The purpose of a coronary artery bypass graft (CABG) is to improve blood flow to the heart. This surgical procedure involves taking a blood vessel from another part of the body and using it to create a detour around blocked or narrowed coronary arteries. By bypassing these areas of obstruction, the graft allows oxygen-rich blood to reach the heart muscle more effectively.

This increased blood flow can alleviate symptoms like chest pain (angina) and reduces the risk of heart attacks by ensuring that the heart receives the necessary oxygen and nutrients. It is a crucial intervention for patients with significant coronary artery disease, where the heart's blood supply is compromised due to plaque buildup.

While other procedures may address different heart concerns, such as removing tissue or treating valve defects, the specific goal of CABG is centered on restoring adequate blood flow to the heart itself.
