"A few weeks ago I felt a terrible pain in my chest, but it eventually went away so I decided not to go to the doctor. You think my heart is ok?"
Well, if it's not, it's too late for us to do anything about it now! If you think you're having a heart attack, seek medical attention while it's happening, not a few weeks later, after the damage has been done and the best we can do is an EKG to see if anything shows up. This woman probably didn't have a heart attack-- my best guess from her more detailed description is that she ate something that didn't sit well-- but still, it's not terribly useful to tell me about things that happened weeks ago and went away.
