Obesity-related cardiovascular disease in children is becoming more prevalent in
conjunction with the rise in childhood obesity. Children with obesity are predisposed to an …

BACKGROUND: Administration of fluid to improve cardiac output is the mainstay of
hemodynamic resuscitation. Not all patients respond to fluid therapy, and excessive fluid …

Townsend et al Vascular Research on Arterial Stiffness 699 pressure, blood flow, and
arterial diameter change with each heartbeat. In addition to the passive mechanical …

Carotid-femoral pulse wave velocity is an established method for characterizing aortic
stiffness, an individual predictor of cardiovascular mortality in adults. Normal pulse wave …

Background Aortic enlargement and impaired bioelasticity are of interest in several cardiac
and non-cardiac diseases as they can lead to cardiovascular complications. Cardiovascular …

Background—Left ventricular (LV) torsional deformation, based in part on the helical
myocardial fiber architecture, is an important component of LV systolic and diastolic …

Objective: The measurement of aortic pulse wave velocity (PWV ao) is an accepted marker
in stratifying individual cardiovascular risk in adults. There is an increasing volume of …

BACKGROUND. Until recently, our understanding of the childhood antecedents of adult
cardiovascular disease was limited mainly to autopsy studies and pathologic findings in …

Noninvasive assessment of vascular dysfunction in the pediatric population has taken
advantage of the development of high-resolution ultrasound techniques. The most frequently …

Objective To investigate whether respiratory variations in aortic blood flow velocity (ΔVpeak
ao), systolic arterial pressure (ΔPS) and pulse pressure (ΔPP) could accurately predict fluid …
