In fact, about 60 percent of those with heart disease don't know they have the condition until they have a heart attack - or worse, says Thomas Donohue, M.D., section chief of cardiology at the Hospital of Saint Raphael."About 40 percent of heart disease sufferers have a heart attack," adds Donohue, who's board-certified in internal medicine and cardiovascular disease.

"You can't look at it like it's the pipes in your house," Donohue explains."Your arteries are living things.They can renarrow."

"The mammary artery is really preferred; it's a wonderful conduit," explains Donohue, adding that veins degenerate more quickly because they cannot withstand the relatively intense pressure of blood coursing in and out of the heart.Since most people have at least three (and usually four or five) bypasses done at one time, doctors must sometimes resort to using veins.
Barring complications, most bypass patients go home within four to five days of the operation."This is an incredibly oft-performed procedure, and for people in their 60s, the mortality rate is less than 1 percent" says Donohue.

"It's very frustrating," agrees Thomas Donohue, M.D., section chief of cardiology at the Hospital of Saint Raphael.

One myth about heart patients is that they aren't supposed to move, that they should be resting all the time, explains Donohue.But just the opposite is true — under a doctor's supervision, of course."In my experience, when folks move, when they begin to exercise, they have remarkable improvement," he says.This doesn't mean people should begin lifting weights or training for a marathon.But taking a 20-minute walk, swimming a lap or two at the YMCA or bicycling around your neighborhood can do a world of good.
"Anything's better than nothing," Donohue says."I don't think people should be satisfied with just anything.But doing anything is better than lying on the couch, eating Doritos and watching TV."Exercise is unbelievable," he concludes.
