Increased Serum Bilirubin Level is Related to Good Collateral Development in Patients with Chronic Total Coronary Occlusion

Abstract

This study suggests that higher bilirubin levels within relatively normal ranges were related with favorable coronary collateral growth in patients with CTO. SBL may be responsible for the difference in coronary collateral vessel development among different patients with coronary artery disease. The anti-inflammatory and anti-oxidant properties of bilirubin may mediate this effect.
