Background: In China, the prevalence of hypertension is high and the use of combination antihypertensive therapy is low, which contributes to inadequate blood pressure (BP) control. The availability of simplified treatments combining complementary BP-lowering agents may help more patients achieve their goals.

Methods: This Phase III, multicenter, randomized, double-blind, noninferiority study included Chinese adults with mild-to-moderate hypertension.

Background: The cardio-ankle vascular index (CAVI) measure of arterial stiffness is associated with prevalent cardiovascular risk factors, while its predictive value for cardiovascular events remains to be established. The aim was to determine associations of CAVI with cardiovascular morbimortality (primary outcome) and all-cause mortality (secondary outcome), and to establish the determinants of CAVI progression.

Methods: TRIPLE-A-Stiffness, an international multicentre prospective longitudinal study, enrolled >2000 subjects ≥40 years old at 32 centres from 18 European countries.

The present paper provides an update of previous recommendations on Home Blood Pressure Monitoring from the European Society of Hypertension (ESH) Working Group on Blood Pressure Monitoring and Cardiovascular Variability sequentially published in years 2000, 2008 and 2010. This update has taken into account new evidence in this field, including a recent statement by the American Heart association, as well as technological developments, which have occurred over the past 20 years. The present document has been developed by the same ESH Working Group with inputs from an international team of experts, and has been endorsed by the ESH.

Purpose Of Review: Aortic stiffness (AS) is widely associated with hypertension and considered as a major predictor of coronary heart disease (CHD). AS is measured using carotid-femoral pulse wave velocity (PWV), particularly when this parameter is associated with an index involving age, gender, heart rate, and mean blood pressure. The present review focuses on the interest of measurement of PWV and the calculation of individual PWV index for the prediction of CHD, in addition with the use of new statistical nonlinear models enabling results with very high levels of accuracy.

Introduction: Recommendations about lipid parameters varied from different guidelines. Aortic stiffness is a marker of vascular aging and may reflect occurrence of cardiovascular diseases. Aortic pulse wave velocity (PWV), a marker of aortic stiffness, can be measured by applanation tonometry.

Hypertensive diabetic patients remain at high cardiovascular risk despite adequate blood pressure and glycemic control. Pulse pressure amplification (PPA) is expressed as the peripheral-to-central PP ratio and provides complementary information for use in assessing cardiovascular risk. The aim of our study was to determine the clinical and biological determinants of PPA in hypertensive and diabetic patients.

Elective coronography has low diagnostic yield for obstructive coronary artery disease (CAD). We aim to determine whether non-invasive aortic stiffness assessment improves diagnostic accuracy of CAD screening by reducing the number of false-positive results from the cardiac stress test. A cross-sectional study was conducted from January 2013 to September 2014 in our medical center.

Objective: Despite adequate glycemic and blood pressure control, diabetic hypertensives remain at increased cardiovascular risk. Aortic stiffness and pulse pressure (PP) amplification may provide complementary information to correct cardiovascular risk. We aim to determine whether these hemodynamic parameters are interrelated or not and to explore the factors related to pressure pulsatility.

Pulse wave analysis is a pivotal tool to estimate central haemodynamic parameters. Available commercial devices use applanation tonometry and have been validated against invasive catheterism. We previously observed differences on a radial second systolic peak (rSPB2) between two commonly used devices: SphygmoCor (AtCor, Australia) and PulsePen (DiaTecne, Italy).

Objectives: Central blood pressure (cBP) and pulse pressure amplification (PPA) are receiving renewed interest with the increase in the availability of noninvasive techniques that enable its measurement. However, to date, there is no standardized protocol to validate their accuracy. Although invasive comparison seems intellectually ideal, it will soon raise technical and ethical issues with the growing number of devices to be validated.

Central arterial structure and function comprise a primary determinant of vascular health, and are integral to the important concept of ventriculo-vascular coupling or interaction. Central aortic stiffening is a major influence on central blood pressure, and directly relates to coronary perfusion. The joint session of the International Society of Vascular Health (Eastern Region) and the Ukrainian Congress of Cardiology was held in Kiev, Ukraine, on September 23, 2011; it provided an expert forum to discuss arterial evaluations, clinical applications, and progress toward translating arterial protection into cardiovascular benefits.
