Heart bypass surgery is typically an open-heart surgery , which means that the surgeon cuts the chest open to reach the heart. On-pump surgery involves using a heart-lung machine that circulates blood and breathes for the body. The machine allows doctors to stop the heart, which makes the operation easier.

Risks and potential complications vary for each person. A doctor can help decide which treatment is the best option for each person. Before heart bypass surgery, people should:. A person undergoing a planned heart bypass operation will have an opportunity to discuss the procedure with their doctor before the operation. The care team will explain the surgery, set up arrival times, and help complete paperwork.

Many people may undergo tests before the surgery including an electrocardiogram EKG , chest X-ray, and blood tests. The IV will allow fluids and medicines to enter the body as needed.

A member of the healthcare team might also shave the areas where a surgeon will make their incisions. Immediately before the surgery, the doctors provide medicine that causes a deep sleep until after the operation.

Surgeons perform hundreds of thousands of heart bypass operations each year and many of those who have the surgery get relief from their symptoms without needing long-term medication.

It is normal to experience soreness and night sweats, and there is likely to be some fluid in the lungs, so people should expect a good bit of coughing.
