Increased fibrinolysis as a specific marker of poor outcome after cardiac arrest

Recent data suggest that early increased fibrinolysis may be associated with unfavorable prognosis in cardiac arrest. The current study aimed to assess whether there is an optimal fibrinolysis cut-off value as determined by thrombelastometry at hospital admission to predict poor outcome in a cohort of adult patients with out-of-hospital cardiac arrest.  Patients with out-of-hospital cardiac arrest of presumed cardiac origin, subjected to targeted temperature management, who had achieved return of spontaneous circulation at admission were analysed.
Fibrinolysis was assessed by thrombelastometry at the bedside immediately after hospital admission and is given as maximum lysis (%). The outcome measure was the optimal cut-off for maximum lysis at hospital admission to predict poor outcome (a composite of cerebral performance category 3-5 or death) at day 30, assessed by receiver-operating characteristic curve analysis.  Seventy-eight patients (61% male, median 59 years) were included in the study from March 2014 to March 2017. The maximum lysis cut-off on admission predicting poor 30-day outcome with 100% specificity (95%CI 90-100%) was ≥20%.
