My cat has HCM. What are the best treatment options for her heart?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Male | neutered | 11 years and 1 month old | 17 lbs

Diagnosed bronchitis, HCM (LA sev. dilated), and CHF via X-ray and echo. 2nd set X-rays 3 days later showed improvement in lungs. Discharged on clopidogrel, clavamox, lasix, fluticasone. Resp.rate ~ 25. Drinking, eating small amounts, urinating. F/U appointment 1 week. I see atenolol is regularly used in HCM patients after CHF is controlled with no fluid in lungs. Has nebivolol ever been used in cats as it is cardioselective and less AEs? Nebivolol doesn't have as big HR reduction though.

It appears that nebivolol is being researched for many different possible uses in many lab animal species, but I could not find any information on its use in cats. From the information I could find, most vets have mixed feelings on using atenolol in cats with HCM. There does seem to be a consensus among specialists that it could help in cats with HCM that have Systolic Anterior Motion (SAM) of the mitral valve (seen on echo), but there are no studies showing a positive benefit.
