Re: cardiac PET scan

Dr.Andrew B.Chung I do not know what was the exact peak or maximal
heart rate before the drop,but I do know that it was over 100% predicted
maximal heart rate.If a person is 47 yrs old 6 feet tall and weighs 186
pounds what would peak heart rate before the drop have to be for drop
in heart rate of 66 beats to be considered normal (and better than all
<66 beats)?The following questions are about the question that you
already answered. Dr.Andrew B.Chung you said that cardiolite scan with a
defect and a normal FDG PET and EKG do not rule old heart attacks (dead
muscle tissues).I thought that cardiac FDG PET is the best test to look
for the extent of dead muscle tissues,otherwise why would it be used in
cardiac viability studies. Do you think resting cardiolte (sestamibi)
images demostrating a mild reduction in tracer accumulation is better
test to rule out old heart attacks (dead muscle tissues not blockages)
than FDG PET images demostrating a disproportionately increased amount
of FDG tracer accumulation in the same region in comparison to the
degree of cardiolite (sestamibi)? Are you saying that cardiolite resting
images are better than cardiac FDG PET images in detecting old cardiac
dead muscle tissues and please,will you explain what this means and be
very clear?Thanks
