Abstract

Objective: To explore the value of E-Tracking technology in evaluating vascular endothelial function in smokers. Methods: One hundred and thirteen of smokers were invested with different smoking period and 50 normal persons with corresponding ages were examined as controls. E-Tracking technology was performed to follow the movement tracks of the common carotid and humerus arterial wall, the following parameters were assessed: internal systolic diameter(Ds), internal diastolic diameter(Dd), elastic coefficient(Eρ), stiffness parameter(β) and compliance(AC). Results: There were no significant differences of Ds and Dd between smokers and control group(P>0.05), Eρ and β were higher in smokers than those in the control group(P<0.05). There were significant differences in the three different smoking age groups(P<0.01). AC: were lower in smokers than those in the control group(P<0.05). There were significant differences in the three groups of smokers(P<0.01). Conclusions: E-Tracking technology can be used to access the endothelial dysfunction of smokers, and it is a convenient, practical method.
