简介：
Overview
This article presents a myocardial infarction (MI) model in swine that closely mimics human disease, facilitating the study of pathophysiological mechanisms and therapeutic interventions. The model utilizes a percutaneous embolization coil, avoiding traditional open-chest surgery.
Key Study Components
Area of Science
- Cardiovascular research
