To prepare for coronary bypass surgery, your doctor will give you specific instructions about any activity restrictions and changes in your diet or medications you should follow before surgery. You'll need several pre-surgical tests, often including chest X-rays, blood tests, an electrocardiogram and a coronary angiogram. A coronary angiogram is a special type of X-ray procedure that uses dye to visualize the arteries that feed your heart.
Most people are admitted to the hospital the morning of the surgery. Coronary bypass surgery may also be performed in emergency situations, such as after a heart attack.
Be sure to make arrangements for the weeks following your surgery. It will take about four to six weeks for you to recover to the point where you can resume driving, return to work and perform daily chores.
