I'm 31 yrs old, was diagnosed with perinatal heart failure in feb of 09, with only 25% heart function. I was placed on Coreg 3.125mg 2x a day and 40mg Lasix a day, I stayed at these doses for 6 months and had my second echo at the 4 month mark, my heart returned to normal size, little to no weakness in the upper chamber of my heart and my function was at 50%. I then actually was able to see my cardiologist at the 6 month mark and he told me that he didn't look at the first echo and wanted me to have another so I did and it then showed 60% function and zero weakness, no hypertrophy and he told me that I no longer had heart failure but wanted to lower my lasix to 20mgs a day and up my Coreg to 80mgs a day. I didn't quite understand why they were raising my meds if I was completely better after only 6 months and the Dr. wounldn't answer me with a straight answer and told me that he lumps paitence together and does the same treatments for all of them. And so I didn't fight them, but wasn's willing to up the dose to 80 without an answer so we agreed on 20 for the time being and I actually feel worse on it than I did when I was on the 3.125. My question is 1- if my heart is completely normal after taking the lowest dosage in such a short time why are my meds being raised and 2- I have heard from many different sources that Coreg can over time make your heart lazy and actually cause a weakend heart because it does the work for the heart. I fully admit that I am not a Dr. and dont completely understand, which is why I want answers. I also want to do whatever is best for my health and I believe that I should be fully aware of my condition, so that I can work with the Dr.s and not fight them at every turn. All of this has not sat well with me since it began...PLEASE HELP me to know whether I'm wrong and they are right or whether I have a solid foundation for a second opinion or atleast know if I should confront my current Dr.s...Thank you.
