Hi. I am 66 years old. This year a day before my birthday, I had a heart attack. A stent was put in one artery (the widowmaker which was 100% clogged), and a few days later I underwent quadruple bypass surgery. My advice is if your dr is a cardiologist that you trust, and you are relatively healthy otherwise, you should proceed. Recovery was tough at first but I recommend that you do cardio rehab as soon thereafter as possible, and exercise as much as you can after the rehab is over. My EF factor was originally 35% but by exercising daily I just had a mugatest which showed that my EF factor is now 50%. Of course, as with any surgery, you should get a second opinion just to be sure. Best of luck, ttrimb1e.
