Dilated Cardiomyopathy

This is my first time posting on Reddit and I hope I’m in the right place!

I’m currently writing a character with Dilated Cardiomyopathy. I did as much research as I could using actual helpful websites and I understand the basics of it. At least to an extent. I suppose I’m just scared of being stereotypical..

I just have a few questions,

How would DCM affect someone’s day to day life?
What are the most common symptoms of DCM?
Do DCM patients have Cardiac seizures/convulsive syncope? If so how would a doctor deal with that?

Those are some of my DCM questions.. My older sister tried to explain it to me (She has a bachelor in biology) but it made me more confused.

Another question is, What would it look like for a long-term hospital patient?

I just really need help writing for this character, this is my first time writing for a disease that could kill someone🥲 if that makes sense. And I want to be as accurate as I can!
