Hi Lee; I've always tested in the mid 50's since starting Herceptin, and my onc has always said he would only start to worry if it dropped below 50. As Maryanne points out, some who've had to take a vacation from Herceptin when their heart function dropped too low were then able to start up as their heart improved after a rest...
That said, I've been told that if the heart is going to show damage from Herceptin it will usually happen sooner rather than later, and if your mom is stable at 50 after 3 years it would be unusual for things to suddenly change at this late date, unless a new drug is introduced that would precipitate a change for the worse, and her docs will no doubt be watching for that.

<3,
Lolly
