NON-HUMAN ANIMAL MODEL OF MYOCARDIAL INFARCTION AND METHOD FOR CREATING THE SAME

摘要

The present invention provides a non-human animal model of myocardial infarction, which can be created by a less invasive method, shows an extremely low mortality during and after surgical induction of myocardial infarction, ensures the blood reflow after necrosis of cardiac muscles caused by blocking blood flow, and therefore, is usable in topical therapy for myocardial infarction and studies on regenerative medicine. The present invention also provides a method for creating the non-human animal model comprising administering a temporary embolic agent to a branch blood vessel of a heart coronary artery to block blood flow in the branch blood vessel; and after a definite period of time after said vascular branch blockage, administering a temporary embolic agent to the target coronary artery which is intended to induce myocardial infarction to block blood flow in the target coronary artery.
