Ask the doctors: Can surgery cause a heart attack?

Print This Page
Q.A friend with heart disease was doing fine until he underwent an operation for colon cancer. He got through the first few days without any problems, but then had a heart attack on the fourth day and nearly died. Why would he have had a heart attack after an operation? I need to have surgery and am wondering how dangerous it will be.

Fortunately, that risk is quite low—1% to 2%—for most people and most operations. Colon surgery is, however, a fairly major operation, and your friend's history of heart disease increased his risk for cardiac complications. That said, he needed to have the surgery. The best that can be done in such cases is to do everything possible to minimize the risk, watch closely for problems, and tackle them quickly if they arise. There is always some risk with surgery, but the risk is low and can be made even lower by carefully watching for problems before, during, and after the operation.
