For which condition might "CABG" be performed?

CABG, or Coronary Artery Bypass Grafting, is a surgical procedure primarily performed to improve blood flow to the heart in patients with significant coronary artery disease, which often involves arterial blockage. During this surgery, blood vessels are taken from other parts of the body and grafted to bypass the blocked coronary arteries, thus restoring adequate blood flow to the heart muscle. This procedure is particularly indicated when there are blockages in the coronary arteries that compromise the heart's ability to receive oxygenated blood, potentially leading to heart attacks and other complications.

While chronic heart disease may encompass a range of conditions affecting the heart, CABG specifically targets problems related to blocked arteries. Heart valve replacement is a different type of surgery focused on repairing or replacing faulty heart valves, and lung cancer is unrelated to CABG as it involves the respiratory system, not the cardiovascular system. Therefore, CABG is most relevant for conditions that involve arterial blockages leading to compromised blood flow to the heart.
