The association between augmentation index and arterial stiffness index

Advances in General Practice of Medicine, 2017
Objective To explore the association between arterial system augmentation index(AI) and brachial-ankle pulse wave velocity (baPWV). Methods All subjects were selected from a local community. The study included 1752 people living in Shijingshan district, Beijing during April to June,2010.

Increased augmentation index in patients with cystic fibrosis [PDF]

European Respiratory Journal, 2009
Increased large artery stiffness occurs in a range of inflammatory conditions indicating an ageing of the vasculature and additionally being an independent risk factor for cardiovascular events. We determined large artery parameters in adults with cystic fibrosis (CF).

A polynomial oracle-time algorithm for convex integer minimization

, 2007
In this paper we consider the solution of certain convex integer minimization problems via greedy augmentation procedures. We show that a greedy augmentation procedure that employs only directions from certain Graver bases needs only polynomially many ...

Influence of Exercise Mode on Post-exercise Arterial Stiffness and Pressure Wave Measures in Healthy Adult Males

Frontiers in Physiology, 2018
Background: Exercise mode has been reported to be an important determinant of arterial stiffness and wave reflection changes following a brief bout of exercise with inconsistent results to date. This study examined the impact of exercise mode on arterial

Efficient tensor completion for color image and video recovery: Low-rank tensor train

, 2016
This paper proposes a novel approach to tensor completion, which recovers missing entries of data represented by tensors. The approach is based on the tensor train (TT) rank, which is able to capture hidden information from tensors thanks to its ...

Radiographic and safety details of vertebral body stenting : results from a multicenter chart review [PDF]

, 2013
Background: Up to one third of BKP treated cases shows no appreciable height restoration due to loss of both restored height and kyphotic realignment after balloon deflation.

Central Pulse Wave Velocity and Augmentation Index Are Repeatable and Reproducible Measures of Arterial Function

Health Science Reports
Background and Aims Arterial function (specifically arterial stiffness) is an important cardiovascular risk factor. Pulse wave velocity (PWV) and augmentation index (Alx) are established indicators of arterial function.

Arterial Stiffness in Patients with Sarcoidosis and Obstructive Sleep Apnea

Journal of Vascular Diseases, 2023
Background: Obstructive sleep apnea (OSA) and sarcoidosis have both been implied to be risk factors for increased arterial stiffness. However, it is unclear whether an elevated apnea–hypopnea index (AHI) in sarcoidosis patients increases arterial ...

The k-apex trees with minimum augmented Zagreb index

Discrete Mathematics, 2023
For a connected graph $G$ on at least three vertices, the augmented Zagreb index (AZI) of $G$ is defined as $$AZI(G)=\sum_{uv\in E(G)}\left(\frac{d(u)d(v)}{d(u)+d(v)-2}\right)^{3},$$ being a topological index well-correlated with the formation heat of heptanes and octanes.
