I took my cat to the cardiologist today and he did NOT hear a murmur...but the ultrasound would check for sure. I decided to do it for my own piece of mind...and once again, it showed NOTHING. He believes her heart is perfectly fine and told me not to worry about this again for at least two years, that she is perfectly healthy. I don't know what to think...can a heart murmur come and go? If it didn't show up on the ultrasound then what were the Vets hearing? I've never spent so much money in 20 minutes LOL...
Once again I thank all of you for your good thoughts and caring!
Since a cardiac ultrasound is the best, definitive way to confirm a murmur and related heart disease, I'd say trust the cardiologist and the results of the test.It's possible, especially with a grade I or II murmur, that your vet just detected a irregular heart beat caused by stress. I do know from speaking with my vet that murmurs can come and go, depending on cause and circumstances. I'd have to do more research into the exact causes. Although our vet heart distinctly heard Peter's murmur on two occasions, there was a third time that she couldn't detect it. This was right after we had been rearended in front of the vet's office and Peter was still very traumatized. His heart was beating so fat, she couldn't detect the murmur.
My advice at this point would be, along with your vet, monitor your cat's condition, especially for any other symptoms of heart disease, and return to the cardiologist for an ultrasound recheck if anything changes.
