摘要(Abstract)：
本实验在10只新西兰兔的活体心脏上,用Nd—YAG激光打孔后,结扎冠状动脉前降支;4只仅做前降支结扎.分别于术后3周、5周处死动物.在距激光孔道0—2mm,2— 4mm,及4—6mm等处的左室前壁心肌上共取标本30块.而仅结扎前降支兔于3周,5周处取10块,正常兔左室前壁心肌取标本20块.以虫荧光素法测量心肌组织中三磷酸腺苷(ATP),磷酸肌酸(CP)含量.发现术后3周激光孔道附近心肌组织中的ATP已接近正常心肌组织中的ATP含量(P>0.05),术后5周远离孔道部的ATP已较3周时有所恢复,但仍较正常低.CP较ATP恢复慢.表明:心肌血管再建术的确可起到心肌营养的作用.
