Guanxin Danshen Dripping Pills Improve Quality of Life and Cardiovascular Prognoses of CHD Patients after PCI with Anxiety or Depression (GLAD Study): A Randomized Double-Blind Placebo-Controlled Study / 中国结合医学杂志

OBJECTIVE@#To assess the efficacy and safety of Guanxin Danshen Dripping Pills (GXDS) in the treatment of depression or anxiety in patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI).@*METHODS@#From September 2017 to June 2019, 200 CHD patients after PCI with depression and anxiety were included and randomly divided into GXDS (100 cases) and placebo control groups (100 cases) by block randomization and a random number table. Patients in the GXDS and control groups were given GXDS and placebo, respectively, 0.4 g each time, 3 times daily for 12 weeks. The primary outcomes were scores of Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Scale (GAD-7) and the Seattle Angina Pectoris Scale (SAQ). The secondary outcomes included 12 Health Survey Summary Form (SF-12) scores and the first onset time and incidence of major adverse cardiovascular events (MACEs). Other indices including blood pressure, blood lipids, microcirculation and inflammatory-related indices, etc. were monitored at baseline, week 4, and week 12.@*RESULTS@#In the full analysis set (200 cases), after treatment, the PHQ-9 and GAD-7 scores in the GXDS group were considerably lower than those in the control group (P<0.05). Compared with the baseline, the total PHQ-9 scores of the experimental and control groups decreased by 3.97 and 1.18, respectively. The corrected mean difference between the two groups was -2.78 (95% CI: -3.47, -2.10; P<0.001). The total GAD-7 score in the GXDS group decreased by 3.48% compared with the baseline level, while that of the placebo group decreased by 1.13%. The corrected mean difference between the two groups was -2.35 (95% CI: -2.95, -1.76; P<0.001). The degree of improvement in SAQ score, SF-12 score, endothelin and high-sensitive C-reactive protein levels in the GXDS group were substantially superior than those in the placebo group, and the differences between the two groups were statistically significant (P<0.05). Similar results were obtained in the per protocol population analysis of 177 patients. Three cases of MACES were reported in this study (1 in the GXDS group and 2 in the placebo group), and no serious adverse events occurred.@*CONCLUSIONS@#GXDS can significantly alleviate depression and anxiety, relieve symptoms of angina, and improve quality of life in patients with CHD after PCI.

Meta-analysis and GRADE evaluation of Guanxinning Tablets in treatment of angina pectoris of coronary heart disease / 中国中药杂志

This study aims to evaluate the efficacy and safety of Guanxinning Tablets+conventional western medicine in the treatment of angina pectoris of coronary heart disease, and provide evidence-based references for clinical medication. Retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, Cochrane Library, randomized controlled trial(RCT) about Guanxinning Tablets for the treatment of angina pectoris of coronary heart disease from the inception to April 2022 were collected. After literature screening and data extraction, the bias risk assessment tool recommended by the Cochrane evaluation manual handbook 5.1.0 was used to evaluate the quality of the included literature, and RevMan 5.3 and Stata 14.0 were used for Meta-analysis. Eighteen RCTs were finally included, involving 2 281 patients. Meta-analysis showed that, compared with conventional western medicine treatment alone, Guanxinning Tablets+conventional western medicine significantly improved angina pectoris efficacy(RR=1.33, 95%CI[1.13, 1.57], P=0.000 8), electrocardiogram efficacy(RR=1.32, 95%CI[1.02, 1.71], P=0.03), and exercise duration(MD=59.53, 95%CI[39.16, 79.90], P<0.000 01) and reduced the incidence of cardiovascular events(MACE)(RR=0.43, 95%CI[0.30, 0.61], P<0.000 01), high sensitivity C-reactive protein(hs-CRP)(MD=-2.75, 95%CI[-3.71,-1.79], P<0.000 01), and endothelin-1(ET-1) levels(MD=-9.34, 95%CI[-11.36,-7.32], P<0.000 01). There was no statistically significant difference in the incidence of adverse reactions between two groups(RR=0.91, 95%CI[0.68, 1.22], P=0.52). Subgroup analysis showed that Guanxinning Tablets may have better short-term efficacy(less than 6 months) in the treatment of heart-blood stasis syndrome. GRADE grading showed that angina pectoris efficacy, electrocardiogram efficacy, MACE, and ET-1 were in the medium grade, hs-CRP and adverse reactions were in the low grade, and exercise duration was in the extremely low grade. In conclusion, the efficacy of Guanxinning Tablets+conventional western medicine is better than conventional western medicine treatment alone, with good safety. Therefore, it is recommended for the short-term treatment of patients with heart-blood stasis syndrome. However, the evidence quality of some results is low, and more rigo-rous RCT is still needed to enhance the reliability of evidence.

Risk factors related to coronary artery occlusion in female patients with ischemic angina pectoris / 中华心血管病杂志

Objective: To analyze the risk factors of coronary artery occlusion in female patients with ischemic angina pectoris. Methods: Clinical data of 1 600 patients (666 females and 934 males) who underwent coronary angiography from January 2013 to December 2015 due to angina pectoris in 6 major coronary intervention centers in China were retrospectively analyzed. The clinical characteristics were compared between the female and male groups, and between the non-obstructive coronary artery disease (INOCA) and ischemic obstructive coronary artery disease (IOCA) subgroups of female subjects with angina pectoris. The risk factors related to the degree of coronary artery occlusion in female patients were analyzed. Results: In the enrolled patients who underwent coronary angiography for angina pectoris, female group was older than the male group, and the proportion of patients with hypertension, diabetes and ischemia accompanied by IOCA was significantly higher than that of the male group (P<0.05). Univariate analysis showed that age≥65 years, hypertension, diabetes, and typical angina symptoms were associated with an increased risk of IOCA in female patients with angina pectoris. Multivariate regression analysis showed that age≥65 years old (OR=1.784, 95%CI: 1.146-2.776, P=0.010), hypertension (OR=1.782, 95%CI: 1.201-2.644, P=0.004) and typical angina symptoms (OR=1.642, 95%CI: 1.127-2.393, P=0.010) were independent risk factors for female patients with angina pectoris diagnosed as IOCA. The correlation analysis between the number of risk factors and the type of coronary artery disease obstruction showed that the incidence of INOCA decreased significantly with the increase of the number of risk factors, from 45.5% to 14.2%. The incidence of IOCA increased significantly with the number of risk factors, from 54.5% to 85.8% (P for trend<0.001). Conclusion: The incidence of INOCA in female patients with angina pectoris suspected of coronary heart disease is higher than that of male. The incidence of IOCA increased significantly, and the incidence of INOCA decreased significantly in proportion to the increase of the number of combined risk factors.

Consistency evaluation of target heart rate determined by anaerobic threshold and by resting heart rate in patients with coronary artery disease after percutaneous coronary intervention / 中华心血管病杂志

Objective: To evaluate the consistency on the determination of target heart rate by simple calculation method based on resting heart rate and by anaerobic threshold method in cardiopulmonary exercise test (CPET) for patients with coronary artery disease after percutaneous coronary intervention (PCI). Methods: This study was a diagnostic test. Patients with coronary artery disease who underwent the first PCI in the Department of Cardiology of Peking University People's Hospital from October 2011 to April 2021 were enrolled. Patients were further divided into subgroups according to gender, age (<60 years group and ≥60 years group), with or without myocardial infarction history (myocardial infarction group and angina pectoris group) and whether β blockers were applied. The general clinical data of patients, resting heart rate (RHR) and anaerobic threshold heart rate in CPET were collected through the electronic medical record system. The simple target rate (RHR plus 20 or 30 bpm) and the target rate calculated by anaerobic threshold (anaerobic threshold heart rate minus 10 bpm) were both calculated in each patient. Consistency test of target heart rate derived by above the two methods was shown by intra-class correlation (ICC) and Bland-Altman plots. Results: A total of 439 patients were included, age was (56.2±8.8) years, body mass index was (25.77±2.34) kg/m2, there were 382 males (87.0%). The target heart rate determined by anaerobic threshold method was (90.0±11.8)bpm, and the simple target heart rate determined by RHR plus 20 bpm was (91.0±8.4)bpm. There was no significant difference on the target heart rate derived from the two calculation methods (P=0.091). The simple target heart rate determined by RHR plus 30 bpm was (101.0±8.4)bpm, which was significant higher than that determined by anaerobic threshold method (P<0.001). In the following analysis, RHR plus 20 bpm was defined as the simple target heart rate. The ICC value of target heart rate determined by anaerobic threshold and resting rate plus 20 bpm was 0.529(95%CI 0.458-0.593, P<0.001). Bland-Altman plots analysis showed that the ratio of the simple target heart rate and the target heart rate determined by anaerobic threshold method was 1.03±0.11 and the 95% limits of agreement (LOA) were 0.812-1.245. In the subgroup of patients aged<60 years (n=247), the ICC value was 0.492, the ratio by Bland-Altman plots analysis was 1.02±0.11 and LOA was 0.814-1.234; in the subgroup of patients aged ≥60 years (n=192), the ICC value was 0.566, the ratio by Bland-Altman plots analysis was 1.03±0.11 and LOA was 0.810-1.260. In male subgroup(n=382), the ICC value was 0.540, the ratio by Bland-Altman plots analysis was 1.03±0.11 and LOA was 0.813-1.246; in female subgroup(n=57), the ICC value was 0.445, the ratio by Bland-Altman plots analysis was 1.03±0.11 and LOA was 0.810-1.240.In myocardial infarction subgroup (n=186), the ICC value was 0.568, the ratio by Bland-Altman plots analysis was 1.02±0.11 and LOA was 0.810-1.227; in angina pectoris subgroup (n=253), the ICC value was 0.495, the ratio by Bland-Altman plots analysis was 1.04±0.11 and LOA was 0.813-1.260. In the subgroup of patients with β blockers (n=353), the ICC value was 0.520, the ratio by Bland-Altman plots analysis was 1.03±0.11 and LOA was 0.810-1.252; in the subgroup of patients without β blockers (n=86), the ICC value was 0.570, the ratio by Bland-Altman plots analysis was 1.02±0.10 and LOA was 0.821-1.219. Conclusions: The simple target heart rate determined by RHR plus 20 bpm is consistent with the target heart rate determined by anaerobic threshold in patients with coronary artery disease after PCI. But the simple target heart rate determined by RHR plus 20 bpm can't replace the target heart rate determined by anaerobic threshold in this patient cohort.

Clinical comprehensive evaluation of Guanxin Shutong Capsules in treatment of coronary heart disease angina pectoris with heart blood stasis syndrome / 中国中药杂志

This study aims to comprehensively summarize articles on the treatment of coronary heart disease angina pectoris with heart blood stasis syndrome(CHD-AP-HBSS) by Guanxin Shutong Capsules(GSC), and comprehensively evaluate the evidence and value of the formula in "6+1" dimensions based on multi-criteria decision analysis(MCDA) model and Guidelines for Management of Comprehensive Clinical Evaluation of Drugs(trial version 2021) with quantitative and qualitative methods, which is expected to highlight the clinical characteristics and advantages of the prescription and serve as a reference for medical and health departments. The dimensions are grade A, B, C, or D. In terms of safety, according to the reports from the spontaneous reporting system of National Center for ADR Monitoring, and literature analysis, GSC mainly results in the adverse reactions of mild or moderate nausea, diarrhea, rash, palpitation, and headache, with favorable prognosis in patients. Nevertheless, severe adverse reactions have been reported after marketing. Thus, additional evidence for its safety should be accumulated, and the current safety is grade B. Meta-analysis proves that GSC in combination with conventional treatment is superior to conventional treatment alone in alleviating AP and symptoms indicated by electrocardiogram(ECG). Therefore, the effectiveness of the medicine is grade A. As for the pharmacoeconomic value, based on the assumption that the per capita disposable income in 2020 is the willingness-to-pay threshold, it is more economical for CHD-AP patients to use GSC combined with conventional treatment than conventional treatment alone. However, as the currently available clinical parameters fail to support the difference in indirect cost between the two groups, the accuracy in the cost of intervention plan needs to be further improved. Therefore, the economy of the prescription is grade B. GSC has been awarded 13 national invention patents and 1 utility model patent, and won a lot of national and provincial patent awards, marking the enterprise service awareness and innovativeness. As a result, it is grade A in aspect of innovation. A questionnaire on the suitability of GSC suggests that publicity and promotion influence patients' choice and thus additional efforts should be made in this aspect. The suitability of this formula is grade B. Both rural and urban residents can afford the medicine for the whole course and the price is close to that of similar Chinese patent medicines. In addition, it is accessible regardless of season and place, so accessibility is grade A. As a Mongolian empirical formula destined to treat heart stabbing pain, it has the effects of activating blood and resolving stasis, dredging channels and activating collaterals, and moving Qi to relieve pain, and boasts the empirical evidence of more than 2 000 human cases. With prominent characteristics of traditional Chinese medicine, it is grade B. Based on the MCDA model and CSC v2.0, GSC is comprehensively class A in the treatment of CHD-AP-HBSS. The result can serve as a reference for basic clinical medication management.

Mechanism of Syringa oblata in treating angina pectoris based on GC-MS and network pharmacology / 中国中药杂志

The chemical constituents in the volatile oil of Syringa oblata were identified using GC-MS and NIST database. TCMSP and SwissTargetPrediction were employed to predict the potential targets of the active components in S. oblata. Through Online Mendelian Inheritance in Man(OMIM), GeneCards, and Kyoto Encyclopedia of Genes and Genomes(KEGG), we screened out the targets related to the prevention or treatment of angina pectoris by the volatile oil of S. oblata, and then used DAVID 6.8 to annotate the gene ontology(GO) terms and KEGG pathways. The "active components-targets-pathways" network was constructed in Cytoscape 3.6.0, and the key active components and targets of S. oblata were verified by Discovery Studio 2016. Forty-six chemical constituents were identified from the volatile oil of S. oblata; 198 potential targets of the active components and 1 138 targets associated with angina pectoris were predicted. A total of 71 common targets were shared by the active components and the disease, including cytochrome P450 19 A1(CYP19 A1) and prostaglandin G/H synthase 2(PTGS2). The KEGG pathways involved include PPAR, JAK-STAT, TNF, Toll-like receptor and NOD-like receptor signaling pathways. The active components in the volatile oil of S. oblata may play anti-inflammatory and anti-apoptosis roles. This study provides a reliable clue for further explanation of the effective components and the functioning mechanism of S. oblata in the treatment of angina pectoris.

Screening methods of traditional Chinese medicine for coronary heart disease and angina pectoris: an exploration based on core outcome set and fuzzy comprehensive evaluation / 中国中药杂志

It was pointed out in Opinions on Promoting the Inheritance, Innovation and Development of Traditional Chinese Medicine issued by the State Council in 2019 that 100 varieties of traditional Chinese medicine(TCM) with unique curative effects should be screened out within about three years. Due to the multi-component and multi-target mechanisms of TCM varieties, it is difficult to directly and simply evaluate their multi-dimensional clinical value using methods applicable to chemical or biological agents. The heterogeneity of outcomes for similar TCM makes it difficult to determine the advantages of similar products. The fuzzy comprehensive evaluation method that is developed on the basis of core outcome set and fuzzy mathematics for clinical efficacy evaluation of TCM may solve these problems. This study developed a fuzzy comprehensive evaluation model for the clinical efficacy evaluation of Chinese patent me-dicines for coronary heart disease and angina pectoris, and selected the previous normative studies with complete or incomplete data for verifying the model application. The results showed that original studies with complete data failed to evaluate and compare the comprehensive efficacy of different interventions. The original research only mentioned the advantages and disadvantages of different interventions in different aspects. The comprehensive clinical efficacy of three different interventions obtained through fuzzy comprehensive evaluation was all graded as level Ⅱ. The original research with incomplete data drew the same conclusions as the fuzzy comprehensive evaluation, and the results of fuzzy comprehensive evaluation can provide more comprehensive information. Therefore, the fuzzy comprehensive evaluation shows the products with overall advantages of clinical efficacy, which may become a feasible method for the screening of TCM.

Prevalence of Angina Pectoris and Associated Factors in the Adult Population of Brazil: National Survey of Health, 2019 / Prevalência e fatores associados da angina do peito na população adulta do Brasil: Pesquisa Nacional de Saúde, 2019

ABSTRACT: Objective: to estimate the prevalence and factors associated with angina pectoris in the Brazilian adult population and per federated units. Methods: Cross-sectional descriptive study that analyzed data from the National Survey of Health 2019 and assessed the prevalence of angina in the Brazilian population. Angina was defined as chest pain or discomfort when climbing hills or stairs, or when walking fast on flat terrain (angina I) or when walking at normal speed on flat terrain (angina II). Prevalence, crude and adjusted prevalence ratios were calculated, with a 95% confidence interval, according to sociodemographic characteristics (sex, age group, self-reported race/skin color and region of residence) and federative units. Results: The prevalence of mild angina (grade I) was 8.1% and of moderate/severe angina (grade II) was 4.5%, being both more prevalent in women (9.8 and 5.5%, respectively). The prevalence increased progressively with age and was inversely proportional to years of formal study. Grade I angina was higher in individuals self-reportedly black and residents of Sergipe (10,4%). Angina II was more prevalent in people self-reportedly brown and living in Amazonas (6.3%). Conclusion: Angina affects more than 10% of the Brazilian population aged 18 years old and more, with higher prevalence in states in the North and Northeast. This is a problem that affects the most vulnerable populations unequally, which places coronary heart disease as a public health problem and points to the need to think about public policies aimed at these strata of the population.

RESUMO: Objetivo: Estimar a prevalência e fatores associados à angina do peito na população adulta brasileira e por unidades federadas. Métodos: Estudo transversal descritivo, que analisou os dados da Pesquisa Nacional de Saúde 2019 e avaliou a angina na população brasileira. A angina foi definida como dor ou desconforto no peito ao subir ladeiras ou um lance de escadas, ou ao caminhar rapidamente no plano (angina I) ou em velocidade normal no plano (angina II). Foram calculadas as prevalências, razão de prevalência bruta e ajustada, com intervalo de confiança de 95%, segundo características sociodemográficas (sexo, faixa etária, raça/cor da pele autodeclarada e região de moradia) e unidades federativas. Resultados: A prevalência de angina leve (grau I) foi de 8,1% e da angina moderada/grave (grau II), 4,5%, ambas mais prevalentes em mulheres (9,8 e 5,5%, respectivamente). As prevalências aumentaram progressivamente com o avanço da idade e foram inversas aos anos de estudo formal. Angina grau I foi mais elevada em indivíduos da raça/cor da pele autodeclarada preta e residentes em Sergipe (10,4%). A angina II foi mais prevalente em pessoas de raça/cor da pele autodeclarada parda, que vivem no Amazonas (6,3%). Conclusão: A angina afeta mais de 10% da população brasileira acima de 18 anos, com maior prevalência em estados do Norte e do Nordeste. É um agravo que atinge de forma desigual as populações mais vulneráveis, revelando a importância da doença coronariana como problema de saúde pública e a necessidade de pensar em políticas públicas voltadas para esses estratos da população.

Aspirin plus verapamil relieves angina and perfusion abnormalities in patients with coronary microvascular dysfunction and Chagas disease: a pilot non-randomized study

Abstract INTRODUCTION: Most patients with chronic cardiomyopathy of Chagas disease (CCCD) harbor a secondary cause of coronary microvascular dysfunction (CMD), for which there is no evidence-based therapy. We evaluated the impact of verapamil plus aspirin on symptoms and perfusion abnormalities in patients with CCCD and CMD. METHODS: Consecutive patients with angina pectoris, who had neither coronary artery obstructions nor moderate-severe left ventricular dysfunction (left ventricular ejection fraction > 40%) despite showing wall motion abnormalities on ventriculography, were referred for invasive angiography and tested for Chagas disease. Thirty-two patients with confirmed CCCD and ischemia on stress-rest SPECT myocardial perfusion scintigraphy (MPS) were included. Clinical evaluation, quality of life (EQ-5D/ Seattle Angina Questionnaire), and MPS were assessed before and after 3 months of treatment with oral verapamil plus aspirin (n=26) or placebo (n=6). RESULTS: The mean patient age was 64 years, and 18 (56%) were female. The ischemic index summed difference score (SDS) in MPS was significantly reduced by 55.6% after aspirin+verapamil treatment. A decrease in SDS was observed in 20 (77%) participants, and in 10 participants, no more ischemia could be detected. Enhancements in quality of life were also detected. No change in symptoms or MPS was observed in the placebo group. CONCLUSIONS: This low-cost 3-month treatment for patients diagnosed with CCCD and CMD was safe and resulted in a 55.6% reduction in ischemic burden, symptomatic improvement, and better quality of life.

Overview of systematic reviews on Shuxuening Injection / 中国中药杂志

This study aimed to analyze the methodological quality of systematic reviews of Shuxuening Injection and evaluate the efficacy and adverse reactions of Shuxuening Injection in the treatment of different diseases,in order to provide supportive evidence for clinical practice. Three Chinese databases and three English databases were retrieved to identify systematic reviews and Meta-analysis on the efficacy and safety of Shuxuening Injection in the treatment of diseases. The AMSTAR 2( a measurement tool to assess systematic reviews 2) tool was used to evaluate the methodological quality of the included systematic reviews,and tables were created to present the results of Meta-analyses. Twenty-four systematic reviews were included,all with very low methodological quality. Among the 16 AMSTAR-2 items,only 5 items had a compliance rate greater than 60. 0%,and 8 items had a compliance rate less than 50. 0%. For patients with cerebral infarction,Shuxuening Injection combined with conventional treatment was more effective than conventional treatment alone in terms of clinical efficiency and neurological deficit improvement. For patients with angina pectoris,Shuxuening Injection was superior to Danshen/Compound Danshen Injection in terms of the total effective rate of angina pectoris and total effective rate of ECG. The efficacy of Shuxuening Injection combined with conventional treatment is significantly better than conventional treatment.Shuxuening Injection( alone or combined with conventional treatments) was better than conventional treatments for cerebral hemorrhage,ischemic cerebrovascular disease,chronic pulmonary heart disease,vertigo and sudden deafness. Shuxuening Injection had better efficacy and lower incidence of adverse reactions,but the methodological quality of included systematic reviews was low. The results of this study still need to be verified by high-quality systematic reviews.

The present study evaluated the curative efficacy of Chinese herbal injection on unstable angina pectoris( UAP) by network Meta-analysis. The databases,including Pub Med,Cochrane Library,Web of Science,CNKI,CBM,VIP and Wanfang were searched for randomized controlled trial( RCT) of Chinese herbal injection in the treatment of UAP. All researchers independently screened the articles,extracted the data and evaluated the quality. Open BUGS and Stata were employed for the analysis of the trials that met the quality standards. Fifty-eight studies were finally included in this study,involving 20 intervention measures. In terms of the effective rate,16 injections such as Dengzhan Xixin Injection,Xuesaitong Injection and Danshen Injection combined with western medicine exhibited significant efficacy. In terms of ECG,Puerarin Injection,Ginkgo Leaf Extract and Dipyridamole Injection( GDI),Breviscapine Injection combined with western medicine were superior to western medicine. In terms of the reduction of the angina attack times,Sodium Tanshinone ⅡASulfonate Injection,GDI and Dazhu Hongjingtian Injection combined with western medicine showed better effects than western medicine. In terms of shortening the angina duration,Shenmai Injection combined with western medicine was superior to western medicine. As revealed by the results,Dengzhan Xixin Injection,Xuesaitong Injection,Danshen Injection,Breviscapine Injection,Danshen Ligustrazine Injection combined with western medicine displayed prominent curative efficacy,which were recommended for clinical application. Meanwhile,appropriate intervention measures should be selected according to individual conditions. Limited by the quality of the included trials,the conclusions still need to be further verified.

Acupuncture combined with western medication in treatment of type 2 diabetes mellitus with angina pectoris of coronary heart disease: a randomized controlled study / 中国针灸

OBJECTIVE@#To compare the therapeutic effect on type 2 diabetes mellitus (T2DM) complicated with angina pectoris of coronary heart disease between the combined therapy of acupuncture and western medication and the simple administration of western medication.@*METHODS@#A total of 134 patients with T2DM and angina pectoris of coronary heart disease were randomly divided into two groups, i.e. an acupuncture plus medication group (67 cases, 3 cases dropped off) and a medication group (67 cases, 4 cases dropped off). The routine western medication was used according to symptoms in the patients of both groups. In the acupuncture plus medication group, on the base of medication, acupuncture was applied to Jianshi (PC 5), Quchi (LI 11), Neiguan (PC 6), etc. The needles were retained for 20 min in each treatment and 3 treatments of acupuncture were required weekly. The treatment was given consecutively for 8 weeks in the two groups. Separately, before and after treatment, the symptom scores of TCM were observed and the indexes were detected, including glycolipid metabolism [fasting plasma glucose (FPG), 2-h plasma glucose (2hPG), glucosylated hemoglobin (HbA1c), triacylglycerol (TG) and total cholesterol (TC)], islet β cell function [homeostasis model assessment-β (HOMA-β), homeostasis model assessment-IR (HOMA-IR), fasting insulin (FINS) and insulin sensitivity index (ISI)], cardiac function indexes [cardiac output (CO), early diastolic peak velocity/late diastolic peak velocity (E/A), left ventricular end diastolic diameter (LVEDD) and left ventricular ejection fraction (LVEF)], as well as electrocardiogram QT dispersion (QTd). Besides, the clinical therapeutic effects were compared between the two groups.@*RESULTS@#After treatment, the TCM symptom scores and the values of FPG, 2hPG, HbA1c, TG, TC, HOMA-IR, FINS, E/A and LVEDD as well as QTd were all lower than those before treatment in the two groups (@*CONCLUSION@#The combined therapy of acupuncture and medication is effective in treatment of T2DM complicated with angina pectoris of coronary heart disease. Such therapy effectively improves glucolipid metabolism, islet β cell function, cardiac function and myocardial blood supply. Its curative effect is better than the simple administration of western medicine.

Clinical value of TDI combined with 2D-STI on evaluating the microcirculation dysfunction and left ventricular dysfunction in patients with non-obstructive coronary angina / 中华心血管病杂志

Objective: To explore the value of tissue Doppler imaging (TDI) combined with two-dimensional speckle tracking imaging (2D-STI) at rest on evaluating microcirculation dysfunction and left ventricular dysfunction in patients with angina and no obstructive coronary artery disease(ANOCA). Methods: This retrospective study recruited 78 ANOCA patients, who hospitalized in the People's Hospital of Liaoning Province from August 2019 to July 2021. These patients underwent conventional echocardiography examination, including TDI and 2D-STI, to evaluate the left ventricular dysfunction, and adenosine stress echocardiography (SE) to evaluate the coronary flow velocity reserve (CFVR). ANOCA patients were divided into coronary microcirculation dysfunction CMD group (CFVR<2) and control group (CFVR≥2) according to CFVR. Clinical data, routine echocardiographic parameters, TDI parameters including isovolumic contraction time (IVCT), isovolumic relaxation time (IVRT), ejection time (ET), and STI parameters including global longitudinal peak strain (GLS), time to peak (TTP); peak strain dispersion (PSD) were compared between the two groups. Binary logistic regression was used to analyze the risk factors of CMD and the predictive value of each parameter to construct a joint prediction model for the diagnosis of CMD in this patient cohort. Results: The mean age was (55.5±11.2) years, 43 (55%) patients were females in this patient cohort, 38 (49%) patienst were didvided into the CMD group and 40 (51%) into the control group. Age, prevalence of hypertension, diabetes, dyslipidemia, and smokers were significantly higher in the CMD group than in the control group (all P<0.05). Tei index was higher, IVCT and TTP were longer, PSD was higher, ET was shorter, and absolute GLS was lower in the CMD group than in the control group (all P<0.05). The results of logistic regression analysis showed that longer IVCT, higher Tei index, higher time to PSD and lower absolute GLS were the independent risk factors of CMD. The ROC curve revealed that the predicting efficacy on CMD was satisfactiory with the combined predictors: AUC=0.884, sensitivity of 82% and specificity of 80%. Conclusions: TDI combined with 2D-STI is associated with a good diagnostic value on the diagnosis of CMD and left ventricular dysfunction in patients with ANOCA, which provides a feasible non-invasive tool for the diagnosis of CMD and risk stratification of patients with ANOCA.

Combination of Activating Blood Circulation and Detoxifying Chinese Medicines Played an Anti-Inflammatory Role in Unstable Angina Patients after Percutaneous Coronary Intervention: A Multicenter, Open-Labeled, Randomized Controlled Trial / 中国结合医学杂志

OBJECTIVE@#To investigate the combined anti-inflammatory effect of activating blood circulation and detoxifying Chinese medicines in unstable angina (UA) patients.@*METHODS@#This study was an open-labeled, randomized controlled trial conducted in 5 centers in Beijing. A total of 154 patients were randomized into two groups at a 1:1 ratio by random numbers. Based on the conventional treatment, patients in the activating blood circulation (ABC) group were treated with Guanxin Danshen Droping Pill (, 0.4 g, thrice daily), and patients in the activating blood circulation and detoxifying (ABCD) group were treated with Guanxin Danshen Droping Pill (0.4 g, thrice daily) and Andrographis tablet (0.2 g, thrice daily) for 4 weeks. The primary outcome was the serum level of high sensitive C reaction protein (hs-CRP), and the secondary outcome index included the serum levels of tumor necrosis factor α (TNF-α), interleukin 6 (IL-6), soluble CD40 ligand (sCD40L), thrombomodulin (TM), the score of angina pectoris, the score of blood stasis syndrome, and the score of Chinese medicine symptoms, observed at week 0 and week 4.@*RESULTS@#A total of 144 patients completed the trial (ABC group, n=70; ABCD group, n=74). There were no significant differences in the clinical baseline characteristics between the two groups. When compared with the ABC group, ABCD group showed better performance in reducing the level of inflammatory factors, especially hs-CRP (P<0.05), IL-6 (P<0.01) and TNF-α (P<0.01). In term of clinical symptoms, ABCD group played a better role in improving the scores of angina pectoris and blood stasis syndrome than ABC group (all P<0.05).@*CONCLUSIONS@#The combination of Guanxin Danshen Dropping Pill and Andrographis tablet exert significant anti-inflammatory effect on UA patients, which is superior to single Guanxin Danshen Dropping Pill.

Clinical comprehensive evaluation of Naoxintong Capsules in treatment of cerebral infarction with Qi deficiency and blood stasis syndrome and coronary heart disease angina pectoris / 中国中药杂志

Through investigating the current research on the effect of Naoxintong Capsules in the treatment of cerebral infarction with Qi deficiency and blood stasis syndrome and coronary heart disease angina pectoris, this study conducted a clinical comprehensive evaluation in "6+1" dimensions [safety, effectiveness, economy, innovation, suitability, accessibility, and characteristics of traditional Chinese medicine(TCM)], so as to highlight the advantages and clinical value of Naoxintong Capsules. By combining qualitative and quantitative methods, we used the multi-criteria decision analysis(MCDA) model to measure each dimension, and the results thereby were divided into four grades of A, B, C, and D in high-to-low order. Through literature review and evaluation, the adverse effects of Naoxintong Capsules are mainly caused by the gastrointestinal system. Since the safety risk is controllable based on current research, the safety evaluation is grade B. The effectiveness of Naoxintong Capsules combined with conventional western medicine in the treatment of cerebral infarction with Qi deficiency and blood stasis syndrome and coronary heart disease angina pectoris is evaluated as grade A, as compared with conventional therapy alone. The economy of Naoxintong Capsules, compared with Tongxinluo Capsules, is assessed as grade B. According to literature reports, Naoxintong Capsules exhibits outstanding clinical innovation in optimizing the current anti-platelet therapy strategy for patients with coronary heart disease after percutaneous coronary intervention(PCI), and the innovation is class A. Given the capsule formulation is convenient for storage and transportation, and its usage is easy for patients to grasp and accept, the suitability is grade B. The accessibility is grade A considering the price level, availability, and affordability, and the characteristics of TCM are evaluated as grade A from the perspectives of theoretical characteristics and human experience. The results of the comprehensive drug evaluation showed that the clinical value of Naoxintong Capsules is class A for treating cerebral infarction with Qi deficiency and blood stasis syndrome and coronary heart disease angina pectoris. According to the Guidelines for the Management of Comprehensive Clinical Evaluation of Drugs(trial 2021 version) issued by the National Health Commission, relevant policy results for basic clinical drug management can be formulated directly by procedure.

Meta-analysis of efficacy and safety of Shexiang Tongxin Dripping Pills combined with conventional therapy of coronary heart disease / 中国中药杂志

The aim of the research was to evaluate the efficacy and safety associated with Shexiang Tongxin Dropping Pills combined with conventional therapy for patients with coronary heart disease(CHD). We searched 8 electronic databases up to November 2020, including PubMed, Cochrane Library, EMbase, Web of Science, CNKI, Wanfang, VIP and SinoMed. Eligible studies were clinical trials of Shexiang Tongxin Dropping Pills combined with conventional therapy used in the treatment of coronary heart disease(CHD). The Meta-analysis was performed using STATA 15 software. A total of 21 RCTs(n=2 186) were shortlisted for the Meta-analysis. The results of efficacy evaluation showed that the total effective rate of Shexiang Tongxin Dropping Pills combined with conventional therapy was higher than that of conventional therapy of coronary heart disease(RR=1.20, 95%CI[1.15, 1.26], Z=8.63, P<0.001). Furthermore, Shexiang Tongxin Dripping Pills combined with conventional therapy had better effect on electrocardiogram efficacy(RR=1.24, 95%CI[1.16, 1.34], Z=5.98, P<0.001) and the number of angina attacks(SMD=-2.30, 95%CI[-3.47,-1.14], Z=3.88, P<0.001), the duration of angina attack(SMD=-2.31, 95%CI[-3.07,-1.55], Z=5.97, P<0.001), with lower levels of LDL-C(SMD=-0.73, 95%CI[-1.32,-0.14], Z=2.42, P=0.016), TC(SMD=-1.16, 95%CI[-1.35,-0.96], Z=11.56, P<0.001) and TG(SMD=-0.87, 95%CI[-1.06,-0.68], Z=8.97, P<0.001), and higher levels of HDL-C(SMD=0.87, 95%CI[0.02, 1.71], Z=2.00, P=0.045). The results of safety evaluation showed that the incidence of adverse reactions of Shexiang Tongxin Dropping Pills combined with conventional therapy was lower than that of conventional therapy of coronary heart disease(RR=0.45, 95%CI[0.22, 0.91], Z=2.23, P=0.026). There were significant differences in the above outcome indexes between the two groups. After the Harbord method test, the total effective rate outcome index has publication bias, but the sensitivity analysis of the cut-and-fill method suggested that the result was stable. In general, limited by the quantity and quality of included literature, more high-quality studies are needed to further verify the conclusions of this study.

Systematic evaluation on efficacy and safety of Gingko Ketone Ester Dropping Pills in treatment of angina pectoris and coronary heart disease / 中国中药杂志

To systemically evaluate the efficacy and safety of Gingko Ketone Ester Dropping Pills in treating angina pectoris and co-ronary heart disease. CNKI, Wanfang, SinoMed, PubMed, Cochrane Library and EMbase databases were retrieved on computer, and the randomized clinical trial(RCT) on Gingko Ketone Ester Dropping Pills in treating angina pectoris and coronary heart disease, which were published from the database establishment to December 31, 2019, were comprehensively collected. Literature screening, data extraction and quality evaluation were conducted independently by two researchers according to inclusion and exclusion criteria. Literature methodology quality evaluation was conducted with use of the Cochrane Handbook 5.3.0(bias risk assessment tool). Meta-analysis was performed with RevMan 5.3.0 software. A total of 10 RCTs were included. The results of the Meta-analysis showed that as compared with conventional Western medicine alone, the application of Gingko Ketone Ester Dropping Pills combined with conventional Western medicine treatment further improved the total effective rate and electrocardiogram effect(RR=1.43,95%CI[1.20,1.71],P<0.000 1). There were statistically significant differences in the number of angina attacks, the duration of angina and the amount of nitroglycerin used. In terms of safety indicators, four studies reported adverse reactions in the experimental group, including facial flu-shing, tachycardia, dizziness, dyspnea, nausea and other symptoms. Based on the existing findings, in the treatment of angina pectoris and coronary heart disease, Gingko Ketone Ester Dropping Pills combined with conventional Western medicine can improve the clinical total effective rate, electrocardiogram effect, number of angina attacks, duration of angina and the amount of nitroglycerin used. However, in the included studies, due to some methodological quality problems which would impact the reliability of literature results more high-quality randomized controlled trials are still needed for further verification.

Meta-analysis of Danhong Injection in treatment of diabetes mellitus complicated with coronary heart disease / 中国中药杂志

To systematically evaluate the clinical efficacy and safety of Danhong Injection combined with conventional therapy in improving diabetes mellitus complicated with coronary heart disease. Based on the online literature database(CNKI, Wanfang, VIP, PubMed, Web of Science, Cochran Library), the Chinese and English papers about the randomized controlled trial(RCT) of Danhong Injection in the treatment of diabetes mellitus complicated with coronary heart disease were searched comprehensively from the establishment of the databases to January 1, 2020. The papers were screened strictly according to the inclusion and exclusion criteria. Based on Jadad scale, the risk assessment of literature was carried out, and Meta-analysis was performed by STATA 12.0 software. Seventeen RCTs were included, involving 1 453 patients. The results of Meta-analysis showed that the combination of Danhong Injection and conventio-nal treatment could improve the clinical comprehensive effective rate(RR=1.47, 95%CI[1.38, 1.58], P<0.000 1), electrocardiogram(ECG) efficiency(RR=1.30, 95%CI[1.16, 1.46], P<0.000 1), efficiency of the angina pectoris(RR=1.41, 95%CI[1.25, 1.58], P<0.000 1), cholesterol level(SMD=-1.05, 95%CI[-1.95,-0.16], P=0.02), low-density lipoprotein(LDL) level(SMD=-0.50, 95%CI[-0.79,-0.21], P<0.000 1), coronary angina attack frequency(SMD=-3.71, 95%CI[-4.05,-3.36], P<0.000 1) and duration of angina pectoris(SMD=-2.96, 95%CI[-3.25,-2.66], P<0.000 1), with statistically significant differences. But the differences in fasting plasma glucose(FPG)(SMD=-0.19, 95%CI[-0.45, 0.08], P=0.16), plasma glucose of two hours after meal(2 hPG)(SMD=0.19, 95%CI[-0.11, 0.49], P=0.22), and high-density lipoprotein(HDL) level(SMD=0.10, 95%CI[-0.30, 0.49], P=0.62) after treatment were not statistically significant. Compared with the control group, there was no significant difference in adverse reactions(SMD=-2.96, 95%CI[-3.25,-2.66], P=0.75). The existing evidence shows that the combination of Western medicine and Danhong Injection can improve the clinical effect for diabetes mellitus complicated with coronary heart disease and has no obvious adverse reactions. However, due to the low level of overall literature evidence, high risk and some kind of publication bias, it still needs more high-quality randomized controlled trials and low-bias studies for further verification.
