Abstract：Objective To analyze the standard-reaching rate of time of door-to-balloon (D-to-B) and influencing factors in patients with acute ST-segment elevation myocardial infarction (STEMI) in different approaches to hospital.Methods STEMI patients undergone emergency PCI were chosen from the Department of Cardiology of Central Hospital of Jiading District in Shanghai from Jul. 2012 to Jun. 2016. The patients were divided, according to approaches to hospital and entering catheter room, into routine emergency group (routine group,n=120), 120 call-off group (120 group,n=54), group of pre-hospital startup through referral (referral group, n=26) and group of pre-hospital startup by WeChat platform of chest pain center (WeChat group,n=20). The duration from door to catheter room, D-to-B time, standard-reaching rate of D-to-B time and patient's decision time were observed in 4 groups, and causes of below-standard D-to-B time were analyzed.Results The standard-reaching rate of D-to-B time was 63.18% in all 220 patients, and duration from door to catheter room and D-to-B time were shorter in referral group and WeChat group than those in routine group and 120 group (P<0.01). The standard-reaching rate of D-to-B time was higher in referral group and WeChat group than that in routine group and 120 group (P<0.01). The patient's decision time was lower in referral group and WeChat group than that in routine group and 120 group (P<0.01), and also lower in routine group than that in 120 group (P<0.01). The causes of below-standard D-to-B time mainly included delayed ECG time, delayed consultation time of interventional group, delayed patient's decision time, delayed catheter room preparation time and delayed transfer time, and among them the most common cause was delayed patient's decision time. The causes of below-standard D-to-B time were anatomic variation or operational difficulties during operation in referral group and WeChat group. Conclusion D-to-B time can be shortened and standard-reaching rate of D-to-B time can be improved through implementing pre-hospital startup after setting up WeChat platform of chest pain center.
