[Evolution since 2002 of the management of patients with ST elevated acute coronary syndrome (STEMI) in Île-de-France. E-MUST survey].

INTRODUCTION

ST-segment-elevation acute myocardial infarction (STEMI) is a therapeutic emergency. Early reperfusion is the key to successful reperfusion. Guidelines recommend organizing regional networks. In France, this starts with a call to a medical dispatch center, the SAMU-centre 15. The aim of this study was to evaluate regional STEMI management using data collected from 2002 to 2010.

METHODS

Observational, prospective, multicenter survey. STEMI patient with chest pain lasting for less than 24hours managed by 40 mobile emergency and resuscitation service (SMUR) and 8 emergency medical system (SAMU) from the Greater Paris Area (Île-de-France) were analyzed. Demographic data, cardiovascular risk factors, infarction location, decision of reperfusion and delays were collected. The rate of coronary reperfusion was chosen as the primary endpoint.

RESULTS

Eleven thousand five hundred and eighty-eight patients enrolled from 2002 to 2010 were analyzed. Median age was 59.9 (51.0 to 72.9) years; 9080 (78.5%) were men. The number of patients included decreased from 1376 in 2002 to 1119 in 2010. Reperfusion was achieved by fibrinolysis in 2644 (23%) cases and primary angioplasty in 7999 (69%) cases. The rate of decision of coronary reperfusion significantly increased from 86.7% in 2002 to 94.8% in 2010 (P<0.0001). Interaction between the increasing decision of reperfusion and all factors studied (demographics, cardiovascular risk factors, infarct location and delays) was significant only for family history of coronary artery disease (P=0.03). In-hospital mortality was 2.8% (321 cases).

CONCLUSION

The number of patients with STEMI managed by the SAMU declined slightly over the past decade. The rate of decision of reperfusion progressively increased up to 95%. Entrance into the network by the SAMU-centre 15 is a guarantee of a wide and early access to the coronary reperfusion.
