摘要(Abstract):
为观察不稳定性心绞痛病人冠脉血管病变的特征,来指导正确的治疗。55例不稳定性心绞痛病人行冠脉造影结果提示:血管病变最轻的类型为变异型和自发型心绞痛,多为较轻的A型病变(85.7%),其心肌缺血主要原因为冠状动脉痉挛或张力性改变,首选钙括抗剂治疗。冠脉病变最重的是梗塞后心绞痛,多支血管病变发生率高且均为B、C型病变,应争取冠脉搭桥。初发心绞痛为严重单支血管病变,且侧支循环不丰富,可能存在心肌梗塞的危险,应积极药物或PTCA治疗。非Q波型心梗血管完全性闭塞的发生率明显高于其他类型(33.3%)(P<0.001),侧支循环在该类型中具有重要的保护作用,如药物治疗下仍有心绞痛发作,应行冠脉搭桥术保护存活心肌,维持心脏功能。
