Thank you for all of the replies! I had the MUGA scan 1 week after my 7th Herceptin infusion. I've been getting 600mg every 3 weeks. The treatments were given to me over a 30 minute period, so maybe that has had an effect. I'm glad to hear that they can make a mistake on the test, so thats what I'm hoping for. I'm a bit angry right now because the onc never sent me for a baseline test. The nurse that called me today expressed that was a big mistake because now we don't know if I already had a heart problem, or was this caused by Herceptin.
I'm somewhat overweight, but I never thought I was in that bad of shape because I work 10 to 12 hours a day, 6 days a week, and I'm on a dead run, hardly getting to set down. I have also went close to 18 years without a vacation, except for the week I took off after the mastectomy, and 2 weeks after the lymph node surgery. I never really got that tired before, but for the last couple of weeks I've been getting very tired and sometimes out of breath when just taking a short walk. I guess now I know why.......
