P5.31 CENTRAL PRESSURES ARE HIGHER IN PATIENTS WITH TRANSIENT ISCHAEMIC ATTACK (TIA) THAN HEALTHY ADULTS

Artery Research, 2013
Introduction: The increased risk of stroke following a Transient Ischaemic Attack (TIA) is well established. Central aortic pressure, a marker of arterial stiffness, is emerging as a predictor of cardiovascular events including stroke.

Cross‐Scale Hierarchical Targeted Delivery System Based on Small‐Scale Magnetic Robots

Advanced Robotics Research, EarlyView.
This article reviews a cross‐scale hierarchical targeted delivery system that integrates magnetic continuum robots and magnetic microrobots. By combining rapid long‐range navigation with precise microscale targeting, the system overcomes key limitations of single‐scale approaches.

P.54 Biomarkers and Haemodynamic Predictors of Left Atrial Strain in Early Hypertension

Artery Research, 2020
Background: In the early stages of atrial remodeling, increased aortic stiffness might indicate atrial fibrosis. Objective: This study aimed to investigate the association between left atrial (LA) mechanical function, assessed by two-dimensional speckle

Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic

Advanced Robotics Research, EarlyView.
Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these

DETERMINANTS OF CENTRAL AORTIC PRESSURE, AUGMENTATION AND AMPLIFICATION IN THE GENERAL POPULATION OF NOVOSIBIRSK

Атеросклероз, 2017
Objective. Currently increasing attention to the parameters of central aortic pressure (cAP). The study associations of cAP, its augmentation and amplification, with a number of metabolic parameters in the general population of Novosibirsk is of interest.

Intracranial pressure waveforms are more closely related to central aortic than radial pressure waveforms : implications for pathophysiology and therapy

, 2016
In patients with subarachnoid haemorrhage, pulsatile intracranial pressure (ICP) is more strongly associated with adverse events than mean ICP. Furthermore, patients with idiopathic normal-pressure hydrocephalus (iNPH), and pulsatile ICP of 5 mmHg or ...

Augmentation index and central aortic blood pressure in patients with abdominal aortic aneurysms

Journal of Hypertension, 2010
Abdominal aortic aneurysm (AAA) is a life-threatening disease as rupture of the aneurysm is associated with high mortality. The likelihood that an AAA will rupture is particularly influenced by the diameter of the aneurysm and the rate of expansion; the reasons for fast expansion are largely unknown.
