Anyones problem been fixed?

Has anyone had cardiac problem like heart disease, arrythiams, etc(anthing heart) and it has been fixed so you are able to go for a run, play basketball, workout, do intense physical activity and not be in pain?

I'm fortunate to be free of heart problems, but my husband has not been. A few years ago his internist had him do a stress test because he has type II diabetes and is at higher risk for heart disease. He'd had no symptoms whatsoever.

Long story short, two weeks later he was in surgery having three stints placed into highly occluded coronary arteries. Without the surgery, he would likely have had a massive heart attack in short course and might not have still been here with us six years later.
