Melatonin has attenuated myocardial ischemia reperfusion injury in experimental studies. We hypothesized that the administration of melatonin during acute myocardial reperfusion improves myocardial salvage index in patients with ST-elevation myocardial infarction. Patients (n = 48) were randomized in a 1:1 ratio to intracoronary and intravenous melatonin (total 50 mg) or placebo. The myocardial salvage index assessed by cardiac magnetic resonance imaging at day 4 (± 1 day) after primary percutaneous coronary intervention was similar in the melatonin group (n = 22) at 55.3% (95% CI 47.0-63.6) and the placebo group (n = 19) at 61.5% (95% CI 57.5-65.5), p = 0.21. The levels of high-sensitive troponin T, creatinine kinase myocardial band, and oxidative biomarkers (advanced oxidation protein products, malondialdehyde, myeloperoxidase) were similar in the groups. The frequency of clinical events at 90 days did not differ between the groups. In conclusion, melatonin did not improve the myocardial salvage index after primary percutaneous coronary intervention in patients with ST elevation myocardial infarction compared with placebo.
