Abstract:Objective To investigate the factors of hospital delay of acute myocardial infarction with percutaneous coronary intervention. Methods Restropective analysis was applied to 324 STEMI cases with PCI from emergency in Beijing Tiantan Hospital from January 2015 to August 2017. Univariate analysis was used to compare group A (DTB≤90min, 198 cases) and group B (DTB>90 min, 126 cases). Logistic multivariate analysis was adopted to explore related factors. Results Factors of hospital delay were as follows: low level of education (OR = 1.761, 95%CI: 1.071-2.894, P < 0.05), mode of transport to the hospital without EMS (OR = 1.765, 95%CI: 1.087-2.867, P < 0.05), PCI on work-day (OR = 1.936, 95%CI: 1.113-3.369, P < 0.05) and history of digestive diseases (OR = 1.917, 95% CI: 1.085-3.387, P < 0.05). There were some factors that could shorten hospital delay such as initial diagnosis with STEMI (OR = 0.339, 95%CI: 0.207-0.556, P < 0.01) and pre-hospital delay within 120 min (OR = 0.578, 95%CI: 0.353-0.947, P < 0.05). Conclusion It should offer multiform health education to people in order to increase awareness rate and degree of recogniton. Through improving emergency system, enhancing collaboration pre-hospital and in-hospital and promoting more people to use EMS, pre-hospital delay can be shorten. More cultivation on doctors and nurses should be organized to improve ability of triage and prognosis. Optimization of emergency green channel of PCI can promote department cooperation and increase efficiency of DSA to reduce hospital delay.
