Coronary artery bypass surgery is performed to treat a blockage or narrowing of one or more of the coronary arteries, thus restoring the blood supply to the heart muscle.
Symptoms of coronary artery disease may include, but are not limited to, the following:
Shortness of breath
Unfortunately, there may be no symptoms of early coronary artery disease, yet the disease will continue to progress until sufficient artery blockage exists to cause symptoms and problems.
If the blood supply to the heart muscle continues to decrease as a result of increasing obstruction of a coronary artery, a myocardial infarction, or heart attack, may occur. If the blood flow cannot be restored to the particular area of the heart muscle affected, the tissue dies.
There may be other reasons for your physician to recommend coronary artery bypass surgery.
