Prevalence of right ventricular dysfunction in relation to type of vascular access in chronic hemodialysis patients: monocentric study

ABSTRACT

Background: chronic renal failure [CRF] is associated with significantly increased morbidity and mortality. Chronic renal failure affects almost every system of the body and results in various functional and structural abnormalities. Life-sustaining haemodialysis [HD] requires durable vascular access [VA] to the circulatory system. An arteriovenous fistula is currently considered the gold standard access for hemodialysis, as it has lower risk for infection, lower tendency to thrombotic occlusion, greater blood flow, reduced treatment time and is less expensive to maintain than alternative vascular access methodologies. Patients on hemodialysis have several risk factors for developing PH LV systolic and diastolic dysfunction, volume overload, endothelial dysfunction and sleep-discorded breathing
