Why the study?
Does the electrocardiographic location of a myocardial infarction or the retention/loss of diagnostic Q waves predict long-term mortality in post-MI patients?
Does the electrocardiographic location of a myocardial infarction or the retention/loss of diagnostic Q waves predict long-term mortality in post-MI patients?
Major Q-wave criteria and multiple infarct locations on resting ECG are associated with higher long-term mortality post-MI, whereas the specific single site or loss of Q waves are not.

May aid post-MI risk stratification via ECG; leaves open whether markers improve existing models in prospective cohorts.
Wasserman et al. (1982) studied this question.
