Cardiomyopathy and WLS

I have a condition called cardiomyopathy, a disease of the heart muscle and in my case an enlarged/weakened heart.  I did not see the heart disease forum and wanted to know if anyone at all has Cardiomyopathy and has had wls or could not have it due to the condition and if you are now able to drink lots of fluids and if it helped improve your injection fraction. 

Got it.  Had the surg 2 years ago and it has really helped.  I have lost over 70 pounds, my blood pressure med, and my heart med.  Had to drop the latest cholesterol med because of side effects.  So all I am taking is my thyroid med and vitamens!  Sure doing better than before!
