Experimental investigation into radar‐based central blood pressure estimation

Statins, central blood pressure, and blood pressure amplification.

It is well established that blood pressure (BP) differs markedly between peripheral (brachial) and central arteries (aorta).1 As the pressure wave travels distally from the heart, mean BP and diastolic BP decrease slightly (1 to 2 mm Hg), but a gradual and significant increase of systolic BP (SBP) and pulse pressure (PP) occurs. This phenomenon is called BP amplification.1 The development of co...

Central blood pressure and hypertension.

During the 20th century, the brachial artery auscultatory method of blood pressure (BP) measurement has been the major basis for our understanding of clinical hypertension. First, the height of systolic (S) and diastolic (D) BP was used to define cardiovascular (CV) risk. Second, BP reduction by drug treatment was shown to be associated with a substantial decrease of CV risk in several varietie...

An Experimental Investigation into the Arching Effect in Fine Sand

In the current paper results of a well instrumented experimental procedure for studying the arching effect in loose and dense sand are presented. The apparatus comprises concentric circular trapdoors with different diameters that can yield downward while stresses and deformations are recorded simultaneously. As the trapdoor starts to yield, the whole soil mass deforms elastically. However, afte...

The Central Control of the Blood Pressure

Clinical Assessment of Central Blood Pressure

Central aortic blood pressure (CBP) is increasingly considered a better cardiovascular prognostic marker than conventional cuff brachial blood pressure. Because CBP cannot be directly measured noninvasively, it has to be estimated from peripheral pressure pulses. To assess estimated CBP appropriately, the accuracy and features of the estimation method should be considered. The aim of this revie...
