Abstract Number: PB2211
Meeting: ISTH 2020 Congress
Background: Half of patients report persistent dyspnea and functional impairment months to years after an episode of acute PE. Within this post-PE syndrome, the most severe cause is chronic thromboembolic pulmonary hypertension (CTEPH), which can be treated by surgery, angioplasty or pharmacotherapy. Most patients however have chronic thromboembolic pulmonary disease or are deconditioned, for which no optimal treatment strategy is currently available.
Aims: To assess the effectiveness and safety of a PE-specific rehabilitation program aimed at reducing post-PE syndrome based functional impairment.
Methods: Consecutive patients with the post-PE syndrome were referred to a specialist rehabilitation center for a 12-week personalized rehabilitation program, after CTEPH was ruled out. Disease-specific quality of life (PEmb-QoL) and maximal workload on ergometry were measured prospectively and the recently developed Post-VTE Functional Status (PVFS) Scale (Klok et al. Thromb Res 2019) was assessed post-hoc prior to start and at the end of the rehabilitation program.
Results: 22 patients started rehabilitation: 13 were female (59%) and mean age was 52 years (SD13). Median time since last PE diagnosis was 6.3 months. Median achieved maximal workload during first training was 56% of predicted (15-82%), and improved to 65% (40-165%) during final training (p< 0.003). PEmb-Qol improved after rehabilitation: mean difference was 4.1 points (95%CI 2.3 to 6.0; Figure 1). Rehabilitation resulted in significant improvement on the PVFS scale (p< 0.001) with a number needed to treat of 4 for one patient to improve in functional status (Figure 2). One patient was diagnosed with atrial fibrillation; no other complications occurred.
Conclusions: Patients with post-PE syndrome who completed the PE-specific pulmonary rehabilitation program improved in terms of maximum workload, quality of life and functional status. Our data support offering pulmonary rehabilitation to this patient group, but randomized studies are needed to validate our findings.
