Coronary artery bypass grafting is also known as bypass surgery, coronary artery bypass surgery and heart bypass surgery. It is a medical procedure that restores blood flow to your heart muscle. In the procedure, blood flow is diverted around a section of a blocked artery in your heart. It is the only effective treatment option for heart disease.
Coronary artery bypass grafting helps improve symptoms such as chest pain and shortness of breath. In some cases, coronary bypass surgery may improve your heart function and lower your risk of dying of heart disease.
Coronary artery bypass grafting is an option for you in the following cases.
There could be severe chest pain, which is most likely because of the narrowing of several arteries that supply your heart muscle, leaving the muscle short of blood during even light exercise or at rest. Angioplasty and stenting can help in the situation, although bypass surgery is the only option for some of the cases.
You doctor will advise coronary artery bypass grafting when there is more than one diseased coronary artery. Another case your doctor will advise bypass surgery is when heart's main pumping chamber, the left ventricle, isn't functioning well. If your left main coronary artery is severely narrowed or blocked, you may need bypass surgery.
In case there is an artery blockage for which angioplasty isn't the treatment option, angioplasty or stent placement that hasn't been successful or the artery has narrowed again (restenosis) after treatment, bypass surgery may be needed.
Coronary artery bypass grafting may also be done in emergency situations such as a heart attack or if other treatments are not responding to other treatments.
Coronary artery bypass grafting may not treat the underlying heart disease that caused blockages in the first place. It is usually the case of atherosclerosis or coronary artery disease.
When you have bypass surgery, lifestyle changes are still a necessary part of treatment after surgery. Other than lifestyle changes, your doctor will prescribe medications that lower your blood cholesterol, lower the risk of developing a blood clot and helps heart perform its function.
