Coronary bypass surgery is a surgical technique that reroutes the flow of blood near a section of a blocked or partially blocked an artery in the heart. By creating a new pathway to the heart, coronary bypass surgery enhances blood flow to the heart muscle. During coronary bypass surgery, a healthy blood vessel is taken from your leg, arm or chest and connected to the other arteries in your heart so that blood gets diverted from the diseased or blocked area. After coronary bypass surgery, symptoms, such as chest pain and shortness of breath due to poor blood flow to the heart, generally improve. For some people, coronary bypass surgery may boost up the heart functions and reduces the risk of dying of heart disease. Coronary bypass surgery is an option if –
You have severe chest pain due to the narrowing of several arteries that supply blood to the heart muscle.
When your left main coronary artery is severely narrowed or blocked because this artery supplies most of the blood to the left ventricle.
When you have an artery blockage for which angioplasty has been done and still the artery is narrowing.
Coronary bypass surgery may also be performed in emergency situations, such as a heart attack if the doctor sees that the patient is not responding to the other treatments. Even if you have coronary bypass surgery, lifestyle changes are still an essential part of treatment after the surgery. Medications are uniformly followed after the coronary bypass surgery to lower the blood cholesterol, reduce the risk of developing a blood clot and help the heart function as well.
