I have heard of other problems it can cause a person to have with their heart. I was taken off it when I had a heart attack. I then started seeing a law suit over it, but when I read the paperwork and symptoms ( Mostly CHF) I knew it did not cause my SCAD MI. I am a member of a group of women in a study at Mayo dealing with SCAD and I am the only one ever on darvocet so I don't believe it was my cause.
