Hi Dave, congratulations on a successful surgery! Just like what you said, walking really helps in the post op recovery process. I had my apical myectomy 13 months ago and by now I can exercise for over an hour (moderate aerobic exercise) 3-5 days a week. The only thing I would add to what you have been doing is, consider doing cardiac rehab at a hospital or rehab center close to you. Since I am an international patient (I am from Taipei, Taiwan), I waited for 7 weeks post op to take a 17 hour flight home (even though I didn’t have to wait for that long to travel on an plane safely). While staying in Rochester, I went to Mayo’s cardiac rehab center almost everyday for 5-6 weeks. I started my first rehab session around 12 days after surgery. The nurses and physiologists at Mayo’s rehab center were really nice and helpful (always cheerful and encouraging), and spending an hour there everyday really helped get myself back in the swing of things. I literally started out by only being able to do 10-15 min of exercise (treadmill and bike), but every time I went, I made incremental improvement in terms of the time and intensity of my exercise program. By the time I was leaving Rochester, I was able to do 50 min of mild aerobic exercise. Aside from doing cardiac rehab, everyday I would walk for at least 20-40 min and do a bit of household chores. Doing those range motions also helped quite a bit in terms of reducing the tightness on my chest and around the incision line. Besides all this, I thought getting enough sleep and eating balanced meals were equally important. I waited til maybe 7 months post surgery (until my sternum was stable) to really have exertion on my upper body. At times I felt there was always something weird on my upper body, but eventually everything healed and became ‘normal’. We just have to trust that our bodies have magical powers that make everything go back to its normal state. I wish you a speedy recovery!
