摘要(Abstract)：

目的分析接受主动脉内球囊反搏(IABP)辅助行经皮冠状动脉介入治疗(PCI)急性冠状动脉综合征(ACS)合并心源性休克患者的特征及预后情况。方法回顾性分析北京安贞医院2014年1月至2015年12月应用IABP辅助行PCI的ACS合并心源性休克患者197例,根据患者生存情况分为存活组(162例)和死亡组(35例),比较两组患者的临床特点及住院不良事件的发生情况。结果 197例患者平均年龄(57.3±14.7)岁,入院时平均动脉压(53.3±14.6)mmHg(1 mmHg=0.133 kPa)。两组患者入院时性别、吸烟、高血压病、高脂血症、肌酸激酶同工酶(CK-MB)、血肌酸酐比较,差异均无统计学意义(均P>0.05);而存活组患者年龄、2型糖尿病、陈旧性心肌梗死、心肌肌钙蛋白I(cTnI)水平显著低于死亡组(均P<0.05)。IABP置入前后,存活组患者收缩压、舒张压、平均动脉压、心脏指数的升高水平显著大于死亡组,差异均有统计学意义(均P<0.05);而两组患者心率、动脉血氧饱和度的升高值比较,差异均无统计学意义(均P>0.05)。两组患者罪犯血管在左前降支、左回旋支、右冠状动脉,完全血管化,TIMI血流Ⅲ级,症状发作-球囊扩张时间,进门-球囊扩张时间比较,差异均无统计学意义(均P>0.05);存活组患者罪犯血管在左主干比例、术后24 h CK-MB值、术后24 h cTnI值显著小于死亡组,差异均有统计学意义(均P<0.05);而ST段回落>50%比例显著大于死亡组患者,差异亦有统计学意义(P<0.05)。存活组患者再发心肌梗死、急性肾损伤、床旁血滤、有创机械通气发生率及住院时间显著低于死亡组患者,差异均有统计学意义(均P<0.05);而两组患者血管活性药使用率比较,差异无统计学意义(P>0.05)。结论 ACS合并心源性休克患者进行IABP辅助PCI存在较高的不良事件发生风险。死亡组患者表现为高龄、合并2型糖尿病及陈旧性心肌梗死,且存在较高的再发心肌梗死、急性肾损伤等住院不良事件,对该类患者应强化院内监护,警惕不良预后的发生风险。
