hi all...the test this morning was no big deal...thankfully...getting an iv inserted was the worst part...the tech told me if i could walk on the treadmill slowly for four minutes it would dilute any possible side effects of the med they inject to chemically stress my heart and possibly give a better reading...so i was definately game for that...it was all very manageable...no side effects whatsoever...it was all over in 2 1/2 hours...now i'll have to wait to see my cardiologist to see if my coronary arteries are clear...what i really want to know is if the stem cells improved my heart function...i may have to wait for the final word on that but i'll keep posting...it's been sweet walking down steps one after the other!...best to all, rich
