Not only men. I was a seemingly healthy, 47-year old woman when I had a heart attack and went into cardiac arrest (twice, in the ambulance - thank God for the EMTs who defibrillated me).
I had NO known heart problems, NO family history (they all get cancer), didn't smoke, wasn't overweight, and exercised regularly. Turns out I have a congenitally deformed left anterior descending artery that either went into spasm, or had a blood clot (the angiogram wasn't able to determine the definite cause).
That is young for a woman, glad you made it OK. Genetics can play a big role in what we get and what we don’t seem to get..You like my son #2 had a birth deformaty that was inside and not outside the body. He has only 2 coronary arteries, but according to tests, is small arteries are growing.
