Purpose: Hypertension is considered an important cardiovascular (CV) risk for uremic patients on hemodialysis (HD). Its main pathogenetic factor is the extracellular fluid volume increase.
Methods: This study aimed to evaluate the water distribution by electric bioimpedence (BIA) in hypertensive uremic patients treated with convective hemodialysis (HD) (group A) and with diffusive HD (group B). The patients were on antihypertensive therapy: angiotensin-converting enzyme (ACE)-inhibitors, beta blockers, calcium antagonists and angiotensin II (ATII) antagonists.
Results: The BIA analysis demonstrated that the total and extracellular body water had the same distribution in the two groups with no statistical differences (Student's t-test); although the interdialytic weight gain was higher in group B than in group A.
Conclusions: Blood pressure (BP) was treated by less drug use in patients on convective HD than in patients on diffusive HD.
