The delivery of primary percutaneous coronary intervention (pPCI) through heart attack networks has completely changed the short- and long-term prognosis of patients with ST-elevation acute myocardial infarction (STEMI) . Patients presenting with STEMI represent up to 40 % of acute coronary syndrome hospital admissions representing a significant burden on hospital bed capacity. In such times of economic pressures, there is a move towards reducing hospital length of stay which represents one of the principle drivers of healthcare costs. Furthermore in the context of the ongoing COVID-19 pandemic and it's significant impact on hospital admissions, healthcare systems are increasingly looking towards early discharge both for elective admissions and those occurring in the more acute setting as a means of increasing capacity.
