摘要：

目的通过与心肌桥本身介入治疗疗效的比较,观察心肌桥近端血管严重动脉粥样硬化病变的介入治疗疗效。方法试验组选择心肌桥近端动脉粥样硬化并严重狭窄(≥70%)者28例(A组),对照组选择有症状的单纯心肌桥改变且收缩期严重狭窄(≥95%)者16例(B组)和单纯前降支动脉粥样硬化严重狭窄(≥70%)者54例(C组),应用普通冠状动脉支架介入治疗。结果三组均成功行介入手术,三组支架置入后的血管内径及支架长度比较差异无统计学意义。A组6个月内4例(14.3%)再狭窄,B组6个月内7例(43.7%)出现再狭窄,C组8例(14.8%)再狭窄,A组和C组的再狭窄率差异无统计学意义,但均显著低于B组(P<0.05)。三组中再狭窄患者均再次接受介入治疗。结论心肌桥近端严重动脉粥样硬化病变的介入治疗疗效未受心肌桥近端异常血流动力学的影响。但心肌桥病变本身的介入治疗远期再狭窄率较高。
