What condition is directly treated by performing a CABG?

Coronary Artery Bypass Grafting (CABG) is a surgical procedure specifically designed to treat blocked coronary arteries. These arteries supply blood to the heart muscle, and when they become narrowed or blocked due to atherosclerosis or other cardiovascular issues, the heart may not receive adequate oxygen and nutrients. CABG creates a new pathway for blood to flow to the heart muscle by using a graft, which is typically a portion of a vein or artery taken from another part of the body.

The goal of CABG is to restore blood flow, relieve chest pain (angina), and reduce the risk of heart attacks, thereby significantly improving the patient's quality of life and overall heart function. It directly addresses the underlying issue of blocked coronary arteries, making it the primary condition treated by this surgical intervention.

Other conditions listed, such as heart valve stenosis, aortic aneurysm, and chronic heart failure, may require different types of surgical or medical treatments and are not the primary focus of CABG.
