Hi, Griffin our beautiful 3.5 yr. old persian, was just diagnosed
with mild HCM. Last year this time, we were told he only had a
mildly increased left ventricular outflow velocity. Just 3 weeks
ago, a year almost to the date later, he has septal wall thickening
and there is a turbulant flow in the left ventricular outflow tract.
The left and right ventricular outflow velocitites show a dynamic
obstruction pattern. And, thre is a small amount of mitral valve
regurgitation and mild atrial enlargement. His right heart is
Ok, the problem is he is extremely sensitive to medications in
general. His cardiologist prescribed a beta blocker (atenelol) for
him and it made him so lethargic, even after backing his dosage way
down to 2mg. once a day. We discontinued it this past Tuesday and
he started perking up again. Saturday, just 4 days later he vomited
hairball (which is not unusual for him) and then he actually
fainted. My husband had to shake him rapidly to get him to come to.
He finally did and we took him to our vet and all seemed ok. My huge
concern here is that the atenelol lowered his blood pressure too
much or depressed his system, although I am just not sure. His
cardiologist does not know about this incident yet, but the last
time I talked to her she wanted to discontinue the atenelol, let a
week go by to get it completely out of his systemn, and then try
another beta blocker.
Please tell me if you think that a new beta blocker will have the
same effect. Is there anything else we can try that will help his
heart disease, but will not have such a negative impact on him
overall? I have read a little about natural remedys. Is this
something we should look into for him? Please, any advice given
would be extremely helpful.
FYI: before we took him for his 1 year re evaluation heart
ultrasound, he was acting completely normal. All of the stress from
vet visits and meds that don't agree with him, has made him moody
and a little withdrawn from us and generally quieter than normal. I
mean is it possible to let him stay off of beta blockers and keep
the disease somewhat in check? Because, I don't know if it is not
worse to continue stressing him with different meds and vet visits
and so forth. His heart rate is much slower here at home than at the
vets. I know they strive for around 120. He is somwhere between 140-
150 off of the meds.
Again, thank you for taking the time to read and any experiences
shared or advice given would be so much appreciated. I am scrambling
to find the right answers. Thank you, Amanda
