AbstractThe influence of direct calls to specialized Emergency Medical Services in case of suspected myocardial infarction has not been extensively studied. The RICO registry is an exhaustive registry implemented in all six institutions participating in primary care of patients with acute myocardial infarction in one French administrative department (Côte-d'Or). From January 2001 to October 2001, 322 patients were admitted for acute myocardial infarction, among whom only 57 (18%) had directly called emergency medical services after the onset of symptoms. The baseline characteristics of patients who had directly called the emergency services were not different from those of the patients who had not. However, the time from symptom onset to first medical intervention (48 versus 105 minutes, p = 0.02) and from first medical intervention to hospital admission (60 versus 103 minutes, p = 0.02) were markedly shorter in patients who had directly called the emergency medical services. This resulted in a significant increase in the use of reperfusion therapy (70% versus 38%, p = 0.003), including a higher proportion of primary angioplasty (33% versus 20%, p = 0.04). This study documents the beneficial effect of a direct call to the Emergency Medical Services by the patients themselves. Too few patients, however use this opportunity and actions should be taken for informing the lay public of the benefits of this medical service.
