An inverse, linear relationship between AIx is demonstrated, likely due to alterations in the timing of the reflected pressure wave, produced by changes in the absolute duration of systole, which may explain the lack of rise in central systolic pressure during incremental pacing despite an increase in peripheral pressure.
Aortic pulse wave velocity improves cardiovascular event prediction: an individual participant meta-analysis of prospective observational data from 17,635 subjects.
Noninvasive assessment of arterial stiffness and risk of atherosclerotic events.
The effects of current and future cardiovascular drugs on arterial stiffness are discussed, as is the relationship between arterial elasticity and endothelial function.
Reproducibility of pulse wave velocity and augmentation index measured by pulse wave analysis
PWA is a simple and reproducible technique with which to measure PWV and AIx and may, therefore, be suitable for large-scale population and intervention studies investigating the clinical relevance of vascular stiffness.
Pulse transit time measured from the ECG: an unreliable marker of beat-to-beat blood pressure.
The relationship between rPTT, preejection period (PEP; the R-wave/mechanical cardiac delay), and BP would vary with different vasoactive drugs, but the relationship is not reliable enough to be used as a surrogate marker of SBP, although it may be useful in assessing BP variability.
Endothelin as a regulator of cardiovascular function in health and disease
Results of most studies suggest that generation of, or sensitivity to, endothelin-1 is no greater in hypertensive than it is in normotensive subjects, but the deleterious vascular effects of endogenous endotheli-1 may be accentuated by reduced generation of nitric oxide caused by hypertensive endothelial dysfunction.
Endothelial function and dysfunction. Part I: Methodological issues for assessment in the different vascular beds: a statement by the Working Group on Endothelin and Endothelial Factors of the…
The most relevant methodological issues in the research on endothelial function and dysfunction are summarized in this paper.
Circulating microRNAs as potential markers of human drug‐induced liver injury
This work provides the first evidence for the potential use of miRNAs as biomarkers of human drug‐induced liver injury by examining these molecules, for the first time, in humans with APAP poisoning.
Spironolactone versus placebo, bisoprolol, and doxazosin to determine the optimal treatment for drug-resistant hypertension (PATHWAY-2): a randomised, double-blind, crossover trial
Mechanistic biomarkers provide early and sensitive detection of acetaminophen-induced acute liver injury at first presentation to hospital
Elevations in plasma miR‐122, HMGB1, and necrosis K18 identified subsequent ALI development in patients on admission to the hospital, soon after acetaminophen overdose, and in patients with ALTs in the normal range.
