Prehospital STEMI data transmission speeds reperfusion
Impact of Wechat-based prehospital data transmission on reperfusion times in ST-elevation myocardial infarction: a prospective observational study
Clinics · 2026-09-30 · Added 3 October 2026
In 409 Chinese STEMI patients, prehospital WeChat transmission of patient data to the PCI centre shortened symptom-to-first-medical-contact (75 vs 120 minutes), door-to-balloon (50 vs 67 minutes) and total ischaemic time (121.5 vs 150 minutes).
- Study type
- Cohort
- Design
- Prospective observational cohort
- Participants
- 409 STEMI patients (96 with WeChat transmission, 313 without)
- Main finding
- Median symptom-to-first-medical-contact 75 vs 120 min, door-to-balloon 50 vs 67 min, total ischaemic time 121.5 vs 150 min (all p < 0.05)
- Caveat
- Non-randomised grouping — patients selected for WeChat transmission may have differed systematically; single-region Chinese system
- Bottom line
- Supports current practice
Why it matters in Australia (Medium relevance). Pre-alerting and transmitting ECGs to cath labs is standard practice here, so this supports what Australian crews already do — the app itself is incidental and the observational design can't separate the effect from selection bias.
Learning goal
Understand how early prehospital notification of STEMI to PCI centres shortens reperfusion times in my practice.

12-lead transmission lags equipment availability
A national survey of 588 of Japan's 723 fire departments found 92.7% had at least partial 12-lead ECG recording capability but only 9.7% routinely recorded and transmitted, with chest pain/ACS protocols — not equipment — the strongest driver of transmission uptake.
