Abstract:
Objective To evaluate the feasibility of quality intima-media thickness (QIMT) in assessing function of common carotid artery (CCA) though cold pressure test(CPT). Methods Thirty healthy subjects[mean age(24.68±1.73) years old]were underwent 2D and QIMT examination under the normal quiescent and CPT condition respectively. The diastolic and systolic diameters of right-CCA were measured respectively. Corresponding the changed range and rate were calculated. After a week,under the same condition, 10 subjects who were chosen randomly were examination again to accept reproducibility test. Results The maximal and minimal diameters,changed range and rate of diameters were wider when subjects suffered CPT and measured by QIMT(P < 0.05). There was no significant difference of diameters between CPT and quiescent condition which measured by 2D. The maximal diameters measured by QIMT were well concordance [in group: r=0.92, P < 0.0001 :mean difference(0.027±0.012)mm]. Conclusion The function of CCA would be evaluated by QIMT.
