LID - 1902096 [pii] LID - 10.1183/13993003.02096-2019 [doi] AB - BACKGROUND: Pulmonary endarterectomy (PEA) is the recommended treatment for eligible patients with chronic thromboembolic pulmonary hypertension (CTEPH). The Cambridge Pulmonary Hypertension Outcome Review (CAMPHOR) score is an internationally validated patient-reported outcome (PRO) measure for CTEPH. It assesses three domains: activity, quality of life (QoL) and symptoms. We assessed PROs in patients with CTEPH undergoing PEA. METHODS: This retrospective observational study of consecutive CTEPH patients undergoing PEA at the UK national PEA centre between 2006 and 2017 assessed change in CAMPHOR score from baseline (pre-PEA) until up to 5 years post-PEA. CAMPHOR scores were compared between 1) those with and without clinically significant residual pulmonary hypertension and 2) those undergoing PEA and propensity-matched CTEPH patients who were not operated on. The minimally clinically important difference (MCID) was calculated using an anchor-based method. RESULTS: Out of 1324 CTEPH patients who underwent PEA, 1053 (80%) had a CAMPHOR score recorded pre-PEA, 934 (71%) had a score recorded within a year of PEA and 784 (60%) had both. There were significant improvements between pre- and post-PEA in all three CAMPHOR domains (median+/-interquartile range activity -5+/-7, QoL -4+/-8, symptoms -7+/-8; all p<0.0001). Improvements in CAMPHOR score were greater and more sustained in those without clinically significant residual pulmonary hypertension. CTEPH patients undergoing PEA had better CAMPHOR scores than those not operated on. The MCID in CAMPHOR score was -3+/-5 for activity, -4+/-7 for QoL and -6+/-7 for symptoms. CONCLUSIONS: PROs are markedly improved by PEA in patients with CTEPH, more so in those without clinically significant residual pulmonary hypertension. CI - Copyright (c)ERS 2020.
