abstract
BACKGROUND: Pulmonary embolism (PE) is can present with cardiac arrest. Catheter-based therapies (CBT) provide rapid reperfusion for patients with PE, though their effect on outcomes of patients with PE and cardiac arrest are not well known. AIMS: To evaluate the effect of CBT on outcomes among patients with PE and cardiac arrest. METHODS: This was a retrospective cohort study of patients with PE and cardiac arrest from 2017 to 2020, using the National Readmission Database (NRD). We compared patients who underwent CBT versus no CBT and patients managed with CBT alone versus systemic thrombolysis alone. The primary endpoint was in-hospital death; exploratory outcomes were 90-day death and readmissions. Multivariable logistic and Cox proportional hazards modeling were used. RESULTS: Nine hundred and seventy-three patients were included (111 with CBT). CBT was associated with a lower risk of in-hospital death (36.9% vs. 49.3%, p = 0.015; aOR 0.44, 95% CI 0.23-0.85) with no difference in 90-day readmission (11.3% vs. 18.7%, p = 0.19; aHR 0.63, 95% CI 0.27-1.47). Among the 390 patients with either CBT or systemic thrombolysis alone in-hospital death (34.4% vs. 48.5%, p = 0.023; aOR 0.51, 95% CI 0.21-1.25) and 90-day readmissions (13.3% vs. 11.8%, p = 0.79; aHR 1.04, 95% CI 0.39-2.76) were similar. Ninety-day survival was higher with CBT when compared with no CBT or systemic thrombolytic alone (log-rank p = 0.050 and 0.020, respectively). CONCLUSIONS: Among patients with PE and cardiac arrest, CBT was associated with decreased risk of in-hospital death and 90-day survival compared with no CBT. Further prospective study on utility of CBT in PE and cardiac arrest is needed.
