Aim. Study was designed to assess relationship between aortic compliance and homogeneity of heart electrical activity in dialysis patients.Methods. Study group was consisted of 120 dialyzed patients; 57 (age ) were on continuous ambulatory peritoneal dialysis (CAPD) and 73 (age ) were hemodialyzed (HD). Three-dimensional vectorocardiographic (VCG) monitoring was done to assess: QRS-, and . Echocardiography was performed to assess: , , ASI (aortic siffness index).Results. ASI in HD as well as in CAPD patients was significantly higher compared to controls [resp., 5,51 (±1,32), 5,83 (±1,41), 3,07 (±1,09)]. Cut-off value of ASI was 5,67. In HD patients strong correlations between ASI and QRS-, and were determined (resp., , ; , and , ). In CAPD group were significant association between ASI and QRS-, and (resp., , ; , and , ). ASI was independently and markedly associated with: QRS-, , , ADMA, cTnT, CRP, Total-chol, LDL-chol in HD and CAPD patients.Conclusions. ASI and VCG indices are higher in HD and CAPD patients. Correlation between ASI and VCG parameters may reflect unfavourable influence of poor aortic compliance on the electrical activity of the heart in dialyzed patients. Hypertrophy aggravates repolarization disturbances in hemodialyzed patients.
