Margolis G, et al. - Researchers retrospectively assessed the trends of prehospital delays in 2,203 consecutive patients hospitalized for acute ST-elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI) between January 2008 and December 2016. Using patients’ medical records, they obtained information on the delay in time from symptom onset to presentation at hospital. Regarding prehospital delay periods for patients undergoing primary PCI, significant variations were reported over the 9-year study period. The independent association of older age, diabetes, first STEMI, and female sex with a prehospital delay of more than 2 hours was demonstrated in multivariate logistic regression model. Educating at-risk populations about seeking early medical assistance needs should be prioritized.
