The one real positive about my experience, besides not dying, was Morphine. It'd be real easy to get used to that stuff. Add fresh oxygen and I'm not sure I cared if I was going to die.
All kidding aside. When they are wheeling you in for an Angiogram and telling you if you need stents they'll do up to two and any more than that they transfer you for bypass or open heart surgery it's a real sobering experience. I was lucky in that I only had 25% blockage which the Cardiologist say's can be rectified with diet and exercise. The nurse told me I was one of the few lucky ones who get to walk out of critical care.
