“…Aortic distensibility was lower and aortic stiffness was higher in patients with cystic fibrosis compared with healthy controls, even before development of pulmonary hypertension. 14 Similar changes were observed in patients with subclinical hypothyroidism, 15 sarcoidosis, 16 a1-antitrypsin deficiency, 17 erectile dysfunction, 18 obstructive sleep apnea, 19 chronic kidney disease, 20 metabolic syndrome, 21 hypertrophic cardiomyopathy, 22 and coronary artery disease (Table 1). 23 Aortic elastance was decreased in patients with a previous history of HELLP (hemolysis, elevated liver enzymes, and low platelet count) and preeclampsia which was associated with the gestational age.…”

Several methods have been applied for the evaluation of aortic elasticity. Pulsed tissue Doppler imaging of the ascending aorta is a noninvasive method applied for the evaluation of aortic elasticity in wide variety of diseases which are reviewed in this study. A comprehensive systematic literature search was carried out in November 2019 using the English databases including PubMed, Scopus, Science Direct, and Embase. All references of eligible articles and published reviews on tissue Doppler imaging were searched for relevant publications. Data were extracted according to predefined criteria (including country of study origin, patient population, number of patients in case and control groups, and results of aortic elasticity evaluation in the specific patient groups compared with controls). Two independent reviewers extracted the data, and the results were checked, compared, and edited by the third reviewer. No formal assessment of the statistics of the primary data was made. The results showed that decreased aortic elasticity is not only present in cardiovascular diseases but also can be identified in diseases of other systems that affect cardiovascular system.

“…30,41 The study has some limitations. First, even if aortic tissue strain is a new application of TDI which has proved to be useful in studying the aortic elastic properties of patients with hypertension, diastolic dysfunction with elevated filling pressures, 43 type 1 diabetes mellitus, 44 coronarosclerosis, 45 subclinical hypothyroidism, 46 and previously preeclamptic women, 21 this methodology is not yet widespread and accepted. Echocardiography is an operator-dependent method and TDI is angle-dependent, needing to be interpreted with caution if the angle between tissue and beam direction is more than 30°.…”

Elastance is a distinguished marker in diagnosing various arterial diseases as studies have reported carotid artery-related diseases linked with stiffness index (β) values greater than 5. This study was to estimate elasticity of common carotid artery by measuring the diameter during systolic and diastolic phases using pixel tracing of successive frames and blood pressure. The B-mode ultrasonography video containing arterial wall motion was captured and fragmented into image frames. Each pixel on the greyscale image was converted into RGB intensity values. The diameter of the artery as well as the thickness of the wall was measured by tracing the pixel displacements from successive frames during arterial pulsation. The study was conducted on 19 subjects aged 25-40 years. The systolic and diastolic carotid artery lumen diameters and carotid intima-media thickness were calculated as 7.1 ± 0.7, 6.3 ± 0.6 and 0.5 ± 0.05 mm (mean ± standard deviation), respectively. The mean stiffness index (β), Peterson's modulus and Young's modulus of elasticity were 5.2 ± 1.1, 69 ± 15 kPa and 453 ± 99 kPa, respectively. The pixel displacements in tunica intima, tunica media and tunica adventitia were not homogeneous, due to varied macro-constituents such as endothelial tissues, smooth muscle cells, elastin lamina, fibrous tissue and micro-constituents such as collagen, fibroblast and elastin. We found that women have smaller arteries, and the stiffness increased during the systolic phase.
