Surgical protocol for permanent ligation of the left anterior descending coronary artery in mice to generate a model of myocardial infarction.

Myocardial infarction (MI) is one of the most common causes of death worldwide. Animal models for MI are useful for studying the pathophysiology and developing therapies. Here, we describe a surgical protocol for permanent ligation of the left anterior descending coronary artery in mice, which mimics human acute coronary syndrome. This protocol includes descriptive step-by-step surgical procedures and high-quality surgical videos, which are useful for performing stable and highly reproducible operations. For complete details on the use and execution of this protocol, please refer to Maruyama et al. (2021).
