However, there is limited information available regarding this marker in patients with acute coronary syndrome (ACS). The aim of the study was to explore the association of MDA levels with inhospital mortality among patients with ACS.Materials and methods: The study sample consisted of 556 ACS patients. The leftover plasma samples collected in EDTA vials for troponin T estimation within 24 h of chest pain were used for analysis. Blood samples were collected into tubes for MDA, nitric oxide (NO), inducible nitric oxide synthase (i-NOS), endothelial nitric oxide synthase (e-NOS), total sialic acid (TSA), NT-proBNP, ANP, homocysteine, and cardiac troponin I (cTnI). The blood samples were centrifuged (4000 g , 4 °C) for 10 min, and the obtained serum then kept at -25 °C until the analyses were carried out. The relationship between these markers and inhospital mortality of ACS patients was investigated.Results: Univariate logistic regression analysis revealed significant correlations among sex, age, creatine, MDA, NT-proBNP, ANP, homocysteine, cTnI, NO, e-NOS, i-NOS, and TSA. Further analysis of these variables using the multivariate logistic regression analysis indicated that age, creatine, MDA, and NT-proBNP were independent predictors. Optimal MDA cutoff value of >33.1 predicted inhospital mortality with 85% sensitivity and 88.17% specificity [AUC: 0.905 (95% CI: 0.878-0.928, P < 0.001)].Conclusion: We demonstrated that MDA levels were elevated in cases of inhospital mortality among ACS patients and the optimal MDA cutoff value of >33.1 predicted inhospital mortality with 85% sensitivity and 88.17% specificity.","PeriodicalId":10702,"journal":{"name":"Coronary artery disease","volume":" ","pages":"211-217"},"PeriodicalIF":1.5,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142767086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted a systematic review of the literature on patients with ACS or acute myocardial infarction who reported whether their symptoms were atypical or typical. We determined the proportion of patients with atypical or no chest pain and used meta-analysis to evaluate predictors of atypical presentation and mortality associated with atypical presentation. A total of 43 studies were included with 1 691 401 patients (mean age: 65.4 years, 63.8% male). The proportion of patients with atypical presentation ranged from 4.6 to 74.2% while for those with no chest pain it ranged from 1.4 to 35.5%. Atypical presentation occurred in 11.6% of patients (28 studies) and no chest pain occurred in 33.6% of patients (16 studies). The three strongest factors associated with increased odds of atypical presentation or no chest pain presentation were non-ST-elevation myocardial infarction [odds ratio (OR): 2.38, 95% confidence interval (CI): 1.55-3.64], greater Killip class (OR: 2.22, 95% CI: 1.84-2.67), and prior heart failure (OR: 1.79, 95% CI: 1.76-1.82). There is a two-fold increase in odds of mortality with atypical or no chest pain presentation in ACS compared with the typical presentation (OR: 2.07, 95% CI: 1.71-2.50, I2 = 99%). Atypical presentation occurs in approximately 1 in 10 patients with ACS but can be as high as 1 in 3 in some populations. Patients who present atypically are at two-fold increased risk of mortality.","PeriodicalId":10702,"journal":{"name":"Coronary artery disease","volume":" ","pages":"240-251"},"PeriodicalIF":1.5,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142709134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its diagnostic performance is often limited by low specificity, leading to false-positive results and unnecessary invasive procedures.Objective: This study aims to assess the potential of combining the Selvester QRS score with exercise ECG to enhance diagnostic specificity for OCAD in patients with suspected stable angina.Methods: This retrospective study included 203 patients who presented with chest pain, underwent exercise ECG and were assessed for OCAD by coronary angiography or computed tomography angiography. Receiver operating characteristic analysis identified the optimal Selvester QRS score cutoff and assessed the diagnostic performance of exercise ECG and the combined model. Multivariable logistic regression was performed in the exercise ECG positive and negative groups.Results: Of the 203 patients, 116 were diagnosed with OCAD. The optimal Selvester QRS score cutoff was ≥3, with a sensitivity of 83.6% and a specificity of 93.1%. The combination of a positive exercise ECG and a Selvester QRS score ≥3 achieved the highest specificity (98.9%). Regression analyses showed that Selvester QRS score ≥3 was an independent predictor of OCAD, even in patients with negative exercise ECG results (adjusted odds ratio: 7.018; P < 0.001).Conclusion: The Selvester QRS score can improve the specificity of the exercise ECG in detecting OCAD in patients with suspected stable angina. This approach has the potential to reduce false positives and unnecessary invasive procedures by improving risk stratification.","PeriodicalId":10702,"journal":{"name":"Coronary artery disease","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143771704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
