“…Increased AS has been recently recognized as an independent predictor of future cardiovascular risk [12]. Several reports have also revealed that there are good correlations between aortic root indices and pulse-wave analysis methods [34], and good correlations between aortic stiffness indices which were calculated from aortic root and indices derived from aortography and pulse-wave analysis methods [11]. This study demonstrated that there is a positive correlation between AD and LAEI and SAEI derived from the radial artery pulse-wave analysis method.…”

The results of this study show that the arterial stiffness indices (large arterial elasticity index and aortic distensibility) are abnormal in patients with BRVO compared to the healthy and hypertensive controls. Arterial stiffness may play a role in the onset or progression of BRVO. Further studies are needed to determine the exact role of AS in the pathogenesis of BRVO, and to reveal its value in predicting systemic morbidity and mortality in patients with BRVO.

“…Manual measurement and feature extraction techniques were often used in the very early days of pulse wave analysis, using various media including chart recorder paper and ruler or photographic recording/magnetic tape (e.g. Hertzman and Spealman (1937), Dillon and Hertzman (1941), Simonson (1956), Corte (1979), Cooke et al (1985), Sherebrin and Sherebrin (1990)). Recent developments in computing technology and software data analysis tools have enabled the sophisticated pre-and post-processing of physiological waveforms.…”

Photoplethysmography (PPG) is a simple and low-cost optical technique that can be used to detect blood volume changes in the microvascular bed of tissue. It is often used non-invasively to make measurements at the skin surface. The PPG waveform comprises a pulsatile ('AC') physiological waveform attributed to cardiac synchronous changes in the blood volume with each heart beat, and is superimposed on a slowly varying ('DC') baseline with various lower frequency components attributed to respiration, sympathetic nervous system activity and thermoregulation. Although the origins of the components of the PPG signal are not fully understood, it is generally accepted that they can provide valuable information about the cardiovascular system. There has been a resurgence of interest in the technique in recent years, driven by the demand for low cost, simple and portable technology for the primary care and community based clinical settings, the wide availability of low cost and small semiconductor components, and the advancement of computer-based pulse wave analysis techniques. The PPG technology has been used in a wide range of commercially available medical devices for measuring oxygen saturation, blood pressure and cardiac output, assessing autonomic function and also detecting peripheral vascular disease. The introductory sections of the topical review describe the basic principle of operation and interaction of light with tissue, early and recent history of PPG, instrumentation, measurement protocol, and pulse wave analysis. The review then focuses on the applications of PPG in clinical physiological measurements, including clinical physiological monitoring, vascular assessment and autonomic function.

“…However, assessment of the baPWV requires specialized equipment and is time consuming, affecting its practicality in everyday clinical routine. Moreover, the reliability of this technique has been called into question due to its unsatisfactory level of accuracy with regard to brachial‐ankle distance measurements, which are susceptible to the influence of body surface fat, breast size, and abnormalities of the chest or spine 27 …”

“…Moreover, the reliability of this technique has been called into question due to its unsatisfactory level of accuracy with regard to brachial-ankle distance measurements, which are susceptible to the influence of body surface fat, breast size, and abnormalities of the chest or spine. 27 In recent years, studies have found that two-dimensional speckle tracking imaging technology originally used to evaluate myocardial function can also be used as a reliable method for the evaluation of arterial stiffness. 28,29 However, due to the fact that the middle muscular layer of the three-layer structure of the arterial wall is thinner than the myocardial layer, large errors may occur due to the loss of tracking during the analysis.…”

Background: Hypertension is the most common chronic disease and the most important risk factor for cardiovascular and cerebrovascular diseases. Atheroma and arteriosclerosis plays a key role in the occurrence and development of hypertension. The purpose of this study was to evaluate the elasticity of ascending aorta wall in patients with essential hypertension (EH) using M-mode echocardiography.Materials and Methods: We prospectively enrolled 54 EH patients and 51 healthy subjects (HS). They all underwent transthoracic echocardiography to measure ascending aorta inner diameters and brachial blood pressure measurement to calculate aortic elastic variables: compliance, distensibility, strain, stiffness index, and Peterson's elastic modulus. All participants also underwent bilateral carotid ultrasonographic examination.Results: There were no significant differences in age, sex, body mass index, blood lipids, blood glucose, and ascending aorta inner diameters between the two groups.We found neither intimal thickening nor plaque formation in the left or right carotid arteries in both groups. The aortic elastic properties were significantly impaired in EH patients compared with HS.Conclusions: Echocardiography can be used for the noninvasive evaluation of ascending aorta wall elasticity as an early screening technique. Subclinical arteriosclerosis appeared to occur in the ascending aorta of patients with essential hypertension even though carotid ultrasonography was normal.
