Background There is a paucity of data on the long-term clinical outcomes according to the severity of pulmonary embolism (PE) at initial diagnosis. Methods The COMMAND VTE Registry is a multicenter registry enrolling 3027 consecutive patients with acute symptomatic venous thromboembolism (VTE). After excluding 1312 patients without PE, the current study population consisted of 1715 patients with PE, who were divided into 3 groups according to the clinical severity; massive PE, sub-massive PE and low-risk PE. Results There were 179 patients (10%) with massive PE, 742 patients (43%) with sub-massive PE, and 794 patients (46%) with low-risk PE. By the landmark analysis at 3 months, the cumulative incidences of recurrent VTE were similar among the 3 groups both within and beyond 3 months (Massive PE: 2.9%, Sub-massive PE: 4.2%, and Low-risk PE: 3.3%, P = 0.61, and 4.3%, 8.8%, and 7.8% at 5 years, P = 0.47, respectively). After adjusting confounders, the risk of massive PE relative to low-risk PE for recurrent VTE beyond 3 months remained insignificant (adjusted HR 0.54, 95% CI: 0.13–1.51, P = 0.27). Patients with massive PE at initial diagnosis more often presented as severe recurrent PE events than those with sub-massive and low-risk PE. Conclusions In the current real-world large registry, the long-term risk of overall recurrent VTE in patients with massive PE at initial diagnosis did not significantly differ from those with sub-massive and low-risk PE beyond 3 months, although patients with massive PE at initial diagnosis more frequently developed recurrent VTE as PE with severe clinical presentation.
