Sex as a determinant of prehospital ECG in ST- and non-ST elevation myocardial infarction patients

We read the article by Quinn et al 1 on the effects of prehospital 12-lead ECG (PHECG) on processes of care and mortality with great interest. The authors conclude that when a PHECG was used, patients with ST-elevation myocardial infarction and non-ST elevation myocardial infarction had better survival compared with those without. Interestingly, among the determinants associated with PHECG use, the authors identify female patients to be less likely to have a PHECG than male patients. When the authors discuss possible explanations to the sex differences in PHECG use, they suggest that the predominately male …
