BACKGROUND: Patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) experience impaired health-related quality of life (HRQL). The objective of this study was to evaluate HRQL in a nation-wide sample. PATIENTS AND METHODS: This is a prospective, multicenter, non-interventional study of HRQL including 139 (89%) PAH and 17 (11%) CTEPH patients (women 70.5%; mean age, 52.2) recruited from 21 Spanish hospitals. 55% had idiopathic PAH, 34% other PAH and 11% CTEPH. HRQL was measured using the Short Form 36 Health Survey (SF-36) and EuroQoL-5D (baseline and after 6 months). RESULTS: HRQL in the patients with PAH or CTEPH was impaired. The physical component of SF-36 and the EuroQol-5D correlated with the functional class (FC). Mean EuroQol-5D visual analogical scale (EQ-5D VAS) scores were 73.5±18.4, 62.9±20.7 and 51.3±16.0 (P<.0001) in patients with FC I, II and III, respectively. Every increase of one FC represented a loss of 4.0 on the PCS SF-36 and a loss of 9.5 on the EQ-5D VAS. Eight patients who died or received a transplant during the study period presented poorer initial HRQL compared with the rest of the population. No significant changes in HRQL were observed in survivors after 6 months of follow-up. CONCLUSIONS: HRQL is impaired in this population, especially in PAH/CTEPH patients near death. HRQL measurements could help predict the prognosis in PAH and CTPH and provide additional information in these patients.
