Key result
Among AMI patients surviving the first 30 days, out-of-hospital cardiac arrest was associated with similar long-term risk compared to STEMI (aHR 1.15; 95% CI 0.82-1.60) and NSTEMI.

OHCA in AMI signals high 30-day mortality risk requiring intensive early care; leaves open whether targeted interventions can improve short-term outcomes.

Does out-of-hospital cardiac arrest affect short- and long-term survival in patients admitted with acute myocardial infarction compared to those without cardiac arrest?
Hazard Ratio: 1.15 (95% CI 0.82–1.6)
Although short-term mortality is high, AMI patients with OHCA who survive the first 30 days have similar long-term survival to AMI patients without OHCA.
Kvakkestad et al. (2017) conducted a cohort in Acute myocardial infarction (AMI) (n=9,829). Out-of-hospital cardiac arrest (OHCA) vs. AMI without OHCA (STEMI and NSTEMI) was evaluated on Long-term risk among patients surviving the first 30 days (OHCA vs STEMI) (HR 1.15, 95% CI 0.82-1.60). Among AMI patients surviving the first 30 days, out-of-hospital cardiac arrest was associated with similar long-term risk compared to STEMI (aHR 1.15; 95% CI 0.82-1.60) and NSTEMI.
