Abstract Objective: To investigate the current status of acute ST-segment elevation myocardial infarction (STEMI) in different age groups after the establishment of a region chest pain center. Method: A total of 275 patients with acute STEMI were enrolled in Anning First People's Hospital from January 2017 to December 2020. According to the age, the subjects were divided into the young group, the middle-aged group, and the elderly group. The general information, ways of coming to the hospital, symptom onset-to-first medical contact (S2FMC) time, treatment plan, double bypass, door-to-balloon (D2B) time, angiography results, reasons for reperfusion delay, prisoners' blood vessels and blood flow information were collected. Statistical methods were used to analyze and describe the current situation of reperfusion treatment at different age groups and its influencing factors in chest pain centers in counties. Result: (1) STEMI patients were most commonly elderly and male patients. (2) Patients came to the hospital by themselves, network hospital transfer, 120 call and in-hospital onset, and the difference in the mode of arrival between different groups was not statistically significant (P>0.05). (3) The differences in double bypass, treatment plan, offender vessel and blood flow information between different groups were not statistically significant (P>0.05). (4) All enrolled The shortest visit time after onset was 13 min and the longest was 1 956 min. 235 patients were seen within 12 h. More patients in the youth group had S2FMC time >12 h than in the middle-aged and elderly group had S2FMC. (5) The median D2B of STEMI patients was 82.10 min, and the main reasons for delayed reperfusion included: family non-arrival, long informed consent time, intraoperative complications delay, delayed preoperative complications and delayed physician decision making, and the differences in the distribution of D2B time among different groups of patients were not statistically significant (P>0.05). Conclusion: The duration of S2FMC is significantly longer in young STEMI patients than in the middle and old age groups, suggesting that patients in the old age group were better educated about myocardial diseases. The next step is not only to actively strengthen community education, but also to expand the scope of education and promote it among the young population.
