I love this site!!! YOU got some excellent comments here. The BB's limit your heart rate chemcially, so the effort it takes to get you to 130-150 is HUGE! Also, the idea of trying other exercize elements as riding is getting to you, an excellent idea! Wish I had thought of that when I had this feeling about my running a few years back!
My totally unscientific guess on recovery, based on my friends over at cardiac athletes, is: the younger the patient is at surgery time, the more likely you can get back close to pre op fitness levels....the older, the longer, and maybe never. Also, those who take up running, biking, etc. only after a heart event don't have their history to compare against, so they don't have these issues of recovery.
