Association of increased arterial stiffness and p wave dispersion with left ventricular diastolic dysfunction.

Background: The association between increased arterial stiffness and left ventricular diastolic dysfunction (LVDD) may be influenced by left ventricular performance. P wave dispersion is not only a significant determinant of left ventricular performance, but is also correlated with LVDD. This study is designed to compare left ventricular diastolic function among patients divided by brachial-ankle pulse wave velocity (baPWV) and corrected P wave dispersion (PWDC) and assess whether the combination of baPWV and PWDC can predict LVDD more accurately.

Significant correlation between ankle-brachial index and vascular access failure in hemodialysis patients.

Background And Objectives: Vascular access failure (VAF) is associated with increased morbidity and mortality in hemodialysis patients. The most common cause of VAF is stenosis at the arteriovenous anastomosis because of abnormal neointimal proliferation and extracellular matrix deposition. These two changes are also observed in the classic atheroma, which means atherosclerotic lesions and venous stenosis in VAF may share some similar pathogenic mechanisms.

Comparison of ankle-brachial index and brachial-ankle pulse wave velocity between patients with chronic kidney disease and hemodialysis.

Background/aims: Patients with chronic renal failure are highly predisposed to atherosclerosis. However, there is limited data about the direct comparison of atherosclerosis between patients with chronic kidney disease (CKD) and hemodialysis. The aim of this study was to compare ankle-brachial index (ABI) and brachial-ankle pulse wave velocity (baPWV) between patients with CKD and hemodialysis and thus examined the status of peripheral artery occlusive disease (PAOD) and arterial stiffness between them.

Influence of different measurement time points on brachial-ankle pulse wave velocity and ankle-brachial index in hemodialysis patients.

In order to ensure that they are reliable markers of atherosclerosis and suitable for repetitive follow-up of disease progression and management responses in hemodialysis (HD) patients, brachial-ankle pulse wave velocity (baPWV) and ankle-brachial index (ABI) should be tested to see whether they change with different measurement time points. The aim of this study was to assess whether baPWV and ABI vary according to whether they are measured before HD, after HD, or on the next dialysis-free day. Eighty-nine patients undergoing regular HD were enrolled.

Impact of preload alterations by haemodialysis on the Tei index: comparison between pulsed flow and tissue Doppler analyses.

Objective: The aim of this study is to evaluate and compare the impact of preload alterations by haemodialysis (HD) on the Tei index obtained by pulsed Doppler echocardiography (PDE-Tei index) and tissue Doppler echocardiography (TDE-Tei index).

Methods And Results: Thirty-eight uraemic patients underwent echocardiography 1 hour before and 1 hour after HD was studied. Before HD, PDE- and TDE-Tei indices had a weak correlation (r = 0.
