Re: Cardiomyopathy plus thyroid problem
- Hi Leslie,
Welcome to the group, though I'm sorry you and Zacky have to go through this. As Susan
said, it is "preferable" to have the hyper-t be the primary disease. Abby was diagnosed
hyper-t, HCM w/grade 3 murmur last March. She was also in full blown IBD, probably as a
result of the hyper-t. With proper hyper-t treatment, the HCM has resolved, though her
murmur is now classified as a grade 3-4/6. The IBD is, mostly, under control.
Some things to know:
It is better for the animal in question (human or feline) to have single dose hyper-t
therapy given in the morning. I don't know the particulars of why. I do know that my
pharmacist told me that it's important.
Atenolol may have a difficult adjustment period, but side effects usually go away.
It is also very important to follow pills or gell caps with at least 5cc's of water or a
small amount of food. If this isn't done, it can cause erosion in the throat and potentially
mesoesophagus. In our "FILES" section there is an article about this and it's title is "Erosive
Esophogitis.doc" and is worth the read.
You probably already know this, but it is important to get Zacky's T4 thyroid retested in 2
to 4 weeks and adjust the meds up or down if necessary. Initially we started Abby off at
2.5mg twice a day. It was too much for her and drove her T4 levels down to 0.1. We tried
2.5mg 1X day, and it was still too much. She is now on 1.25mg once a day.
There is a feline hyper-t group and you can find them at
