What Does This Stress Test Result Signify?

Hello, I received my cardiac perfusion stress test w/treadmill results. Findings: There is a large, severe and persistent perfusion defect involving the apex, mid to apical anterior, lateral apical, and inferior apical segments. This is adjoined by a moderate-sized, moderate to severe, and persistent perfusion defect involving the basil to mid septal segments. There are no reversible or other fixed perfusion defects. the summed up score is 25. The quantitative three-dimensional reconstructed cine images demonstrate dyskinesis of the septum and apex and otherwise normal left ventricular contractility. The post-stress/rest left ventricular ejection fractions are 42/53% with end diastolic volumes of 199/197 and 116/92 mL, respectively. I had an AMI with 100 percent occlusion in April. Recent echocardiogram results put me at 25-30 percent LVEF. This is at variance with Thallium Nuclear test. I feel good and my treadmill was way above average. Seems like part of my heart is dead, but I don t know how to interpret these results. Can this be put into lay terms - e.g., percent of heart damage, which reading of LVEF is reliable, mortality? I am 55, non-smoker, exercise every day, eat perfectly, 5 10, 170 pounds. Mahalo
