Hello, my husband is having some problems with dizziness . He has had a CT scan, which was negative, blood work which was normal, a walking stress test without and with dye. His doctor called to say the stress test showed irreversible changes in the heart function and has referred him to a specialist. What does this mean? The doctor did not give us any other information.
Hello, I would explain that this could indicate possible heart failure or a past myocardial infarction.  I would like to directly review his cardiac ultrasound report and resting ECG for a more professional opinion.  Hope I have answered your query. Let me know if I can assist you further.
