Abstract:
Objective To establish a standardized mouse myocardial infarction model,and non-invasively evaluate its cardiac function by using the echocardiography.Methods A total of 20 wild male mice were enrolled into this study.The left anterior descending coronary was ligated through the left fourth intercostal space after intubation.The echocardiographic assessment of myocardial infarction and heart function was performed 3 days preoperatively and 2 weeks postoperatively.The shortening fraction(FS),end systolic dimension(ESD),and end diastolic dimension(EDD) was recorded and analyzed.Results The acute and one-week mortality rates were 20%(4/20) and 40%(8/20),respectively.The echocardiography showed that the myocardial infarction model was successfully established in 10 mice.The heart function of the mice was markedly impaired.The FS significantly decreased from(50.23?8.36)% to(25.41?0.97)%(t=16.18,P
