This interesting article mapped myocardial remodeling in swine after induced MI using serial 3D MRI imaging. Principal strain magnitude and angle were measured, and demonstrated progressive decrease in magnitude and angle rotation away from the site of injury, resulting in adverse remodeling and decreased contractility.
