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.

Predicting major adverse cardiovascular events after orthotopic liver transplantation using a supervised machine learning model:A cohort study

BACKGROUND Liver transplant(LT)patients have become older and sicker.The rate of post-LT major adverse cardiovascular events(MACE)has increased,and this in turn raises 30-d post-LT mortality.Noninvasive cardiac stress testing loses accuracy when applied to pre-LT cirrhotic patients.AIM To assess the feasibility and accuracy of a machine learning model used to predict post-LT MACE in a regional cohort.METHODS This retrospective cohort study involved 575 LT patients from a Southern Brazilian academic center.We developed a predictive model for post-LT MACE(defined as a composite outcome of stroke,new-onset heart failure,severe arrhythmia,and myocardial infarction)using the extreme gradient boosting(XGBoost)machine learning model.We addressed missing data(below 20%)for relevant variables using the k-nearest neighbor imputation method,calculating the mean from the ten nearest neighbors for each case.The modeling dataset included 83 features,encompassing patient and laboratory data,cirrhosis complications,and pre-LT cardiac assessments.Model performance was assessed using the area under the receiver operating characteristic curve(AUROC).We also employed Shapley additive explanations(SHAP)to interpret feature impacts.The dataset was split into training(75%)and testing(25%)sets.Calibration was evaluated using the Brier score.We followed Transparent Reporting of a Multivariable Prediction Model for Individual Prognosis or Diagnosis guidelines for reporting.Scikit-learn and SHAP in Python 3 were used for all analyses.The supplementary material includes code for model development and a user-friendly online MACE prediction calculator.RESULTS Of the 537 included patients,23(4.46%)developed in-hospital MACE,with a mean age at transplantation of 52.9 years.The majority,66.1%,were male.The XGBoost model achieved an impressive AUROC of 0.89 during the training stage.This model exhibited accuracy,precision,recall,and F1-score values of 0.84,0.85,0.80,and 0.79,respectively.Calibration,as assessed by the Brier score,indicated excellent model calibration with a score of 0.07.Furthermore,SHAP values highlighted the significance of certain variables in predicting postoperative MACE,with negative noninvasive cardiac stress testing,use of nonselective beta-blockers,direct bilirubin levels,blood type O,and dynamic alterations on myocardial perfusion scintigraphy being the most influential factors at the cohort-wide level.These results highlight the predictive capability of our XGBoost model in assessing the risk of post-LT MACE,making it a valuable tool for clinical practice.CONCLUSION Our study successfully assessed the feasibility and accuracy of the XGBoost machine learning model in predicting post-LT MACE,using both cardiovascular and hepatic variables.The model demonstrated impressive performance,aligning with literature findings,and exhibited excellent calibration.Notably,our cautious approach to prevent overfitting and data leakage suggests the stability of results when applied to prospective data,reinforcing the model’s value as a reliable tool for predicting post-LT MACE in clinical practice.

Performance of the EDACS-ADP incorporating high-sensitivity troponin assay:Do components of major adverse cardiac events matter?

BACKGROUND:The accelerated diagnostic protocol(ADP)using the Emergency Department Assessment of Chest pain Score(EDACS-ADP),a tool to identify patients at low risk of a major adverse cardiac event(MACE)among patients presenting with chest pain to the emergency department,was developed using a contemporary troponin assay.This study was performed to validate and compare the performance of the EDACS-ADP incorporating high-sensitivity cardiac troponin I between patients who had a 30-day MACE with and without unstable angina(MACE I and II,respectively).METHODS:A single-center prospective observational study of adult patients presenting with chest pain suggestive of acute coronary syndrome was performed.The performance of EDACS-ADP in predicting MACE was assessed by calculating the sensitivity and negative predictive value.RESULTS:Of the 1,304 patients prospectively enrolled,399(30.6%;95%confidence interval[95%CI]:27.7%–33.8%)were considered low-risk using the EDACS-ADP.Among them,the rates of MACE I and II were 1.3%(5/399)and 1.0%(4/399),respectively.The EDACS-ADP showed sensitivities and negative predictive values of 98.8%(95%CI:97.2%–99.6%)and 98.7%(95%CI:97.0%–99.5%)for MACE I and 98.7%(95%CI:96.8%–99.7%)and 99.0%(95%CI:97.4%–99.6%)for MACE II,respectively.CONCLUSION:EDACS-ADP could help identify patients as safe for early discharge.However,when unstable angina was added to the outcome,the 30-day MACE rate among the designated lowrisk patients remained above the level acceptable for early discharge without further evaluation.

Contemporary nationwide trends in major adverse cardiovascular events in young cannabis users without concomitant tobacco,alcohol,cocaine use

BACKGROUND Cannabis use has increased among young individuals in recent years.Although dependent cannabis use disorder(CUD)has been associated with various cardiac events,its effects on young adults without concurrent substance use remain understudied.AIM To examine trends in hospitalizations for major adverse cardiac and cerebrovascular events(MACCE)in this cohort.METHODSWe used the National Inpatient Sample(2016-2019)to identify hospitalized young individuals(18-44 years),excluding those with concurrent substance usage(tobacco,alcohol,and cocaine).They were divided into CUD+and CUD-.Using International Classification of Diseases-10 codes,we examined the trends in MACCE hospitalizations,including all-cause mortality(ACM),acute myocardial infarction(AMI),cardiac arrest(CA),and acuteischemic stroke(AIS).RESULTSOf 27.4 million hospitalizations among young adults without concurrent substance abuse,4.2%(1.1 million)hadco-existent CUD.In CUD+group,hospitalization rates for MACCE(1.71%vs 1.35%),AMI(0.86%vs 0.54%),CA(0.27%vs 0.24%),and AIS(0.49%vs 0.35%)were higher than in CUD-group(P<0.001).However,rate of ACMhospitalizations was lower in CUD+group(0.30%vs 0.44%).From 2016 to 2019,CUD+group experienced arelative rise of 5%in MACCE and 20%in AMI hospitalizations,compared to 22%and 36%increases in CUDgroup(P<0.05).The CUD+group had a 13%relative decrease in ACM hospitalizations,compared to a 10%relative rise in CUD-group(P<0.05).However,when adjusted for confounders,MACCE odds among CUD+cohort remain comparable between 2016 and 2019.CONCLUSIONThe CUD+group had higher rates of MACCE,but the rising trends were more apparent in the CUD-group overtime.Interestingly,the CUD+group had lower ACM rates than the CUD-group.

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.

Clinical perspective on C-reactive protein in prognostication of major adverse cardiac events in the elderly with established coronary heart disease

The systemic response to tissue injury, regardless of cause is characterized by a cytokine-mediated alteration in the hepatic synthesis of a number of different plasma proteins,known collectively as 'acute phase reactants'. These proteins include C-reactive protein, serum amyloid A protein, alphal glycoprotein, ceruloplasmin, alpha macroglobulins, complement components (C1-C4, factor B, C9, C11), alpha1antitrypsin, alpha1 antichymotrypsin, fibrinogen, prothrombin,factor Ⅷ, plasminogen, haptoglobin, ferritin, immunoglobulins and lipoproteins. The initiation of the acute phase response is linked to the production of hormone-like polypeptide mediators now called cytokines, namedly, interleukin 1(IL-1),tumor necrosis factor, interferon gamma, interleukin 6 (IL-6),leukemia inhibitory factor, ciliary neurotropic factor, oncostatin M, and interleukin 11 (IL- 11).……

Critical values of monitoring indexes for perioperative major adverse cardiac events in elderly patients with biliary diseases

BACKGROUND Major adverse cardiac events(MACE) in elderly patients with biliary diseases are the main cause of perioperative accidental death, but no widely recognized quantitative monitoring index of perioperative cardiac function so far.AIM To investigate the critical values of monitoring indexes for perioperative MACE in elderly patients with biliary diseases.METHODS The clinical data of 208 elderly patients with biliary diseases in our hospital from May 2016 to April 2021 were retrospectively analysed. According to whether MACE occurred during the perioperative period, they were divided into the MACE group and the non-MACE group.RESULTS In the MACE compared with the non-MACE group, postoperative complications, mortality, hospital stay, high sensitivity troponin-Ⅰ(Hs-TnI), creatine kinase isoenzyme(CK-MB), myoglobin(MYO), B-type natriuretic peptide(BNP), and Ddimer(D-D) levels were significantly increased(P < 0.05). Multivariate logistic regression showed that postoperative BNP and D-D were independent risk factors for perioperative MACE, and their cut-off values in the receiver operating characteristic(ROC) curve were 382.65 pg/mL and 0.965 mg/L, respectively.CONCLUSION The postoperative BNP and D-D were independent risk factors for perioperative MACE, with the critical values of 382.65 pg/mL and 0.965 mg/L respectively. Consequently, timely monitoring and effective maintenance of perioperative cardiac function stability are of great clinical significance to further improve the perioperative safety of elderly patients with biliary diseases.

Predictive Value of Carotid-femoral Pulse Wave Velocity for Major Adverse Cardiovascular Events and All-cause Mortality in Different Age Groups of a Chinese Community

Objective:To investigate the predictive value of carotid-femoral pulse wave velocity(cf-Pw)for assessing major adverse cardiovascular events(MACE)and all-cause mortality in different age groups of a Chinese community.Methods:This is an observational study which enrolled 1,325 individuals from a community in Beijing from September 2007 to October 2018.They were classified based on age into<65-year-old(n=572)and≥65-year-old(n=753)groups,and on cf-PWV into cf-PWV<12 m/s(n=501)and cf-PWV≥12 m/s(n=824)group.The incidence rates of MACE and all-cause mortality were recorded for both the groups during the follow-up period of 9.5 years.The predictive value of cf-PWV for MACE and all-cause mortality in the 2 age groups was estimated using the Cox proportional hazards regression models.Results:The baseline cf-PWV showed positive correlation with age(r=0.462,P<0.001).During the follow-up period,191 MACE and 84 all-cause mortality cases were recorded in the study population.The incidence rates of MACE(χ^(2)=27.196,P<0.001)and all-cause mortality(χ^(2)=9.473,P=0.002)were significantly higher in subjects with cf-PWV≥12 m/s than in subjects with cf-PWV<12 m/s.Cox proportional hazards regression model analyses demonstrated that cf-PWV was an independent risk factor in the<65-year-old group for MACE(hazard ratio:1.310;95%confidence interval:1.007-1.560;P=0.038)and all-cause mortality(hazard ratio:1.412;95%confidence interval:1.133-1.936;P=0.005)after adjusting for several risk factors.However,both univariate and multivariate analyses demonstrated that cf-PWV was not an independent risk factor for MACE or all-cause mortality in the≥65-year-old group(P>0.05).Conclusion:cf-PWV,a measure of arterial stifness,emerged as an independent risk factor for MACE and all-cause mortality insubjectsbelow65yearsofage.

Anti-inflammatory Therapy Progress in Major Adverse Cardiac Events after PCI:Chinese and Western Medicine

Acute coronary syndrome(ACS)is one of the leading causes of death in cardiovascular disease.Percutaneous coronary intervention(PCI)is an important method for the treatment of coronary heart disease(CHD),and it has greatly reduced the mortality of ACS patients since its application.However,a series of new problems may occur after PCI,such as in-stent restenosis,no-reflow phenomenon,in-stent neoatherosclerosis,late stent thrombosis,myocardial ischemia-reperfusion injury,and malignant ventricular arrhythmias,which result in the occurrence of major adverse cardiac events(MACE)that seriously reduce the postoperative benefit for patients.The inflammatory response is a key mechanism of MACE after PCI.Therefore,examining effective anti-inflammatory therapies after PCI in patients with ACS is a current research focus to reduce the incidence of MACE.The pharmacological mechanism and clinical efficacy of routine Western medicine treatment for the anti-inflammatory treatment of CHD have been verified.Many Chinese medicine(CM)preparations have been widely used in the treatment of CHD.Basic and clinical studies showed that effectiveness of the combination of CM and Western medicine treatments in reducing incidence of MACE after PCI was better than Western medicine treatment alone.The current paper reviewed the potential mechanism of the inflammatory response and occurrence of MACE after PCI in patients with ACS and the research progress of combined Chinese and Western medicine treatments in reducing incidence of MACE.The results provide a theoretical basis for further research and clinical treatment.

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.

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.

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.

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.

Excess cardiovascular mortality in men with non-alcoholic fatty liver disease:A cause for concern!

Non-alcoholic fatty liver disease(NAFLD)has emerged as the commonest cause of chronic liver disease worldwide in recent years.With time,our understanding of NAFLD has evolved from an isolated liver condition to a systemic disease with significant manifestations beyond the liver.Amongst them,cardiovascular diseases(CVDs)are the most important and clinically relevant.Recent research supports a strong independent link between NALFD and CVD beyond the shared risk factors and pathophysiology.Female sex hormones are well known to not only protect against CVD in pre-menopausal females,but also contribute to improved adipose tissue function and preventing its systemic deposition.Recent research highlights the increased risk of major adverse cardiovascular-cerebral events(MACCE)amongst male with NAFLD compared to females.Further,racial variation was observed in MACCE outcomes in NAFLD,with excess mortality in the Native Americans and Asian Pacific Islanders compared to the other races.

Atrial fibrillation and prediabetes:A liaison that merits attention!

Atrial fibrillation(AF)and prediabetes share common pathophysiological mechanisms with endothelial dysfunction and inflammation playing a key role.The resultant vicious cycle which sets in culminates in a higher atherogenicity and thermogenicity of the vascular system resulting in increased major adverse cardiac or cerebrovascular event(MACCE)events.However,the same has not convincingly been verified in real-world settings.In the recent retrospective study by Desai et al amongst AF patients being admitted to hospitals following MACCE,prediabetes emerged as an independent risk factor for MACCE after adjusting for all confounding variables.However,certain questions like the role of metformin,quantifying the risk for MACCE amongst prediabetes compared to diabetes,the positive impact of reversion to normoglycemia remain unanswered.We provide our insights and give future directions for dedicated research in this area to clarify the exact relationship between the two.

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.

Long-term outcomes of titanium-nitride-oxide coated stents and drug-eluting stents in acute coronary syndrome:A systematic review and meta-analysis

BACKGROUND In severe cases of coronary artery disease,percutaneous coronary intervention provide promising results.The stent used could be a drug-eluting stent(DES)or a titanium-nitride-oxide coated stent(TiNOS).AIM To compare the 5-year effectiveness and safety of the two stent types.METHODS The following systematic review and meta-analysis was conducted in accordance with the preferred reporting items for systematic reviews and meta-analysis guidelines,and PubMed/MEDLINE,Scopus,and Cochrane Central were searched from inception till August 2023.Primary outcomes were major adverse cardiac events(MACE),cardiac death,myocardial infarction(MI),cardiac death or MI,and ischemia-driven total lesion revascularization(ID-TLR).RESULTS Four randomized controlled trials(RCT),which analyzed a sum total of 3045 patients with acute coronary syndrome(ACS)after a median follow-up time of 5 years were included.Though statistically insignificant,an increase in the ID-TLR was observed in patients receiving TiNOSs vs DESs.In addition,MI,cardiac death and MI,and definite stent thrombosis(DST)were significantly decreased in the TiNOS arm.Baseline analysis revealed no significant results with meta-regression presenting non-ST elevated MI(NSTEMI)as a statistically significant covariate in the outcome of MACE.CONCLUSION TiNOS was found to be superior to DES in terms of MI,cardiac death or MI,and DST outcomes,however,the effect of the two stent types on ID-TLR and MACE was not significant.A greater number of studies are required to establish an accurate comparison of patient outcomes in TiNOS and DES.
