Advice plz

Ok so yesterday I went to see my cardiologist and she told me that since I am 8weeks and 5 days I should really think about having an abortion because my heart muscle is weak. There is a 50% chance of my heart getting weaker after the second trimester but there is also an 8% chance of death to me after or during labor and there is a 25% chance of early delivery and the baby not surviving or having the same issues I have with my heart. I just need advice to know what u moms would do. I have a 4 yr old girl. I'm 24 and have had a heart attack and stroke.
