Reduction of arteriovenous access blood flow leads to biventricular unloading in haemodialysis patients

AimsPatients on chronic haemodialysis have a wide range of changes in cardiac function and structure, including left ventricular hypertrophy, dilation diastolic dysfunction or pulmonary hypertension. All these were linked to increased mortality previous studies. High-flow arteriovenous fistulas (AVF) are supposed be factor contributing their development. This study investigated the early effect surgical AVF blood flow (Qa) reduction patients with without heart failure changes.Methods resultsForty-two programme high-flow (Qa over 1500 mL/min), indicated for surgery ?1 following indications: 1.manifest failure; 2.hand ischemia; 3.advanced structural detected by echocardiography. The underwent echocardiography selection visit, before reducing six weeks thereafter. Qa led decrease mass (p = 0.02), end-diastolic volume 0.008), diameter 0.003) atrial 0.0006). Diastolic improved. Similarly, right decreased 0.000001 0.00009, respectively) together estimated artery systolic pressure. 81% suffered from hypertension prior surgery, only 36% thereafter.ConclusionThe restriction hyperkinetic circulation leads several improvements structure function, which was higher other beneficial is present even symptoms failure. contribution must considered functional changes.
