<s>[INST] I would like to understand my MIBI stress test results Findings: The overall quality of the study was Adequate. SPECT images demonstrate small mild anterior perfusion defect on stress images which non reversible at rest, however normal wall motion is seen, as well as breast shadow and vertical patient motion. Gated SPECT images demonstrate normal wall motion. Left ventricular ejection fraction was calculated to be 67% at rest and 65% post-stress. [/INST] Hi I have gone through your question I think you are worried about that small fixed defect it indicates some previous ischemic insult which result in scar myocardium but as the area is small one and by small I will assume it's less than 5% only involve one arterial territory and not effecting your overall ejection fraction take your cardiac meds and exercise and less cholesterol regular check up with your physician and don't worry remember once defect is fixed the myocardium cannot be salvaged thanks hope answer your question </s>
