Nuclear Myoview Stress Test Results

I don't understand my results.  ischemic changes due to ST-T wave abnormalities on resting electrocardiogram -1.7,-1.3,-1.4-,-1.1 -1.2 on certain leads.  Exaggeration of j-point depression at peak exercise.  90% age-predicted max heart rate  for pressure rate product 300, met capacity of 10.0 @ l minute following exer. protocol.  Post heart rate response of 127 represents 23 point drop in peak rate.  

On the nuclear part, no reversible ischemia.  Inferior wall fixed defect.  Left ventricular ejection fraction calculated at 57%.

The lack of reversible ischemia means that there are unliley to be any blockages to explain your symptoms (usually chest pain).  the inferior wall fixed defect most likely represents an artifact, however, if you'd had a heart attack in the past, that would also be consistent.  The fact that your heart function and exercise capacity are normal portends a favorable prognosis.
