title: Ask the doctors. I suffered a heart attack a few years ago, had an emergency angioplasty, and fortunately survived. I've been feeling great. But when I saw my cardiologist recently, he told me that I needed an implantable defibrillator because my heart muscle had been weakened by the heart attack. Do you think I need this?
