Observational Study
Exercise-related resuscitated out-of-hospital cardiac arrest due to presumed myocardial ischemia: Result from coronary angiography and intravascular ultrasound.
Possible causes of exercise-related out-of-hospital cardiac arrest (OHCA) in people with coronary artery disease (CAD) include atherosclerotic plaque rupture (PR) and intra-coronary thrombosis, exercise-induced myocardial ischaemia and other triggers. We investigated whether there are differences in the incidence of PR and/or intra-coronary thrombus and in clinical outcome between 'exercise-related' and 'non-exercise-related' OHCA. ⋯ The incidence of PR and/or thrombosis was lower in the group taking higher levels of exercise, than in the group taking less or no exercise. "Exercise-related" OHCA with CAD has better clinical outcomes than "non-exercise-related" with a greater proportion of witnessed arrests and early return of spontaneous circulation.

Patients suffering out-of-hospital cardiac arrest (OHCA) have a poor prognosis but survival among subgroups differs greatly. Previous studies have shown conflicting results on whether patient comorbidity affects outcome. The aim of this national study was to investigate the effect of comorbidity on outcome after OHCA in Sweden. ⋯ This large national study showed that increasing comorbidity decreased the chance of survival to 30 days in OHCA. This association remained after covariate adjustment.

Multicenter Study
Predicting cardiac arrests in pediatric intensive care units.
Early identification of children at risk for cardiac arrest would allow for skill training associated with improved outcomes and provides a prevention opportunity. ⋯ Patients at high risk of cardiac arrest can be identified with routinely available data after 4 h. The cardiac arrest may occur relatively close to the risk assessment period or days later.

Extracorporeal life support (ECLS) describes the use of blood perfusion devices to provide advanced cardiac or respiratory support. Advances in percutaneous vascular cannula insertion, centrifugal pump technologies, and the miniaturization of extracorporeal devices have simplified ECLS. The intention of this discussion is to review the role of ECLS as a potential rescue method for emergency department (ED) clinicians in critical clinical scenarios and to focus on the prerequisites for managing an ECLS program in an ED setting. ⋯ Emergent ECLS has a role in the ED for selected indications in the face of life-threatening conditions. ECLS provides a bridge to recovery, definitive therapy, intervention or surgery. ECLS program requires an appropriately trained staff (physicians, nurses and ECLS specialists), equipment resources and logistical planning.
