Pulse-Wave Velocity. Pulse-wave velocity (PWV) is a measurement of arterial stiffness that is an independent predictor of cardiovascular risk.
It can be measured simply and noninvasively by measuring the carotid and femoral pulse pressures and the time delay between the two or by other methods relying on pulse-wave analysis. Objective: Aortic pulse wave velocity (aPWV) is a gold standard noninvasive marker of arterial stiffness.
aPWV is usually obtained as carotid-femoral pulse. The arterial pressure wave (which is what you see there) is a shockwave; it travels much faster than the actual blood which is ejected.
It represents the impulse of left ventricular contraction, conducted though the aortic valve and vessels along a fluid column (of blood), then up a catheter, then up another fluid column (of hard tubing) and finally into your Wheatstone bridge transducer.
“Structure and Function of Arteries”—is a topic of great importance to those who deal with arterial hypertension, since it links the source of flow, the left ventricle of the heart (whose output is pulsatile) to the peripheral tissues (whose flow is near continuous).Cited by: 2.
In subjects with end-stage renal disease (ESRD) undergoing hemodialysis, aortic pulse wave velocity (PWV) is increased independently of blood pressure level and. The goal of this study was to review the origin, clinical relevance and treatment of pulse pressure (PP).
Elevated PP is increasingly being recognized as a risk factor for cardiovascular, particularly coronary, disease. Pulse pressure is discussed in terms of both Windkessel and distributive models of the arterial circulation.

Atherosclerosis and its consequences like acute myocardial infarction or stroke are highly prevalent in western countries, and the incidence of atherosclerosis is rapidly rising in developing countries. Atherosclerosis is a disease that progresses silently over several decades before it results in the aforementioned clinical consequences.

Another major cause of aortic stenosis is the calcification of a congenital bicuspid aortic valve (% of cases), typically presenting earlier (ages 40+ to 50+).

This chapter is relevant to Section G7(iii) of the CICM Primary Syllabus, which asks the exam candidate to "describe the invasive and non-invasive measurement of blood pressure, including limitations and potential sources of error".
It deals with the ways in which the shape of the arterial waveform can be correlated with the pathology affecting the cardiovascular system. The objective of this paper is to determine the feasibility of imaging cardiovascular wall motion coupled with blood flow in vivo. Normal (n=6) and infarcted (n=5) murine left ventricles, and normal (n=5) and aneurysmal (n=4) murine abdominal aortas, were imaged in longitudinal views with a MHz ultrasound by: Your heart rate, or pulse, is the number of times your heart beats per minute.
Normal heart rate varies from person to person. Knowing yours can be an important heart-health gauge. As you age, changes in the rate and regularity of your pulse can change and may signify a heart condition or other condition that needs to be addressed.
The lower incidence of cardiovascular diseases in pre-menopausal women compared to men is well-known documented. This protection has been largely attributed to the protective effect of estrogens, which exert many beneficial effects against arterial diseases, including vasodilatation, acceleration of healing in response to arterial injury, arterial collateral growth and.

Emerging studies have shown that BBR is almost safe at conventional doses, with a relatively low incidence of adverse reactions, such as gastrointestinal discomfort, and transient increases in plasma bilirubin levels [27, 34].Although the safety of BBR is relatively high, it should be taken carefully to avoid adverse reactions in specific cases.

Too often this important discipline of engineering was acknowledged as a minorengineering curriculum within the fields of material engineering (bio-materials) or electronic engineering (bio-instrumentations). the first method that allowed quantification of baroreflex properties in humans was the ramp method, which involved rapid changes to blood pressure and was originally developed by Sleight and colleagues ().Pressor drugs were injected in a bolus or rapid infusion to induce a relatively linear “ramp” rise in blood pressure.
