Background The neutrophil-percentage-to-albumin ratio (NPAR) functions as an integrative marker representing inflammatory response and nutritional health. However, its association with mortality in elderly stroke survivors has not been explored. Methods This cohort study analyzed data from 1,026 the National Health Nutrition Examination Survey (NHANES, 1999-2018). of NPAR was using Cox proportional hazards regression, restricted cubic splines (RCS), Kaplan-Meier survival analysis, time-dependent receiver operating characteristic (ROC) curves. Subgroup analyses interaction tests were also performed. Results During 6.65-year median follow-up, elevated showed independent associations increased all-cause cardiovascular mortality. Quartile-based analysis revealed 69 87% greater for highest versus lowest groups, respectively. RCS a non-linear threshold effect at = 14.5, beyond which risk sharply. demonstrated stable predictive accuracy, AUC ranging 0.664 to 0.607 0.652-0.609 over 3-10 years. confirmed consistency across different sex, BMI, lifestyle habits, comorbidity categories. Conclusion underscores strong positive correlation between prognosis older adult United States, indicating potential novel biomarker prognostic assessment.
