Population
563 patients with acute myocardial infarction and no previous myocardial infarction

Pain duration and analgesics weakly associate with infarct size; observational data leave open their prognostic utility beyond imaging in AMI.
Does the duration of pain and amount of analgesics correlate with estimated infarct size in patients with acute myocardial infarction?
While larger infarcts generally evolve over a longer period with longer pain duration, the severity of pain cannot reliably predict infarct size in individual patients.
Herlitz et al. (2008) studied this question.
