International audience. BACKGROUND: Pulmonary embolism (PE) represents 2% to 5% of all causes of out-of-hospital cardiac arrest (OHCA) and is associated with extremely unfavorable prognosis. In PE-related OHCA, inconsistent data showed that thrombolysis during cardiopulmonary resuscitation may favor survival.METHODS: This was a retrospective, observational, multicenter study from July 2011 to March 2018. All adults with OHCA, treated by a mobile ICU and with a diagnosis of PE confirmed on hospital admission, were included. The primary end point was 30-day survival in a weighted population.RESULTS: Of the 14,253 patients admitted to hospitals, 328 had a final diagnosis of PE and 246 were included in the analysis. In the group that received thrombolysis during resuscitation (n = 58), 14 (24%) received alteplase, 43 (74%) received tenecteplase, and one (2%) received streptokinase. Thirty-day survival was higher in the thrombolysis group than in the control group (16% vs 6%; P = .005; adjusted log-rank test) but the good neurologic outcome was not significantly different (10% vs 5%; adjusted relative risk, 1.97; 95% CI, 0.70-5.56). Median duration of stay in the ICU was 1 (0-5) day for the thrombolysis group and 1 (0-3) day for the control group (P = .23).CONCLUSIONS: In patients with OHCA with confirmed PE and admitted with recuperation of spontaneous circulation in the hospital, there was significantly higher 30-day survival in those who received thrombolysis during cardiopulmonary resuscitation compared with patients who did not receive thrombolysis.
