0140 : Prevalence of pulmonary hypertension in patients undergoing hemodialysis

Abstract

Pulmonary hypertension (PH) is one of the most important accompanying comorbidities with hemodialysis in patients with end-stage renal disease. The prevalence of hemodialysisinduced PH is still a subject of debate. The goal of the present work was to determine the prevalence of PH in patients undergoing hemodialysis. This study was carried out on 111 patients undergoing hemodialysis for at least 6 months. Pulmonary artery pressure (PAP) was measured using echocardiography, and a value equal to or higher than 35mm Hg was considered PH. The relationship of a high PAP with demographic and clinical characteristics of the patients was assessed. A total of 111 patients were included in the study. The mean of age was 44 ± 14 years. The mean duration of hemodialysis was 146 ± 80 months. The most common cause of endstage renal disease was Glomerulonephritis. The mean ejection fraction and PAP were 62,5 ± 10,5% (range, 29% to 81%) and 26,6 ± 12 mmHg (range, 11 mmHg to 100 mmHg), respectively. Overall, 16% of the patients had PH. These patients were more likely to have low ejection fractions, valvular calcifications and valvulopathy. They were also older than other patients. Our findings show that PH is associated with duration age, ejection fraction, and valvular calcifications. Due to the high prevalence of PH among hemodialysis patients, it is necessary to screen this disorder and minimize its effects.
