“…The two primary approaches for optimizing ACS patient outcomes are to reduce treatment delay and to minimize total ischemic time, defined as time of symptom onset to reperfusion of culprit arteries (Hicks et al, 2015; O’Gara et al, 2013). ACS symptoms trigger patient care seeking behaviors and inform providers’ choice of diagnostic testing; yet symptoms are often ambiguous (Rosenfeld et al, 2015). If symptoms are neither identified nor recognized, patients may be at risk for increased prehospital delay, delayed diagnosis, and increased mortality and morbidity (Doggen et al, 2016; Fanaroff, Rymer, Goldstein, Simel, & Newby, 2015; Menees et al, 2013; O’Gara et al, 2013; Wu, Moser, Riegel, McKinley, & Doering, 2011).…”
