ABSTRACT

Abstract The present study was designed to evaluate the strength of association of raised plasma homocysteine concentration as a risk factor for coronary heart disease independent of conventional risk factor. It was a case control study conducted at Punjab Institute of Cardiology Lahore. A total of 210 subjects aged 25 to 60 years comprising of 105 newly admitted patients of CHD as cases and 105 age and sex matched healthy individuals with no history of CHD as control were recruited for the study. Fasting blood samples were obtained from cases and controls. Plasma homocysteine was analyzed by fluorescence polarization immunoassay (FPIA) method on automated immunoassay analyzer (Abbott IMX). Total cholesterol, triglyceride and HDL cholesterol were analyzed using calorimetric kit methods. The concentration of LDL cholesterol was calculated using Friedewald formula. The patients were also assessed for traditional risk factors such as age, sex, family history of CVD, hypertension, smoking and physical activity, and were compared with control subjects. The collected data was entered in SPSS version 24 for analysis and interpretation.The mean age in controls and experimental groups were 43.00± 8.42 years and 44.72± 8.59 years with statistically same distribution (p- value= 0.144). The mean plasma homocysteine for cases was 22.33± 9.22 µmol/L where as it was 12.59±3.73 µmol/L in control group. Highly significant difference was seen between the mean plasma level of homocysteine in cases and controls (p˂0.001).Simple logistic regression indicates a strong association of coronary heart disease with hyperhomocysteinemia (OR 7.45), which remained significantly associated with coronary heart disease by multivariate logistic regression (OR 7.10, 95%C1 3.12-12.83, p=0.000). The present study concludes that elevated levels of Plasma homocysteine is an independent risk factor for coronary heart disease independent of conventional risk factors and can be used as an indicator for predicting the future possibility for the onset of CVD.


Resumo O presente estudo foi desenhado para avaliar a força da associação da concentração elevada de homocisteína no plasma como um fator de risco para doença cardíaca coronária independente do fator de risco convencional. Foi um estudo de caso-controle realizado no Punjab Institute of Cardiology Lahore. Um total de 210 indivíduos com idade entre 25 e 60 anos, compreendendo 105 pacientes recém-admitidos de CHD como casos e 105 indivíduos saudáveis ​​pareados por idade e sexo sem histórico de CHD como controle, foi recrutado para o estudo. Amostras de sangue em jejum foram obtidas de casos e controles. A homocisteína plasmática foi analisada pelo método de imunoensaio de polarização de fluorescência (FPIA) em analisador de imunoensaio automatizado (Abbott IMX). Colesterol total, triglicerídeos e colesterol HDL foram analisados ​​usando métodos de kit calorimétrico. A concentração de colesterol LDL foi calculada pela fórmula de Friedewald. Os pacientes também foram avaliados para fatores de risco tradicionais, como idade, sexo, história familiar de DCV, hipertensão, tabagismo e atividade física, e foram comparados com indivíduos de controle. Os dados coletados foram inseridos no SPSS versão 24 para análise e interpretação. A média de idade nos grupos controles e experimentais foi de 43,00 ± 8,42 anos e 44,72 ± 8,59 anos com distribuição estatisticamente igual (p-valor = 0,144). A homocisteína plasmática média para os casos foi de 22,33 ± 9,22 µmol / L, enquanto no grupo controle foi de 12,59 ± 3,73 µmol / L. Diferença altamente significativa foi observada entre o nível plasmático médio de homocisteína em casos e controles (p ˂ 0,001). A regressão logística simples indica uma forte associação de doença cardíaca coronária com hiper-homocisteinemia (OR 7,45), que permaneceu significativamente associada com doença cardíaca coronária por multivariada regressão logística (OR 7,10, 95% C1 3,12-12,83, p = 0,000). O presente estudo conclui que níveis elevados de homocisteína plasmática são fator de risco independente para doença cardíaca coronária, independentemente dos fatores de risco convencionais, e pode ser usado como um indicador para prever a possibilidade futura de aparecimento de DCV.

ABSTRACT

Abstract Coronary heart disease (CHD) has been associated with significant morbidity and mortality worldwide. Although remain controversial, several studies have demonstrated the association of M. pneumoniae infections with atherosclerosis. We evaluated the possible association of mycoplasma infections in patients diagnosed with atherosclerosis by ELISA and PCR methods. Atherosclerotic tissue samples and blood samples were collected for the detection of mycoplasma antibodies (IgA) by ELISA from the 97 patients with coronary artery disease (CAD). M. pneumoniae specific IgA, IgG and IgM were measured by using the Anti-M. pneumoniae IgA/IgG/IgM ELISA. Detection of M. pneumoniae targeting the P1 adhesion gene was performed by PCR Acute infection of M. pneumoniae was diagnosed in 43.3% (42) of patients by PCR. The M. pneumoniae specific antibodies were detected in 36.1% (35) of patients. Twenty-five (25.8%) cases had IgG antibodies, 15 (15.5%) cases had IgM antibodies, 3 (3.1%) cases had IgA antibodies, 10 (10.3%) cases had both IgM + IgG antibodies and 1 (1%) case of each had IgM + IgA and IgG + IgA antibodies. None of the cases was positive for all three antibodies. A Pearson correlation coefficient analysis revealed an excellent correlation between the PCR and the serological results (r=0.921, p<0.001). A majority (17, 40.5%) of the M. pneumoniae positive patients are within the 41-50 years of age group, followed by 10 (23.8%) patients in the age group of 61-70 years and 2 (4.8%) patients were >70 years of age. Our study reported an unusually higher prevalence of M. pneumoniae by serological tests (36.1%) and PCR (43.3%). Although the hypothesis of the association of M. pneumoniae and CAD is yet to be proven, the unusually high prevalence of M. pneumoniae in CAD patients indicates an association, if not, in the development of atherosclerosis.


Resumo A doença coronariana (DCC) tem sido associada a significativa morbidade e mortalidade em todo o mundo. Embora ainda sejam controversos, vários estudos têm demonstrado a associação de infecções por M. pneumoniae com aterosclerose. Avaliamos a possível associação de infecções por micoplasma em pacientes com diagnóstico de aterosclerose pelos métodos ELISA e PCR. Amostras de tecido aterosclerótico e amostras de sangue foram coletadas para a detecção de anticorpos contra micoplasma (IgA) por ELISA de 97 pacientes com doença arterial coronariana (DAC). IgA, IgG e IgM específicos para M. pneumoniae foram medidos usando o Anti-M. pneumoniae IgA / IgG / IgM ELISA. A detecção de M. pneumoniae visando o gene de adesão P1 foi realizada por PCR. A infecção aguda por M. pneumoniae foi diagnosticada em 43,3% (42) dos pacientes pela PCR. Os anticorpos específicos para M. pneumoniae foram detectados em 36,1% (35) dos pacientes. Vinte e cinco (25,8%) casos tinham anticorpos IgG, 15 (15,5%) casos tinham anticorpos IgM, 3 (3,1%) casos tinham anticorpos IgA, 10 (10,3%) casos tinham anticorpos IgM + IgG e 1 (1%) caso de cada um tinha anticorpos IgM + IgA e IgG + IgA. Nenhum dos casos foi positivo para os três anticorpos. A análise do coeficiente de correlação de Pearson revelou uma excelente correlação entre o PCR e os resultados sorológicos (r = 0,921, p < 0,001). A maioria (17, 40,5%) dos pacientes positivos para M. pneumoniae está na faixa etária de 41-50 anos, seguida por 10 (23,8%) pacientes na faixa etária de 61-70 anos e 2 (4,8%) pacientes tinham > 70 anos de idade. Nosso estudo relatou uma prevalência incomumente maior de M. pneumoniae por testes sorológicos (36,1%) e PCR (43,3%). Embora a hipótese da associação de M. pneumoniae e DAC ainda não tenha sido comprovada, a prevalência incomumente alta de M. pneumoniae em pacientes com DAC indica uma associação, se não, no desenvolvimento de aterosclerose.

ABSTRACT

@#Objective    To evaluate the short- and mid-term outcomes of sequential anastomosis and simple anastomosis of saphenous vein in off-pump coronary artery bypass grafting. Methods    The clinical data of 438 patients who underwent sequential anastomosis of saphenous vein and 165 patients who underwent simple anastomosis of saphenous vein from 2015 to 2018 in Daxing Teaching Hospital were retrospectively analyzed. After propensity score matching, 130 pairs of patients were included in the sequential anastomosis group [78 males and 52 females, aged 60 (52, 68) years] and simple anastomosis group [80 males and 50 females, aged 61 (52, 70) years]. The short- and mid-term clinical outcomes were compared. Results    The two propensity score-matched groups had similar baseline clinical data. No significant difference was found between sequential anastomosis and simple anastomosis groups in the in-hospital outcomes, including in-hospital death (1.5% vs. 1.5%, P=1.000), the incidence of complications (4.6% vs. 6.2%, P>0.05), and the mean flow of grafts (30.0±11.8 mL/min vs. 28.0±9.5 mL/min, P=0.597). The operation time of the sequential anastomosis group was shorter than that of the simple anastomosis group (142.5±21.2 min vs. 186.3±27.6 min, P<0.001). The drainage of the sequential anastomosis group was less than that of the simple anastomosis group (204.7±39.6 mL vs. 271.3±48.3 mL, P<0.001). The follow-up time was 12-60 (28.3±8.9) months, during which the mortality of the two groups was not statistically different (3.2% vs. 4.0%, P=0.796). Conclusion    The saphenous vein sequential anastomosis of saphenous vein is superior to the simple anastomosis. Sequential anastomosis technique can reduce aortic anastomosis,  shorten operation time, and reduce bleeding drainage during off-pump coronary artery bypass grafting. The short- and mid- term clinical effects are satisfactory.

ABSTRACT

La enfermedad cardiovascular (ECV) es una de las principales causas de morbi-mortalidad a nivel mundial y produce un enorme gasto económico en la sociedad. Hay múltiples factores de riesgo cardiovascular (CV), entre ellos: el tabaco, la obesidad, la hipertensión arterial, el colesterol y la diabetes mellitus (DM). Esta última se considera como un factor independiente para el desarrollo de ECV y de insuficiencia cardíaca (IC). Como la prevalencia de la DM se va incrementando en el mundo; así lo hace, paralelamente a la IC. Se ha demostrado en estudios preclínicos y clínicos que metformina, un fármaco antidiabético, reduce los eventos CV en los pacientes con DM. La creciente evidencia sugiere que metformina tiene un efecto protector sobre la arteria coronaria más allá de sus efectos hipoglucémicos. Dada su disponibilidad global, vía de administración y costo, metformina proporciona una opción terapéutica alternativa y adicional para la prevención primaria y secundaria de la ECV en DM y no diabéticos por igual. Es una medicación segura con efectos beneficiosos sobre la HbA1c, sobre la reducción de peso y además no produce hipoglucemia cuando es usada como monoterapia. También se sabe que metformina podría tener beneficio terapéutico tanto en la IC con FEVI preservada como en la IC con FEVI reducida. El objetivo de esta revisión es demostrar los beneficios de metformina en la reducción de la ECV, además confirmar su seguridad y protección a nivel CV.


Cardiovascular disease (CVD) is one of the main causes of morbidity and mortality worldwide and produces an enormous economic expense in society. There are multiple cardiovascular (CV) risk factors, including: tobacco, obesity, arterial hypertension, cholesterol, and diabetes mellitus (DM). The latter is considered an independent factor for the development of CVD and heart failure (HF). As the prevalence of DM is increasing in the world; it does so, in parallel with the HF. Metformin, an antidiabetic drug, has been shown in preclinical and clinical studies to reduce CV events in patients with DM. Growing evidence suggests that metformin has a protective effect on the coronary artery beyond its hypoglycemic effects. Given its global availability, route of administration, and cost, metformin provides an additional and alternative therapeutic option for the primary and secondary prevention of CVD in DM and non-diabetics alike. It is a safe medication with beneficial effects on HbA1c, on weight reduction and also does not produce hypoglycemia when used as monotherapy. It is also known that metformin could have therapeutic benefit in both HF with preserved LVEF and HF with reduced LVEF. The objective of this review is to demonstrate the benefits of metformin in reducing CVD, in addition to confirming its safety and protection at the CV level.

ABSTRACT

Objective:To investigate the correlation between gamma-glutamyl transferase/high-density lipoprotein cholesterol ratio (GHR), neutrophil/lymphocyte ratio (NLR) and coronary heart disease (CHD), and evaluated its pathogenic risk and predictive value for CHD.Methods:A total of 694 patients admitted to our hospital from December 2017 to December 2018 for suspected CHD and coronary angiography were selected. According to the results of coronary angiography,the patients were divided into CHD group ( n=527) and non-CHD group ( n=167). The clinical data of all patients were recorded. Gamma-glutamyl transferase (GGT), high-density lipoprotein cholesterol (HDL-C) and other biochemical indicators were recorded. Neutrophils, lymphocyte count and other hematological indicators were recorded. GHR, NLR and Gensini scores of the patients were calculated. Clinical data and GHR, NLR and other indicators were compared between the two groups. Receiver operating characteristic curve (ROC) was used to evaluate the predictive value of GHR, NLR in CHD, and to determine the optimal cut-off value; Logstic regression analysis was used to investigate the risk factors of CHD.Spearman correlation analysis was used to analyze the correlation between serum OPN, OPG and Gensini score in patients with CHD. Results:The GHR and NLR were 32.59(21.05, 48.24) and 3.53(2.18, 8.46) significantly higher in the CHD group than in the non-CHD group 16.56(10.07, 25.21) and 2.20(1.45, 3.28) respectively, with statistically significant differences ( Z=11.094, 9.055, P<0.05). ROC curve analysis showed that the AUC of NLR and MLR in diagnosing CHD was 0.785 and 0.732( P<0.05). When the critical values of GHR and NLR respectively were 19.805 and 2.678, respectively, the diagnostic efficiency of CHD was the highest, and the sensitivity and specificity were 79.30%, 62.90% and 63.80%, 68.30%, and the AUC of GGT in diagnosing CHD was 0.628. When the critical value was 19.500, the sensitivity and specificity were 80.50% and 39.50%, respectively,the AUC of GHR was greater than that of GGT ( Z=12.973, P<0.05). Multivariate Logistic regression analysis showed that Smoking ( OR=2.887, 95% CI:1.850-4.505, P<0.05), hypertension ( OR=2.009, 95% CI: 1.311-3.080, P<0.05), fasting plasma glucose ( OR=1.109, 95% CI:1.034-1.189, P<0.05), age ≥60 years ( OR=1.567, 95% CI:1.179-2.415, P<0.05), NLR ≥2.687 ( OR=3.152, 95% CI:2.066-4.808, P<0.05) and GHR ≥19.805 ( OR=4.768, 95% CI:3.131-7.262, P<0.05) was an independent risk factor for CHD. After gradually adjustment for risk factors such as smoking, hypertensive, fasting plasma glucose, age ≥60 years and NLR ≥2.687, GHR ≥19.805 was still an independent risk factor for coronary heart disease(OR and 95% CI were 4.620 (3.049-7.000), 4.768 (3.131-7.262), 6.567 (4.408-9.810), 4.768 (3.131-7.262), 4.768 (3.131-7.262), respectively; all P<0.001). Spearman correlation analysis showed that GHR and NLR were positively correlated with Gensini score ( r=0.312, 0.394; all P<0.05). Conclusion:GHR and NLR were positively correlated with the severity of coronary artery disease, which is of significance in the diagnosis of coronary heart disease. NLR ≥2.687 and GHR ≥19.805 were independent risk factors for CHD. GHR was superior to GGT and HDL-C alone in the diagnosis of CHD,and has certain clinical application value

ABSTRACT

OBJECTIVE To explore the curative effect and mechanism of Yiqi Huoxue decoction in the treatment of coronary heart disease with Qi deficiency and blood stasis syndrome. METHODS The patients with coronary heart dis?ease of Qi deficiency and blood stasis syndrome were treated with Yiqi Huoxue decoction for 3 months, and the changes of cardiac function were observed. 61 serum samples (including 29 cases of disease group and 32 cases of Yiqi Huoxue expression group) were analyzed by non labeled proteomics. The disease group was used as the control group, and the protein with expression level difference of more than 1.2 folds (P<0.05) was screened. The molecular function, biologi?cal pathway and protein interaction of the different proteins were analyzed by bioinformatics, so as to identify the molecu?lar and biological pathway of Yiqi Huoxue decoction in the treatment of coronary heart disease with Qi deficiency and blood stasis syndrome. RESULTS Clinical treatment found that Yiqi Huoxue decoction can improve TCM syndrome score and left ventricular ejection fraction, regulate blood glucose and blood lipid levels, prolong thrombin time, and improve heart function. The results of proteomic quantitative analysis showed that there were 69 proteins with different expression levels in the disease group. Bioinformatics analysis results showed that Yiqi Huoxue decoction may regulate ApoA1, alpha-2 and other proteins to act on HDL assembly, platelet degradation, PI3K Akt signaling pathway, and then play a therapeutic role in coronary heart disease with Qi deficiency and blood stasis syndrome. CONCLUSION Yiqi Huoxue decoction can effectively improved the heart function decline caused by Qi deficiency and blood stasis syn?drome of coronary heart disease. It mainly act on energy metabolism and platelet activation pathway by activating HDL assembly and platelet degradation signal pathway proteins. This study can provide reference for the follow-up treatment mechanism of Qi deficiency and blood stasis syndrome of coronary heart disease.

ABSTRACT

Objective:To evaluate the diagnostic value of circulating microRNA-1 (miR-1) in early coronary artery plaque rupture in patients with stable coronary artery disease (SCAD).Methods:A prospective cohort study was conducted. Sixty-seven patients with SCAD admitted to the department of cardiology of the Third Affiliated Hospital of Soochow University from January to June in 2019 were enrolled. All patients had completed coronary angiography (CAG), percutaneous coronary intervention (PCI) single stent implantation or only CAG was performed according to the CAG results. Blood samples were collected before (0 hour) and 3 hours after the procedure. The expression of plasma miR-1 was detected by real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR), and electrocardiogram was used to detect cardiac troponin I (cTnI) levels. The difference of miR-1 and cTnI levels in PCI or CAG patients before and after procedure were compared, and the value for early diagnosis of coronary artery plaque rupture in SCAD patients was evaluated. The diagnostic efficacy was evaluated by the receiver operating characteristic curve (ROC curve).Results:There were 38 CAG patients and 29 PCI patients. There were no significant differences in gender, age, previous history (without hypertension history) and baseline data of cardiac function between the two groups. The expression of miR-1 after PCI was significantly higher than that before PCI [2 -ΔΔCt: 2.11 (1.56, 2.73) vs. 1.26 (1.07, 1.92), P < 0.01], and there was no significant difference in cTnI level before and after PCI [μg/L: 0.00 (0.00, 0.02) vs. 0.00 (0.00, 0.02), P > 0.05]. There were no significant differences in miR-1 and cTnI levels before and after procedure in the CAG group [miR-1 (2 -ΔΔCt): 1.09 (1.00, 1.40) vs. 1.21 (1.00, 1.71), cTnI (μg/L): 0.00 (0.00, 0.02) vs. 0.00 (0.00, 0.02), both P > 0.05]. ROC curve analysis showed that the area under ROC curve (AUC) and 95% confidence interval (95% CI) of miR-1 in the diagnosis of coronary plaque rupture were 0.794 (0.687-0.900), P < 0.01, the sensitivity was 82.8%, the specificity was 68.4%, and the optimal cut-off value was 1.51. The AUC and 95% CI of the difference of miR-1 before and after operation (ΔmiR-1) were 0.704 (0.567-0.842), P = 0.004, the sensitivity was 62.1%, the specificity was 84.2%, and the optimal cut-off value was 0.39. The efficancy of miR-1 and ΔmiR-1 after procedure to diagnose coronary plaque rupture in patients with SCAD was similar ( Z = 1.287, P = 0.198). However, baseline miR-1 might not predict whether patients with SCAD need PCI or not (AUC = 0.630, P > 0.05). Multivariate binary Logistic regression analysis showed that increased postoperative miR-1 expression was an independent risk factor for coronary plaque rupture in SCAD patients [odds ratios ( OR) = 2.887, 95% CI was 1.044-7.978, P = 0.041]. Conclusion:Circulating miR-1 might have the value for early diagnosis of coronary artery plaque rupture in SCAD patients.

ABSTRACT

Objective:To explore the early warning and prediction value of GDF15 for sudden death patients.Methods:From January to December 2018, 49 patients with sudden death who were treated in the Emergency Department of the First Clinical Center of PLA General Hospital were included in the case group, and 46 healthy physical examiners in the Physical Examination Center of the Hospital were randomly selected as the control group. The general situation, comparison of myocardial markers and analysis of the basic data of the case group were carried out, so as to evaluate the early warning value of each myocardial marker in sudden death.Results:Patients aged 40-49 years old accounted the highest proportion among sudden death cases, reaching 26.54%. Sudden death under 60 years old accounted for 59.19%, and the ratio of male to female was 3.83:1. There were significant differences between the case group and the control group in CK-MB [(41.35±98.38) vs. (3.13±2.17), P=0.009], CK [(2652.82±6845.66) vs. (102.73±47.93), P=0.012], and GDF15 [(549.80±809.79) vs. (115.70±167.42), P=0.001]. At the same time, the AUC value of GDF15 was 0.816, which has the highest diagnostic value for sudden death. And CK-MB, CK and GDF15 had no correlation with age. Conclusions:GDF15, as a biological marker, has a good early warning function in sudden death.

ABSTRACT

Objective:To systematically sort out and summarize the medication rules of clinical prescriptions for coronary heart disease with heart failure of Qi deficiency and blood stasis syndrome,and to provide reference for selecting prescriptions and medications for the treatment of coronary heart disease (CHD) with traditional Chinese medicine (TCM). Method:All relevant literature concerning the treatment of CHD with compound TCM prescriptions for Qi deficiency and blood statis syndrome from 2000 to 2020 were retrieved from the China National Knowledge Network (CNKI),WanFang database (WanFang),and VIP journal database (VIP),and the names of prescriptions and drug components were extracted,followed by the frequency of drug use and drug category. Association rules of high-frequency drugs were analyzed by SPSS 18.0,and systematic clustering analysis was conducted by SPSS 21.0. Result:Finally,41 qualified literature articles covering 35 prescriptons and 66 drugs were included in the study. The total frequency of the drugs was 433 times. Among them,there were a total of 25 traditional Chinese medicines with a frequency of ≥5 times. The top 3 frequently used Chinese medicines were Astragali Radix (8.8%),Salviae Miltiorrhizae Radix et Rhizoma (7.2%),Chuanxiong Rhizoma (5.8%). A total of 15 types of drugs were involved,among which tonic drugs (31.4%),blood promoting and blood stasis drugs (28.2%),and hydration and dampening drugs (7.6%) were used most frequently. The association rule analysis of traditional Chinese medicines with frequency of ≥ 5 showed that there were 13 pairs of binomial associations in 25 traditional Chinese medicines,with Astragali Radix in combination with Salviae Miltiorrhizae Radix et Rhizoma,Chuanxiong Rhizoma,Carthami Flos,et al. There were 8 groups of three associations,with Astragali Radix,Salviae Miltiorrhizae Radix et Rhizoma,and Chuanxiong Rhizoma as the main combinations. A systematic clustering analysis showed that the clustering effect was best when the 25 traditional Chinese medicines were clustered into 5 categories. Conclusion:The treatment of coronary heart disease with heart failure of Qi deficiency and blood stasis syndrome is based on replenishing qi and activating blood circulation,supplemented by warming yang,diuresis,and phlegm-resolving drugs,which can enhance the clinical efficacy. Two basic prescriptions of Buyang Huanwutang and Si junzitang are extracted. Other combinations of prescriptions and drugs can provide references for the clinical treatment of coronary heart disease with heart failure.

ABSTRACT

Cardiovascular and cerebrovascular diseases are one of the major diseases endangering human health, and its morbidity and mortality are still in the rising stage in our country. Traditional Chinese medicine (TCM) injections play an important role in the prevention and treatment of cardiovascular and cerebrovascular diseases due to their advantages of rapid onset, remarkable curative effect, and convenient use. Among them, Danhong injection (DHI), a Chinese medicine injection for promoting blood circulation and removing blood stasis, is widely used in the clinical treatment of cardio-cerebrovascular diseases. DHI is composed of Salviae Miltiorrhizae Radix et Rhizoma (Danshen in Chinese) and Carthami Flos (Honghua in Chinese), and mainly contains phenolic acids, tanshinones and flavonoids. A large number of studies have shown that DHI has a significant effect in the treatment of ischemic cardio-cerebrovascular diseases, is a representative drug of co-therapy of brain and heart of TCM, its pharmacological effects related to many aspects such as anti-inflammatory, anti-oxidation, anti-coagulation. At the same time, Other studies have also explained the protective effects of DHI on cardiovascular and cerebrovascular diseases through the overall regulation and intervention of multiple targets and pathways. However, DHI has a wide range of clinical applications, there are still many unknown pharmacological effects to be further explored. Therefore, this article summarizes the current researches on the chemical components of DHI, the multi-target and multi-path pharmacological mechanisms of DHI in the treatment of cardiovascular and cerebrovascular diseases, and introduces the latest pharmacological research progress, so as to provide theoretical guidance for clinical rational drug use and subsequent in-depth research.

ABSTRACT

To systematically evaluate the effect of traditional Chinese medicine(TCM) on the expression of inflammatory factors in peripheral blood of patients with coronary heart disease complicated with anxiety and depression,and explore its efficacy and safety in treatment of anxiety and depression. In this study,CNKI,VIP database,WanFang database,PubMed and Cochrane Library were searched to collect randomized controlled trials(RCTs) of TCM in the treatment of coronary heart disease complicated with anxiety and depression,and 2 researchers independently screened the literatures and extracted the data. The quality of the included literatures was evaluated with Cochrance bias risk evaluation tool and Meta analysis was conducted by Cochrane Revman 5.3 software. A total of 21 research articles were included,with a total sample size of 2 342 cases,1 175 cases in the treatment group and 1 167 cases in the control group. Meta analysis results showed that the treatment group reduced the hypersensitive C-reactive protein(hs-CRP)[standard mean difference(SMD)=-1.61,95% confidence interval(CI)(-2.14,-1.09),P<0.01],interleukin(IL)-8[mean difference(MD)=-5.03,95% CI(-8.37,-1.70),P=0.003],IL-17[MD=-33.27,95% CI(-40.15,-26.39),P<0.01],tumor necrosis factor(TNF)-α[SMD=-1.18,95% CI(-1.98,-0.38),P<0.01],and homocysteine(Hcy)[MD=-3.45,95% CI(-4.85,-2.04),P<0.01]. The treatment group was better than the control group in terms of relieving anxiety and depression,i.e. scores of Hamilton anxiety scale(HAMA) [SMD=-1.97,95% CI(-2.48,-1.46),P<0.01],Hamilton depression scale(HAMD) [SMD=-1.94,95% CI(-2.50,-1.38),P<0.01],and self-rating depression scale(SDS)[SMD=-0.72,95% CI(-0.90,-0.54),P<0.01],so in terms of ,with statistically significant difference. 4 articles mentioned that no obvious adverse reactions occurred,4 articles mentioned that the treatment group had drowsiness,dry mouth and bitter mouth,gastrointestinal reactions,but the incidence rates were significantly lower than those of the control group. The other 13 articles did not mention the occurrence of adverse reactions.

ABSTRACT

Objective:To explore the correlations of the severity of heart failure related to coronary heart disease arising from Qi deficiency and blood stasis with cardiac function indexes, energy metabolism indexes, coagulation function indexes, and inflammatory factors, in order to provide a scientific basis for further research on the biological foundation of this disease. Method:Two hundred patients with heart failure related to coronary heart disease of Qi deficiency and blood stasis syndrome were collected and then classified into mild, moderate and severe groups according to their scores of Qi deficiency and blood stasis syndrome. Meanwhile, 40 healthy persons confirmed by physical examination during the same period were included into the control group. Such biological indexes as cardiac function indexes, energy metabolism indexes, coagulation function indexes, and inflammatory factors were determined in patients of each group for comparison. Then the Spearman rank correlation analysis was conducted to figure out the correlations between differential indexes and the severity of Qi deficiency and blood stasis syndrome, followed by the determination of risk factors for the severity of Qi deficiency and blood stasis syndrome by ordered logistic regression analysis. Result:The cardiac function indexes, energy metabolism indexes, coagulation function indexes, and inflammatory factors in patients with heart failure related to coronary heart disease arising from Qi deficiency and blood stasis varied significantly. There were significant statistical differences in the levels of N-terminal pro-B-type natriuretic peptide (NT-ProBNP), 6-minute walk test (6MWT), heart-type fatty acid-binging protein (H-FABP), prothrombin time (PT), activated partial thromboplastin time (APTT), tumor necrosis factor-<italic>α</italic> (TNF-<italic>α</italic>), and nitric oxide (NO) among the mild, moderate, and severe groups (<italic>P</italic><0.05). The severity of Qi deficiency and blood stasis syndrome was positively correlated with NT-ProBNP (<italic>r</italic>=0.144), PT (<italic>r</italic>=0.173), and APTT (<italic>r</italic>=0.144), but negatively with 6MWT (<italic>r</italic>=-0.287). The 6MWT[odds ratio(OR)=0.995, 95% confidence interval(CI) 0.991-0.998),<italic>P</italic><0.01] and APTT(OR=1.088,95%CI 1.021-1.157,<italic>P</italic><0.01) were independent risk factors affecting the severity of heart failure related to coronary heart disease arising from Qi deficiency and blood stasis. Conclusion:The severity of heart failure related to coronary heart disease of Qi deficiency and blood stasis syndrome is closely related to NT-ProBNP, 6MWT, H-FABP, PT, APTT, TNF-<italic>α</italic>, and NO. Moreover, 6MWT and APTT can be used as independent risk factors to evaluate the severity of patients with heart failure related to coronary heart disease due to Qi deficiency and blood stasis.

ABSTRACT

Objective:To explore the mechanism of energy changes in the three stages of the formation of coronary heart disease due to blood stasis in rat model from the perspective of mitochondrial fusion-fission dynamic changes. Method:Thirty healthy male rats were divided into the blank control group (<italic>n</italic>=6) and model group (<italic>n</italic>=24) using SPSS 21.0 simple random sampling method. The rats in the blank control group were fed an ordinary diet, while those in the model group a high-fat diet. After seven days of adaptive feeding, the rats were treated with intragastric administration of vitamin D<sub>3</sub> (VitD<sub>3</sub>) at 300 000 U·kg<sup>-1</sup> and then at 200 000 U·kg<sup>-1</sup> 14 d later. The high-fat diet continued for 21 d, and six rats were randomly selected as samples for the pre-stage blood stasis syndrome group, followed by model verification and sampling. The remaining rats continued to receive the high-fat diet for 30 d, and six were randomly selected and categorized into the sub-stage blood stasis syndrome group, followed by model verification and sampling. The rest of rats were classified into the heart blood stasis syndrome group. While continuing the high-fat diet, they were also treated with multipoint subcutaneous injection of isoproterenol (ISO,5 mg·kg<sup>-1</sup>) for three consecutive days. One week later, the electrocardiogram (ECG) was recorded for determining whether the modeling was successful and the samples were taken at the same time. The changes in mitochondrial morphology and quantity were observed under a transmission electron microscope. The expression of mitochondrial dynamics-related proteins was measured by Western blot and the cellular localization of related proteins by immunofluorescence assay. Result:The levels of total cholesterol and low-density lipoprotein cholesterol in the pre-stage and sub-stage blood stasis syndrome groups were significantly increased as compared with those in the blank control group (<italic>P</italic><0.05). The blood rheology index in the pre-stage blood stasis syndrome group was significantly elevated in contrast to that in the blank control group (<italic>P</italic><0.05). The three-layered membrane of the aorta in the blank group was intact. However, the tunica media of the pre-stage blood stasis syndrome group began to show obvious calcification, with a small number of inflammatory cells adhering to the intima. The subintima and media smooth muscles in the sub-stage blood stasis syndrome group exhibited cavity structures. The three-layered structure of the arterial wall in the heart blood stasis syndrome group was severely damaged. The ECG of the blank control group revealed the regular appearance of P wave,regular QRS waveform (no broadening or deformity), and no obvious ST-segment depression or elevation. The ECG of the pre-stage blood stasis syndrome group showed no obvious abnormalities as compared with that of the blank control group. In the sub-stage blood stasis syndrome group, the ECG showed an upward trend of the J point and slight ST-segment elevation, with the elevation≤0.1 mV. The ECG in the heart blood stasis syndrome group displayed significant ST-segment depression (>0.1 mV) and J point depression >0.1 mV. The mitochondria in the blank control group were normal in size and morphology, with clear and dense cristae, whereas those in the pre-stage blood stasis syndrome group were fusiform with sparse cristae. Some mitochondria in the sub-stage blood stasis syndrome group were significantly elongated, and even vacuole-like changes were present. In the heart blood stasis syndrome group, the mitochondria were ruptured. As demonstrated by comparison with the blank control group, the expression levels of mitofusin 2 (Mfn2), dynamin-related protein 1 (Drp1), and fission protein 1 (Fis1) in the model group were significantly up-regulated (<italic>P</italic><0.05,<italic>P</italic><0.01). Compared with the pre-stage blood stasis syndrome group, the heart blood stasis syndrome group exhibited down-regulated Mfn2 (<italic>P<</italic>0.05). Compared with the blank control group and the pre-stage blood stasis syndrome group, the sub-stage blood stasis syndrome group and the heart blood stasis syndrome group displayed down-regulated optic atrophy 1(OPA1) (<italic>P</italic><0.05,<italic>P</italic><0.01). The Drp1 and Fis1 protein expression declined significantly in the sub-stage blood stasis syndrome group in comparison with that in the pre-stage blood stasis syndrome group (<italic>P</italic><0.05,<italic>P</italic><0.01). The expression levels of Mfn2 and Drp1 in the heart blood stasis syndrome group were lower than those in the sub-stage blood stasis syndrome group (<italic>P<</italic>0.01). The comparison with the blank control group showed that Mfn2 and OPA1 were extensively accumulated in mitochondria of both the pre-stage and sub-stage blood stasis syndrome groups, while the red-stained Mfn2 was significantly reduced in the heart blood stasis syndrome group. The Drp1/Fis1 fluorescence was weak in the blank group and the pre-stage blood stasis syndrome group but strong in the sub-stage blood stasis syndrome group and heart blood stasis syndrome group. Conclusion:The cardiomyocyte mitochondria dynamics changes with the change in energy demand of cardiomyocytes. Mfn2 is dominated by fusion effect in the early stage of the formation of coronary heart disease due to blood stasis. With the gradual development of this disease, Mfn2 begins to mediate mitochondrial autophagy. OPA1 plays a role in intimal fusion and cristae integrity. The decreased OPA1 expression is closely related to the accelerated progression of coronary heart disease differentiated into blood stasis syndrome. The process by which Drp1 and Fis1 separate damaged mitochondria to prepare for mitochondrial autophagy contributes to alleviating the imbalance between the energy demand and supply of human body.

ABSTRACT

OBJECTIVE@#To investigate the correlation of platelet and coagulation function with blood stasis syndrome (BSS) in coronary heart disease (CHD).@*METHODS@#The protocol for this meta-analysis was registered on PROSPERO (CRD42019129452). PubMed, Excerpta Medica Database (Embase), the Cochrane Library, and China National Knowledge Infrastructure (CNKI) were searched from inception to 1st June, 2020. Trials were considered eligible if they enrolled BSS and non-BSS (NBSS) patients with CHD and provided information on platelet and coagulation function. The platelet function, coagulation function, and fibrinolytic activity were compared between the BSS and NBSS groups. Forest plots were generated to show the SMDs or ESs with corresponding 95% CIs for each study. Subgroup analysis and sensitivity analysis were performed to explore potential sources of heterogeneity.@*RESULTS@#The systematic search identified 1,583 articles. Thirty trials involving 10,323 patients were included in the meta-analysis. The results showed that mean platelet volume, platelet distribution width, platelet aggregation rate, platelet P selectin, fibrinogen, plasminogen activator inhibitor-1 (PAI-1), thromboxane B2 (TXB2), 6-keto-prostaglandin F1alpha (6-keto-PGF1 α), and TXB2/6-keto-PGF1 α were higher in the BSS group than in the NBSS group (P<0.05 or P<0.01). Activated partial thromboplastin time was lower in the BSS group than in the NBSS group in the acute phase of CHD (P<0.01). The R and K values in thromboelastography and tissue plasminogen activator (t-PA) and t-PA/PAI-1 were lower in the BSS group than in the NBSS group (all P<0.01). No difference was found in the results of platelet count, plateletcrit, maximum amplitude, von Willebrand factor, prothrombin time, thrombin time, international normalized ratio, etc. between groups.@*CONCLUSIONS@#Increased platelet function, hypercoagulability, and decreased fibrinolytic activity were found among CHD patients with BSS.

ABSTRACT

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.

ABSTRACT

@#BACKGROUND: The predictive scoring systems for early stent thrombosis (EST) remains blank in China. The study aims to evaluate the risk factors and conduct a prediction model of EST in the Chinese population. METHODS: EST was defined as thrombosis that occurs within the first 30 days after primary percutaneous coronary intervention (PCI). Patients from ten Chinese hospitals diagnosed as stent thrombosis (ST) from January 2010 to December 2016 were retrospectively included as the study group. A control group (1 case:2 controls) was created by including patients without ST, major adverse cardiovascular events, or cerebrovascular events during follow-up. The present study evaluated 426 patients with single-vessel lesions and ultimately included 40 patients with EST and 80 control patients, who were included to identify factors that predicted EST and to develop a prediction scoring system. The other 171 patients without integrated 1:2 pair were used for external validation. RESULTS: EST was independently associated with a low hemoglobin concentration (adjusted odds ratio [OR] 0.946, 95% confidence interval [95% CI] 0.901-0.993, P=0.026), a high pre-PCI Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score (OR 1.166, 95% CI 1.049-1.297, P=0.004), and a DAPT (DAPT) duration of <30 days (OR 28.033, 95% CI 5.302-272.834, P<0.001). The simple EST prediction score provided an area under the curve (AUC) of 0.854 (95% CI 0.777-0.932, P<0.001) with 70.0% sensitivity and 90.0% specificity, and 0.742 (95% CI 0.649-0.835, P<0.001) with 54.5% sensitivity and 81.0% specificity for external validation dataset. CONCLUSIONS: EST may be independently associated with DAPT discontinuation within 30 days, a low hemoglobin concentration, and a high SYNTAX score. The scoring system also has a good ability to predict the risk of EST and may be useful in the clinical setting.

ABSTRACT

BACKGROUND: Studies have shown that serum homocysteine concentration is an independent predictor of the prevalence and severity of coronary artery disease for patients with normal hypersensitivity C-reactive protein levels. OBJECTIVE: To investigate the protective effect of Wenban Decoction on the apoptosis of rat cardiac microvascular endothelial cells (CMECs) induced by homocysteine by regulating PI3K/Akt signaling pathway. METHODS: Rat CMECs were primarily cultured in vitro, and the cells were randomly divided into control group, model group and Wenban Decoction group (50 mg/L Wenban Decoction). The cells in the latter two groups were injured by 10 mmol/L homocysteine prior to the treatment. Cell counting kit-8 was used to detect the cell viability of each group. ELISA was used to determine serum lactate dehydrogenase, malondialdehyde, whole blood catalase, superoxide dismutase, glutathione peroxidase, interleukin 6, intercellular adhesion molecule 1, interleukin 1β, and tumor necrosis factor α. Flow cytometry was used to detect cell apoptosis after addition of LY294002 based on the treatment with Wenban Decoction. Western blot was used to detect the expression of PI3K, Akt, p-Akt, Bax, Bcl-2 and caspase3 protein in the cells. An ethic approval was given by the Animal Experiment Ethics Committee of Liaoning University of Traditional Chinese Medicine (approval No. 21000092018010). RESULTS AND CONCLUSION: Compared with the control group, the survival ability of CMECs in the model group was significantly reduced, the leakage of lactate dehydrogenase was significantly increased, which caused oxidative stress and the release of inflammatory factors, and finally led to a large number of apoptosis. Compared with the model group, Wenban Decoction improved the survival ability of CMECs, reduced the leakage of lactate dehydrogenase, significantly decreased the intracellular levels of interleukin 1β, intercellular adhesion molecule 1, interleukin 6 and tumor necrosis factor α (P < 0.05), as well as reduced the number of apoptotic cells. PI3K inhibitor reversed the inhibitory effect of Wenban Decoction on homocysteine-induced apoptosis of CMECs. To conclude, Wenban Decoction can significantly improve the survival ability of CMECs, reduce the leakage of lactate dehydrogenase, inhibit the level of oxidative stress and the release of inflammatory factors, and ultimately reduce the number of apoptotic cells, which is related to the inhibition of PI3K/Akt signaling pathway.

ABSTRACT

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.

ABSTRACT

Occupational noise is one of the most common occupational hazards in the workplace. Long-term exposure to occupational noise could not only lead to the damage of the hearing system, but also may cause a certain impact on the cardiovascular system. Studies have shown that occupational noise exposure was positively associated with cardiovascular diseases, including hypertension, coronary heart disease and myocardial infarction. However, the results of studies on occupational noise exposure and stroke are still controversial. This paper reviews the relationship between occupational noise exposure and hypertension, coronary heart disease, stroke, myocardial infarction by summarizing the epidemiological data of domestic and foreign population in recent years. Our study could provide evidence for the design and implementation of well-designed epidemiological and mechanism studies, and the recognition of the role of occupational noise exposure in the occurrence and development of cardiovascular diseases, so as to better protect workers' health.

ABSTRACT

Objective To investigate the heart rate control and related influencing factors of patients with coronary heart disease and arrhythmia in Qinghai in 2019. Methods Clinical data of 263 patients with coronary heart disease and arrhythmia in our hospital in 2019 were retrospectively analyzed. According to their resting heart rate control status at 6 months after discharge, the patients were divided into a well-controlled heart rate group (n=151) and a poorly controlled heart rate group (n=112). The clinical characteristics of patients with different heart rate control status were compared, and influencing factors of heart rate control were analyzed. Results Among patients with coronary heart disease and arrhythmia in Qinghai in 2019, atrial arrhythmia had a higher incidence rate (55.51%), and the main types of arrhythmia were atrial premature beat. The rate of good heart rate control of patients at 6 months after discharge was 57.41%. The heart rate control status was related to the resting heart rate at discharge, age, smoking status, treatment methods, type of coronary heart disease, CCS grade, NYHA classification, hypertension, diabetes mellitus, cardiac enlargement, use of beta blocker and awareness of heart rate control target at discharge (t=32.370, P2=26.300, P2=45.690, P2=15.161, P2=67.500, P2=18.788, P2=10.228, P=0.006; χ2=78.769, P2=66.374, P2=51.165, P2=43.360, P2=40.315, P<0.001), and the difference was statistically significant. Smoking, coronary artery bypass grafting, myocardial infarction, diabetes mellitus, non-use of beta blockers, and poor awareness of heart rate control were independent risk factors for poor heart rate control in patients with coronary heart disease and arrhythmia (P<0.05). Conclusion In 2019, the rate of good heart rate control in patients with coronary heart disease and arrhythmia in Qinghai is above the average level, and the health education on heart rate control relate knowledge for high-risk groups should be strengthened.
