The medical world has achieved a significant breakthrough through coronary artery bypass graft surgery, professionally known as CABG ("cabbage"). Every year, hundreds of individuals with serious coronary heart disease benefit from this life-saving surgery. Plaque buildup makes cardiac arteries narrow or block totally, which prevents heart muscle cells from getting sufficient oxygen and blood supply. The surgical procedure uses alternate blood vessels to create detours around hazardous cardiac regions. The article presents a detailed description of how remarkable treatment improves heart disease symptoms while boosting blood circulation in all body parts. Patients with their families will know better about surgery progress and resultant dramatic life quality improvement through these understanding concepts. 1. Creating New Pathways Around Blockages The idea behind CABG surgery is really straightforward: provide a detour if a route is closed. Surgeons remove healthy blood arteries from another area of the body, usually the arm, leg, or chest, during the treatment. After that, these vessels—known as grafts—are carefully affixed to form new blood vessels. The aorta, the heart's major artery, is sewed to one end of the graft, and the coronary artery beyond the obstruction is connected to the other end. The formerly deprived cardiac muscle may now get oxygen-rich blood freely thanks to this new channel. 2. Immediate Relief of Oxygen Deprivation For heart muscle cells to work correctly, oxygen must be present at all times. Angina, a type of chest discomfort, is brought on by oxygen deprivation in these cells when coronary arteries constrict or get …
