I had a quadruple cardiac bypass procedure performed on 8/8/2011. I had no symptoms whatsoever prior to my procedure; however, a treadmill EKG revealed 1-3 mm depressions of the ST segment during exercise at approximately 8 minutes. I felt totally fine during the treadmill test, even though the EKG indicated otherwise. A resultant angiogram revealed left main disease, which then resulted in my quadruple bypass procedure. After 4 weeks, I am already walking 2 miles in the AM and 2 miles in the PM without any difficulties. I played tournament competitive men's softball in Florida monthly prior to my procedure and I look forward to playing softball once again. When I played, I was typically the best player on my team and I could still run fast, throw hard and hit home runs. My question is as follows: How long does it take for the sternum to heal post surgery and when could I begin playing softball once again without any fear of opening my incision or adversely affecting my sternum. I would also hit 100-200 softballs weekly prior to my surgery. even though I am 52-years-old, I am still young at heart. No pun intended.
