Abstract Background Although the patient's characteristics and outcome of acute myocardial infarction (AMI) have been sufficiently investigated and primary percutaneous coronary intervention (PCI) has been recognized as established treatment strategy, those of recent myocardial infarction (RMI) have not been fully evaluated. Purpose The purpose of the present study was to clarify clinical characteristics and in-hospital outcomes of RMI patients from the database of the Tokyo CCU network multicenter registry. Methods In Tokyo CCU network multicenter registry database from 2013 to 2016, 15788 consecutive patients were registered as AMI (within 24 hours from onset) and RMI (within 2–30 days from onset). However 1246 patients were excluded because of inadequate data. And we excluded 66 cases because of out of onset period and 129 cases that strongly suspected of involvement of vasospastic events. Therefore, remaining 14347 patients were categorized to RMI group (n=1853) and AMI group (n=12494), and analyzed. Results Compared with AMI group, average age was older (70.4±12.9 vs 68.0±13.4 years, p
