Ouellet GM, et al. - Here, authors recognize factors related to the prehospital delay in a contemporary national cohort of older adults with acute myocardial infarction (AMI). In contrast with younger AMI populations, female sex and diabetes mellitus were not related to the delay in this older cohort, but factors from other domains (nonwhite race, atypical symptoms, and HF) were significantly related to delay. These outcomes can be utilized to customize future public health efforts to encourage early presentation for older adults with AMI.
