We aimed to compare IA and IV contrast use for organ-specific CT abdominal imaging. Five anesthetized swine had external jugular and brachial artery access with ascending aortic pigtail placement. An IV protocol was 100 mL at 5 mL/sec over 20 sec vs 50 mL of IA contrast at 5 mL/sec over 10 sec. Region-of-interest markers were applied to anatomical regions to measure attenuation (HU) over time. IA and IV contrast protocols achieved adequate aortic opacification (IA, 455 ± 289 vs IV, 450 ± 114 HU). The IA contrast aortic attenuation curve reached peak attenuation compared with IV contrast (IA, 8 vs 23 sec; P < .001). Time to peak attenuation was similar between IA and IV contrast in the portal vein (IA, 38 vs IV, 42 sec, P = .25). IA administration achieved a superior contrast-to-noise ratio (CNR) in less time compared with IV (R2 = .94; P < .001). IA contrast achieved adequate opacification with less bolus broadening and a superior CNR compared with IV contrast while using a smaller contrast volume for directed organ-directed imaging.","PeriodicalId":8264,"journal":{"name":"Angiology","volume":" ","pages":"833-840"},"PeriodicalIF":2.2,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10733095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We reported standardized mean difference (SMD) with a 95% confidence interval (CI). Due to high heterogeneity, a random-effects model was used, and the Newcastle-Ottawa scale was used for quality assessment. Thirty-one articles were included in the analysis. Patients in the CIN group had elevated levels of NLR compared with those in the non-CIN group (SMD = 0.78, 95% CI = 0.52-1.04, P < .001). Similar results were observed in either prospective (SMD = 1.03, 95% CI = 0.13-1.93, P = .02) or retrospective studies (SMD = 0.70, 95% CI = 0.45-0.96, P < .001). The pooled sensitivity of NLR was 74.02% (95% CI = 66.54%-81.02%), and the pooled specificity was 60.58% (95% CI = 53.94%-66.84%). NLR shows potential as a cost-effective biomarker for predicting CIN associated with contrast-involved treatments. This could help implement timely interventions to mitigate CIN and improve outcomes.","PeriodicalId":8264,"journal":{"name":"Angiology","volume":" ","pages":"819-832"},"PeriodicalIF":2.2,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140130601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Higher SUA (5.60 vs 4.60 mg/dL, P < .001) and CAR (2.79 vs 2.15, P = .004) were significantly associated with CIN. Multivariate analysis confirmed SUA (Odds Ratio [OR]: 1.577, P < .001) and contrast volume (OR: 1.014, P < .001) as independent predictors. Receiver Operating Characteristic (ROC) analysis identified optimal SUA cutoff at 4.9 mg/dL (sensitivity 67.7%, specificity 68.1%). The predictive value of SUA was stronger among diabetic patients. Additionally, SUA positively correlated with CAR (r = .41, P < .001). A simplified risk score incorporating SUA, CAR, contrast volume, diabetes, and age effectively stratified CIN risk.

We aimed to investigate whether arterial stiffness can explain part of the association between physical activity and the risk of major adverse cardiovascular events (MACE) and all-cause death in men and women. We followed 2583 individuals from the Malmö Diet and Cancer study (2007-2012) for occurrence of MACE in Swedish nationwide registries (mean follow-up: 9 years). Physical activity was self-assessed using a questionnaire. Arterial stiffness was assessed by carotid-femoral pulse wave velocity (cfPWV), the gold standard. Survival analyses were performed using Cox regression. In all individuals, multivariable adjusted hazard ratios per 1 m/s higher PWV were 1.09 (95% confidence interval: 1.05-1.14) for MACE and 1.06 (1.03-1.09) for death. Explained risk estimates for the association from physical activity through arterial stiffness were 12% (0%-100%) for risk of MACE and 5% (1%-16%) for risk of death; in men, corresponding results were 7% (0.4%-28%) and 7% (0%-51%). For women, physical activity was not associated with risk of MACE or death. In conclusion, arterial stiffness may explain part of the association from physical activity to risk of death and potentially risk of MACE in men.","PeriodicalId":8264,"journal":{"name":"Angiology","volume":" ","pages":"33197251366696"},"PeriodicalIF":2.2,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145129765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients were stratified into 4 groups based on OPS (0-3), with all-cause in-hospital mortality as the primary endpoint. Cox proportional hazards modeling was used to identify independent predictors of mortality, and receiver operating characteristic analysis assessed the prognostic performance of OPS.

A pilot retrospective study of 270 consecutive patients who underwent both SE and CCTA to explore which test is more accurate in patients with CAD. Health records and risk factors, SE, and CCTA outcomes were reviewed. SE outcomes were positive (n = 36) and negative (n = 234); CCTA outcomes were based on CAD severity (absent, mild, moderate, and severe). 219 (81.1%) patients had a positive CCTA, indicating the presence of CAD with mild, moderate, or severe stenosis. Despite a positive CCTA (n = 191), 70.7% had a negative SE. This discrepancy was most prevalent in the moderate CCTA category, where 110 patients had a negative SE but positive CCTA. Additionally, 9 patients demonstrated a positive SE despite no significant CCTA findings, indicating that functional abnormalities could have remained undetected by anatomical imaging. It is suggested that significant CAD detected by CCTA does not necessarily suggest myocardial ischemia, while the presence of myocardial ischemia is not necessarily associated with significant CAD, suggesting other causes (e.g., microvascular angina). A positive CCTA but negative SE findings may suggest the presence of coronary collaterals.","PeriodicalId":8264,"journal":{"name":"Angiology","volume":" ","pages":"33197251376087"},"PeriodicalIF":2.2,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145129848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
