Background:Characteristics and treatment outcomes of acute myocardial infarction (AMI) patients have been studied; however, those of recent myocardial infarction (RMI) patients remain unclear. This study aimed to clarify characteristics, treatment strategy, and in-hospital outcomes of RMI patients in the Tokyo CCU network database.Methods and Results:In total, 1,853 RMI and 12,494 AMI patients from the Tokyo CCU network database during 2013–2016 were compared. Both RMI and AMI were redefined by onset times of 2–28 days and ≤24 h, respectively. The RMI group had a higher average age (70.4±12.9 vs. 68.0±13.4 years, P
