Highlight
- Longer estimated hospital arrival times are independently associated with increased in-hospital mortality in patients with cardiogenic shock (CS).
- This association persists at 1-year follow-up, indicating long-term survival disadvantages related to delayed access to advanced care.
- Mortality risk progressively rises as travel time exceeds 10, 30, and 60 minutes compared to arrival within 10 minutes.
- Data support the implementation of regional shock networks and enhanced prehospital triage systems to improve timely access to definitive care.
