Don, I have been down that road with the triple by-pass that was caused by a major coronary that resulted in no heart damage, thank goodness.
Don't rush anything. Take care of yourself and the Serenity Prayer works wonders. It goes like this:
"May God grant me the serenity to accept the things I cannot change, the strength to change the things I can, and the wisdom to know the difference."
I carry it in my billfold. So far, so good. At 65 and 10 years past the open heart, all is well.
I hope yours goes good and the recover time is great.
