Hi Areti,
In cats with CHF of any cause I would now use furosemide and clopidogrel only. Possibly spironolactone too as we haven’t any good evidence for or against this currently. There was a recent paper by King et al (2019) that showed no benefit of ACE inhibitors either in CHF or pre-clinically.
In pre-clinical HCM I don’t use anything. In severe HOCM I do use atenolol still.
Hope you have a lovely weekend,
Liz
