Impact of snowfall on emergency medical system and mortality in patients with acute coronary syndrome.

ABSTRACT: Acute coronary syndrome (ACS) requires rapid transportation by the emergency medical system (EMS). In snowy areas, traffic conditions may delay EMS transport times and increase mortality rate of ACS. However, there is a paucity of systemic data showing how snowfall affects the EMS and mortality in patients with ACS. This study aimed to investigate the impact of snowfall on the EMS transport times and in-hospital death in patients with ACS. We examined 2387 consecutive ACS patients who were transported via EMS to hospitals participating in the Sapporo City ACS network between April 2013 and April 2023. The patients were divided into two groups based on their arrival on either a snowy day (n = 612, 26%) or a non-snowy day (n = 1775, 74%), as determined by historical weather records from the
