摘要
目的探讨经皮冠状动脉介入治疗(PCI)后围术期并发心肌梗死(PMI)患者的发生原因及临床特征。方法将PMI患者44例与同期行PCI的213例冠心病患者对比分析。结果①PMI患者合并糖尿病者较多(36.4%和27.2%,P=0.016);血清总胆固醇[(5.69±1.73)mmol/L和(4.47±1.61)mmol/L,P=0.041]和低密度脂蛋白胆固醇[(3.17±1.15)mmol/L和(2.67±0.98)mmol/L,P=0.032]较高、高密度脂蛋白胆固醇[(0.41±0.08)mmol/L和(0.53±0.24)mmol/L,P=0.049]较低;冠脉病变积分较高(12.75±5.61和8.96±3.68,P=0.027)、左主干(9.1%和4.2%,P=0.001)和多支病变(63.6%和41.8%,P=0.002)均多于非PMI组。②两组患者PCI成功率(95.5%和94.8%,P=0.523)相当,PMI并发边支闭塞(11.4%和3.8%,P=0.001)和慢(无)血流者(34.1%和13.1%,P=0.001)较多;球囊扩张时间长[(15.4±5.9)s和(8.7±2.4)s,P=0.026]、次数多(3.1±1.2和1.5±0.6,P=0.003),扩张压力无差别[(114.2±26.3)kPa和(98.0±35.4)kPa,P=0.752];支架置入较多(2.8±1.1和1.3±0.4,P=0.037)和X线曝光时间较长[(102.3±14.5)min和(67.9±23.4)min,P=0.002]。结论PMI患者在术前多具有高血糖、高血脂的危险因素,冠脉病变复杂、高危,术中多次、长时间扩张病变和并发边支闭塞及慢(无)血流是其发生PMI的主要原因。
