目的 比较紫杉醇洗脱球囊(PEB)与依维莫司洗脱支架(EES)治疗不同类型冠状动脉小血管病变的临床效果。方法 连续入选2015年1月至2016年1月于首都医科大学附属北京安贞医院择期接受经皮冠状动脉介入治疗的261例小血管病变(直径≤2.5 mm)患者。根据实际介入操作情况分为PEB组(67例)和EES组(194例);根据病变长度分为局灶型病变(≤10 mm)和非局灶型病变(>10 mm)。通过门诊或电话随访,主要研究终点为术后12个月时的靶病变再次血运重建(TLR);次要研究终点为12个月时的主要心血管不良事件(MACE),包括TLR、非致死性心肌梗死、全因死亡等。结果 PEB组双联抗血小板治疗时间明显短于EES组[(4.6±1.1)个月比(11.7±2.1)个月],差异有统计学意义(P<0.01)。随访12个月时,PEB组和EES组TLR和MACE发生率比较[9.0%(6/67)比10.8%(21/194)、10.4%(7/67)比12.3%(24/194)],差异均无统计学意义(均P>0.05)。在局灶型病变患者中,PEB组TLR和MACE发生率明显低于EES组[4.2%(1/24)比14.3%(8/56)、4.2%(1/24)比16.1%(9/56)],差异均有统计学意义(均P<0.05)。在非局灶型病变患者中,PEB组TLR和MACE发生率略高于EES组[11.6%(5/43)比9.4%(13/138)、14.0%(6/43)比10.9%(15/138)],但差异无统计学意义(P>0.05)。结论 PEB治疗局灶型冠状动脉小血管病变的临床效果优于EES,并且能明显缩短双联抗血小板治疗时间。
【Abstract】Objective To analyze the effects of paclitaxel-eluting balloon(PEB) and everolimus-eluting stent(EES) on coronary small vessel disease. Methods Totally 261 patients with small coronary artery disease(diameter≤2.5 mm) were enrolled from January 2015 to January 2016 in Beijing Anzhen Hospital, Capital Medical University; 67 patients were treated by PEB(PEB group) and 194 patients were treated by EES(EES group). Coronary lesion was divided into focal lesion(length≤10 mm) and non-focal lesion(length>10 mm). All patients were followed up for 12 months; the primary endpoint event was target lesion revascularization(TLR); the secondary endpoint events included major adverse cardiac events(MACE), TLR, nonfatal myocardial infarction and all cause death. Results Duration of dual antiplatelet treatment in PEB group was significantly shorter than that in EES group[(4.6±1.1)months vs (11.7±2.1)months](P<0.01). Incidences of TLR and MACE showed no significant differences between PEB group and EES group[9.0%(6/67) vs 10.8%(21/194), 10.4%(7/67) vs 12.3%(24/194)](P>0.05). In patients with focal lesion, incidences of TLR and MACE in PEB group were significantly lower than those in EES group[4.2%(1/24)vs 14.3%(8/56), 4.2%(1/24) vs 16.1%(9/56)](P<0.05). In patients with non-focal lesion, incidences of TLR and MACE had no significant differences between PEB group and EES group[11.6%(5/43) vs 9.4%(13/138), 14.0%(6/43) vs 10.9%(15/138)](P>0.05). Conclusion PEB is more effective than EES in treatment of small coronary artery disease and it can shorten the duration of dual anti-platelet treatment.
