ABSTRACT
in patients undergoing regular hemodialysis [HD] due to end-stage renal disease [ESRD]
Study Design: Cross-sectional analytical study
Place and Duration of Study: Nephrology Department, Lahore General Hospital, Pakistan, from July to December 2016
Methodology: Fifty patients with end-stage renal disease. Various parameters, including the pulmonary arterial systolic pressure [PASP], were recorded. Pulmonary arterial pressure greater than 25 mmHg at rest was defined as pulmonary hypertension. It was further divided into three sub categories as mild [25-40 mmHg], moderate [40-55 mmHg], and severe [greater than 55 mmHg]. Data were correlated with age, gender, body mass index, systemic hypertension, diabetes, duration of dialysis, and Hb [hemoglobin] concentration. Data was analysed using SPSS version 23.0
Results: The median [IQR] duration of dialysis was 12 [11.25] months. Eighteen [36%] patients were found to have PH.It is greater in patients who had been on dialysis for more than 5 months. A positive association was seen between the duration of dialysis and the prevalence of PH [p=0.024]
Conclusion: A considerable number of patients on hemodialysis have pulmonary hypertension which is associated with the longer duration of maintenance hemodialysis
