This study aimed to evaluate the predictive role of the CHA(2)DS(2)-VASc score for lesion severity and long-term survival outcomes in individuals with peripheral artery disease (PAD). Method: This retrospective analysis included 784 patients diagnosed with PAD via computed tomography (CT) angiography, consecutively enrolled from two medical centers. The CHA(2)DS(2)VASc score was determined for all participants. Lesion severity was assessed according to the TASC II (Trans-Atlantic Inter-Society Consensus II) criteria, and patients were categorized into TASC-AB (simple) and TASC-CD (complex) lesion groups. Mortality data were obtained from hospital and social security records. Results: The study included 784 patients (average age: 61.7 +/- 9.9 years; 17.2% female). In the regression analysis performed to predict lesion severity, we found that the CHA(2)DS(2)-VASc score (P < 0.007) and left ventricular ejection fraction (P = 0.009) were independent predictors. The receiver operating characteristic (ROC) curve indicated that a CHA(2)DS(2)-VASc score threshold of 3.5 predicted long-term mortality with 70% sensitivity and 79% specificity (P < 0.001). Kaplan-Meier survival estimates indicated that patients with higher CHA(2)DS(2)-VASc scores had significantly lower survival rates over the 60-month follow-up period (P < 0.001). Conclusion: The CHA(2)DS(2)-VASc score was independently associated with both lesion severity and adverse long-term outcomes in individuals with PAD.en10.5543/tkda.2025.66505info:eu-repo/semantics/openAccessCHA2DS2-VASC ScoreLesion ComplexityMortalityPeripheral Artery DiseaseArticle2-s2.0-105025219312
