Pat after my first heart attack I felt very tired that one was an A fib issue both chambers stopped. My second heart attack I had 2 stents put in and I was awake for that procedure. For me as soon as the doctor opened that stent and removed the device that opens it up i felt like a million bucks. The new blood flow was an amazing thing it was like night and day I was always dog tired before the procedure and after I felt so good and had the energy of someone half my age. I sure hope you take it easy Brother, do what your doctor says and listen to the admiral, my prayers are with you.
