My 91 y/o father just had a spect stress test, results showed mild inferolateral ischemia. Non symptomatic, with an EF of 55%. He is a little bradycardic with rate 54-58 bpm. His is ESRD on dialysis, borderline type 2 diabetic very well controlled with oral meds. My question is, I do not think this is too serious for a man his age and is this expected age related? His cholesterol levels are great, better than mine , should I be overly concerned, also he is NSR.
