Pulmonary hypertension - prevalence, risk factors, and its association with vascular calcification in chronic kidney disease and hemodialysis patients

Pulmonary hypertension (PHTN) is a recently recognized complication in dialysis and it is associated with a poor outcome. We estimated the prevalence of PHTN and its association with vascular calcification in chronic kidney disease (CKD) and hemodialysis (HD) patients. One hundred and thirteen adult...

Description
Summary:Pulmonary hypertension (PHTN) is a recently recognized complication in dialysis and it is associated with a poor outcome. We estimated the prevalence of PHTN and its association with vascular calcification in chronic kidney disease (CKD) and hemodialysis (HD) patients. One hundred and thirteen adult CKD patients were included in this study, of which 56 (49.6%) were on conservative treatment (nondialysis group) and 57 (50.4%) were on maintenance HD (dialysis group). Demographic, clinical, and biochemical parameters were collected and compared between the groups. Thirty-nine (69.6%) and 33 (57.8%) males were included in nondialysis and dialysis group, respectively. Mean age was 47.5 ± 13.7 in nondialysis group and 52.8 ± 13.9 in the dialysis group. PHTN was estimated using Doppler echocardiography and peripheral vascular calcification by lateral lumbar X-ray with aortic calcification scoring. Patients with and without PHTN and vascular calcification in dialysis and nondialysis group were compared. PHTN was found in 55 patients (48.7%) and it was high in patients on dialysis compared to nondialysis(59.6% vs. 37.5%, P <0.019). Abdominal aortic calcification was present in 35 patients (30.9%), dialysis versus nondialysis group was 22.8% and 39.3%. Increased left atrial diameter was significantly associated with PHTN (P <0.003), whereas peripheral artery calcification was not related to PHT (P = 0.248). The prevalence of PHTN in CKD was 48.7% which was higher in dialysis group than non dialysis group. Increased left atrial (LA) diameter was associated with PHTN but not peripheral arterial calcification.
