Abstract

In an acute phase of myocardial infarction, size of the ischemic area may change depending on the collateral blood flow. Because the ischemic area of the myocardium is colder than normal surrounding tissue due to the decreased blood supply, the cold area can be identified by thermographic imaging. We have applied the thermographic identification of the cold area to an acute myocardial infarction model in dogs, and developed the system for continuous and realtime evaluation of the blood flow on an ischemic myocardium together with the hemodynamic changes.
