I Had A Widowmaker Heart Attack On 10/6/15. I Have

I had a widowmaker heart attack on 10/6/15. I have almost completed three months of cardio rehab. On Dec. 31, I needed a 2 pint transfusion due to anemia. What are the chances that I will ever fully recover to 100% healthy? Prior to the Widowmaker, I thought I was in great health with minimal body fat, regular exercise, decent (but not perfect) diet, so the heart attack was a shock to me and my wife.
