【摘要】 目的 用老年大鼠建立一種與人類發病年齡相符的穩定可重復的急性心肌梗死動物模型。 方法 Wistar大鼠經戊巴比妥鈉麻醉后，氣管切開插管，連通呼吸機，開胸后結扎左冠狀動脈前降支。分不同時間點測血流動力學后取出心臟行病理組織學觀察。 結果 成功建立老年大鼠心肌梗死模型并進行病理組織學驗證。 結論 建立老年大鼠心梗模型是可靠的，有助于指導臨床實踐。【Abstract】 Objective To develop a steady and repeatable acute myocardial infarction model in old rats in accordance to human age. Methods Wistar rats were anaesthetized with sodium phenobarbital. After tracheotomy intubation, respiration machine was linked. Left anterior thoracotomy was performed to ligate the left anterior descending coronary artery. After hemodynamic parameters were obtained at various time points, hearts of the rats were taken for pathologic and histological examinations. Results The model of acute myocardial infarction in old rats was established successfully and proved by pathologic and histological staining. Conclusion It is reliable to establish the myocardial infarction model in old rats, which is helpful in guiding clinical practices.
