The cardiothoracic ratio (CTR) on chest radiography can potentially reflect the lung volume; however, this has not yet been fully established. This study aimed to clarify the relationship between the CTR and the respiratory function in patients with interstitial lung diseases. Methods We reviewed 120 consecutive patients with idiopathic interstitial lung disease who were admitted to our department between April 2018 and March 2023 and who underwent chest radiography, spirometry, and echocardiography. A multiple linear regression analysis was used to identify the factors associated with the CTR. Correlations between the CTR and the respiratory or cardiac function were assessed using Pearson's correlation coefficient. Results A multiple linear regression analysis showed the percent vital capacity (β= -0.598, p<0.001), age (β=0.405, p<0.001), and female sex (β=0.177, p=0.047) to be independently associated with the CTR, whereas no relationship was observed between the left ventricular ejection fraction, body mass index, and smoking habits. The CTR was significantly negatively correlated with the vital capacity (r=-0.490, p<0.001). Conclusion An increased CTR might reflect a decreased vital capacity, but not a decreased cardiac function, in patients with interstitial lung diseases. Measuring the CTR can thus be beneficial for predicting progression in patients with ILD.","PeriodicalId":13719,"journal":{"name":"Internal Medicine","volume":" ","pages":"1025-1030"},"PeriodicalIF":1.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142092839","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, there is a paucity of literature regarding the risk factors for in-hospital death in patients with non-ST-segment elevation myocardial infarction (NSTEMI) and TVD. In this retrospective study, we examined the determinants of in-hospital death in patients with NSTEMI and TVD who underwent percutaneous coronary intervention (PCI) for culprit lesions. Methods The primary objective of this study was to identify the factors associated with in-hospital death using a multivariate analysis. We included 253 patients with NSTEMI and TVD and divided them into a survivor group (n=239) and an in-hospital death group (n=14). Results Systolic blood pressure (SBP) at admission was significantly higher in the survivor group than in the in-hospital death group. The estimated glomerular filtration rate (eGFR) was also higher in the survivor group than in the in-hospital death group. In the multivariate logistic regression analysis, in-hospital death was inversely associated with the SBP at admission [odds ratio (OR) 0.984, 95% confidence interval (CI) 0.970-0.999, p<0.035] and eGFR (OR 0.966, 95% CI 0.939-0.994, p=0.019) and was associated with cardiopulmonary arrest (CPA) before PCI (OR 8.448, 95% CI 1.863-38.309, p=0.006). Conclusion In-hospital death was associated with CPA before PCI and inversely associated with the SBP at admission and eGFR in patients with NSTEMI and TVD who underwent PCI for the culprit lesion. It may be important to recognize these high-risk features in order to improve the clinical outcomes of patients with NSTEMI and TVD.","PeriodicalId":13719,"journal":{"name":"Internal Medicine","volume":" ","pages":"993-999"},"PeriodicalIF":1.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142132654","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}

Methods The Nationwide Gender-specific Atherosclerosis Determinants Estimation and Ischemic Cardiovascular Disease Prospective Cohort study (NADESICO) of 1,187 patients with suspected coronary artery disease 50-74 years old was used to build a MACE prediction model. The ML random forest (RF) model was compared with a logistic regression analysis. The performance of the ML model was evaluated using the area under the curve (AUC) with the 95% confidence interval (CI). Results Among 1,178 patients from the NADESICO dataset, MACEs occurred in 103 (8.7%) patients during a median follow-up of 4.4 years. The AUC of the RF model for MACE prediction was 0.781 (95% CI: 0.670-0.870), which was significantly higher than that of the conventional logistic regression model [AUC, 0.750 (95% CI: 0.651-0.839)]. The important features in the RF model were coronary artery stenosis (CAS) at any site, CAS in the left anterior descending branch, HbA1c level, CAS in the right coronary artery, and sex. In the external validation cohort, the model accuracy of ensemble ML-RF models that were trained on and tuned using the NADESICO dataset was not similar [AUC: 0.635 (95% CI: 0.599-0.672)]. Conclusion The ML-RF model improved the long-term prediction of MACEs compared to the logistic regression model. However, the selected variables in the internal dataset were not highly predictive of the external dataset. Further investigations are required to validate the usefulness of this model.","PeriodicalId":13719,"journal":{"name":"Internal Medicine","volume":" ","pages":"1001-1008"},"PeriodicalIF":1.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142132663","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}
