Pulmonary hypertension (PH) has been commonly found in patients undergoing renal replacement with haemodialysis via an arterio-venous graft or fistula, and is characterized by elevations in the pulmonary arterial pressure and pulmonary vascular resistance (PVR) that eventually result in right ventricular failure and even premature death. Chronic renal failure (CRF) is most often seen with patients with PH. Hence based on above observations this study was planned to know the prevalence of PH in patients who are on conservative management, haemodialysis or continuous ambulatory peritoneal dialysis. The study was conducted on 80 patients diagnosed with chronic kidney disease and on conservative or maintenance haemodialysis were included in the present study. The patients above 12 years of age and suffering from chronic kidney disease oron dialysis were included in the study. The pregnant females and patients having other diseases were excluded from the study. From the above data it can be concluded that Pulmonary hypertension is positively correlated with clinical parameters like RRT-haemodialysis, A-V fistula, duration of dialysis and biochemical parameters like low haemoglobin, low sr. bicarbonate, high levels of uric acid, BUN, creatinine.
