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.     

Influence of ambulance use on early reperfusion therapies for acute myocardial infarction

Background Ambulance use expedites the definitive treatment of acute myocardial infarction （AMI）. The aim of this study was to evaluate the effect of ambulance use on the administration of early reperfusion therapies for patients with AMI in Beijing, China. Methods Data were prospectively collected from 498 patients with ST-elevation myocardial infarction （STEMI） who were admitted within 12 hours of symptom onset to 19 hospitals in Beijing between November 1,2005 and December 31, 2006. The baseline characteristics of and the initial management of the ambulance users and the non-ambulance users were compared. Results Only 186 （37.3%） patients used an ambulance as transportation to the hospital. Ambulance users were, on average, older and at relatively higher risk on presentation than the non-ambulance users. After adjustment for patient and hospital characteristics, ambulance use was associated with a greater early reperfusion rate, mainly because of a greater incidence of primary percutaneous coronary intervention. In addition, ambulance users had a significantly shorter median door-to-balloon （120 compared with 145 minutes, P 〈0.001） and symptom onset-to-balloon （223 compared with 300 minutes, P 〈0.001） time than non-ambulance users. Conclusions Ambulances are underused by AMI patients in Beijing. Ambulance use may lead to more frequent and faster receipt of early reperfusion therapies. New public health strategies should be developed to facilitate an increased use of ambulances by AMI patients.     

Elevated Platelet Activating Factor Level in Ischemia-Related Arrhythmia and Its Electrophysiological Effect on Myocardium

Objective The mechanism through which platelet activating factor (PAF) induces cardiac electrical activity and arrhythmia is not well understood and previous studies have suggested a potential involvement of ion channels in its action. The present study was aimed to clarify the role of PAF in fatal arrhythmias following acute myocardia infarction (AMI) and the underlying mechanism. Methods (1) Blood PAF levels were measured among 72 AMI patients at the time of diagnosis with AMI and 48 h later, and their electrocardiogram (ECG) was recorded continuously. (2) Ischemia simulation and surface electrocardiogram were conducted in 20 pigs and their PAF levels were measured. (3) PAF perfusion and standard microelectrode recording were performed on guinea pig papillarymuscles. Results In both humans and pigs, elevated PAF levels were detected in AMI and simulated ischemia, respectively, and even higher PAF levels were found when fatal arrhythmias occurred. In guinea pig myocardium, PAF induced a shortening of action potential duration at 90% level of repolarization (APD 90 )under non-ischemic conditions and a more pronounced shortening under early simulated ischemic conditions. Conclusion AMI and ischemia are associated with increased PAF levels in humans and pigs, which are further raised when fatal arrhythmia follows. The effects of PAF on the myocardium may be mediated by multiple ion channels.     

Predicting value of serum soluble ST2 and interleukin-33 for risk stratification and prognosis in patients with acute myocardial infarction

Background Acute myocardial infarction （AMI） is a common cardiac emergency with high mortality.Serum soluble ST2 （sST2） is a new emerging biomarker of cardiac diseases.The present study is to investigate the predictive value of sST2 and interleukin-33 （IL-33） for risk stratification and prognosis in patients with AMI.Methods Fifty-nine patients with AMI,whose chief complaint was chest pain or dyspnea,were selected for our study.Physical examination,chest radiograph,electrocardiograph （ECG）,biomarkers of myocardial infarction,NT-proBNP,echocardiography and other relevant examinations were performed to confirm the diagnosis of AMI.Thirty-six healthy people were chosen as the control group.Serum samples from these subjects （patients within 24 hours after acute attack） were collected and the levels of sST2 and IL-33 were assayed by enzyme-linked immuno-sorbent assay （ELISA） kit.The follow-up was performed on the 7th day,28th day,3rd month and 6th month after acute attack.According to the follow-up results we defined the end of observation as recurrence of AMI or any causes of death.Results Median sST2 level of the control group was 9.38ng/ml and that of AMI patients was 29.06ng/ml.Compared with the control group,sST2 expression in the AMI group was significantly different （P〈0.001）.In contrast,the IL-33 level showed no significant difference between the two groups.Serum sST2 was a predictive factor independent of other variables and may provide complementary information to NT-proBNP or GRACE risk score.IL-33 had no relationship to recurrence of AMI.Both sST2 and the IL-33/sST2 ratio were correlated with the 6-month prognosis; areas under the ROC curve were 0.938 and 0.920 respectively.Conclusions Early in the course （〈24 hours） of AMI,sST2 usually increases markedly.The increase of sST2 has an independent predictive value for the prognosis in AMI patients and provides complementary information to NT-proBNP or GRACE risk score.The IL-33/sST2 ratio correlates with the 6-month prognosis of AMI patients.However,there is no significant relationship between IL-33 and the prognosis of AMI patients.     

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.     

Myocardial autophagy variation during acute myocardial infarction in rats: the effects of carvedilol

Background The loss of cardiac myocytes is one of the mechanisms involved in acute myocardial infarction （AMI）-related heart failure. Autophagy is a common biological process in eukaryote cells. The relationship between cardiac myocyte loss and autophagy after AMI is still unclear. Carvedilol, a non-selective α1-and β-receptor blocker, also suppresses cardiac myocyte necrosis and apoptosis induced by ischemia. However, the association between the therapeutic effects of carvedilol and autophagy is still not well understood. The aim of the present study was to establish a rat model of AMI and observe changes in autophagy in different zones of the myocardium and the effects of carvedilol on autophagy in AMI rats. Methods The animals were randomly assigned to a sham group, an AMI group, a chloroquine intervention group and a carvedilol group. The AMI rat model was established by ligating the left anterior descending coronary artery. The hearts were harvested at 40 minutes, 2 hours, 24 hours and 2 weeks after ligation in the AMI group, at 40 minutes in the chloroquine intervention group and at 2 weeks in other groups. Presence of autophagic vacuoles （AV） in the myocytes was observed by electron microscopy. The expression of autophagy-, anti-apoptotic- and apoptotic-related proteins, MAPLC-3, Beclin-1, Bcl-xl and Bax, were detected by immunohistochemical staining and Western blotting. Results AVs were not observed in necrotic regions of the myocardium 40 minutes after ligation of the coronary artery. A large number of AVs were found in the region bordering the infarction. Compared with the infarction region and the normal region, the formation of AV was significantly increased in the region bordering the infarction （P 〈0.05）. The expression of autophagy- and anti-apoptotic-related proteins was significantly increased in the region bordering the infarction. Meanwhile, the expression of apoptotic-related proteins was significantly increased in the infarction region. In the chloroquine intervention group, a large number of initiated AVs （AVis） were found in the necrotic myocardial region. At 2 weeks after AMI, AVs were frequently observed in myocardial cells in the AMI group, the carvedilol group and the sham group, and the number of AVs was significantly increased in the carvedilol group compared with both the AMI group and the sham group （P 〈0.05）. The expression of autophagy- and anti-apoptotic-related proteins was significantly increased in the carvedilol group compared with that in the AMI group, and the positive expression located in the infarction region and the region bordering the infarction. Conclusions AMI induces the formation of AV in the myocardium. The expression of anti-apoptosis-related proteins increases in response to upregulation of autophagy. Carvedilol increases the formation of AVs and upregulates autophagy and anti-apoptosis of the cardiac myocytes after AMI.     

Huoxue Anxin Recipe(活血安心方)Promotes Myocardium Angiogenesis of Acute Myocardial Infarction Rats by Up-Regulating miR-210 and Vascular Endothelial Growth Factor

Objective: To investigate the microR NAs(miR NAs) expression profile of acute myocardial infarction(AMI) rats and the regulating effects of Huoxue Anxin Recipe(活血安心方, HAR) on angiogenesis-related miR NAs and genes. Methods: Forty-five Wistar rats were randomly assigned to 3 groups according to a random number table: sham, AMI, and AMI+HAR groups(15 in each group). AMI rats were established by ligation of the left descending coronary artery. HAR was intragastrically administered to rats of the AMI+HAR group for successive 21 days since modeling, meanwhile the same volume of 0.9% normal saline was administered to rats of the sham and AMI groups. Doppler echocardiography was used for noninvasive cardiac function test. Hematoxylin and eosin staining was used to observe the histopathological change. miR NAs expression profile was detected by quantitative realtime polymerase chain reaction(qR T-PCR). The mR NA and protein expressions of vascular endothelial growth factor(VEGF), and a target gene of miR-210 was further detected by qR T-PCR and Western blot, respectively. The microvessels density of myocardium was evaluated by CD31 immunostaining. Results: Compared with the sham group, ejection fraction(EF) and fractional shortening(FS) values were decreased significantly in the AMI group(P0.01), while the infarction area and the interstitial collagen deposition were increased obviously. As for the AMI+HAR group, EF and FS values were increased significantly(P0.05 vs. AMI group), and the infarction area was reduced and the interstitial collagen deposition were alleviated significantly. Total of 23 miR NAs in the AMI group expressed differently by at least 1.5 folds compared with those in the sham group; 5 miR NAs in the AMI+HAR group expressed differently by at least 1.5 folds compared with those in the AMI group. Among them, miR-210 was low in the AMI group and high in the AMI+HAR group. The relative mR NA and protein expressions of VEGF were decreased significantly in the AMI group(P0.05 vs. sham group), and increased significantly in the AMI+HAR group(P0.01 vs. AMI group). CD31 expression area and optical intensity were decreased significantly in the AMI group(P0.05 vs. sham group), and increased significantly in the AMI+HAR group(P0.01 vs. AMI group). Conclusions: HAR could reduce the infarction area, alleviate the interstitial fibrosis and improve the cardiac function of AMI rats. Those effects could be related to promoting myocardium angiogenesis of HAR by up-regulating miR-210 and VEGF.     

Alterations of the percentage of lymphocytes in patients with acute myocardial infarction and clinical evaluation.

In order to investigate the human immunological response to acute myocardial infarction (AMI), lymphocyte cells of peripheral vein blood withdrawn from patients with AMI were continuously and quantitatively assayed by flow cytometry method (FCM). The correlation between the alterations of immunological function and clinical course was analyzed. MATERIAL AND METHODS Thirty-one samples were collected from peripheral vein blood of hospitalized patients with AMI in the author's institution. The patients were aged from 39 to 81 years, ( 26 men and 5 women ). Samples withdrawn from 14 healthy adults served as normal control.     

THE MECHANISM OF INHIBITION OF DNA SYNTHESIS BY HHO7A, A DERIVATIVE OF HAINANENSINE

The synthesis of DNA, RNA and protein in L1210 cells was inhibited by HH07A in a dose-dependent and time dependent way. HH07A showed much stronger inhibitory effect on [^3H]-thymidine incorporation than that on [^3H]-uridine or [^3H]-tyrcsine incorporation. The methods of shift of absorption spectrum,shift of fluorescence emission spectrum and excitation spectrum, anal isotope technique were used to investigate the mechanism of action of HH07A on DNA symhesis. The results suggested that the action of HH07A on DNA synthesis was not probably due to direct damage to the DNA template, it might mainly act by interfering with the metabolism of DNA.     

Apparent protective effect of high density lipoprotein against coronary heart disease in the elderly

Background This study was designed to evaluate the relationship between high-density lipoprotein cholesterol (HDL-C) level and acute myocardial infarction (AMI) and coronary heart disease (CHD) death and to explore the protective effect of HDL against CHD in the elderly Chinese.Methods Started from 1986, 1211 retirees (92% males) were enrolled consecutively and studied prospectively. The average starting age was 70±9 years, and that at the end of the study was 80±9 years. During the follow-up study, all the participants received yearly physical examination and blood chemistry survey from 1986-2000. The average duration of the follow up study was 11.2 years. The end point of this study was either attacks of AMI or death due to CHD and other causes. CHD risk factors were screened by logistic regression analysis. According to their HDL-C levels, cases were divided into low (<1.03 mmol/L), medium (or normal, 1.03-1.56 mmol/L) and high (>1.56 mmol/L) level groups, the differences in incidence of AMI and CHD death in each group were analyzed.Results The cumulative attacks of acute coronary syndrome (mostly AMI) were 214 cases, including 89 cases of coronary death and 308 death caused by other diseases during the follow up study. AMI occurrence and CHD death in normal HDL-C group were lower than those in the low HDL-C group by 40% and 53%; and those in the high HDL-C group were lower than in the normal group by 56% and 50%, respectively. Statistical analysis on normal lipid cases （411 cases, total cholesterol<5.17mmol/L, triglyceride<1.69 mmol/L） revealed that the cases at low HDL-C level had similar rates of AMI events and CHD mortality as those of the entire group (including hyperlipidemia); however, AMI attacks and CHD deaths decreased significantly at the normal and high HDL-C levels. The results demonstrated that the protective effect of HDL against coronary artery disease is more prominent in people with low lipid level.Conclusion Low HDL is an important independent risk factor for AMI attacks and CHD death in the elderly; high HDL has significant protective effect against coronary artery disease.
