Multivariate logistic regression indicated that increased Hs-CRP levels were associated with the presence of LRNC (OR = 1.23, 95% CI: 1.07-1.40, p = 0.003) and IPH (OR = 1.26, 95% CI: 1.10-1.45, p = 0.001). Multivariate linear regression confirmed a significant correlation between Hs-CRP level (β = 3.24, 95% CI: 0.66-5.81, p = 0.014) and the IPH volume. For plaque burden, higher Hs-CRP levels were associated with larger max normalized wall index (NWI) (β = 0.01, 95% CI: 0.00-0.02, p = 0.005) and larger Max wall thickness (β = 0.08, 95% CI: 0.02-0.14, p = 0.006). NLR and Hcy levels did not show significant associations with the carotid plaque characteristics.</p><p><strong>Conclusions: </strong>Elevated Hs-CRP levels were found to be closely associated with plaque burden and vulnerable plaque characteristics. The relationship between the elevated Hs-CRP and plaque vulnerability highlights its potential role in risk stratification and early intervention strategies. Further validation in larger, multicenter population studies is required to confirm these associations.</p>","PeriodicalId":45709,"journal":{"name":"Cerebrovascular Diseases Extra","volume":" ","pages":"133-140"},"PeriodicalIF":2.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13241078/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147699899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We examined the independent and combined effects of body mass index (BMI) and waist-to-hip ratio (WHR) on early stroke outcomes across subtypes.</p><p><strong>Methods: </strong>In this prospective cohort study, 714 patients with acute ischemic stroke or transient ischemic attack were enrolled over 6 months. BMI and WHR were assessed on admission. Stroke severity (NIHSS) and functional outcome at discharge (modified Rankin Scale, mRS) were recorded. Stroke etiology was classified using TOAST and ESUS criteria. Multivariable regression and restricted cubic spline models were applied.</p><p><strong>Results: </strong>A U-shaped association emerged between BMI and both stroke severity and recovery, with overweight patients (BMI 25.0-29.9 kg/m2) showing the lowest NIHSS and highest independence rate (mRS 0-2: 65%). Underweight and obese patients had significantly worse outcomes (p < 0.001). WHR was an independent predictor of higher stroke severity (β = +2.8; 95% CI: 2.1-3.5) and poor outcome (OR = 0.70; 95% CI: 0.52-0.94) and added prognostic value when combined with BMI. A sex-specific interaction indicated greater benefit from overweight in women (OR = 1.72; p = 0.02). Subtype analysis revealed a U-shaped BMI association in cardioembolic stroke (p = 0.014) but not in ESUS.</p><p><strong>Conclusions: </strong>BMI and WHR show distinct, nonlinear, and sex- and subtype-specific associations with stroke severity and functional outcome. WHR was a stronger, BMI-independent predictor of prognosis, particularly in non-cardioembolic stroke. These findings challenge the \"obesity paradox\" and support incorporating adiposity phenotypes into individualized stroke risk models.</p>","PeriodicalId":45709,"journal":{"name":"Cerebrovascular Diseases Extra","volume":" ","pages":"27-44"},"PeriodicalIF":2.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12872198/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145649637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
