摘要：OBJECTIVE To describe the duration of the pre-hospital delay time and identify factors associated with prolonged pre-hospital delay in patients with acute myocardial infarction (AMI) in China. METHODS Data were collected from November 2014 to December 2019 as part of the Improving Care for Cardiovascular Dis-ease in China-Acute Coronary Syndrome (CCC-ACS) project. A total of 33,386 patients with AMI admitted to the index hospitals were included in this study. Two-level logistic regression was conducted to explore the factors associated with the pre-hospital delay and the associations between different pre-hospital delay and in-hospital outcomes. RESULTS Of the 33,386 patients with AMI, 70.7％ of patients arrived at hospital ≥ 2 h after symptom onset. Old age, female, ru-ral medical insurance, symptom onset at early dawn, and non-use of an ambulance predicted a prolonged pre-hospital delay (all P < 0.05). Hypertension and heart failure at admission were only significant in predicting a longer delay in patients with ST-seg-ment elevation myocardial infarction (STEMI) (all P < 0.05). A pre-hospital delay of ≥ 2 h was associated with an increased risk of mortality [odds ratio (OR) = 1.36, 95％ CI: 1.09–1.69, P = 0.006] and major adverse cardiovascular events (OR = 1.22, 95％ CI: 1.02–1.47, P = 0.033) in patients with STEMI compared with a pre-hospital delay of < 2 h. CONCLUSIONS Prolonged pre-hospital delay is associated with adverse in-hospital outcomes in patients with STEMI in China. Our study identifies that patient characteristics, symptom onset time, and type of transportation are associated with pre-hospital delay time, and provides focuses for quality improvement.
