The effect of melatonin on endothelial dysfunction in patient undergoing coronary artery bypass grafting surgery.

Background: In this study, we investigated the effect of melatonin administration on four markers of endothelial cell function including intercellular adhesion molecule (ICAM), vascular cell adhesion molecule (VCAM), C-reactive protein (CRP), and nitric oxide (NO) on patients with three vessels coronary disease.

Materials And Methods: This double-blind, randomized, controlled trial study was conducted on 39 patients (32 men and 7 women) with three vessels coronary disease. The case group included 20 patients who received 10 mg oral melatonin 1 h before sleeping for 1 month.
