摘要 目的观察阿托伐他汀对心肌梗死后心肌重塑的影响。方法按照随机方法分为两组:假手术组和手术组,手术组心肌梗死模型建立成功后再随机分为心肌梗死组和阿托伐他汀组。在标准饲养方法的基础上,每天对每只大鼠灌胃1.0ml双蒸水,其中阿托伐他汀组大鼠灌胃液中含阿托伐他汀(立普妥)5mg/(kg.d),其余组灌胃液中无任何药物。给药时间持续4周。测定非梗死区心肌组织TNF-α浓度、MDA的浓度,测定心室肥厚指数及心肌细胞凋亡指数。结果AMI对照组和阿托伐他汀干预组心室肥厚指数及心肌细胞凋亡指数明显高于假手术组,阿托伐他汀干预组显著低于AMI对照组。非梗死区心肌组织TNF-α浓度、MDA的浓度与心肌细胞凋亡指数呈正相关。结论阿托伐他汀可以减少心肌梗死后心肌细胞凋亡,改善心肌重塑和心功能。
