Effect of preload reduction by haemodialysis on doppler indices of diastolic function in patients with end-stage renal disease.
OBJECTIVE To assess the influence of preload reduction by haemodialysis on Doppler echocardiographic indices of cardiac diastolic function. METHODOLOGY Parameters of left ventricular diastolic function were measured in patients with end-stage renal disease before and after a single session of haemodialysis. Patients with valvular heart disease, coronary artery disease, cardiomyopathies, peric...
متن کاملPreload dependence of new Doppler techniques limits their utility for left ventricular diastolic function assessment in hemodialysis patients.
Left ventricular (LV) hypertrophy leads to diastolic dysfunction. Standard Doppler transmitral and pulmonary vein (PV) flow velocity measurements are preload dependent. New techniques such as mitral annulus velocity by Doppler tissue imaging (DTI) and LV inflow propagation velocity measured from color M-mode have been proposed as relatively preload-independent measurements of diastolic function...

15 صفحه اولCARDIOVASCULAR MEDICINE Is Doppler tissue velocity during early left ventricular filling preload independent?
Background: Transmitral Doppler flow indices are used to evaluate diastolic function. Recently, velocities measured by Doppler tissue imaging have been used as an index of left ventricular relaxation. Objective: To determine whether Doppler tissue velocities are influenced by alterations in preload. Methods: Left ventricular preload was altered in 17 patients (all men, mean (SD) age, 49 (8) yea...
متن کاملColor Doppler Indices of Orbital Arterial Flow in End-Stage Renal Disease Patients; Are the Changes Related to Chronic Hemodialysis or Chronic Renal Failure?
BACKGROUND Endothelial injury is a well-known complication in chronic kidney disease (CKD) and hemodialysis. One of the sites in which early vascular changes may be detected is the retina. Of course, these flow changes may not be detected in ophthalmologic exams, but it seems that color Doppler sonography of retinal arteries may be helpful in these cases. OBJECTIVES In previous studies on CKD...
