As an EMT, I too found this rather disturbing. Throughout the article, prehospital interventions were repeatedly not acknowledged. From the reference to "ambulance drivers" that you mentioned to things as subtle as saying that the clock starts when the patient rolls into the ER rather than when the ambulance arrives on scene, the article completely misses (or does not fully acknowledge) a hugely important factor in improving outcomes for STEMI: the prehospital care involved.
