EF and therapies
An EF of 50 is generally considered the lower range of normal, Duga. But even so, often there is some degree of recovery after being taken off Herceptin. Many people here use CoQ10 daily to help with heart maintenance.
I live out in the boonies, but it is standard practice here to have either a MUGA or echo as a baseline prior to starting drugs affecting the heart like Adriamycin or Herceptin.
Wishing you the best,
