BACKGROUND: Thrombolytic treatment has been shown to accelerate resolution of major pulmonary embolism and lead to a rapid improvement of right-side hemodynamics. However, the association between these favorable effects and the clinical outcome of patients who have no severe hemodynamic compromise at presentation remains unknown. METHODS AND RESULTS: The present multicenter registry included 719 consecutive patients with major pulmonary embolism according to clinical, echocardiographic, scintigraphic, and cardiac catheterization criteria. Symptom onset was acute (<48 hours) in 63% of patients. All patients were hemodynamically stable (ie, without evidence of cardiogenic shock) at presentation. Primary thrombolytic treatment (within 24 hours of diagnosis) was given to 169 patients (23.5%), whereas the remaining 550 patients were initially treated with heparin alone. Overall 30-day mortality was significantly lower in the patients who received thrombolytic agents (4.7 versus 11.1%, P=.016). Clinical factors associated with a higher death rate were syncope (P=.012), arterial hypotension (P=.021), history of congestive heart failure (P=.013), and chronic pulmonary disease (P=.032). However, only primary thrombolysis was found by multivariate analysis to be an independent predictor of survival (odds ratio for in-hospital death, 0.46; 95% confidence interval, 0.21 to 1.00). Patients who underwent early thrombolytic treatment had a reduced rate of recurrent pulmonary embolism (7.7 versus 18.7%, P<.001) but also a higher frequency of major bleeding episodes (21.9% versus 7.8%, P<.001). Cerebral bleeding occurred in 2 patients in each treatment group, and 1 patient in each group died of a bleeding complication. CONCLUSIONS: The results of our study suggest that thrombolysis may favorably affect the clinical outcome of hemodynamically stable patients with major pulmonary embolism.
