E-tracking technique in the evaluations of carotid artery elasticity in patients with obstructive sleep apnea hy-popnea syndrome
Abstract：Objective To analyze the changes of carotid artery elasticity in the patients with obstructive sleep apnea hypopnea syndrome ( OSAHS) after the treatment with ET Technique .Methods Thirty patients with OS-AHS were selected and given individualized treatment for three consecutive months .The intima-media thickness ( IMT) was measured by high frequency linear ultrasound probe .An ultrasonic echo-tracking method was used to e-valuate common carotid artery elastic modulus , including pressure-strain clastic modulus ( Eρ) , stiffness parameter (β) , arterial compliance ( AC) , one point pulse wave velocity ( PWVβ) and augment index ( AI) .Results After the treatment, Eρ,βand PWVβdecreased and AC increased compared with those after the treatment (P<0.01).AI de-creased to some extent after the treatment , but no difference was found before and after the treatment ( P>0.05 ) . Conclusion ET can accurately detect the changes of carotid artery elasticity in the patients with obstructive sleep ap -nea hypopnea syndrome before and after the treatment .The changes of ET parameters can guide the clinical treatment of OSAHS and indicate atherosclerosis in an early stage .
