BACKGROUND: The objective of this prospective study was to evaluate the impact of exercise capacity, mental disorders, and hemodynamics on quality-of-life (QoL) parameters in patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH).
METHODS: Sixty-three patients with invasively diagnosed PAH (n = 48) or CTEPH (n = 15) underwent a broad panel of assessments, including cardiopulmonary exercise testing (CPET), 6-minute walking distance (6-MWD), World Health Organization functional class (WHO-FC), and assessment of hemodynamics. QoL was evaluated by the 36-item Medical Outcome Study Short Form Health Survey Questionnaire (SF-36). Exercise capacity, hemodynamics, age, gender, and mental disorders (anxiety and depression) were assessed for association with QoL subscores by uni- and multivariate regression analyses.
RESULTS: Exercise capacity, WHO-FC, oxygen therapy, symptoms of right heart failure, right atrial pressure, and mental disorders were significantly associated with QoL (p < 0.05). In the stepwise backward selection multivariate analysis, depression remained an independent parameter in seven of eight subscales of the SF-36. Furthermore, peak oxygen uptake (peakVO2) during CPET, 6-MWD, anxiety, long-term oxygen therapy, right heart failure, and age remained independent factors for QoL. Hemodynamic parameters at rest did not independently correlate with any domain of the SF-36 QoL subscores.
CONCLUSIONS: Mental disorders, exercise capacity, long-term oxygen therapy, right heart failure, and age play important role in the quality of life in patients with PAH and CTEPH.
