Abstract:
Objective To investigate the relationship among ultrafiltration (UF), diurnal rhythm of blood pressure (BP) and cardiac structure and function in hemodialyzed(HD) patients. Method 42 hemodialyzed patients were studied. Intensified UF during routine HD were given to them for 4 weeks. Before and after 4 weeks, everyone received 24 hours ambulatory blood pressure monitoring and cardiac doppler and recorded diameter of left atrium (LAD) ,left ventricle (LVEDD), thickness of posterior wall of left ventricle during end stage of diastolic period (LVPWT) ,thickness of interventricular septum(IVST) ,ejection fraction (EF). Result In hemodialyzed patients, non-dipper hypertension was much more than dippers (P < 0.05). There was significant difference between nocturnal BP and cardiac structure before and after 4 weeks of hemodialysis ( P < 0.05 ). Conclusion Nocturnal hyperten- sion of hemodialyzed patients is related to hypervolemia. Intensive ultrafihration can improve nocturnal hypertension and eardiac function.
