Artery Research

Arterial stiffness and excessive pressure pulsatility have emerged as important risk factors for cardiovascular disease. Arterial stiffness increases with age and in the presence of traditional cardiovascular disease risk factors, such as hypertension, diabetes and lipid disorders. Pathologic stiffening...

Background: We examined several measures of ventricular–vascular load as they relate to ECG-derived measures of left ventricular (LV) morphology in a cross-section of 19 young African American and 19 white men. Methods: Measures of steady and pulsatile LV load derived from aortic blood pressure waveforms...

In vivo measurements of wall shear stress (WSS), a determinant of endothelial cell function and gene expression, have shown that theoretical assumptions regarding WSS in the arterial system and its calculation are invalid. In humans mean WSS varies along the arterial tree and is higher in the carotid...

In this paper, we briefly revise some of the most widely applied methods to non-invasively assess pressure wave reflection (augmentation index) and arterial stiffness (pulse wave velocity; PWV) in clinical vascular research. It is clear that the pressure waveform alone provides insufficient information...

An easier approach of teaching the three dimensional nature of arteries of the brainstem is being proposed and aids the understanding of clinical vascular conditions of the brain. Various regions of a standing student appear to represent different parts of the brainstem: head (midbrain), trunk (pons),...
