Outline of Final Research Achievements

Recently developed 3D speckle tracking echocardiography (3D-STE) has the potential to address the several issues of ischemic memory imaging by the 2D speckle tracking technique. We evaluated whether 3D-STE could be used for the assessment of myocardial ischemic memory with the animal experiments. In the results, subtle abnormal myocardial motion could be detected by 3D-STE after recovery from ischemia. In conclusion, we think that 3D-STE can assess myocardial ischemic memory.
