Two and a half years after multiple heart attacks and subsequent open heart surgery (triple by-pass + defib implant), I am still declining on Muga tests -- now at 24. This isn't very positive news for a 51 year old with no previous or current risk factors. My doctors appear to be on top of most things but I would like to compare my list of medications to see if anyone thinks I should look at alternatives plus I appear to be suffering from an onset of arthritis, seemingly overnight, that is likely connected to one of these medications/treatments. I take Avapro, Toprol XL, Zestril, Hydrochlorot, and Coumadin plus a few supplements. My BP averages 90/50, my resting pulse is 50's, and when not suffering from the arthritis I walk two miles per day. My diet is very low fat, high in vegetables and fruit. My cholesterol has always been good (almost low) and I have, until now, led a very active life including sports. The original attacks were severe and may have been connected to clots they luckily found and treated before surgery and to-date they have no other idea what may have been the causes. The defib implant has not fired since install and has not recorded any pacing activity. Thanks for you help, nice forum. Beau
