Early and late ventricular arrhythmias complicating ST-segment elevation myocardial infarction.

Background: Ventricular arrhythmias can be life-threatening complications of ST-segment elevation myocardial infarction (STEMI).

Aims: To describe the incidence, predictors and in-hospital impact of early ventricular arrhythmia (EVA, occurring
Methods: Data from 13,523 patients enrolled in a prospective registry were analysed.

Pharmacoinvasive Strategy Versus Primary Percutaneous Coronary Intervention for ST-Segment Elevation Myocardial Infarction in Patients ≥70 Years of Age.

The benefit-risk ratio of a pharmacoinvasive strategy (PI) in patients ≥70 years of age with ST-segment elevation myocardial infarction (STEMI) remains uncertain resulting in its limited use in this population. This study compared efficacy and safety of PI with primary percutaneous coronary intervention (pPCI). Data from 2,841 patients (mean age: 78.

Predicting the development of in-hospital cardiogenic shock in patients with ST-segment elevation myocardial infarction treated by primary percutaneous coronary intervention: the ORBI risk score.

Aims: To derive and validate a readily useable risk score to identify patients at high-risk of in-hospital ST-segment elevation myocardial infarction (STEMI)-related cardiogenic shock (CS).

Methods And Results: In all, 6838 patients without CS on admission and treated by primary percutaneous coronary intervention (pPCI), included in the Observatoire Régional Breton sur l'Infarctus (ORBI), served as a derivation cohort, and 2208 patients included in the obseRvatoire des Infarctus de Côte-d'Or (RICO) constituted the external validation cohort. Stepwise multivariable logistic regression was used to build the score.

Immediate complete revascularization in patients with ST-segment elevation myocardial infarction and multivessel disease treated by primary percutaneous coronary intervention: Insights from the ORBI registry.

Background: Recent studies demonstrated the superiority of complete revascularization (CR) in patients treated by primary percutaneous coronary intervention (pPCI) in ST-elevation myocardial infarction (STEMI).

Aim: To evaluate whether immediate CR improves in-hospital outcomes in patients with STEMI with multivessel disease.

Methods: Data from a prospective multicentre registry including 9365 patients with STEMI were analysed.

Efficacy and safety of prehospital administration of unfractionated heparin, enoxaparin or bivalirudin in patients undergoing primary percutaneous coronary intervention for ST-segment elevation myocardial infarction: Insights from the ORBI registry.

Background: Despite numerous studies in recent years, the best anticoagulant option for primary percutaneous coronary intervention (PCI) remains a matter of debate.

Aims: To compare in-hospital outcomes after prehospital administration of low-dose unfractionated heparin (UFH)±glycoprotein IIb/IIIa inhibitors (GPIs), enoxaparin±GPIs, or bivalirudin in patients undergoing primary PCI for ST-segment elevation myocardial infarction (STEMI).

Methods: A total of 1720 patients (median age 62.

Incidence, timing, predictors and impact of acute heart failure complicating ST-segment elevation myocardial infarction in patients treated by primary percutaneous coronary intervention.

Background: Acute heart failure (AHF) complicating ST-segment elevation myocardial infarction (STEMI) is recognized as an ominous complication. Previous studies mostly reported outcomes of heterogeneous, non-contemporary population. Moreover, few studies assessed the prognosis of AHF according to its timing.

High-degree atrioventricular block complicating ST segment elevation myocardial infarction in the contemporary era.

Background: High-degree atrioventricular block (HAVB) is a common complication of ST segment elevation myocardial infarction (STEMI). HAVB in STEMI is historically considered as a marker of worse outcome but overall data about HAVB in the contemporary era of mechanical reperfusion and potent antiplatelet therapies are scarce.

Aim: Analysing incidence, clinical correlates and impact on inhospital outcomes of HAVB in a large prospective registry (Observatoire Régional Breton sur l'Infarctus, ORBI) of modern management of STEMI with a special focus on potential differences between patients with HAVB on admission and those who developed HAVB during hospitalisation.

Safety of prasugrel in real-world patients with ST-segment elevation myocardial infarction: 1-year results from a prospective observational study (Bleeding and Myocardial Infarction Study).

Background: Antiplatelet therapies, including prasugrel, are a cornerstone in the treatment of ST-segment elevation myocardial infarction (STEMI), but are associated with a bleeding risk. This risk has been evaluated in randomized trials, but few data on real-world patients are available.

Aim: To evaluate prasugrel safety in real-world patients with STEMI.

Gender differences in presentation, management and inhospital outcome in patients with ST-segment elevation myocardial infarction: data from 5000 patients included in the ORBI prospective French regional registry.

Background: Gender differences in presentation, management and outcome in patients with ST-segment elevation myocardial infarction (STEMI) have been reported.

Aim: To determine whether female gender is associated with higher inhospital mortality.

Methods: Data from ORBI, a regional STEMI registry of 5 years' standing, were analysed.

Efficacy of pre-hospital use of glycoprotein IIb/IIIa inhibitors in ST-segment elevation myocardial infarction before mechanical reperfusion in a rapid-transfer network (from the Acute Myocardial Infarction Registry of Brittany).

Previous studies investigating prehospital use of glycoprotein IIb/IIIa inhibitors (GPIs) in patients with ST-segment elevation myocardial infarction reached conflicting conclusions. The benefit of this strategy in addition to in-ambulance loading of dual-antiplatelet therapy remains controversial. The aim of this study was to analyze data from a prospective registry of patients with ST-segment elevation myocardial infarctions admitted <24 hours after symptom onset (July 2006 to May 2012).

Door-to-balloon delays before primary angioplasty in the Regional Acute Myocardial Infarction Registry of Brittany. An analysis of the Observatoire Régional Breton sur l'Infarctus du myocarde (ORBI).

Background: Minimizing delays to coronary reperfusion is critical in the management of acute myocardial infarction (AMI).

Aims: To determine delays in in-hospital management and factors associated with delays of over 45min.

Methods: We analysed data from the Observatoire Régional Breton sur l'Infarctus, a registry of AMI patients admitted within 24h of symptom onset (July 2007 to December 2008) to an interventional cardiology centre in Brittany.
