Observational Study
Impact of right ventricular dysfunction on mortality in adults with cardiac arrest undergoing coronary angiogram.
We sought to identify the impact of echocardiographic right ventricular (RV) systolic dysfunction on mortality in adults with cardiac arrest (CA). ⋯ In this observational contemporary study, RV dysfunction was independently associated with higher mortality in adults with CA undergoing coronary angiogram. RV dysfunction may be useful for risk stratification and management in this high-mortality population.

To evaluate volume-outcome relationship in paediatric out-of-hospital cardiac arrest (OHCA). ⋯ There may be a relationship between institutional case volume and survival outcomes in paediatric OHCA.

Cardiac arrest related to accidental hypothermia may occur at temperatures below 32 °C. Our goal was to describe the clinical characteristics and outcomes of patients who suffered from witnessed hypothermic cardiac arrest (CA) and assess the occurrence of hypothermic CA as a function of patient body temperature. ⋯ CA that is solely caused by hypothermia did not occurs for patients with a body temperature >30 °C. Our findings provide valuable new information that can be incorporated into the international clinical management guidelines of accidental hypothermia.

Ion shift index as a promising prognostic indicator in adult patients resuscitated from cardiac arrest.
Several studies reported that disturbances in cellular ion homeostasis occur following ischaemia, the magnitude of which was proportional to illness severity. The changes in serum electrolyte levels following ischaemia were minor compared with the changes in ion concentrations in the extracellular fluid. To amplify the serum electrolyte changes, we devised a new index (ion shift index), which could be calculated using commonly measured serum electrolyte levels, and explored its prognostic value in adult cardiac arrest patients. ⋯ Our results suggest that the ion shift index can be helpful in the early prognostication of adult cardiac arrest patients.
