THE KEY OBJECTIVE IN CORONARY ARTERY BYPASS GRAFT IS TO

• A. Extend life
• B. Improve blood flow and oxygen supply to the heart ✓
• C. Improve blood flow and oxygen supply to the lungs
• D. Relieve pain

The key objective in coronary artery bypass graft (CABG) is to improve blood flow and oxygen supply to the heart. This surgical procedure is commonly performed to treat coronary artery disease, where there are blockages or narrowing in the coronary arteries that supply blood to the heart muscle. By creating new pathways for blood to flow around the blocked or narrowed arteries, CABG helps improve blood flow and oxygen supply to the heart muscle, thereby reducing symptoms like chest pain (angina) and improving overall heart function.

During CABG surgery, a healthy blood vessel is taken from another part of the body, such as the chest or leg, and grafted onto the coronary artery beyond the blockage. This allows blood to bypass the blocked area and reach the heart muscle, restoring proper blood flow and oxygen delivery to the heart.

Benefits of CABG

1. Extend Life: By improving blood flow and oxygen supply to the heart, CABG can help extend the life expectancy of patients with severe coronary artery disease. It reduces the risk of heart attacks and other complications associated with inadequate blood supply to the heart.
2. Improve Heart Function: Enhanced blood flow and oxygen delivery to the heart following CABG can improve overall heart function, leading to better cardiac performance and reduced symptoms of heart disease.
3. Relieve Symptoms: CABG can alleviate symptoms such as chest pain, shortness of breath, and fatigue that are often experienced by individuals with significant coronary artery blockages.

In conclusion, while relieving pain is a potential benefit of CABG, the primary objective of this surgical procedure is to improve blood flow and oxygen supply to the heart, thereby enhancing cardiac function and potentially extending life expectancy for patients with coronary artery disease.
