Results from multiple factors analysis showed that the compositive factors which could lower the mortality were reperfusion therapy,lipid regulating agents, intravenous therapy of TCM, beta-blockers, ACEI, lower molecule heparin and digitalis. CONCLUSION: Data from this study showed that there still existed a gap between clinical management on AMI and the guideline in Beijing. To set up a straightway passage of reperfusion therapy, to become more standardized to follow the guideline in undertaking the medical treatment practice, and to go deep into discuss the status of TCM on AMI management seemed the important tasks we are facing.
