Blood flow image technique for evaluating the effect of hypertension on carotid atherosclerosis / 重庆医学

ABSTRACT

Objective To investigate the effect of hypertension on carotid atherosclerosis ,and the clinical significance of BFI technique in the diagnosis of carotid atherosclerosis .Methods Using BFI technique and CDFI technique to detect 198 cases of pa-tients with hypertension(hypertension groups) and 200 cases with normal blood pressure(control group) of carotid internal-media thickness(IMT) and the number of atherosclerotic plaque .To explore the relationship between hypertension and carotid atheroscle-rosis .Results IMT and the detection rate of plaque of hypertension groups was significantly higher than which of control group (P<0 .01) .In hypertension groups ,the higher of blood pressure levels ,the higher carotid IMT and the detection rate of plaque(P<0 .01 or P<0 .05) .The detection rate of plaque in BFI technique was higher than which in CDFI technique (P<0 .01) .Conclusion hypertension can aggravate carotid atherosclerosis ,and the higher blood pressure levels ,the more obvious of carotid atherosclerosis . BFI technique is useful for the detection of carotid atherosclerosis .
