Participants	Population: acute non‐ST segment elevation myocardial infarction, successful PCI with stent Age, mean (SD) each arm: not reported (18‐ to 80 years) Sex, % male in each arm: not reported Number of diseased vessels: not reported Number of stunned hyperkinetic, etc segments: not reported Time from symptom onset to initial treatment: < 48 hours Statistically significant baseline imbalances between the groups?: not reported
