Chop Chemo/Heart Problems

I was diagnosed with mediastinal diffuse B cell NHL stage 2B in 1999 and have been cancer-free since completing chemoradiation.  I was treated with CHOP and then 21 cycles of radiation. I have done a little research and have seen that heart problems can occur from both adriamycin and radiation treatment.  Has anyone heard of or had heart complications like this following CHOP? Or how about breast cancer? Is anyone familiar with MUGA scan to evaluate for heart/cardiovascular problems? Any help would be greatly appreciated.  Thanks.

Hello:  inreply to your message about heart problems after chops, yes it does cause this, but you will need to see a heart doctor and he will give medicine to make you feel better.  If i can be of any more help please do not hesitate to write!!! 

I also had the chop and radiation and yes ive been having breathing and heart problems I had several muga scans and it shows really nothing Ive seem my lung doctor and somethims my blood numbers are weird and sometimes normal until something major happens to me no one can seem to do anything for me but please ask to have a muga scan its painless and it can at least put your mind at ease for now.  sincerely liann in las vegas
