Hemodialysis and hemodiafiltration differently modulate left ventricular diastolic function

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...

Influence of Preload Reduction on Left Ventricular Diastolic Function in Hemodialysis Patients with Left Ventricular Hypertrophy

Objectives: The purpose of this study was to assess how the preload reduction a#ects left ventricular LV diastolic function in hemodialysis patients with LV hypertrophy. Methods: Subjects included 14 patients with LV hypertrophy receiving hemodialysis. The subjects underwent echocardiographic and pulsed Doppler examinations before and after hemodialysis, and the data were analyzed to determine ...

Modulating Left Ventricular Diastolic Function

Although both dopamine and dobutamine are potent positive inotropic agents, multiple studies indicate that dopamine may produce a rise in left ventricular (LV) filling pressure, while dobutamine often has the opposite effect. To ascertain the pharmacological and hemodynamic mechanisms responsible for the elevation in LV filling pressure observed with dopamine, we administered incremental infusi...

LEFT 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...
