Methods
The study included 120 patients grouped as follows: PD(n=40), HD with arterio-venous fistula (n=40) and healthy control subjects (n=40). Conventional echocardiography was performed in all patients. A classification of right ventricular function was defined in HD patients by using tricuspid annular plane systolic excursion (TAPSE), right ventricular myocardial performance index (RV-MPI), fractional area change (FAC) and tricuspid lateral annulus systolic velocity (Sa) values. Correlation analysis was performed by using right ventricular dysfunction score, clinical and echocardiographic parameters.
