Bloos SM, Kaur K, Lang K, et al. - Given that predominantly older adults are affected by ST-segment elevation myocardial infarction (STEMI) and diagnosis among younger patients may be challenging because of lower incidence, researchers sought to examine if emergent percutaneous coronary intervention (PCI) for STEMI is delayed among patients ≤ 50 years old relative to patients aged > 50 years. In this 3-year 10-center retrospective cohort study, they included 576 emergency department (ED) STEMI patients ≥ 18 years of age treated with emergent PCI. Of these patients, 100 were ≤ 50 years old and 476 were > 50 years old. Findings revealed that patients ≤ 50 years old and those > 50 years old did not differ statistically significantly in door-to-balloon (D2B) times. The younger population was disproportionately composed of nonwhite patients and those who smoke. Higher odds of D2B times > 90 min were reported for very young and very old.
