Key result
Late arrival (>8 hours) in patients with suspected AMI was associated with higher 1-year mortality compared to early arrival (≤2 hours) in both confirmed (32.6% vs 26.0%) and ruled-out AMI.

Delayed arrival in suspected AMI signals higher 1-year mortality even if ruled out; leaves open whether earlier presentation improves outcomes.

Does delay time between symptom onset and hospital arrival impact 1-year mortality in patients with suspected AMI?
Absolute Event Rate: 32.6% vs 26%
Patients with suspected AMI who arrive late to the hospital have a higher 1-year mortality rate, regardless of whether AMI is ultimately confirmed.
Karlson et al. (2008) conducted a cohort in Suspected acute myocardial infarction (AMI) (n=2,944). Delay time between symptom onset and hospital arrival vs. Early arrivers (≤2 h) was evaluated on 1-year mortality rate. Late arrival (>8 hours) in patients with suspected AMI was associated with higher 1-year mortality compared to early arrival (≤2 hours) in both confirmed (32.6% vs 26.0%) and ruled-out AMI.
