Ultrasound strain imaging, particularly speckle-tracking echocardiography, is a feasible and valuable non-invasive method for evaluating regional arterial function and early vascular aging.
Speckle-tracking ultrasound and velocity vector imaging offer a promising non-invasive method to evaluate regional arterial mechanics and vascular aging, though further large-scale validation is needed.
It is well known that arterial function relates to cardiovascular morbidity and mortality. The noninvasive technology for the assessment of arterial function has developed as the importance of prevention of early cardiovascular disease has been emphasized. Over 2-D and Doppler echocardiography, speckle-tracking echocardiography has emerged as a valuable ultrasound imaging technique that allows for an objective and quantitative evaluation of global and regional myocardial function. Recently, several studies have extended its applicability beyond cardiac chambers, such as artery. Measurement of carotid arterial strain with speckle tracking ultrasound has been shown to be feasible and reliable. This review describes the new ultrasound techniques to assess arterial function and their clinical implications.

Yang et al. (2015) conducted a review in Vascular alteration and arterial aging. Ultrasound strain imaging (speckle-tracking echocardiography) was evaluated. Ultrasound strain imaging, particularly speckle-tracking echocardiography, is a feasible and valuable non-invasive method for evaluating regional arterial function and early vascular aging.
