摘要(Abstract):
目的 探讨体外膜肺氧合(ECMO)辅助下行经皮冠状动脉介入治疗(PCI)的高危复杂冠心病患者(CHIP)应用比伐芦定的安全性与有效性,以期为ECMO辅助期间抗凝治疗决策提供更多证据。方法 本研究回顾性连续纳入2019年3月至2022年12月在兰州大学第一医院心脏中心行静脉-动脉体外膜肺氧合(VA-ECMO)辅助PCI的CHIP 83例作为研究对象,根据ECMO辅助期间以及PCI术中抗凝药物使用情况,分为比伐芦定组(40例)和肝素组(43例)。比较两组患者抗凝药物费用、活化部分凝血酶时间(APTT)变异系数、APTT达标率、出血事件、血栓事件、血制品输注情况、术后30 d净不良临床事件(NACE)有无差异,以明确ECMO辅助下接受PCI的CHIP应用比伐芦定的安全性和有效性。结果 两组患者基线资料比较,比伐芦定组既往PCI(25.00%比4.65%)、纤维蛋白原[(3.52±1.14)g/L比(2.92±1.28)g/L]、CRUSADE评分[(32.00±12.69)分比(26.14±10.60)分]、抗凝费用[1 4 0 0.0 0(7 0 0.0 0,2 10 0.0 0)元比10 7.6 9(5 8.7 4,2 0 5.5 9)元]、A P T T达标率[(57.76±33.11)%比(31.44±27.63)%]均高于肝素组,APTT变异系数[10.64(7.72,21.11)比19.47(10.48,31.28)]低于肝素组,差异均有统计学意义(均P<0.05)。两组患者30 d NACE比较,比伐芦定组总出血事件发生率(25.00%比46.51%)、出血学术研究联合会(BARC)1~2型出血事件发生率(12.50%比32.56%)、总血栓事件发生率(12.50%比32.56%)均低于肝素组,差异均有统计学意义(均P<0.05)。Kaplan-Meier曲线显示,比伐芦定组30 d NACE累积发生率显著低于肝素组,差异有统计学意义(Log-rank P<0.001)。结论 在VA-ECMO辅助下接受PCI的CHIP,与肝素相比,比伐芦定具有更好的安全性和有效性。
