Randy, during my heart cath, I, too, learned that I had no other heart problems. My surgeon said almost the same thing as did Bob's. The healthier you are at the time of surgery the greater likelihood that your recovery will be excellent. Not having additional heart problems that must be addressed during surgery should mean that the process is less complicated and that usually translates into a shorter time on the heart lung machine which many people feel is better for a good outcome. As Julian, pointed out, though, how healthy you are at the time of surgery doesn't necessarily predict your experience during the first week or so after surgery; still, your long term recovery should be excellent.
Being in good health at the time of surgery does not change the basic recovery schedule. It takes about three weeks for your incisions to heal both inside and outside. That's the time you will feel weakest and need to be careful to get plenty of rest and avoid stressing yourself. Even during that time, however, you need to be walking several times a day; just don't push yourself. That said, I found I could walk half a mile three or four times a day by the end of two weeks without exhausting myself. By the end of the third week, I felt OK walking a mile at a time without a problem. Just keep in mind that one person's experience does not translate into your own.
After that first three weeks, Randy, you must still be careful not to stress your chest muscles in order to allow your sternum to heal completely which will take another nine weeks. By the end of those first three months, you will be able to safely begin a full exercise program including upper body work. It can be tempting to push beyond your limits during those three months. Consider, however, that during that time you are preparing your body for living a good life.
