摘要
目的分析药物洗脱支架植入后晚期支架内血栓形成(LST)及超晚期支架内血栓形成(VLST)事件的发生率以及临床相关因素。方法长期随访西罗莫司洗脱支架治疗的1 504例患者,分析发生LST的8例患者以及VLST的14例患者的基本临床特征、冠状动脉病变特征及支架植入情况、支架内血栓的发生及治疗情况等。结果西罗莫司洗脱支架置入术后,LST发生率为0.5%(8/1 504),发生于术后(206±85)d,VLST发生率为0.9%(14/1 504),发生于术后(996±611)d。发生支架内血栓患者与未发生晚期支架内血栓患者比较,高血压、糖耐量异常、吸烟、因急性冠脉综合征入院、闭塞病变、分叉病变、弥漫长病变、多支血管病变、植入长支架、多枚支架的发生率差异有统计学意义(P<0.05)。LST与VLST患者比较,胰岛素依赖的糖尿病、吸烟、高血压病的发生率以及发生血栓时的抗血小板治疗的方案差异有统计学意义(P<0.05)。对14例LST和VLST患者中2例行血栓抽吸延迟PCI治疗,余均行直接PCI治疗,所有患者均再次行药物洗脱支架植入术,目前随访均存活。结论高血压、糖耐量异常、吸烟、因急性冠脉综合征入院、闭塞病变、分叉病变、弥漫长病变、多支血管病变、植入长支架、多枚支架是患者发生支架血栓的相关因素,其中糖尿病、吸烟对于VLST的影响不同于LST;支架内血栓形成患者行血栓抽吸及再次植入支架安全、有效。
