摘要 心肌梗死是发达国家的主要致死因素之一 ,在我国随着生活习惯的改变及胆固醇摄取量的增加而增加。但对心肌梗死的研究及治疗因为没有合适的动物模型一直受到很大的限制。心肌梗死动物模型的研制及开发不但可以研究心肌梗死的发病机制以预防心肌梗死的发生 ,也将为制定新的治疗方案用于治疗心肌梗死提供理论依据。本文将回顾这一方面的国际进展情况 ,特别是将我们最近研制成功的自发型心肌梗死家兔模型作一重点介绍。此种家兔血中胆固醇水平明显升高 ,心电图发现心肌梗死的典型征象。病理组织学分析表明 ,此种家兔心肌梗死病变为陈旧性心肌梗死病变伴急性梗死病变 ,与人类心肌梗死相似。导致心肌梗死病变部位的冠状动脉呈严重的粥样硬化 ,狭窄程度达 90 %以上 ,且有些斑块为不稳定性斑块。
