ABSTRACT
Objective To study the changes of intima-media thickness (IMT) in ambi-common carotid arteries(ambi-CCA)and how they correlated with factors related to quality intima-media thickness(QIMT).Methods According to the Chinese Arterial Stiffness Evaluation (CASE)project,the IMT of (ambi-CCA)was measured by QIMT and 2-D ultrasound respectively in 433 She people aged 15-87(mean 49.03±13.54).Diffrence and tendency were analyzed on age,gender,body mass index(BMI),pulse pressure(PP),total cholesterol(TC),and triglyceride.The whole population was classified into 3 groups by tertiles of pulse pressure.Results (1)Significant positive correlations were found between ambi-CCA IMT and pulse pressure(P<0.01).There was no significant difference between tertilel and tertile 2 of IMT in the left CCA(P>0.05)found,but with significant difference among the tertile groups,respectively(P<0.05).There were significant differences among the three groups of IMT in the right CCA,respectively(P<0.01).(2)The regression factors of IMT in left CCA were age,pulse pressure,weight,LDL-C,blood glucose (BG), TG , and theirregression equation was LCC-IMT=32.61 + 4.29 (age) + 1.77 (PP) + 1.87(weight) + 16.52(LDL-C) + 11.77(BG)-9.92(TG), with r=0.663 and r2=0.44, (P<0.001). The regression factors of IMT in right CCA were age, PP, height and their regression equation was RCC-IMT=5.19(age) + 1.61 (PP) +2.62(height) -219.36,with r=0.636 and r2=0.41 (P<0.001).Conclusion There were differences seen on IMT of CCA in the PP and position and were correlated with age, PP, body weight, LDL-C, BG, TC and body height. The difference of ambi-CCA should be called for attention.
ABSTRACT
Objective To evaluate the correlation between lesions of dorsal artery of foot and type 2 diabetes on CDFI. Methods Dorsal artery of foot was examinated in 97 cases with type 2 diabetes and 46 cases without diabetes mellitus. Results There were variable changes in intima-media of dorsal artery of foot in type 2 diabetes patients.And the patients with hyperlipidemia and hypertension showed serious lesions in the dorsal artery of foot and bifurcation of the blood vessel .Simple arteriosclerosis showed not only lesions in intima-media of dorsal artery of foot but also relative mild lesions in bifurcation of the blood vessel. Blood vessel lesion incidence in type 2 diabetes was significantly higher than that of the control group (P<0.01). Conclusions There was a significant correlation between lesions of dorsal artery of foot and type 2 diabetes patient's condition. CDFI is an effective method in evaluating patient's condition, degree and prognosis of type 2 diabetes, and has an important clinical value in early diagnosis, prognosis and treatment.Simple arteriosclerosis showed focal lesions in bifurcation of the blood vessel while dorsal artery of foot showed relatively mild lesions .
