Did anyone tell you that all or part of this info could be totally wrong? If not, they done you a great disservice. Stress tests are basically used to determine if you have proper perfusion (blood flow) to your heart muscle. Was anything mentioned about ischemia (lack of blood flow)?
Sorry for all the bad news,

The hypokinesis means you have abnormalities in wall motion of the left ventricle. Coronary artery disease or any number of things could cause this. If you have no symptoms like shortness of breath on walking stairs or other minor exertion then it would seem that your overall heart function is still pretty good. Fatigue is a classic symptom with many heart related problems. Are you on any meds that might be adding to the fatigue?
