Brief Summary

The ischemia/reperfusion (I/R) injury of the myocardium initiates a variety and complex sets of inflammatory reactions that may both exaggerate local injury as well as provoke injury of distant organ function . I/R injuries are the main causes of heart failure, morbidity, and mortality after cardiac surgery such as coronary artery bypass graft (CABG surgery) . The reactive oxygen species are believed to be excessively elevated during coronary artery bypass surgery (CABG) due to compromised free radical scavenging mechanism in the myocardium that can make myocardium highly susceptible to oxidative stress and inflammation and result in reperfusion injury . Melatonin and its metabolites protect against inflammation by regulating several inflammatory cytokines. Additionally, melatonin is a free radical scavenger and an antioxidant agent. the current study is designed to investigate the protective effects of melatonin against myocardial I/R injury in patients undergoing coronary artery bypass grafting (CABG) surgery.

Secondary Outcomes (3)

  • interleukin 6 il-6

    24 hours

  • Tumor necrosis factor alpha TNF-α

    24 hours

  • cardiac troponins
