U.S., Feb. 5 -- ClinicalTrials.gov registry received information related to the study (NCT06807138) titled 'AVF Volume Blood Flow Reduction in HD Patients' on Jan. 29.
Brief Summary: Heart failure with preserved / high cardiac output is a well-known syndrome in patients with high-flow arteriovenous fistula (AVF). However, the threshold for classifying an AVF as high-flow is currently undefined. Cardio-fistular recirculation (CFR) is often used as a criterion, with values greater than 25-30% considered cardiotoxic and associated with adverse outcomes. Additionally, CFR is one of the few easily modifiable risk factors through surgical reduction of AVF volume blood flow (Qa).
The study aimed to evaluate the extent of involution of heart stru...
