Prevalence and Risk of Pulmonary Hypertension in Chronic Kidney Disease

Pulmonary hypertension is common in chronic kidney disease patients treated by hemodialysis ( 30 %). ObjectivesThe prevalence of Pulmonary hypertension in chronic kidney disease in Baghdad teaching hospital. Patients and methodsStudy performed from April 2015 to April 2016, patients with valvular heart disease, pulmonary diseases with abnormal pulmonary function test were excluded, all patients did pulmonary function test before Doppler echo to avoid false positive results, About 80 patients, 40 with chronic kidney disease pre-dialysis 27 male and 13 female, and 40 treated by hemodialysis 22 male and 18 female from dialysis units and medical wards Results and discussionMean age was 51.6 14.2 in predialysis group, and 53.4 12.6 in dialysis group (ranging from 20 to 70 years). Dialysed patients carry increasing risk for having Pulmonry hypertension (OR = 3) compare to predialysis. Anemia increase the risk for development of PH with an OR = 3.42. As the stage of chronic kidney disease increase the incidence of PH increase in which in stage V it reach 15 % compare to stage IV 3.75 % and lower in the other stages. Patients with age above 50 represent 70.6 % of PH patients, so age increase the prevalence of pulmonary hypertension.
