Outcome of out-of-hospital cardiac arrest after fibrinolysis with reteplase in comparison to the return of spontaneous circulation after cardiac arrest score in a geographic region without emergency coronary intervention.

Coronary occlusion and pulmonary embolism are responsible for the majority of cases of out-of-hospital cardiac arrest (OHCA). Despite previous favourable results of pre-hospital fibrinolysis in cases of OHCA, the benefit could not be confirmed in a large controlled study using the fibrinolytic tenecteplase. For reteplase (r-PA), there are hardly any data regarding pre-hospital fibrinolysis during ongoing resuscitation.
