Clinical value of arterial analysis technology in the quantitative evaluation of carotid artery structure and elasticity in hypertension patients complicated with ischemic stroke
Objective To explore the clinical value of arterial analysis technology in the quantitative evaluation of carotid artery structure and elasticity in hypertension patients complicated with ischemic stroke.Methods A total of 140 patients with essential hypertension in our hospital for the first diagnosis were selected and were divided into stroke group(n=72)and non-stroke group(n=68)according to whether they were complicated with ischemic stroke,and 74 healthy volunteers with matched age and gender were selected as control group.Carotid artery structure parameters including minimum inner diameter(Dmin),maximum inner diameter(Dmax),intima-media thickness(IMT),as well as elastic parameters including stiffness index(β),arterial compliance(AC),elastic modulus(EM),single-point pulse wave velocity(PWVβ),radial strain(RS),radial strain rate(RSR),circumferential strain(CS)and circumferential strain rate(CSR)were obtained by arterial analysis technology.The differences of the above parameters among the groups were compared.Results Compared with the control group,Dmin,Dmax,IMT,β,EM and PWVβ were increased in stroke group and non-stroke group,while AC,RS,RSR,CS and CSR were decreased,and the differences were statistically significant(all P<0.05).Compared with non-stroke group,Dmin,Dmax,IMT,β and PWVβ in stroke group were increased,and the differences were statistically significant(all P<0.05).Conclusion Compared with patients with simple hypertension,the patients with hypertension complicated with ischemic stroke exhibit obvious changes of carotid artery structure and elasticity.Arterial analysis technology can be used to quantitatively evaluate carotid artery structure and elasticity in patients with hypertension complicated with ischemic stroke,and provide theoretical basis for evaluating risk stratification in patients with hypertensive ischemic stroke in clinic.
