I have dilated cardiomyopathy. My cardiologist also was the one who really encouraged the surgery. So far, we haven't seen any crazy change in my ejection fractions, but we will see in June at my next echo. By then I would have been down more than 120 lbs for more than a year, so he is eager to see if there will have been any changes to my heart function.
Having said that, I have had to reduce my BP meds quite a bit, so that's good. But, we are trying not to reduce them too much since they help with my DCM.
