Abstract：Objective To discuss the curative effect and safety of drug-coated balloon(DCB)on unstable angina pectoris(UAP)based on optical coherence tomography(OCT).Methods UAP patients(n=50)diagnosed by coronary angiography(CAG)were selected from Hospital of Chinese PLA the 81st Group Army from July 2022 to Dec.2022.All patients were treated with percutaneous coronary intervention(PCI)under OCT guiding.The results of CAG,OCT and DCB expansion,and post-operative adverse reactions were observed in all patients.Results The time of DCB expansion continued for 60 s to 90 s(75±6 s).The degree of target vessel stenosis was significantly lower after DCB treatment compared with that before treatment(P<0.01).The minimum diameter of target vessel was(0.92±0.06)mm before the operation and(2.88±0.05)mm after the operation(P<0.01).All patients well recovered and discharged without relapsed angina pectoris and complications after PCI.Conclusion It is effective and safe for treating UAP with PCI by applying DCB based on OCT.
