The feasibility for dicrotic augmentation index to replace tidal augmentation index

2014 IEEE International Conference on Information and Automation (ICIA), 2014
Aortic augmentation index (AI) has great significance in predicting cardiovascular diseases. To obtain AI the tidal wave crest will be need, which is difficult to identify sometimes. Fortunately, it is easier to obtain the dicrotic wave crest, which can derive a parameter called dicrotic augmentation index (DAI).

Augmentation index is associated with cardiovascular risk

Journal of Hypertension, 2002
Augmentation index is a parameter measured by pulse wave analysis (PWA) and is used as a surrogate measure of arterial stiffness. The aim of this study was to assess whether augmentation index is associated with cardiovascular risk, as well as to evaluate whether the determinants of augmentation index are different in patients with cardiovascular ...

Augmented low-index waveguides (Conference Presentation)

Smart Photonic and Optoelectronic Integrated Circuits XXII, 2020
Augmented low index waveguides consist of a dual core waveguide layer where the transverse electric (TE) mode is confined to the high index region and the transverse magnetic (TM) mode is confined to the lower index core. The result is a large difference in propagation constants between the TE and TM modes which has applications for on-chip ...

Augmented Velocity Index: A New Doppler Index Associated with Arterial Stiffness

Ultrasound in Medicine & Biology, 2019
Augmented Velocity Index (Avi) is a new Doppler index developed to quantify velocity changes at the late systolic peak. We examined its reliability, association with arterial stiffness and cardiovascular risk factors. The Avi is calculated as (late systolic peak velocity - early systolic peak velocity)/(highest peak systolic velocity - end-diastolic ...

Augmentation index in resistance to thyroid hormone (RTH)

Clinical Endocrinology, 2009
SummaryObjective  Resistance to thyroid hormone (RTH) is associated with a varied clinical presentation. The cardiac effects of RTH have been described but vascular function has yet to be fully evaluated in this condition. We have measured the arterial function of those with RTH to assess any vascular changes.Design  An observational study.Patients ...

Reduction in augmentation index after successful renal transplantation

Clinical and Experimental Nephrology, 2012
Patients of end stage renal disease (ESRD) have an increased risk of cardiovascular events. Arterial stiffness is an established independent predictor of cardiovascular morbidity and mortality in ESRD patients. Carotid femoral pulse wave velocity (c-f PWV) and augmentation index (AI) are the indices which are used for the noninvasive assessment of ...

Aortic augmentation index in endurance athletes: a role for cardiorespiratory fitness

European Journal of Applied Physiology, 2016
Endurance exercise improves cardiovascular health and reduces mortality risk. Augmentation index (AIx) reflects adverse loading exerted on the heart and large arteries and predicts future cardiovascular disease. The purpose of this study was to establish whether endurance athletes possess lower AIx and aortic blood pressure compared to healthy controls,

Prediction of central Augmentation Index in healthy adults

The Journal of Sports Medicine and Physical Fitness
Central Augmentation Index (AIx) is a surrogate marker of large artery stiffness that may provide valuable insight to cardiovascular health. The aim of this study was to evaluate the relationship between AIx and components of physical fitness.One hundred eighty-five healthy men and women (aged 20-79 years) underwent non-invasive assessment of arterial ...

Augmented eccentric connectivity index of Fullerenes

2014
Fullerenes are carbon-cage molecules in which a number of carbon atoms are bonded in a nearly spherical configuration. The augmented eccentric connectivity index of graph G is defined as £(G)=∑u eV(G)M(u)e(u)-1, where e(u)  is defined as the length of a maximal path connecting u to another vertex of G and M(u) denotes the product of degrees of all ...
