Comparative StudyUtilisation of emergency medical service among Singapore patients presenting with ST-segment elevation myocardial infarction: prevalence and impact on ischaemic time.
Previous studies in Western countries found that the emergency medical service (EMS) was under-used in patients with myocardial infarction. ⋯ Despite the availability of a centralised EMS, 64.7% of patients with STEMI did not contact EMS at presentation. These patients were less likely to receive primary PCI and had a significantly longer symptom-to-balloon time.
