Hemodialysis and hemodiafiltration differently modulate left ventricular diastolic function
BACKGROUND Renal replacement therapy may have a favorable effect on diastolic left ventricular function, but it is not clear whether hemodiafiltration is superior to hemodialysis in this field. Nitric oxide (NO) and asymmetric dimethylarginine (ADMA) may play a role in the changes of intracardiac hemodynamics, but it is not clear whether the different renal replacement methods have disparate in...
متن کاملبررسی اثر کاهش حجم بر روی پارامترهای دیاستولیک اکو کاردیوگرافی در بیماران همودیالیزی
Background: Cardiovascular problems including arterial hypertension, coronary artery diseases, congestive heart failure are prevalent among chronic hemodialyzed patients. Ultrafiltration of hemodialyzed patient's serum, which culminating in intravascular volume reduction, is frequently used during hemodialysis. One of the restrictions of the echocardiographic evaluation of the diastolic heart f...
متن کاملThe disparate effect of hemodialysis and hemodiafiltration on T-wave-peak-to-end interval (Tpe) and Tpe/QT ratio of the surface electrocardiogram
Aim: The prolongation of T-wave-peak-to-end interval (Tpe) and arrhythmogenic index (AIX) could predict arrhythmias. Developing of ventricular arrhythmias is increased during hemodialysis (HD), but the effects of hemodiafiltration (HDF) on ventricular repolarization have not been elucidated yet. Methods: Thirty patients was investigated while they were receiving hemodiafiltration over a period ...
متن کاملLEFT VENTRICULAR DIASTOLIC ABNORMALITIES IN β-THALASSEMIA MAJOR WITH NORMAL SYSTOLIC FUNCTION
In order to identify left ventricular diastolic function in patients with betathalassemia major and normal systolic function by noninvasive M-mode and Doppler echocardiography, an analytic study was designed in a university hospital in Sari. We have studied 44 patients (23 men and 21 women), mean age 15.48±2.16 (range 12 to 20) and 43 age and sex matched control subjects. Peak flow velocit...
متن کاملEffect of maintenance hemodialysis on diastolic left ventricular function in end‐stage renal disease
PURPOSE To analyze the effect of maintenance hemodialysis on left ventricular diastolic function in patients with end-stage renal disease. METHODS Study population consisted of 42 patients with end-stage renal disease. Before an arteriovenous fistula was surgically created, the patients were evaluated by conventional and Doppler echocardiography and Doppler tissue imaging. Then, the patients ...
