ObjectiveTo investigate association between the nutrition-related indicators and the recurrence of venous thromboembolism (VTE). MethodsA retrospective analysis was conducted on the clinical data of VTE patients admitted to West China Hospital of Sichuan University from January 2020 to October 2022. The multivariate logistic regression was used to assess the association between the nutrition-related indicators (albumin to fibrinogen ratio or prognostic nutrition index) and VTE recurrence. The test level was set as α=0.05. ResultsA total of 141 VTE patients were enrolled in this study, of whom 12 (8.5%) experienced recurrence within 2 years. The multivariate logistic regression analysis identified several risk factors for recurrence, including diabetes [β=–3.368, OR (95%CI)=0.034 (0.001, 0.920), P=0.044], pulmonary embolism [β=–0.454, OR (95%CI)=0.635 (0.423, 0.954), P=0.029], and the decreased albumin-to-fibrinogen ratio [β=–0.153, OR (95%CI)=0.858 (0.722, 1.020), P=0.083]. ConclusionThe results of this study suggested that diabetes, pulmonary embolism, and decreased albumin-to-fibrinogen ratio are identified as risk factors for VTE recurrence.
