High arteriovenous fistula (AVF) flow (Qa) has been shown to increase cardiovascular burden in patients on chronic hemodialysis, in particular higher frequency of pulmonary hypertension and right ventricular dysfunction. However, most data came from studies that included only patients with Qa above 1500 – 2000 mL/min. Other studies documented the safety of AVFs with lower Qa (500-1000mL/min). To reveal the links between Qa and right heart dysfunction, we analyzed cross-sectional entry data from our ongoing larger longitudinal cohort study.
