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.

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.
