简介:摘要目的为研究三门峡地区行经皮冠状动脉介入治疗(percutaneouscoronaryintervention,PCI)术患者,药物洗脱支架(drug-elutingstentsDES)和金属裸支架(baremetalstentsBMS)支架内血栓形成(stentthrombosisST)的发生率。急性血栓在24h小时发生,亚急性血栓在30天内、一年或者超过一年发生。方法所有患者患有急性冠脉综合症或者不稳定心绞痛,所有患者病情是PCI术适应症,无禁忌症。均在介入中心行PCI治疗。结果全部1386个行PCI术患者中,有19个(1.3%)有支架内血栓形成,其中4个人(21%)植入DES,15人(79%)植入BMS。4个人有支架内急性血栓形成,5个人有亚急性血栓形成,8个人有晚期血栓形成。同时9个病人有糖尿病,8个病人有高血压。结论三门峡地区在我们介入中心植入DES的患者支架内血栓形成的发生率与国际上报道的人数相似。支架内血栓形成的病人当中几乎一半患有糖尿病。倍受医生关注的是晚期支架内血栓形成的风险DES偏高于BMS。
