Popis: Objective The aim of this study was to compare the prognosis and time reduction between helicopter emergency medical services (HEMS) with a physician and ground emergency medical services (GEMS) in acute myocardial infarction (AMI) cases. Methods This is a registry-based study of the Japan Helicopter Emergency Medical Service Registry from April 1, 2015, to March 31, 2018. Results A total of 605 cases of AMI were registered in the HEMS group and 794 cases in the GEMS group. In the cases of non–cardiopulmonary arrest (CPA), the prognosis between HEMS and GEMS did not differ significantly. Regarding the road distance, for ranges of 20 to 40 km and > 40 km, the times from the call to the angiography room were significantly shorter with HEMS than GEMS (median 91 vs. 97 minutes, P = .036 and 101 vs. 132 minutes, P = .002, respectively). In cases of CPA, HEMS had a higher rate of return of spontaneous circulation than GEMS (55.3% vs. 36.8%, P = .038), but HEMS had a lower prognosis than GEMS (22.9% vs. 38.9%, P = .036). Conclusion The present study suggested that HEMS had an advantage in reducing the time to angiography in AMI cases of non-CPA. In cases of CPA, HEMS increased the return of spontaneous circulation without improving the prognosis.
