In this narrative review, we contrast an \"ideal\" STEMI pathway with the pathways commonly observed in routine practice for patients treated with primary PCI, and we contextualize deviations from best practice from patient, clinician, health service, and societal perspectives. From the patient's perspective, the priority is rapid symptom recognition and seeking care; however, delays are frequent, particularly in individuals with mild, atypical, or non-classical presentations, prolonging total ischemic time and increasing myocardial injury. Clinicians aim to diagnose STEMI promptly and initiate evidence-based therapy and reperfusion without delay, yet diagnostic uncertainty and competing differentials can contribute to missed or late diagnoses. Health systems seek to provide timely, efficient, and cost-effective emergency revascularization, but performance is influenced by pre-hospital logistics, triage, catheterization laboratory availability, and inter-hospital transfer processes. At the societal level, STEMI imposes substantial mortality, morbidity, and economic burden through premature death and disability.
