Heart surgery is still thought of as scary and life-threatening, but it is not really so. It is in fact a safe procedure. Few people know that, bypass surgery in routine cases has a risk of only 1-2%, which is similar or even less than many general surgical operations on the other part of the body.
So, rather than live with the threat of Coronary Artery Disease (CAD) getting worse, it is better to get a bypass operation done because the chances of the operation being successful are 98-99%. More important, the benefits after the operation are far more than the risk of living with the constant threat of a heart attack every day.
Bypass removes the dangerous risk of a sudden heart attack.
It is undoubtedly better to get a CABG done before a heart attack, because a heart attack may permanently damage a part of the heart muscle.
