- Abstract: Objective To analyze the efficacy of drug-coated balloon in the treatment of hetero-geneous in-stent restenosis.Methods A total of 118 patients who received treatment and diagnosed with heterogeneous in-stent restenosis were selected as study objects,and were divided into two groups using a random table method.The experimental group(n=59)received drug-coated balloon thera-py,and the control group(n=59)received drug-eluting stent therapy.The therapeutic effects of the two different treatment methods on heterogeneous in-stent restenosis were compared.Results There was no significant difference in the incidence of in-stent restenosis in the right coronary artery,cir-cumflex artery,and anterior descending artery between the two groups(P＞0.05).There was no sig-nificant difference between the two groups in the preoperative reference vessel diameter,lesion length,lumen stenosis degree,and localized restenosis(P＞0.05).The postoperative residual ste-nosis rate in the experimental group was significantly higher than that in the control group(P＜0.05).There was no significant difference between the two groups in the preoperative lumen area,neointimal load,stent inner area,neointimal area,incidence of neoatherosclerosis and thrombus(P＞0.05).Operative lumen area of the experimental group was smaller than that of the control group(P＜0.05).No target vessel reconstruction,stent thrombosis,nonfatal myocardial infarction,or cardiac death occurred in two groups during 12 months of follow-up.Conclusion Drug-coated balloons are effective and safe in the treatment of heterogeneous in-stent restenosis,and can obtain similar effects to drug-eluting stents.
