Excel雷帕霉素药物洗脱支架临床应用安全性及疗效评价

目的:探讨国产Excel雷帕霉素药物洗脱支架对冠心病患者介入治疗的安全性和近中期疗效。方法:2006年7月~2009年6月共对240例冠心病患者进行介入治疗。术后随访6~24个月,观察有无心绞痛、心肌梗死、猝死及再次血管重建事件。结果:272处病变血管(de novo病变269处,再狭窄病变3处)共使用327枚Excel支架,成功置入支架325枚,2例患者支架置入失败(1例前降支近中段病变严重钙化扭曲,支架不能通过病变;1例回旋支中段病变成角大于90度,支架不能通过成角血管),置入支架成功率99%,5例分别于术后8~18个月出现心绞痛症状,复查造影发现2例发生支架内再狭窄,3例血管造影未见支架再狭窄。1例术后5个月出现疑似晚期支架血栓形成(发生心室颤动)。4例患者术后6个月左右发生上消化道出血,其中1例住院输血治疗。术后6~24个月内主要不良反应事件发生率4.58%。结论:Excel雷帕霉素药物洗脱支架治疗冠心病,具有良好的安全性和满意的近中期临床效果。
