Key result
Non-Q wave AMI had higher unadjusted 10-year mortality than Q wave AMI (70.3% vs 60.1%), but this difference was eliminated after adjusting for age and history (RR 1.01; 95% CI 0.82-1.25).

Apparent mortality excess in non-Q wave AMI is explained by age and history; leaves open whether ECG classification adds independent prognostic value.

In patients with suspected ACS, the apparent higher 10-year mortality in non-Q wave AMI compared to Q wave AMI is eliminated after adjusting for age and cardiovascular history.
Johan Herlitz (2001) conducted a cohort in Suspected acute coronary syndrome (n=2,107). Non-Q wave AMI vs. Q wave AMI was evaluated on 10 year mortality (RR 1.01, 95% CI 0.82 to 1.25, p=0.004). Non-Q wave AMI had higher unadjusted 10-year mortality than Q wave AMI (70.3% vs 60.1%), but this difference was eliminated after adjusting for age and history (RR 1.01; 95% CI 0.82-1.25).
