My mom's been having trouble with her breathing for a bit now, and we recently got an echo test done. They said her heart is bigger than normal and kinda weak, functioning at about 25% of what it should be. She's 50, has high blood pressure, and is a bit diabetic. I'm really worried about her. Do you think this is something we can fix? How serious is it? Should I be really alarmed?

Yes it is alarming since the heart functioning is only 25.., u may require an echo for further management and a cardiac opinion.
