I also had postpartum cardiomyopathy. By time they figured out what it was they said I should have never made it to hospital. The only thing that kept me alive is that I didn't lay down. They removed some of the fluid from my chest just so I could breathe. I have to say though, I found a really great doctor that specializes in this. He ran a long line to my heart and fed antibiotics straight to it. A month after getting out of the hospital my ef was back to 50-55. My heart has been normal since and I take no meds for it, that was over 8 years ago. If you are still having problems you might want to see if your doctor will look into it.
