Coronary Artery Bypass is a surgical procedure used to improve blood flow to the heart. It involves taking a healthy blood vessel from another part of the body, such as the leg or chest, and using it to create a new pathway for blood to bypass blocked or narrowed arteries. This helps to relieve symptoms like chest pain and reduces the risk of heart attacks. During the surgery, doctors make an incision in the chest to access the heart. After the bypass is created, the heart can receive more oxygen-rich blood, allowing it to function better. This procedure is often recommended for patients with severe coronary artery disease.
