Anxiety, Depression and Quality of Life in Pulmonary Hypertension: A Comparison of Incident and Prevalent Cases.

INTRODUCTION

Anxiety and depression are common in pulmonary hypertension (PH) and health-related quality of life (HRQoL) is reduced. Sufficient analyses in incident and prevalent patients are lacking, so we provide a comparative analysis of these groups with focus on anxiety, depression and HRQoL.

METHODS

Depression, anxiety and HRQoL were retrospectively analyzed by Hospital Anxiety and Depression Scale (HADS) and Short Form 36 questionnaire in 91 prevalent and 21 incident PH outpatients from a German tertiary care center specialized in PH. The acquired data as well as hemodynamic and functional parameters of prevalent and incident cases were compared.

RESULTS

HRQoL was reduced in both cohorts of patients. Incident patients had significantly worse HRQoL in physical dominated scales than prevalent patients (physical component summary score: p = 0.02; physical role performance: p < 0.01). Depression and anxiety were more pronounced in prevalent patients (elevated depression scales: 28.6% of incident group, 35.2% of prevalent group, elevated anxiety scores: 28.6% of incident group, 39.6% of prevalent group). The groups did not differ in hemodynamic data, but incident patients had significantly lower cardiac biomarkers such as NT-proBNP (p = 0.016) and hs-troponin (p = 0.017). The time since diagnosis was a predictor of the subscale physical role performance (p < 0.001).

CONCLUSION

Physical domains of HRQoL seem to be more limited in incident patients with PH. Anxiety and depression are frequent in both groups. A screening for anxiety and depression is important from the onset of the diagnosis, and patients should receive appropriate therapy to improve HRQoL, anxiety and depression.
