G-287. THE ROLE OF ARTERIOVENOUS FISTULA IN THE DEVELOPMENT OF PULMONARY HYPERTENSION AND CHANGES IN CARDIAC OUTPUT IN HEMODIALYSIS PATIENTS

Abstract

Pulmonary hypertension (PH) is a common complication in long-term hemodialysis (HD) patients, often associated with arteriovenous fistulas (AVFs), which increase cardiac output (CO) and pulmonary artery pressure (PAP). This study aimed to explore the relationship between PH and AVF formation and evaluate how AVF flow and characteristics contribute to PH development
