What is Bypass Surgery?

An open cardiac procedure called coronary artery bypass grafting (CABG) is performed to treat coronary artery disease (CAD) and restore blood flow to specific parts of the heart. When the arteries that surround your heart are unable to supply adequate blood, this procedure saves your life. Heart muscle cells begin to die when there is insufficient blood flow because of arterial obstructions.

What is the Significance of CABG?

Coronary artery bypass surgery is the most common procedure for the heart in the world. The average age of CABG patients is around 66 years. 

CABG makes a bypass so that blood can go to parts of your heart that require more oxygen. A bypass is similar to your blood taking a detour to avoid a blockage. Surgeons remove a blood vessel from your arm, chest, or leg. They make a new route around the obstruction for the proper blood flow.

If you have numerous blocked arteries, you may require multiple bypasses. Bypasses can be double (2), triple (3), and quadruple (4). Bypass surgery improves your heart function and your quality of living if you are living with severe CAD or if you have experienced a heart attack or are at risk for one. Angina (chest discomfort) and asymptomatic myocardial ischemia are also treated with CABG. There are no symptoms, yet your heart muscle may not be receiving enough blood.

Plaque, an accumulation of fatty substances in arteries, is the root cause of CAD. Your heart's arteries become stiff and constricted due to plaque (atheroma). Blood clots may develop and obstruct certain arteries. If plaque ruptures, parts of your heart experience ischemia (cell death due to lack of oxygen) as a result of those obstructions, ultimately causing a heart attack.
