Has anyone seen heart murmurs improve in their cats?

I have had several cats over the years with various grades of heart murmurs.  Three of mine currently have murmurs, 2 of them having had Doppler ultrasounds in the past.  My cats get regular checkups, annually or semiannually depending on age and issues.  All 3 of them have recently had heart murmurs that improved.  One has a murmur that is barely detectable if at all.  I don't get it.  Are they transient?

Eventually they will understand,
Replied the glorious cat
For I will whisper into their hearts
That I am always with them
I just am....forever and ever and ever.

I don't know the answer but did the murmur show up on one ultrasound and not the next?  I know on occasion a vet has been unable to detect the murmur on exam.   

Is a Doppler ultrasound a special kind (I need to read up on medical stuff) or is that just what heart ultrasounds are called?

One of my cats developed a significant murmur and then had dental surgery and cleaning to clear up some tooth problems.  The murmur got a lot better after the dental.  They use a number classification system  I-VI, higher numbers being worse.  Her murmur went down a couple of numbers.

I've also noticed that some vets can hear the murmurs better than others.  But it it was the same vet doing the exam, I'd be willing to bet that the murmurs have actually gotten better.

I asked the vet cardiologist (whom I have seen a lot of in the past 1 1/2 years) if changes in weight could affect how the murmur was heard or actually change the murmur itself.  She said that she did not have a definitive answer, but that both were certainly possible.

I am glad to hear that the cats got better!

Hi JustMe,

I personally have seen heart murmurs improve in cats.  I have a kitty Rufus, who had a serious Gallop rhythm and it has diminished in intensity.

My Gizmo was diagnosed at the age of 5 with left ventricular hypertrophy and a murmur.  That was 5 years ago.  Gizmo's murmur is gone, did not even show up on the echo that was done on October 2.

I give Rufus and Gizmo 30mg. every day of Co-Enzyme Q-10.  

My vets are now recommending to clients whose cats have these issues, to use the Q-10.  It's funny, because every now and then they'll get a client with a cat and I'll get the phone call asking....."What's the dose you use?"

In answer to your question of transiency, if there is too much pressure appied to the sternum, the murmur will be more pronounced.  This happens quite frequently with new vets who are examining kittens.  They will immediately hear a murmur, but if you tell them to loosen up a bit on their hold of the kitten, it will be lessened or inaudible.

I have one manufacturer that I use for the Q-10.  If you're interested, please let me know.

I had a cat with a heart murmur and while it didn't improve, it also never worsened or became a negative factor in her health. She lived to seventeen.
