摘要 目的^(99m)Tc-MIBI+^(18)F-FDG静态心肌血流灌注-代谢显像评价心肌梗死后,患者有无存活心肌以及存活心肌对左心功能的影响。方法本组受检心肌梗死患者60例,根据超声心动图左心室射血分数(LVEF)分为心功能不全组33例,心功能正常组27例,行^(99m)Tc-MIBI+^(18)F-FDG静态心肌血流灌注-代谢显像。结果心功能不全组静态心肌灌注缺损102节段,代谢缺损82节段。心功能正常组静态心肌灌注缺损67节段,代谢缺损32节段。心功能不全组灌注代谢匹配45%(15/33例);灌注代谢不匹配55%(18/33例);心功能正常组灌注代谢匹配30%(8/27例),灌注代谢不匹配70%(19/27例)。心功能不全组灌注记分(SPS)平均25.34±13.17,代谢记分(SMS)平均21.97±9.63,严重度记分(SSS)平均1005.25±596.01;心功能正常组SPS平均19.95±9.51,SMS平均14.35±8.97,SSS平均525±350.46。2组的LVEF与心肌灌注缺损的节段数、代谢缺损的节段数以及半定量SPS、SMS和SSS均呈负相关关系。LVEF与病变冠状动脉的支数无明显相关关系。结论心功能不全组的梗死区存活心肌明显少于心功能正常组。心肌梗死后有无存活心肌对心功能有较大影响。
