Is she on Entresto now? It is to avoid all sorts of problems associated with heart failure, such as this.
I don't know how well it works with other medications, but I do know that it works with carvedilol/Coreg (sp?), as that's the combination that they gave Dh when his heart failed, and went to less than 30%. He couldn't breathe, and other symptoms. One did not work for him. He has to take the combination. Also, there are various strengths, and he couldn't use the lower mgs.
Continuing to pray for Naylz.
