spherical equivalent (se) has not been linked to increased cardiovascular morbidity. methods: 132 hungarian twins (age 43.3±16.9 years) underwent refraction measurements (huvitz mrk-3100 premium autorefractokeratometer) and oscillometry (tensiomed arteriograph). results: heritability analysis indicated major role for genetic components in the presence of right and left se (82.7%, 95%ci, 62.9 to...

introduction: arterial stiffness is an important predictor of cardiovascular risk. several indices have been  introduced to estimate the arterial stiffness based on the changes in the brachial blood pressure. since the  substitution  of  the  blood  pressure  changes  in  the  central  arteries  such  as  carotid  with  the  blood  pressure  changes in the brachial results in error in the blood...

background: both increased arterial stiffness and hyperuricaemia are associated with elevated cardiovascular risks. little is known about the relations of serum uric acid (ua) level to regional arterial stiffness and wave reflection. the aim of the study was to investigate the gender-specific association of serum ua and indices of arterial function in a community-based investigation in china. m...

Introduction: Coronary artery disease secondary to atherosclerosis is the most common cause of mortality. Coronary angiography is the most precise method for determining the extent of disease in the coronary vascular bed. Arterial stiffness has been proposed as a marker of atherosclerosis in some studies. One of the noninvasive methods for the determination of arterial stiffness is Doppler echo...

  Background & Objective : Several indices have been introduced to estimate arterial stiffness that based on changes in brachial blood pressure. But because of the error resulted by the substitution of brachial blood pressure instead of the other central arteries, such as carotid, it will be very important to present elastic parameter based on the mechanical models without any emphasis on brach...

vitamin D deficiency is associated with many cardiovascular disorders. Arterial stiffness responses also depend on nutritional and exercise. Therefore, the study aimed to investigate the relationship between arterial stiffness response after glucose uptake and exercise with baseline levels of vitamin D in inactive men and women. The present study was an analysis correlation study, and the subj...

background: pulse wave velocity (pwv) is widely used for estimating the stiffness of an artery. v arious invasive and non-invasive methods have been developed to determine pwv over the years. in the present research , the non-invasive estimation of the pwv of large arteries was used as an index for arterial stiffness. methods: a dynamic model based on the navier-stokes equations coupled to elas...

Measurements of biomechanical properties of arteries have become an important surrogate outcome used in epidemiological and interventional cardiovascular research. Structural and functional differences of vessels in the arterial tree result in a dampening of pulsatility and smoothing of blood flow as it progresses to capillary level. A loss of arterial elastic properties results a range of link...
