ObjectiveThe aim of this study was to investigate the quality of life for patients with in-stent restenosis after interventional therapy of peripheral artery disease and the influencing factors.MethodsA total of 72 in-stent restenosis patients after interventional therapy of peripheral artery disease were enrolled, whose general data were obtained. SF-12 scale was used to evaluate the quality of life. Tilburg Frailty Scale was used to assess senile debilitation. Pittsburgh Quality Index Scale was used to evaluate sleep quality. Activity of Daily Living Scale was used to evaluate the self-care ability. The general data and in-stent restenosis-related indicators were compared between patients with low and high quality of life, respectively. Multivariate regression analysis was made on the factors affecting quality of life.ResultsThe average total quality of life score of 72 patients was 74.06±19.26 points. The gender, Fontaine stage and smoking, Activity of Daily Living Scale score, painless walking distance, senile debilitation score, sleep quality score, white blood cells, and C-reactive protein had significant differences between the two groups, respectively (p<0.05). Multivariate regression analysis showed that the female gender, low Fontaine stage (OR=0.186), low senile debilitation score (OR=0.492), and high sleep quality score (OR=0.633) were the protective factors for high quality of life (all p<0.05), and the low Activity of Daily Living score (OR=1.282) was the risk factor for high quality of life (p<0.05).ConclusionQuality of life of in-stent restenosis patients after interventional therapy of peripheral artery disease is low. Gender, Fontaine stage, senile debilitation, sleep quality, and Activity of Daily Living score are the influencing factors of quality of life for in-stent restenosis patients.
