Comparison of the risk scoring systems in long term restenosis due to percutaneous interventions to the superficial femoral artery.

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. 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. 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. 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.
