Open-heart surgery is done to:

• Open-heart surgery may be done to perform a CABG. A coronary artery bypass graft may be necessary for people with coronary heart disease.
• repair or replace heart valves, which allow blood to travel through the heart
• repair damaged or abnormal areas of the heart
• implant medical devices that help the heart beat properly
• replace a damaged heart with a donated heart

Risks for open-heart surgery include:

• chest wound infection (more common in patients with obesity or diabetes, or those who’ve had a CABG before)
• heart attack or stroke
• irregular heartbeat
• lung or kidney failure
• chest pain and low fever
• memory loss or “fuzziness”
• blood clot
• blood loss
• breathing difficulty
• pneumonia

surgery does not prevent artery blockage from happening again. You can help improve your heart health by:

• eating a healthy diet
• cutting back on foods high in salt, fat, and sugar
• leading a more active lifestyle
• not smoking
• controlling high blood pressure and high cholesterol
