Comparison of different methods for the estimation of aortic pulse wave velocity from 4D flow cardiovascular magnetic resonance
(BioMed Central, 2019-12)
Background: Arterial pulse wave velocity (PWV) is associated with increased mortality in aging and disease. Several studies have shown the accuracy of applanation tonometry carotid-femoral PWV (Cf-PWV) and the relevance ...
Reference intervals of aortic pulse wave velocity assessed with an oscillometric device in healthy children and adolescents from Argentina
(Taylor & Francis, 2019-02)
Age-related reference intervals (RIs) of aortic pulse wave velocity (Ao-PWV) obtained from a large healthy population are lacking in South America. The aims of this study were to determine Ao-PWV RIs in a cohort of healthy ...
Arterial stiffness in haemodialyzed patients: Findings and controversies
(Bentham Science Publishers, 2018-04)
Vascular research in end-stage renal diseases is an interesting field in which the characterization of arterial stiffness proved to be valuable to predict morbidity and mortality. Particularly, patients on renal replacement ...
Comprehensive assessment of local and regional aortic stiffness in patients with tricuspid or bicuspid aortic valve aortopathy using magnetic resonance imaging
(Elsevier Ireland, 2020-11)
Background: We aimed to provide a comprehensive aortic stiffness description using magnetic resonance imaging (MRI) in patients with ascending thoracic aorta aneurysm and tricuspid (TAV-ATAA) or bicuspid (BAV) aortic valve. ...
Forward and backward aortic components and reflection indexes in children and adolescents: Determinants and role in high pressure states
(Bentham Science Publishers, 2018-04)
Background: High blood pressure states (HBP) would differ in wave components and reflections indexes, which could associate clinical and prognostic implications. The study aims: 1) to characterize the association of aortic ...
Hemodialysis decreases carotid-brachial and carotid-femoral pulse wave velocities: A 5-year follow-up study
(Wiley Blackwell Publishing, Inc, 2015-03)
Aortic stiffness is a prognostic parameter associated with patient mortality. Vascular access creation has been shown to have effects on arterial stiffness both in the aorta and in the upper limb arteries in chronically ...
Central-to-peripheral arterial stiffness gradient in hemodialyzed patients depends on the location of the upper-limb vascular access
(Bentham Science Publishers, 2018-11)
Background: Pulse wave velocity ratio (PWV-ratio), a measure of central-to-peripheral arterial stiffness gradient, is calculated as a quotient between carotid-femoral and carotid-radial PWV (cf-PWV/cr-PWV). This new index ...
Analysis of aortic pressure fields from 4D flow MRI in healthy volunteers: Associations with age and left ventricular remodeling
(John Wiley & Sons Inc, 2019-02)
Background: Aging-related arterial stiffness is associated with substantial changes in global and local arterial pressures. The subsequent early return of reflected pressure waves leads to an elevated left ventricular (LV) ...
Increases in peripheral systolic pressure levels and Z-score associate gradual aortic pressure increase and functional arterial impairment in children and adolescents
(Bentham Science Publishers, 2018-12)
Background: Arterial changes associated with children and adolescents high blood pressure (HBP) states would vary depending on the arterial type, arterial indexes considered and/or on blood pressure (BP) levels. Aims: To ...
Effect of acetylsalicylic acid on arterial stiffness in pregnancy in a Colombian population: prospective cohort studyEfecto de ácido acetilsalicílico sobre la rigidez arterial en el embarazo en una población colombiana: estudio de cohorte prospectivo
