Abstract
Background: Percutaneous superficial femoral interventions remain the preferred method of treatment for superficial femoral artery (SFA) disease. Nevertheless, long term restenosis continues to be a major limitation of percutaneous interventions. In this context, the objective of this study is to compare the efficacies of CHA2DS2-VASc, CHA2DS2-VASc-HS, ATRIA, ATRIA-HSV, and HATCH risk scoring systems in predicting long-term (5 years) restenosis due to percutaneous interventions to the superficial femoral artery. Patients and methods: The sample of this retrospective study consisted of 545 peripheral artery disease (PAD) patients with a percutaneous intervention to the SFA. Of these patients, 362 and 183 were included in the group of PAD patients without long-term (5 years) SFA restenosis (Group 1) and in the group of PAD patients with long-term SFA restenosis (Group 2). The efficacies of CHA2DS2-VASc, CHA2DS2-VASc-HS, ATRIA, ATRIA-HSV, and HATCH risk scoring systems in predicting the development of long-term SFA restenosis were comparatively analyzed. Results: CHA2DS2-VASc, CHA2DS2-VASc-HS, ATRIA, ATRIA-HSV, and HATCH risk scores all increased with long-term SFA restenosis. The receiver operating characteristic (ROC) curve analysis revealed that all five risk scoring systems successfully predicted long-term SFA restenosis, whereas the paired ROC curve analysis revealed that CHA2DS2-VASc-HS scores of >4 had the best prognostic power in predicting long term SFA restenosis. Conclusions: The study findings indicated that the CHA2DS2-VASc-HS score was an independent predictor of the development of SFA restenosis. The CHA2DS2-VASc-HS risk scoring system, which is the modified version of CHA2DS2-VASc, outperformed the CHA2DS2-VASc, HATCH, ATRIA, and ATRIA-HSV, the modified version of ATRIA, risk scoring systems in predicting long-term (5 years) SFA restenosis.
