Prevalence, Pathogenesis, and Prognosis of Pulmonary Hypertension in Dialysis Patients

Recruiting now

Conditions studied: Pulmonary Hypertension

In brief

This prospective multicenter longitudinal study aims to investigate the prevalence, pathogenesis, and prognosis of pulmonary hypertension in patients with end-stage renal disease undergoing chronic hemodialysis. The research seeks to identify specific clinical factors and biomarkers like angiopoietin-2 that contribute to the development of this condition, while evaluating the prognostic value of right ventricular function measured via TAPSE. Participants undergo a standardized screening echocardiogram the day after their intermediate dialysis session to determine the probability of pulmonary hypertension. Those identified as high-risk receive further diagnostic confirmation through right heart catheterization, respiratory function tests, and lung scans to clarify the underlying etiology. The protocol also evaluates the hemodynamic impact of high-flow arteriovenous fistulas and volume overload on pulmonary pressures. Clinical follow-up is conducted at baseline and subsequently at 6, 12, and 24 months to monitor patient outcomes and standardize therapeutic management according to established European guidelines.
