Multiple Arterial Revascularization versus Single in a patients with coronary artery disease

Coronary artery disease occurs when the arteries supplying the heart become narrowed or blocked by fatty deposits. When medication is not enough, bypass surgery (CABG) can reroute blood flow around the blockages using blood vessels from elsewhere in the body. One of the most important choices during bypass surgery is how many arterial grafts to use — veins taken from the leg are commonly used but may not last as long as arteries. This study investigates whether using two or more arterial grafts, rather than just one, leads to better long-term outcomes. Previous research suggests multiple arterial grafts may reduce the risk of death, stroke, heart attack, and the need for repeat procedures over the following years. This trial seeks to confirm that benefit in a prospective study. You may be eligible if you are between 40 and 70 years old and have multivessel coronary artery disease requiring elective primary bypass surgery. People who need additional procedures such as valve surgery or aortic surgery performed at the same time are not eligible for this particular study.
