Impact of Geographic Access on Mortality in Cardiogenic Shock: Insights from a Nationwide Korean Cohort

Highlight

• Longer hospital arrival times correlate with higher in-hospital and 1-year mortality rates in cardiogenic shock (CS) patients.
• Patients with arrival times over 60 minutes had an adjusted 51% increase in odds of in-hospital death compared to those arriving under 10 minutes.
• These mortality trends persisted after adjusting for confounders and across de novo and acute-on-chronic CS subtypes.
• Findings underscore the need for strategic regional shock networks and early triage to enhance timely access to advanced care.
