摘要 目的:评价来氟米特对急性心肌梗死(AMI)的治疗作用及其机制,为冠心病防治寻找新药物提供实验依据。方法:将体重1.5~2.5kg的成年兔36只随机分为对照组(A组),来氟米特组(B组)及普伐他汀组(C组),建立AMI的模型并给予相应的干预,作术后6h血液学观察,4d及4周时分别作血液、血清、血流动力学、大体形态测量及组织学的观察。结果:B、C组与A组比较,6h﹑4d及4周时WBC明显下降(P<0.05),一氧化氮(NO)术后4d及4周时3组无明显差异(P>0.05),丙二醛、心房钠尿肽、左室功能测定值、左室舒张末压B、C组均明显下降(P<0.05)。术后4d时B、C组梗死面积明显下降(P<0.05),4周时瘢痕面积明显下降,瘢痕厚度较A组略薄(P<0.05)。组织学检查显示梗死区术后4d时A组WBC浸润程度大,坏死心肌结构消失,B、C组梗死区中浸润程度显著减轻,残存少量坏死心肌结构及一定存活心肌组织。结论:AMI使用来氟米特后,兔死亡减少,心功能改善,WBC、梗死及修复后的瘢痕面积减小,仅瘢痕厚度略变薄,提示来氟米特治疗AMI可能具有一定的疗效。
