Few months ago, my sister died of peripartum cardiomyopathy. After 5 months of giving birth, I noticed her tummy was still big like of a 4 months pregnant. Her face and feet swelled too. After a series of test, she was diagnosed of this sickness. Those years that she suffered from that sickness, complications came after another, kidney failure etc.

I am having a hard time coping up with her lost just as I don't have any idea about this kind of heart ailment. I will appreciate much if you can help me understand about this?
