Relation Between Pulmonary Hypertension and Health-Related Quality of Life in Patients Undergoing Hemodialysis.

OBJECTIVES

Pulmonary hypertension has been reported to occur in a considerable proportion of patients with end-stage renal disease. End-stage renal disease affects the health-related quality of life of patients. There is a lack of specific information on the relation between pulmonary hypertension and health-related quality of life in patients with end-stage renal disease in the literature. We aimed to evaluate this relation in patients undergoing hemodialysis.

MATERIALS AND METHODS

This prospective case-control study included 68 patients treated with hemodialysis and 30 healthy participants as controls. Group 1 comprised hemodialysis patients with pulmonary hypertension, group 2 comprised patients without pulmonary hypertension, and group 3 were healthy subjects. Each patient's health-related quality of life was measured with the Medical Outcomes Study 36-Item Short Form health survey. Doppler echocardiography was performed to determine pulmonary artery pressure in all patients. The groups were compared with respect to health-related quality of life.

RESULTS

Pulmonary hypertension was found in 47.1% of patients (mean systolic pulmonary artery pressure of 48.9 ± 11.8 mmHg). Significant differences were observed among the 3 groups regarding the physical function, physical role, bodily pain, general health, vitality, social function, emotional role, mental health, and physical component summary (P = .001). There was no significant correlation between pulmonary artery pressure and health survey scores.

CONCLUSIONS

Hemodialysis patients had significantly lower quality of life scores than healthy subjects. There were no significant differences in terms of health survey domains between the hemodialysis patients with and without pulmonary hypertension. This may be due to the severe adverse effects of end-stage renal disease on health-related quality of life. We conclude that, because end-stage renal disease has so many adverse effects on health-related quality of life, the additional effects of pulmonary hypertension on health-related quality of life could not be revealed.
