Why the study?
The study was conducted to determine the prevalence of pulmonary hypertension and its associated factors among end-stage renal disease patients undergoing maintenance dialysis.
What is the prevalence of pulmonary hypertension and its associated factors among ESRD patients on maintenance dialysis?
Population
491 ESRD patients undergoing maintenance dialysis
Comparison
PH vs non-PH groups
Design
Retrospective study
Key result
Pulmonary hypertension was prevalent in 34.6% of ESRD patients undergoing maintenance dialysis, and was independently associated with increased right atrial diameter (OR 1.236), left atrial diameter, and reduced LVEF.

Odds Ratio: 1.236 (95% CI 1.126–1.357)
p-value: p=<0.001
Pulmonary hypertension is highly prevalent (34.6%) among ESRD patients on maintenance dialysis, with left and right atrial sizes and LVEF being independent associated factors.
Zhang et al. (2020) conducted an observational in End-stage renal disease (ESRD) on maintenance dialysis (n=491). Right atrium end-diastolic internal diameter (RA) was evaluated on Pulmonary hypertension (PASP > 35 mmHg) (OR 1.236, 95% CI 1.126-1.357, p=<0.001). Pulmonary hypertension was prevalent in 34.6% of ESRD patients undergoing maintenance dialysis, and was independently associated with increased right atrial diameter (OR 1.236), left atrial diameter, and reduced LVEF.
