Agree with what you've heard from others. The big message is STAY POSITIVE. My open heart surgery (MV repair, one bypass) was in late September 2011. By Thanksgiving, I was ready for cardio rehab, which meant I had myself walking 30 minutes. Finished rehab in Feb or March. Exercising at the same level, six days a week since. My meds get tweaked now and then but I'm still taking several. Life is GOOD.
