I asked My cardiologist if I have heart failure. He said I have systolic dysfunction of the heart. But on the Internet, it seems they are one and the same. My EF is 20%. I had a massive heart attack on July 24 and a quadruple bypass same day. So is it heart failure? And will it get better? I was put on a life vest and will probably have a defibrillator put in, in a Couple of months. I am on metoprolol, 12.5 mg 2x a day, 40 mg Lasix in am, aspirin in am, 80 mg Lipitor in pm, and Prednisone 10 mg in am.
