Abstract
Despite enormous efforts in treating myocardial infarction (MI) and subsequent heart failure, the recent statistics from the American Heart Association evidently show that there still remains room for improvements. To develop and translate new therapeutics toward clinics, large animal models that allow us to test new therapies in human-like conditions are of extraordinary importance. In this chapter, we describe detailed protocols for the creation of a closed-chest MI model in pigs. The advantages of this model include high survival rate (>90% after ischemia–reperfusion), adjustable MI size depending on coronary occlusion site, reproducible cardiac dysfunction, and relatively low invasive method. The temporary coronary occlusion method for ischemia–reperfusion injury as well as the permanent occlusion method, using clot injection or embolic coil implantation, are described. Furthermore, we describe the key steps needed for understanding, performing, and analyzing cardiac angiography and echocardiography in pigs.
