I actually had to look this one up. I wasn't aware of any heart problems related to CMTD. I have read about some conduction problems (electrical system of the heart) with CMTD but not related to heart function of cardiomyopathies. There are case reports of CMTD and cardiomyopathies, but there is not a clear consensus about wheterh CMTD is the driver (the cause) or if it is coincidence. The article I pasted the link to below suggests that there is not a definite relationship.
For that reason, if I saw a patient in clinic with similar problems, I would treat them as I would any other cardiomyopathy: beta blocker, ACEI or ARB, diuretic if necessary.
I hope this helps. Thanks for posting.
