摘要
目的:探讨非梗死区心肌细胞凋亡在心室重构发生发展中的作用。方法:通过建立大鼠急性心肌梗死模型,采用超声心动图评价心室重构,TUNEL法检测细胞凋亡,观察心梗后3d、7d、14 d和28d心室重构与非梗死区心肌细胞凋亡的一系列演变过程,采用相关分析研究两者的关系。结果:梗死周边区的凋亡细胞数量和LVDd呈正相关(r=0.628,P<0.01),和LVEF呈负相关(r= -0.465,P<0.01)。远离梗死区的凋亡细胞计数和LVDd呈正相关(r=0.879,P<0.01),和LVEF呈负相关(r=-0.853,P< 0.01)。结论:梗死周边区和远离梗死区的心肌细胞凋亡在心肌梗死后心室重构的发生、发展中起了促进作用。
