Impact of off-hour admission on the MACEs of patients with acute myocardial infarction

Abstract

Background: In China, on more than 100 weekends or holidays, only on-duty cardiologists are available during admissions. This study aimed to analyze the impact of admission time on major adverse cardiovascular events (MACEs) in patients with acute myocardial infarction (AMI).
