Advantages to Coronary Artery Bypass Surgery Come to Light

Most heart-attack-causing lesions occur in the upper one-third of an artery. CABG bypasses these lesions and much of the remaining artery by attaching the bypass graft far downstream in an area less vulnerable to disease. As the disease continues to evolve in the artery, the bypass graft continues delivering oxygenated blood to the heart muscle nourished by the artery. This is how CABG prevents future heart attacks from occurring.
