Am I wrong to feel this way?

I had a pretty serious heart attack a year ago ( they run early in my moms side of the family) I am only 42, and otherwise very healthy all my life. never smoked, hardly ever drink alcohol, but because of working 2-3 jobs all the time, I ate way too much fast food. after 8 days in critical care my heart stabilized enough that the doctors took a chance on me and decided to perform open heart surgery, at first they were sure I would just die on the operating table. well its been over a year later, and I have returned to work, and even bodybuilding. people that see me now, make comments like, I wish I could look like you, after almost dying from a heart attack. except for the scar on my chest nobody would ever guess I had one. my question is, since I am still unmarried I am scared that when I do meet a woman, she would be scared off by the fact of my heart attack, I know it is not something that one just blurts out on a first date, but at some point I would have to be honest, as that is my character anyway. I know the most important things are the qualities of a person that matters most, but I have lived long enough to see that it does not always work out the way it should. I have been told quite a bit that I am very good looking, I know I have a very kind and pionate heart, I was self taught writing poetry that can give people tears, I make almost everyone laugh,I am most proud of my ability to just look into a girls eyes ( this hasnt happened too often as I am so picky) and let her know she is loved and cared for without saying a word. but I just cant get past the fear that when I meet a girl that I will have feelings for, as she gets to know me better she might just say to herself, " if I get to know this guy really well and fall for him, why just set myself up for loss, if he just dies. I know that none of us have guarantees of even one more day here on earth, but it might be more likely that I die from this weak heart, than most other guys walking around. so again, am I wrong on this?
