[A case of stunned myocardium determined by nuclear cardiac imaging]

A 75 year old woman with acute chest pain was diagnosed as unstable angina. Anterior akinesis of left ventricule and small anterior perfusion defect were found by 99mTc blood pool imaging and 201Tl myocardial imaging. Coronary arteriography showed no organic stenosis, though anterior akinesis was still continued. Furthermore this akinesis and perfusion defect by 201Tl were all disappeared two weeks later. Thus, we determined this case as a stunned myocardium followed by severe angina with transient coronary obstruction.
