Decision to deploy coronary reperfusion is not affected by the volume of ST-segment elevation myocardial infarction patients managed by prehospital emergency medical teams.

Objective: Mortality in patients with ST-segment elevation myocardial infarction (STEMI) has been associated with the volume of activity of percutaneous coronary intervention (PCI) facilities. This observational study investigated whether the coronary reperfusion-decision rate is associated with the volume of activity in a prehospital emergency setting.

Methods: Prospectively collected data for the period 2003-2013 were extracted from a regional registry of all STEMI patients handled by eight dispatch centers (SAMUs) in and around Paris [41 mobile ICU (MICUs)].

Incidence, Mortality, and Outcome-Predictors of Sudden Cardiac Arrest Complicating Myocardial Infarction Prior to Hospital Admission.

Background: Mortality of ST-segment-elevation myocardial infarction (STEMI) decreased drastically, mainly through reduction in inhospital mortality. Prehospital sudden cardiac arrest (SCA) became one of the most feared complications. We assessed the incidence, outcome, and prognosis' predictors of prehospital SCA occurring after emergency medical services (EMS) arrival.

Time-Course Reduction in Patient Exposure to Radiation From Coronary Interventional Procedures: The Greater Paris Area Percutaneous Coronary Intervention Registry.

Background: The frequency of complex percutaneous coronary interventions (PCIs) has increased in the last few years, with a growing concern on the radiation dose received by the patients. Multicenter data from large unselected populations on patients' radiation doses during coronary angiography (CA) and PCI and temporal trends are lacking. This study sought to evaluate the temporal trends in patients' exposure to radiation from CA and PCI.

Identifying Patients at Risk for Prehospital Sudden Cardiac Arrest at the Early Phase of Myocardial Infarction: The e-MUST Study (Evaluation en Médecine d'Urgence des Stratégies Thérapeutiques des infarctus du myocarde).

Background: In-hospital mortality of ST-segment-elevation myocardial infarction (STEMI) has decreased drastically. In contrast, prehospital mortality from sudden cardiac arrest (SCA) remains high and difficult to reduce. Identification of the patients with STEMI at higher risk for prehospital SCA could facilitate rapid triage and intervention in the field.

Longer pre-hospital delays and higher mortality in women with STEMI: the e-MUST Registry.

Aims: The mortality rate in patients with STEMI is higher in women than in men. This higher mortality rate is partly accounted for by certain known characteristics inherent in the female population (age, diabetes). Using data from the e-MUST registry on STEMI patients in the Greater Paris area, we assessed the differences between men and women treated with reperfusion strategies.

Outcomes of primary percutaneous coronary interventions in nonagenarians with acute myocardial infarction.

Background: Few data are available on primary percutaneous coronary intervention (pPCI) in nonagenarians. In a large prospective registry on pPCI for STEMI we compared the demographics, procedural and in-hospital outcomes between nonagenarians (age ≥ 90 years) and patients aged < 90 years.

Methods And Results: We included 26,157 consecutive patients with pPCI in the Greater Paris Area region between 2003 and 2011.

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.
