Effects of Melatonin on Reperfusion Injury

October 4, 2017 updated by: Chen Wei Ren, MD, Chinese PLA General Hospital

Effects of Melatonin on Reperfusion Injury in Patients With ST-segment Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention

Acute myocardial infarction is a major cause of mortality and morbidity. Primary percutaneous coronary intervention (pPCI) is currently the most effective treatment strategy in acute myocardial infarction. However, a sizable number of patients fail to restore optimal myocardial reperfusion, mostly because of the 'no-reflow' phenomenon. Melatonin is the chief indoleamine produced by the pineal gland, and a well-known antioxidant and free radical scavenger. Several studies have shown that melatonin protects against ischemia/reperfusion injury (IRI). In our previous study, melatonin markedly reduced infarcted area, improved cardiac function and reduced lactate dehydrogenase release in rats. The investigators planned to research the cardioprotective effects of intravenous melatonin administered prior to reperfusion and continued after restoration of coronary blood flow in patients with ST segment elevation myocardial infarction undergoing pPCI.

Design Details

  • Primary Purpose: TREATMENT
  • Allocation: RANDOMIZED
  • Interventional Model: PARALLEL
  • Masking: SINGLE

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
EXPERIMENTAL: Melatonin group
Patients will receive a total intravenous melatonin dose of 11.61 mg (aproximately 166 μg/kg).

Patients will receive a total intravenous melatonin (Helsinn Chemical Co, Biasca, Switzerland) dose of 11.61 mg (aproximately 166 μg/kg). The dose will be distributed in a volume of 500 ml of an isotonic and sterile solution of 100 μM melatonin during 150 min with a drip rate of 4.2 ml/min.

The temporal distribution of perfusion will be: 30 min previous to percutaneous revascularization and remainder doses in a subsequent 120 min (1 h during the angioplasty +60 min post-intervention).

Other Names:
  • melatonin
PLACEBO_COMPARATOR: Control group
Patients will receive the same dose of placebo.
The temporal distribution of perfusion will be: 30 min previous to percutaneous revascularization and remainder doses in a subsequent 120 min (1 h during the angioplasty +60 min post-intervention).
Other Names:
  • Placebo
