Effects of adjuvant Chinese patent medicine therapy on major adverse cardiovascular events in patients with coronary heart disease angina pectoris:a population-based retrospective cohort study

Objective: This study aimed to explore the effects of Chinese patent medicine(CPM) in reducing the incidence of major adverse cardiovascular events(MACE) in patients with coronary heart disease(CHD) angina pectoris and improving clinical effectiveness and provide evidence for its use as clinical adjuvant therapy.Methods: Twenty-eight thousand five hundred and seventeen patients hospitalized with CHD angina pectoris from 6 hospitals were divided into CPM group(n = 11,374) and non-CPM group(n = 17,143) to evaluate the incidence of MACE, including myocardial infarction, percutaneous coronary intervention, and coronary artery bypass grafting.Results: The incidence of MACE in the CPM group was lower than that in the non-CPM group. CPM therapy was an independent protective factor that reduced the overall risk of MACE [adjusted hazard ratio = 0.40, 95% confidence interval(0.33;0.49)]. Patients in the CPM group who received one, two, or three types of CPM could benefit from adjuvant treatment with CPM, and taking more types of CPM was associated with a lower risk of MACE. In addition, the male population was better than the female population at taking CPM, and middle-aged people aged 55 to 64 were more suited to take CPM based on Western medicine.Conclusions: The use of CPM as adjuvant therapy can decrease the occurrence of MACE in patients with CHD angina pectoris,especially in men and middle-aged people, and the drug treatment plan should be optimized accordingly. However, this conclusion needs further verification by prospective cohort studies in the future.

Performance of HEART and TIMI scores in predicting major adverse cardiovascular events(MACEs)of chest pain patients in the emergency department:A prospective observational study

Objective:To compare the value of HEART and TIMI scores in predicting major adverse cardiovascular events(MACEs)of patients with chest pain in the emergency department at a tertiary care hospital in Ahmedabad,a city in western India.Methods:A prospective study was conducted on chest pain patients from January to December 2019.All adult patients with non-traumatic chest pain presenting to the emergency department were included,and their HEART and TIMI scores were evaluated.The patients were followed up within 4 weeks for monitoring any major adverse cardiac events or death.The receiver-operating characteristics(ROC)curve was used to determine the value of HEART and TIMI scores in predicting MACEs.Besides,the specificity,sensitivity,positive predictive value(PPV),and negative predictive value(NPV)of the two scores were assessed and compared.Results:A total of 350 patients were evaluated[mean age(55.03±16.6)years,56.6%of males].HEART score had the highest predictive value of MACEs with an area under the curve(AUC)of 0.98,followed by the TIMI score with an AUC of 0.92.HEART score had the highest specificity of 98.0%(95%CI:96.4%-99.6%),the sensitivity of 75.0%(95%CI:70.7%-79.3%),and PPV of 97.0%(95%CI:94.1%-99.9%)and NPV of 82.5%(95%CI:74.6%-90.4%)for low-risk patients.TIMI score had a specificity of 95.0%(95%CI:92.4%-97.6%),sensitivity of 75.0%(95%CI:69.4%-80.6%),PPV of 92.3%(95%CI:88.1%-96.5%)and NPV of 82.3%(95%CI:73.8%-90.8%)for low-risk patients.Conclusions:HEART score is an easier and more practical triage instrument to identify chest pain patients with low-risk for MACEs compared to TIMI score.Patients with high HEART scores have a higher risk of MACEs and require early therapeutic intervention and aggressive management.

Predictive Effect of CA125 on Adverse Cardiovascular Events in Patients with Chronic Heart Failure

Objective: To study the expression of CA125 in the serum of patients with CHF and the relationship between CA125 level and the occurrence of adverse cardiovascular events. Methods: The clinical data of 132 patients with CHF admitted to Shizuishan Second People’s Hospital from January 2023 to December 2023 were collected and divided into heart function II group, heart function III group, heart function IV group according to cardiac function. 44 healthy subjects who underwent physical examination during the same period were selected as the control group. The clinical data of CA125, NT-proBNP, echocardiography and other clinical data of the four groups were compared, and the incidence of major adverse cardiovascular events was followed up for 12 months. Results: Compared with the control group, the CA125 level in the CHF group was significantly increased (P Conclusion: Serum CA125 level is related to the cardiac function level in CHF patients and increases with the deterioration of cardiac function. The increase of the index is related to the mortality rate and re-hospitalization rate, suggesting that CA125 can be used as an indicator to reflect the severity of heart failure and prognosis monitoring.

Prediabetes: An overlooked risk factor for major adverse cardiac and cerebrovascular events in atrial fibrillation patients

BACKGROUND Prediabetes is a well-established risk factor for major adverse cardiac and cerebrovascular events(MACCE).However,the relationship between prediabetes and MACCE in atrial fibrillation(AF)patients has not been extensively studied.Therefore,this study aimed to establish a link between prediabetes and MACCE in AF patients.AIM To investigate a link between prediabetes and MACCE in AF patients.METHODS We used the National Inpatient Sample(2019)and relevant ICD-10 CM codes to identify hospitalizations with AF and categorized them into groups with and without prediabetes,excluding diabetics.The primary outcome was MACCE(all-cause inpatient mortality,cardiac arrest including ventricular fibrillation,and stroke)in AF-related hospitalizations.RESULTS Of the 2965875 AF-related hospitalizations for MACCE,47505(1.6%)were among patients with prediabetes.The prediabetes cohort was relatively younger(median 75 vs 78 years),and often consisted of males(56.3%vs 51.4%),blacks(9.8%vs 7.9%),Hispanics(7.3%vs 4.3%),and Asians(4.7%vs 1.6%)than the non-prediabetic cohort(P<0.001).The prediabetes group had significantly higher rates of hypertension,hyperlipidemia,smoking,obesity,drug abuse,prior myocardial infarction,peripheral vascular disease,and hyperthyroidism(all P<0.05).The prediabetes cohort was often discharged routinely(51.1%vs 41.1%),but more frequently required home health care(23.6%vs 21.0%)and had higher costs.After adjusting for baseline characteristics or comorbidities,the prediabetes cohort with AF admissions showed a higher rate and significantly higher odds of MACCE compared to the non-prediabetic cohort[18.6%vs 14.7%,odds ratio(OR)1.34,95%confidence interval 1.26-1.42,P<0.001].On subgroup analyses,males had a stronger association(aOR 1.43)compared to females(aOR 1.22),whereas on the race-wise comparison,Hispanics(aOR 1.43)and Asians(aOR 1.36)had a stronger association with MACCE with prediabetes vs whites(aOR 1.33)and blacks(aOR 1.21).CONCLUSION This population-based study found a significant association between prediabetes and MACCE in AF patients.Therefore,there is a need for further research to actively screen and manage prediabetes in AF to prevent MACCE.

Association between hemoglobin glycation index and 5-year major adverse cardiovascular events:the REACTION cohort study

Background:The hemoglobin glycation index(HGI)was developed to quantify glucose metabolism and individual differences and proved to be a robust measure of individual glycosylated hemoglobin(HbA1c)bias.Here,we aimed to explore the relationship between different HGIs and the risk of 5-year major adverse cardiovascular events(MACEs)by performing a large multicenter cohort study in China.Methods:A total of 9791 subjects from the Risk Evaluation of Cancers in Chinese Diabetic Individuals:a Longitudinal Study(the REACTION study)were divided into five subgroups(Q1-Q5)with the HGI quantiles(≤5th,>5th and≤33.3th,>33.3th and≤66.7th,>66.7th and≤95th,and>95th percentile).A multivariate logistic regression model constructed by the restricted cubic spline method was used to evaluate the relationship between the HGI and the 5-year MACE risk.Subgroup analysis between the HGI and covariates were explored to detect differences among the five subgroups.Results:The total 5-year MACE rate in the nationwide cohort was 6.87%(673/9791).Restricted cubic spline analysis suggested a U-shaped correlation between the HGI values and MACE risk after adjustment for cardiovascular risk factors(x^(2)=29.5,P<0.001).After adjustment for potential confounders,subjects with HGIs≤-0.75 or>0.82 showed odds ratios(ORs)for MACE of 1.471(95%confidence interval[CI],1.027-2.069)and 2.222(95%CI,1.641-3.026)compared to subjects with HGIs of>-0.75 and≤-0.20.In the subgroup with non-coronary heart disease,the risk of MACE was significantly higher in subjects with HGIs≤-0.75(OR,1.540[1.039-2.234];P=0.027)and>0.82(OR,2.022[1.392-2.890];P<0.001)compared to those with HGIs of≤-0.75 or>0.82 after adjustment for potential confounders.Conclusions:We found a U-shaped correlation between the HGI values and the risk of 5-year MACE.Both low and high HGIs were associated with an increased risk of MACE.Therefore,the HGI may predict the 5-year MACE risk.

Association of Remnant-like Particle Cholesterol with Major Adverse Cardiovascular Events in Subjects with Different Levels of Proprotein Convertase Subtilisin/Kexin 9:A 9.5-year Follow-up Study in a Beijing Community Population

Objective::The purpose of this study was to determine the relationship between remnant-like particle cholesterol(RLP-C)and major adverse cardiovascular events(MACEs)in patients with different levels of proprotein convertase subtilisin/kexin 9(PCSK9).Methods::From September 2007 to January 2009,1,859 subjects in Pingguoyuan communities in Beijing were initially screened.After excluding those with bedridden status,mental illness,severe systemic diseases,and missing data,1,680 subjects were recruited for follow up.All recruited subjects were followed up from February 2013 to September 2013(181 subjects were lost to follow-up)and from June 2017 to September 2018(174 subjects were lost to follow up).Finally,1,325 subjects were included in the study.General demographic characteristics,lifestyle and behaviors,disease history and use of medication was collected.Levels of total cholesterol,triglycerides,high-density lipoprotein cholesterol,low-density lipoprotein cholesterol,fast blood glucose,RLP-C,low-density lipoprotein triglycerides and PCSK9 were measured.The levels of RLP-C(low:RLP-C≤157 mg/L;high:RLP-C>157 mg/L)and PCSK9(low:PCSK9≤135.87μg/L;high:PCSK9>135.87μg/L)were represented using quartiles.Subjects were categorized into 4 groups according to their RLP-C and PCSK9 levels:Q4,high levels of RLP-C with high levels of PCSK9;Q3,high levels of RLP-C with low levels of PCSK9;Q2,low levels of RLP-C with high levels of PCSK9;and Q1,low levels of RLP-C with low levels of PCSK9.The association of RLP-C with MACEs in subjects with different PCSK9 levels was evaluated.Results::After a median follow-up of 9.5 years,1,325 subjects were included in the study and a total of 191 MACEs had occurred.The incidence of MACEs was higher in the RLP-C>157 mg/L group than the RLP-C≤157 mg/L group(18.40%vs.10.42%).Cox proportional hazards regression model analysis showed that increased RLP-C levels were associated with an increased risk of MACEs(hazard ratio:1.405;95%confidence interval:1.005-1.964;P<0.005).The incidence of MACEs was higher in the high RLP-C/PCSK9 group vs.the low RLP-C/PCSK9 group(20.68%vs.8.76%).Cox proportional hazards regression model analysis showed that RLP-C was associated with an increased risk of MACEs in subjects with high PCSK9 levels independent of traditional risk factors(hazard ratio:1.791;95%confidence interval:1.168-2.825;P=0.001),but not in those with low PCSK9 levels.Conclusions::RLP-C was identified as a risk factor for MACEs,particularly in subjects with high PCSK9 levels.Lowering PCSK9 levels may reduce residual risk in subjects with elevated plasma RLP-C levels.

The Use of Lipoprotein-Associated Phospholipase A2 in a Chinese Population to Predict Cardiovascular Events

Objective To explore associations between lipoprotein-associated phospholipase A2(Lp-PLA2)and the risk of cardiovascular events in a Chinese population,with a long-term follow-up.Methods A random sample of 2,031 participants(73.6%males,mean age=60.4 years)was derived from the Asymptomatic Polyvascular Abnormalities Community study(APAC)from 2010 to 2011.Serum Lp-PLA2 levels were determined by enzyme-linked immunosorbent assay(ELISA).The composite endpoint was a combination of first-ever stroke,myocardial infarction(MI)or all-cause death.Lp-PLA2 associations with outcomes were assessed using Cox models.Results The median Lp-PLA2 level was 141.0 ng/m L.Over a median follow-up of 9.1 years,we identified 389 events(19.2%),including 137 stroke incidents,43 MIs,and 244 all-cause deaths.Using multivariate Cox regression,when compared with the lowest Lp-PLA2 quartile,the hazard ratios with95%confidence intervals for developing composite endpoints,stroke,major adverse cardiovascular events,and all-cause death were 1.77(1.24–2.54),1.92(1.03–3.60),1.69(1.003–2.84),and 1.94(1.18–3.18)in the highest quartile,respectively.Composite endpoints in 145(28.6%)patients occurred in the highest quartile where Lp-PLA2(159.0 ng/m L)was much lower than the American Association of Clinical Endocrinologists recommended cut-off point,200 ng/m L.Conclusion Higher Lp-PLA2 levels were associated with an increased risk of cardiovascular event/death in a middle-aged Chinese population.The Lp-PLA2 cut-off point may be lower in the Chinese population when predicting cardiovascular events.

Incidence of Major Adverse Cardiovascular and Cerebrovascular Events in Chinese Patients Undergoing Percutaneous Coronary Intervention with Iodixanol: An Observational Postauthorization Study

Objective:This study aimed to evaluate the major adverse cardiovascular and cerebrovascular events(MACCEs)and overall safety profile associated with iodixanol in Chinese patients undergoing percutaneous coronary intervention(PCI).Methods:Patients at 30 centers in China registered in the OpenClinic v3.6 database from October 30,2013,to October 7,2015,were included in the study.The primary endpoint was in-hospital MACCEs including target lesion revascularization(TLR),stroke,stent thrombosis,cardiac death,and PCI-related myocardial infarction(MI)within 72 h post-PCI.Secondary endpoints were MACCEs from 72 h to 30 d post-PCI and other safety events within 30 d post-PCI.Results:A total of 3,042 patients were enrolled.The incidence of MACCEs within 72 h post-PCI was 2.33%(n=71),including cardiac death(0.03%,n=1)and PCI-related MI(2.30%,n=70).The incidence of MACCEs from 72 h to 30 d post-PCI was 0.16%(n=5),including cardiac death(0.10%,n=3),PCI-related MI(0.03%,n=1),and TLR for stent thrombosis(0.03%,n=1).The incidence of composite angiographic or procedural complications was 2.86%(n=87);233(7.86%)patients had results suggesting contrast-induced acute kidney injury.Conclusions:These findings indicate that the use of iodixanol in Chinese patients undergoing PCI is associated with a low incidence of MACCEs,confirming its safety in this population.

Predictive value of bilirubin and serum γ-glutamyltranspeptidase levels in type-2 diabetes mellitus patients with acute coronary syndrome

BACKGROUND Cardiovascular disease is a major complication of diabetes mellitus(DM).Type-2 DM(T2DM)is associated with an increased risk of cardiovascular events and mortality,while serum biomarkers may facilitate the prediction of these outcomes.Early differential diagnosis of T2DM complicated with acute coronary syndrome(ACS)plays an important role in controlling disease progression and improving safety.AIM To investigate the correlation of serum bilirubin andγ-glutamyltranspeptidase(γ-GGT)with major adverse cardiovascular events(MACEs)in T2DM patients with ACS.METHODS The clinical data of inpatients from January 2022 to December 2022 were analyzed retrospectively.According to different conditions,they were divided into the T2DM complicated with ACS group(T2DM+ACS,n=96),simple T2DM group(T2DM,n=85),and simple ACS group(ACS,n=90).The clinical data and laboratory indices were compared among the three groups,and the correlations of serum total bilirubin(TBIL)levels and serumγ-GGT levels with other indices were discussed.T2DM+ACS patients received a 90-day follow-up after discharge and were divided into event(n=15)and nonevent(n=81)groups according to the occurrence of MACEs;Univariate and multivariate analyses were further used to screen the independent influencing factors of MACEs in patients.RESULTS The T2DM+ACS group showed higherγ-GGT,total cholesterol,low-density lipoprotein cholesterol(LDL-C)and glycosylated hemoglobin(HbA1c)and lower TBIL and high-density lipoprotein cholesterol levels than the T2DM and ACS groups(P<0.05).Based on univariate analysis,the event and nonevent groups were significantly different in age(t=3.3612,P=0.0011),TBIL level(t=3.0742,P=0.0028),γ-GGT level(t=2.6887,P=0.0085),LDL-C level(t=2.0816,P=0.0401),HbA1c level(t=2.7862,P=0.0065)and left ventricular ejection fraction(LEVF)levels(t=3.2047,P=0.0018).Multivariate logistic regression analysis further identified that TBIL level and LEVF level were protective factor for MACEs,and age andγ-GGT level were risk factors(P<0.05).CONCLUSION Serum TBIL levels are decreased andγ-GGT levels are increased in T2DM+ACS patients,and the two indices are significantly negatively correlated.TBIL andγ-GGT are independent influencing factors for MACEs in such patients.

Prognostic relevance of ventricular arrhythmias in surgical patients with gastrointestinal tumors

BACKGROUND Individuals diagnosed with gastrointestinal tumors are at an increased risk of developing cardiovascular diseases.Among which,ventricular arrhythmia is a prevalent clinical concern.This suggests that ventricular arrhythmias may have predictive value in the prognosis of patients with gastrointestinal tumors.AIM To explore the prognostic value of ventricular arrhythmias in patients with gastrointestinal tumors receiving surgery.METHODS We retrospectively analyzed data from 130 patients undergoing gastrointestinal tumor resection.These patients were evaluated by a 24-h ambulatory electrocardiogram(ECG)at the Sixth Affiliated Hospital of Sun Yat-sen University from January 2018 to June 2020.Additionally,41 general healthy age-matched and sexmatched controls were included.Patients were categorized into survival and non-survival groups.The primary endpoint was all-cause mortality,and secondary endpoints included major adverse cardiovascular events(MACEs).RESULTS Colorectal tumors comprised 90%of cases.Preoperative ambulatory ECG monitoring revealed that among the 130 patients with gastrointestinal tumors,100(76.92%)exhibited varying degrees of premature ventricular contractions(PVCs).Ten patients(7.69%)manifested non-sustained ventricular tachycardia(NSVT).The patients with gastrointestinal tumors exhibited higher PVCs compared to the healthy controls on both conventional ECG[27(21.3)vs 1(2.5),P=0.012]and 24-h ambulatory ECG[14(1.0,405)vs 1(0,6.5),P<0.001].Non-survivors had a higher PVC count than survivors[150.50(7.25,1690.50)vs 9(0,229.25),P=0.020].During the follow-up period,24 patients died and 11 patients experienced MACEs.Univariate analysis linked PVC>35/24 h to all-cause mortality,and NSVT was associated with MACE.However,neither PVC burden nor NSVT independently predicted outcomes according to multivariate analysis.CONCLUSION Patients with gastrointestinal tumors exhibited elevated PVCs.PVCs>35/24 h and NSVT detected by 24-h ambulatory ECG were prognostically significant but were not found to be independent predictors.

Impact of depression on in-hospital outcomes for adults with type 2 myocardial infarction:A United States population-based analysis

BACKGROUND Type 2 myocardial infarction(T2MI)is an ischemic myocardial injury in the context of oxygen supply/demand mismatch in the absence of a primary coronary event.However,though there is a rising prevalence of depression and its potential association with type 1 myocardial infarction(T1MI),data remains nonexistent to evaluate the asso-ciation with T2MI.AIM To identify the prevalence and risk of T2MI in adults with depression and its impact on the in-hospital outcomes.METHODS We queried the National Inpatient Sample(2019)to identify T2MI hospitalizations using Internal Classification of Diseases-10 codes in hospitalized adults(≥18 years).In addition,we compared sociodemographic and comorbidities in the T2MI cohort with vs without comorbid depression.Finally,we used multivariate regression analysis to study the odds of T2MI hospitalizations with vs without depression and in-hospital outcomes(all-cause mortality,cardiogenic shock,cardiac arrest,and stroke),adjusting for confounders.Statistical significance was RESULTS There were 331145 adult T2MI hospitalizations after excluding T1MI(median age:73 years,52.8%male,69.9%white);41405(12.5%)had depression,the remainder;289740 did not have depression.Multivariate analysis revealed lower odds of T2MI in patients with depression vs without[adjusted odds ratio(aOR)=0.88,95%confidence interval(CI):0.86-0.90,P=0.001].There was the equal prevalence of prior MI with any revascularization and a similar prevalence of peripheral vascular disease in the cohorts with depression vs without depression.There is a greater prevalence of stroke in patients with depression(10.1%)vs those without(8.6%).There was a slightly higher prevalence of hyperlipidemia in patients with depression vs without depression(56.5%vs 48.9%),as well as obesity(21.3%vs 17.9%).There was generally equal prevalence of hypertension and type 2 diabetes mellitus in both cohorts.There was no significant difference in elective and non-elective admissions frequency between cohorts.Patients with depression vs without depression also showed a lower risk of all-cause mortality(aOR=0.75,95%CI:0.67-0.83,P=0.001),cardiogenic shock(aOR=0.65,95%CI:0.56-0.76,P=0.001),cardiac arrest(aOR=0.77,95%CI:0.67-0.89,P=0.001)as well as stroke(aOR=0.79,95%CI:0.70-0.89,P=0.001).CONCLUSION This study revealed a significantly lower risk of T2MI in patients with depression compared to patients without depression by decreasing adverse in-hospital outcomes such as all-cause mortality,cardiogenic shock,cardiac arrest,and stroke in patients with depression.

Association of fatigue with short-term prognosis in young and middle-aged patients with coronary heart disease

Background:To investigate the effect of fatigue on the short-term prognosis of young and middle-aged patients with coronary heart disease(CHD).Methods:A cross-sectional,observational survey was distributed at a tertiary hospital in Suzhou,China.Patients were assessed for fatigue and their prognosis was assessed at 3 and 6 months after discharge.General Information Questionnaire,Fatigue Scale and Seattle Angina Questionnaire(SAQ)were used for the survey.The Cox proportional hazard model was used to analyze the impact of fatigue on the occurrence of major adverse cardiac events(MACEs)at 3 and 6 months after discharge.Multiple linear regression models were used to analyze the effect of fatigue on health-related quality of life(HRQoL)at 3 and 6 months after discharge.Results:199 patients were followed up with in the end.43 patients(21.6%)with MACE three months after discharge had a total SAQ score of(399.76±39.61).The overall SAQ score was(425.14±22.66)and 52 patients(26.1%)experienced MACE six months after discharge.Fatigue was identified as a risk factor for MACE 6 months after discharge by the Cox proportional hazard model(HR=2.939,95%CI:0.177~0.655,P=0.001)and as an independent risk factor for quality of life 3 and 6 months after discharge by multiple linear regression(P<0.001).Conclusions:In individuals who are young or middle-aged and have coronary heart disease,fatigue is a risk factor for the short-term prognosis.It is advised that clinical professionals prioritize patient fatigue assessment and improve management of fatigue symptoms.

Association between serum resistin level and cardiovascular events in postmenopausal women with acute coronary syndrome undergoing percutaneous coronary intervention

Background As an adipocytokine, resistin has been proposed as a link between inflammation, metabolic disorder and atherosclerosis. The aim of the study is to evaluate whether serum resistin is associated with acute coronary syndrome （ACS） and major adverse cardiovascular events （MACEs） among postmenopausal women with ACS undergoing percutaneous coronary intervention （PCI）. Methods A total of 106 consecutive postmenopausal women who underwent coronary angiography for evaluation of suspected myocardial ischemia were enrolled. Pre-procedure serum resistin, inflammatory and metabolic biomarkers were measured. All participants were followed for seven years for MACEs, including cardiovascular death, recurrent nonfatal myocardial infarction, and re-PCl. Results Patients with ACS （n=69） had significantly higher resistin levels than those without coronary artery disease （CAD） （n=37） （4.61 （1.79-10.80） ng/ml vs. 2.36 （0.85-4.15） ng/ml, P=0.002）. Correlation analysis revealed positive correlations between resistin levels and inflammatory and metabolic factors （P 〈0.05）. A follow-up of a mean of 83.4 months showed that patients with ACS suffered more MACEs than those without （13.0% vs. 2.7%, P=0.05）. Adjusted for cardiovascular risks, inflammatory and metabolic factors, multiple Logistic regression analysis indicated that an elevated resistin level was an independent predictor of ACS onset （OR=1.139, 95% CI 1.024-1.268, P=0.017） and of MACEs after PCI （OR=1.099, 95% CI 1.015-1.189, P=-0.019）. To clarify the association between resistin levels and MACEs, ACS patients were divided into two subgroups on the basis of resistin levels. Compared with the low resistin subgroup （≤4.35 ng/ml, n=32）, patients in the high resistin subgroup （〉4.35 ng/ml, n=37） were more prone to suffer MACEs （21.6% vs. 3.1%, P=0.015）. Kaplan-Meier analysis showed a significantly lower event-free survival rate in ACS patients with high resistin levels than in the low resistin subgroup （78.4% vs. 96.9%, Log rank 5.594, P=0.018）. Conclusion An elevated serum resistin level is associated with ACS and cardiovascular events and acts as a predictor in progression of ACS in postmenopausal women.

髓过氧化物酶与超敏C反应蛋白在预警急性冠脉综合征中的价值比较（英文）

Background:High-sensitivity C-reactive protein(hs-CRP)is a major factor for predicting acute coronary syndrome(ACS).Myeloperoxidase(MPO)also plays an important role in atherosclerosis initiation and development.In the present work,a detail comparison between MPO and hs-CRP for early warning ACS is discussed.Objective:To compare the values between MPO and hs-CRP for early warning ACS and predicting major adverse cardiovascular events(MACEs)in CHD patients.Methods:MPO,hs-CRP and ACS-related risk factors from 201 ACS and 210 non-ACS patients were tested,and data were analyzed with SPSS software.Major adverse cardiovascular events(MACEs)were investigated during the 4-year period follow-up in 285 coronary heart disease(CHD)patients.Results:The areas under receiver operating characteristic(ROC)curve for diagnosing ACS were 0.888(95%CI 0.843-0.933)for MPO,and 0.862(95%CI 0.815-0.910)for hs-CRP,respectively.Compared to hs-CRP,MPO had more correlations strongly with ACS-related risk factors of TG,HDL-C and LDL-C in ACS patients(p<0.05).Prospective study demonstrated that the incidences of MACEs associated significantly with elevated MPO baseline level(yes vs no,OR 7.383,95%CI 4.095-13.309)and high hs-CRP baseline level(yes vs no,OR 4.186,95%CI 2.469-7.097).Conclusions:MPO as inflammatory marker for early warning ACS has some advantages compared to hsCRP.Elevated baseline MPO and hs-CRP levels are both valuable predictors of MACEs in CHD patients.

Serum uric acid in patients with acute ST-elevation myocardial infarction

BACKGROUND:Few studies investigated serum uric acid levels in patients with acute STelevation myocardial infarction(STEMI).The study was to assess the clinical value of serum uric acid levels in patients with acute ST-elevation myocardial infarction(STEMI).METHODS:Totally 502 consecutive patients with STEMI were retrospectively studied from January 2005 to December 2010.The level of serum lipid,echocardiographic data and in-hospital major adverse cardiovascular events(MACE) in patients with hyperuricemia(n=119) were compared with those in patients without hyperuricemia(n=383).The relationship between the level of serum uric acid and the degree of diseased coronary artery was analyzed.All data were analyzed with SPSS version 17.0 software for Student's t test,the Chi-square test and Pearson's correlation coefficient analysis.RESULTS:Serum uric acid level was positively correlated with serum triglyceride level.Hyperlipidemia was more common in hyperuricemia patients than in non-hyperuricemia patients(43.7%vs.33.7%,P=0.047),and serum triglyceride level was significantly higher in hyperuricemia patients(2.11±1.24 vs.1.78±1.38,P=0.014).But no significant association was observed between serum uric acid level and one or more diseased vessels(P>0.05).Left ventricular end-diastolic diameter(LVEDd) was larger in hyperuricemia patients than in non-hyperuricemia patients(53.52±6.19 vs.52.18±4.89,P=0.041).The higher rate of left systolic dysfunction and diastolic dysfunction was discovered in hyperuricemia patients(36.4%vs.15.1%,P<0.001;68.2%vs.55.8%,P=0.023).Also,hyperuricemia patients were more likely to have in-hospital MACE(P<0.05).CONCLUSIONS:Serum uric acid level is positively correlated with serum triglyceride level,but not with the severity of coronary artery disease.Hyperuricemia patients with STEMI tend to have a higher rate of left systolic dysfunction and diastolic dysfunction and more likely to have more in-hospital MACE.

Effects of bilirubin on perioperative myocardial infarction and its long-term prognosis in patients undergoing percutaneous coronary intervention

BACKGROUND Although bilirubin is known to be an antioxidant,any relationship with coronary heart disease remains controversial.To the best of our knowledge,no previous study has investigated the association between bilirubin and perioperative myocardial infarction(PMI),including its long-term prognosis.AIM To investigate the impact of bilirubin levels on PMI in patients undergoing percutaneous coronary intervention(PCI),and long-term prognosis in post-PMI patients.METHODS Between January 2014 and September 2018,10236 patients undergoing elective PCI were enrolled in the present study.Total bilirubin(TB)and cardiac troponin I(cTnI)levels were measured prior to PCI and cTnI at further time-points,8,16 and 24 h after PCI.Participants were stratified by pre-PCI TB levels and divided into three groups:<10.2;10.2-14.4 and>14.4μmol/L.PMI was defined as producing a post-procedural cTnI level of>5×upper limit of normal(ULN)with normal baseline cTnI.Major adverse cardiovascular events(MACEs)included cardiac death,MI,stroke and revascularization during a maximum 5-year follow-up.RESULTS PMI was detected in 526(15.3%),431(12.7%)and 424(12.5%)of patients with pre-PCI TB levels of<10.2,10.2-14.4 and>14.4μmol/L(P=0.001),respectively.Multivariate logistical analysis indicated that patients with TB 10.2-14.4 and>14.4μmol/L had a lower incidence of PMI[TB 10.2-14.4μmol/L:Odds ratio(OR):0.854;95%confidence interval(CI):0.739-0.987;P=0.032;TB>14.4μmol/L:OR:0.846;95%CI:0.735-0.975;P=0.021]compared with patients with TB<10.2μmol/L.Construction of a Kaplan-Meier curve demonstrated a higher MACE-free survival time for patients with higher TB than for those with lower TB(log-rank P=0.022).After adjustment for cardiovascular risk factors and angiographic characteristics,multivariate Cox analysis showed that a TB level>14.4μmol/L was associated with a reduced risk of MACEs compared with a TB level<10.2μmol/L(hazard ratio 0.667;95%CI:0.485-0.918;P=0.013).CONCLUSION Bilirubin was a protective factor in PMI prediction.For post-PMI patients,elevated bilirubin levels were independently associated with a reduced risk of MACEs during long-term follow-up.

Clinical characteristics,GRACE score,TIMI score and prognosis of patients with type 2 diabetes mellitus complicated with acute coronary syndrome

Objective:To analyze the clinical characteristics of patients with type 2 diabetes mellitus(T2DM)with acute coronary syndrome(ACS),the global registry of acute coronary events(GRACE)score,the thrombolysis in myocardial infarction(TIMI)score and clinical prognosis.Method:The study was a retrospective one-center observational study,continuous inclusion of 600 ACS patients diagnosed by coronary angiography in our hospital from October 2018 to July 2019.Collect general clinical data,laboratory examination results,imaging data and interventional treatment data of all patients.Were divided into:T2DM with ACS group(group DA)and non-T2DM with ACS(group NDA)according to whether or not they were associated with T2DM.According to the GRACE、TIMI score,the two groups were divided into high risk group,middle risk group and low risk group.All patients underwent coronary angiography to calculate the number of vascular lesions and Gensini scores.Design questionnaire,after discharge to 2 groups of patients by telephone or outpatient follow-up average of 10 months,statistics of the occurrence of MACE events.Result:Among the 600 patients included in the study,362 were male(60.3%)and 238 were female(39.7%)with mean age(64.7±10.3)years.The baseline data showed that the G、TG、UA、CR levels were higher in the DA group than in the NDA group;the proportion of men was lower than in the NDA group.The results of coronary angiography showed that the Gensini score of DA group was higher than that of NDA group,and the proportion of single lesion was lower than that of NDA group.The binary Logistic regression analysis suggested that age and CRP were independent risk factors for MACE events in patients with T2DM.GRACE risk stratification showed that the proportion of high risk group in DA group was significantly higher than that in NDA group,and there was no significant difference between low and middle risk group.TIMI risk stratification showed that the proportion of high risk group in DA group was significantly higher than that in NDA group,while the proportion of low and middle risk group was lower than that in NDA group.The ROC curve shows that the area(AUC)below the ROC curve that GRACE、TIMI score predicted the occurrence of MACE events in patients with T2DM and ACS was 0.707 and 0.586.Conclusion:Patients with T2DM and ACS had higher clinical risk stratification than without T2DM.GRACE score compared with the TIMI score had better predictive value for the occurrence of MACE events after discharge of T2DM with ACS patients.

The role of neutrophil-to-lymphocyte ratio in predicting adverse events of chronic heart failure

Background The neutrophil-to-lymphocyte（N/L） ratio has been associated with poor outcomes in patients with cardiovascular diseases. However, limited study investigated the N/L ratio in patients with CHF. Hence we aimed to evaluate the association between the N/L ratio and the future risk of major adverse cardiovascular events（MACE） in patients with CHF. Methods Four hundred and fifty-two chronic heart failure（CHF） patients from May 2014 to May 2017 were enrolled in this study. The patients were categorized on the basis of the N/L ratio into the lower（〈 2.9） and higher（〉 2.90） groups. Cox regression models were used to analyze the association between the N/L ratio and major adverse cardiovascular event（MACE）. The Kaplan-Meier method was used to evaluate the cumulative hazard for the events. Results A total of 452 patients（275 males, 177 females, mean age 52.2 ± 14.52 years） were enrolled in this study, including the 231 patients in low N/L ratio group and 221 high in N/L ratio group. MACE occurred in 52 patients（11.5%）. In univariate and multivariate analyses, the patients in the high N/L ratio group showed a higher risk for MACE（HR = 1.913, 95% CI 1.512 to 2.388, P 〈0.001; HR = 1.411, 95% CI 1.108 to 1.785, P = 0.002, respectively）. Conclusions Our study demonstrates that the N/L ratio measured at the time of hospital admission is associated with an increased risk for subsequent MACE.

Efficacy of acupuncture on cardiovascular complications in patients with diabetes mellitus in Korea:A nationwide retrospective cohort

Objective The main aim of this study is to investigate whether acupuncture could be an effective complementary treatment for reducing the risk of macrovascular complications in diabetic patients currently taking antidiabetic medications using a nationwide population-based database.Methods We conducted a retrospective cohort study to assess the efficacy of acupuncture on cardiovascular complications in diabetic patients using data from patients between 40 and 79 years of age,newly diagnosed with diabetes between 2003 and 2006,found in the National Health Insurance Service-National Sample Cohort(NHIS-NSC)in Korea.From the data,we identified 21,232 diabetic patients who were taking antidiabetic medication between 2003 and 2006.The selected patients were divided into two groups-those who received acupuncture at least three times and those who received no acupuncture(non-acupuncture)in the year following their diagnosis of diabetes.After 1:1 propensity score matching(PSM),each group had 3350 patients,and the observation ceased at the occurrence of a major adverse cardiovascular event(MACE),which was defined as either myocardial infarction,stroke,or death due to cardiovascular cause.Results After PSM,the acupuncture group had a lower incidence of MACE(hazard ratio[HR]:0.87;95%confidence interval[CI]:0.81-0.94;P=0.0003)and all-cause mortality(HR:0.77;95%CI:0.70-0.84;P<0.0001)than the non-acupuncture group;the HRs for stroke-related mortality(HR:0.75;95%CI:0.56-1.00;P=0.0485),ischemic heart disease mortality(HR:0.53;95%CI:0.34-0.84;P=0.006)and circulatory system disease mortality(HR:0.67;95%CI:0.55-0.82;P<0.0001)were lower in the acupuncture group than in the non-acupuncture group in the secondary analysis.Conclusion Our results indicate that diabetic patients receiving acupuncture treatment might have a lower risk of MACE,all-cause mortality and cardiovascular mortality.This population-based retrospective study suggests beneficial effects of acupuncture in preventing macrovascular complications associated with diabetes.These findings call for further prospective cohort or experimental studies on acupuncture treatment for cardiovascular complications of diabetes.

Lp(a) level is associated with long-term adverse outcomes in patients with coronary heart disease

Background Mounting evidence has suggested that high level of Lipoprotein （a） （Lp [a] ） is associated with increased risk of coronary heart disease （CHD）. However, the impact of Lp （a） on long-term adverse outcomes of CHD undergone coronary angiography （CAG） or percutaneous coronary intervention （PCI） has not been fully examined. Methods We enrolled 1684 patients with CHD between October 2009 and December 2013. The patients were divided into two group according to their median plasma Lp （a） levels： Lp （a）〈16.03 mg/dL （n= 842 patients）, and Lp （a） ≥ 16.03 mg/dL （n=842 patients）. Kaplan-Meier curve was carried out examining the survival time between the two groups. The associations of Lp （a） levels and long-term major adverse cardiovascu- lar events （MACEs） were investigated by cox regression analysis. Results Patients with the high Lp（a） did not have an increased risk of in-hospital MACEs （3.0% vs. 1.7%, P=0.075）, but had a higher long-term MACEs than those in the low Lp（a） group （6.3% vs. 3.1%, P=0.005）. With the median follow-up period of 1.94 years, multivariate Cox regression analysis revealed that a higher Lp （a） level was an independent predictor of longterm MACEs （hazard ratio 1.82, 95% confidence interval 1.04 to 3.18, P=0.036）. Conclusion An elevated level of Lp（a） is significantly associated with long-term adverse outcomes in patients with CHD following CAG or PCI.
