My cat has mild feline HCM. What can I do for his heart without meds?

Pet's info: Cat | Mixed Breed | Male | neutered | 8 years and 1 month old | 15 lbs

I have a cat with feline HCM. In April he was diagnosed via echocardiogram. Heart thickening was very slight. The cardiologist didn't want to give meds because the disease is too mild. Is there anything that I can do? Vitamins, supplements, changes that will possibly help?

I have attached a link below that provides some general information on HCM. Your cardiologist may have given you much of this and i am sure has ruled out things like high thyroid (hyperthyroidism) and high blood pressure. The most important things are to rule out other diseases that can cause thickening, monitor at home for any changes, and follow up with your cardiologist to see if the disease is progressing. For cats that are diagnosed when asymptomatic (such as evaluation for a heart murmur) the disease may or may not advance. Many cats can live a long life if the disease does not advance. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach! www2.vet.cornell.edu/departments-centers-and-institutes/cornell-feline-health-center/health-information/feline-health-topics/hypertrophic-cardiomyopathy
