Prehospital identification of acute ST-elevation myocardial infarction (STEMI) and activation of the cardiac catheterization laboratory (CCL) can improve first medical contact-to-balloon (FMC2B) times. We describe regional collaborative network for STEMI based on WeChat to provide seamless transfer bypassing emergency department for primary percutaneous coronary intervention (PCI). The purpose of this study was to examine the effect of 12-lead electrocardiogram (ECG) transmission via WeChat on FMC2B times.
A retrospective, consecutive cohort study was conducted on 94 STEMI patients who were initially seen in community or non-PCI-capable hospital, transferred for primary PCI at Luhe hospital, a rural hospital, which serves an area of 1.35 million inhabitants, from July 1, 2015 to March 31, 2016. Two groups were divided according to the different pathways to the CCL: WeChat group had 36 patients with a prehospital 12-lead electrocardiogram transmission via WeChat, taken by emergency medical system (EMS) and transferred directly to CCL of Luhe hospital, control group had 58 patients who transferred by EMS to emergency department before CCL arrival. The primary outcome was median FMC2B times and the secondary outcome was door to balloon (D2B) times.
In the WeChat group versus the control group, the median symptom onset-to-first-medical contact time was similar (118 [96-155] vs. 112 [90-142] min, p>0.05), but the median FMC2B and D2B were significantly shorter (90 [70-129] vs.120[90-160]min, p < 0.001; 32[20-60] vs.65 [46-103]min, p < 0.001,respectively). There is no differences in time to reperfusion once the CCL was reached.
Prehospital activation of the CCL via WeChat resulted in earlier reperfusion of STEMI patients.
