Background and purpose It remains unknown whether patients with out-of-hospital cardiac arrest (OHCA) experience prodromal symptoms. We aimed to investigate symptoms reported by patients with OHCA contacting emergency medical services (EMS) within 24 hours prior to arrest. Methods We linked OHCAs occurring from 2016 through 2018 to corresponding emergency calls occurring within 24 hours prior to arrest (defined as “pre-arrest calls”). These calls were included and evenly split and evaluated by authors. Results Among 4071 patients with OHCA, 481 patients (11.8%) had pre-arrest calls (59.9% males, median age 74 years) with a total of 539 calls. Figure 1 shows the reported symptoms across calls. The most commonly reported symptoms were breathing problems (59.4%), confusion (23.0%), unconsciousness (20.2%), chest pain (19.5%) and paleness (19.1%). The most common co-occurring symptom pairs were breathing problems in combination with paleness (14.5%), confusion (14.1%), unconsciousness (13.5%), sweating (13.0%) and chest pain (11.9%), respectively. An urgent response was dispatched in 68.7% of calls containing breathing problems compared to 83.0% of calls containing chest pain. Conclusion Among patients with OHCA, 11.8% had a call to EMS within 24 hours prior to arrest and breathing problems was the most commonly reported symptom occurring in 59.4% of calls.
