Hello Marie,
I was on Herceptin for 6 years and my heart stayed steadily ok.
However, due to radiation, 9 years after the radiation I had a heart attack and it was found that an artery had collapsed - it was within the radiation tattoo and I was told that was the cause. It was not the left side of the heart but in the center of my chest. I now take Bisoprolol and have had a stent put in.
I assume you are also being followed by a heart specialist.
I don't really know if it helps or is it's good to take or not, but several people on the site take co-enzyme q10 for the heart and I did all through taking Herceptin and in fact I'm now taking it again. Perhaps you could ask the cardiologist if it would help or if it would be harmful? My cardiologist also has me on a pharmaceutical grade fish oil called Omocar.
Hope your heart gets back in shape and you can get back on Herceptin.
Hugs
Sarah
