I also had a drop in my heart fx after 8 months of herceptin. It went from 82% pre treatment to 54%. Since I was still above the 50% mark, I had 2 more herceptin infusions and then another MUGA. This time it went up to 63%.
Chrisy, I am interested in what you said about the timing of the MUGAs. It there a study or any articles about that? I know it is true for me. When my ejection fraction was lower I felt very different. A cardiologist friend said the heceptin stresses the heart cells and they don't contract the way they should to get a strong heart beat. He recommended to still exercise but not to stress my heart (so no sprinting in the swimming pool like I used to do). I'm just trying to chill out and get through the next couple infusions but that's not very easy-just want to get past this part and get that pesky port out.
