Impact of Wechat-based prehospital data transmission on reperfusion times in ST-elevation myocardial infarction: a prospective observational study

Objectives Early diagnosis of acute ST-segment Elevation Myocardial Infarction (STEMI) is important for the treatment of patients. A Class I evidence demonstrates that every 30-minute delay in PCI is linked to a 7.5% relative increase in 1-year mortality1 "WeChat" is a convenient communication tool that enables the transmission of patient information ‒ including basic details, condition assessments, and relevant laboratory results ‒ to the receiving hospital via WeChat-based transmission. Simultaneously, patients are rapidly transported to the hospital by ambulance for treatment. Thus, the hospital can receive patient information before their arrival, thereby significantly reducing diagnosis and treatment time. This integrated model is collectively referred to as WeChat-based transmission. Therefore, the early activation of WeChat-based emergency medical services transmission plays a critical role in improving patient prognosis. The present study sought to investigate the use of WeChat-based transmission in patients with acute STEMI.Methods 409 eligible STEMI patients (May 2022-November 2024) were grouped by WeChat-based transmission use: 96 in the observation group and 313 in the control group. Baseline data, medical history, and key times (S-to-FMC, d-to-B, TIT) were compared. Factors influencing WeChat-based transmission use were analyzed via SPSS 22.0 (p Results 96 (23.4%) patients in the WeChat-based transmission group and 313 (76.6%) patients in the N-WeChat group were enrolled. S‑to‑FMC time was associated with lower median values in the WeChat‑based transmission group (median 75 vs. 120 minutes, p Conclusion WeChat-based transmission was associated with shorter S-to-FMC, d-to-B, and TIT times during patient transfer for PCI. However, it is not fully used for transporting chest pain patients in and around Shijiazhuang City. Therefore, strengthening WeChat-based transmission function in public education of pre-hospital rescue remains the focus of our future work.
