Correlation between Waist Circumference and Carotid Intima-Media Thickness in Women from Shanghai, China

Objective To evaluate whether waist circumference （WC） 〉85 cm is related to asymptomatic preclinical atherosclerosis in women from Shanghai, China. Methods A total of 2365 females aged 〉20 years recruited from 4 communities underwent physical examination and carotid artery scanning. Their carotid intima-media thickness （C-iMT） was measured. Results The C-IMT was significantly higher in overweight or obese women with their BMI 〉25.0 kg/m2 {P〈O.01） and in those with their WC _〉85 cm than in those with their WC 〈85 cm （P〈O.01）. Spearman and partial correlation analysis showed that the C-IMT was significantly correlated with WC which was independent of menopausal status. The C-IMT significantly increased with the increasing WC and reached to a platform in about 85 cm. An increment tendency was found in the subgroup with its WC 〈 85 cm （P〈O.01） while no significant tendency was found in the subgroup with its WC_〉85 cm （P=0.07）. Multiple stepwise regression analysis showed that the WC was an independent risk factor for C-IMT. In logistic regression model, the odd ratio of WC _〉80 cm, _〉80 cm and 〈85 cm and 〉85 cm for evaluating the risk of C-IMT elevation was 2.632, 2.501, and 1.878, respectively. Conclusion WC is significantly correlated with C-IMT in women from Shanghai, China, and WC_〉85 cm may be used in identifying the risk of subclinical carotid atherosclerosis.

Ultrasound Assessraent of Intima-media Thickness and Diameter of Carotid Arteries in Patients Undergoing Hemodialysis or Renal Transplantation

Renal transplant （RT） recipients have a high risk of developing cardiovascular diseases. However, the effects of renal transplantation on the development of arteriosclerosis have been controversial. The carotid intima-media thickness （CIMT） and diameter （CD） are important indicators of vascular remodeling and arteriosclerosis. In this study, 31 patients with hemodialysis （HD）, 31 RT recipients and 84 age- and gender-matched control subjects were enrolled. Their CIMT and CD were measured by ultrasonic radiofrequency tracking, and the linear regression models and Z test were used to identify the progression of arteriosclerosis and the risk factors. Compared with HD group, RT group had significantly lower CIMT and CD. CIMT was found to be associated with age, body weight, resistance index and diastolic velocity, while CD was associated significantly with age, body weight, pulsatility index, end diastolic velocity and diastolic blood pressure （DBP）, respectively. The correlation curves between CIMT and age showed the slopes of curves were decreased successively in control, RT and HD groups, and the curves between CD and age showed the slopes were decreased in order of RT 〉 control 〉 HD groups. It was concluded that CIMT and CD were significantly correlated with age in RT and moderately with age in HD patients. RT could reduce the progress of arteriosclerosis in patients with end-stage renal disease.

Relationship between Carotid Intima-Media Thickness and Diabetes Clinical Risk Factors among Normotensive Type 2 Diabetes Mellitus among Native Black African Population

Background: Type 2 diabetes mellitus is frequently associated with atherosclerosis with changes in the thickness of the intima-media of carotid arteries which causes increased risk of cardiovascular diseases. Cardiovascular disease is a major cause of morbidity and mortality in this group of patients. The carotid artery reflects the degree of atherosclerosis in the various vessels especially coronary arteries. Measurement of the carotid artery thickness with real time, relatively cheap and non-invasive ultrasonography method is used in monitoring atherosclerotic disease progression and response to treatment. This study is aimed at ultrasonographic evaluation of the carotid intima-media thickness (CIMT) in adult Type 2 Diabetic patients compared to non-diabetic healthy controls matched for age, gender and body mass index (BMI). And to also determine its association if any with selected clinical factors among a native Black African population. Methodology: This was a prospective case control study involving 54 adult type 2 diabetics and 54 adult non-diabetic controls. CIMT was measured at 3 segments of the extracranial carotid arteries by a 7.5 - 10 MHz linear transducer of a portable Mindray M5 ultrasound machine. Results: Among the native black African population studied, there was significant difference in CIMT of adult type 2 diabetics compared to healthy non-diabetics adults (p value = 0.012 and 0.001 on the right and left respectively). The mean carotid intima-media thickness in diabetics was 0.81 mm and 0.85 mm, while in non-diabetics it was 0.74 mm and 0.75 mm on the right and left respectively. The presence of diabetes showed independent positive correlation with CIMT (beta: 0.24, p value = 0.004). Age (beta: 0.30, p value = 0.001) and plasma cholesterol level (beta: 0.30, p value = 0.013) also had positive correlation with CIMT. Conclusion: There was statistically significant difference in carotid intima-media thickness between adult type 2 diabetics and age, sex matched non-diabetics. DM showed independent correlation with CIMT.

A REVIEW ON ARTERY WALL SEGMENTATION TECHNIQUES AND INTIMA-MEDIA THICKNESS MEASUREMENT FOR CAROTID ULTRASOUND IMAGES

Stroke and heart attack,which could be led by a kind of cerebrovascular and cardiovascular disease named as atherosclerosis,would seriously cause human morbidity and mortality.It is important for the early stage diagnosis and monitoring medical intervention of the atherosclerosis.Carotid stenosis is a classical atherosclerotic lesion with vessel wall narrowing down and accumulating plaques burden.The carotid artery of intima-media thickness(IMT)is a key indicator to the disease.With the development of computer assisted diagnosis technology,the imaging techniques,segmentation algorithms,measurement methods,and evaluation tools have made considerable progress.Ultrasound imaging,being real-time,economic,reliable,and safe,now seems to become a standard in vascular assessment methodology especially for the measurement of IMT.This review firstly attempts to discuss the clinical relevance of measurements in clinical practice at first,and then followed by the challenges that one has to face when approaching the segmentation of ultrasound images.Secondly,the commonly used methods for the IMT segmentation and measurement are presented.Thirdly,discussion and evaluation of different segmentation techniques are performed.An overview of summary and future perspectives is given finally.

Relationship between peripheral arterial disease, carotid intima-media thickness and C-reactive protein in elderly diabetic patients

Purpose: To study the association between carotid intima media thickness (CIMT) and high sensitivity CRP (hs-CRP) level as markers for PAD in elderly patients with DM. Subjects: A case-control study on 90 participants aged 60 years and older divided into 60 cases (30 patients with DM alone and 30 patients with DM and comorbidities) and 30 healthy controls. All were assessed by measuring CIMT, ankle brachial index (AB), and markers for cardiovascular disease such as high-sensitivity CRP (hs-CRP), total cholesterol (TC), triglycerides (TG), high density lipoprotein (HDL), and low density lipoprotein (LDL). Results: hs-CRP levels showed statistically significant difference being highest among patients with DM and comorbidities and lowest among controls (P < 0.001). Also, symptoms of PAD were significantly higher among cases than controls. ABI was able to detect PAD in many asymptomatic patients. Color changes were present in only 43.30% (n = 26) of positive PAD cases while delayed wound healing, claudication pain, rest pain, cold extremities, and trophic changes were present in 23.30% (n = 14), 16.71% (n = 10), 16.71% (n = 10), 45.00% (n = 27), and 21.7% (n = 13). Using logistic regression analysis revealed that DM, CIMT, and hs-CRP were independent predictors for PAD (OR = 4.194, 7.236, 1.003;P value = 0.044, 0.25, 0.031) after adjustment of other coronary risk factors such as sex, smoking, hypertension, TC, and TG. Conclusion: Diabetic elderly have higher prevalence of asymptomatic PAD thannon-diabetics using solely ABI. DM, CIMT, and hs-CRP are independent predictors for the occurrence of PAD. Hs-CRP levels are highest among diabetics with comorbidities.

Determining factors for carotid mean/max intima-media thickness and brachial flow-mediated dilation in healthy young women

Background: Many factors can contribute to atherosclerotic-type vascular changes in older individuals or men. Thus, confining the investigation to young women with no clinical evidence of the condition could enhance understanding of the early stages of cardiovascular disease. The aim of this study was to determine whether carotid mean/max intima-media thickness (IMT) and brachial flow-mediated dilation (FMD) values, which are well-known event-related indices, are associated with laboratory data and the other vascular indices of atherosclerosis in healthy young women. Methods: Carotid mean/max IMT and brachial FMD were measured in young women with no clinical evidence of atherosclerosis (n = 110;mean age, 39 years) who were instructed not to eat, drink or smoke after 9 PM the evening before testing. All participants also underwent laboratory assessment, including simultaneous measurements of arterial stiffness such as augmentation index (AI), cardioankle vascular index (CAVI) and brachial-ankle pulse wave velocity (baPWV). Results: Mean IMT was signifi-cantly and positively associated with age (p = 0.002), CAVI (p = 0.044), low-density lipoprotein-cholesterol (LDL-C, p = 0.047) and high-sensitive C-reactive protein (hs-CRP, p = 0.002) values but was not related to FMD, AI, baPWV or triglycerides (TG) in the multivariate regression analysis. Similarly, max IMT was positively associated with age (p p = 0.003) and hs-CRP (p = 0.005) values but was not related to FMD, AI, CAVI, baPWV, TG or blood pressure level in the multivariate regression analysis. The association between LDL-C and max IMT was much stronger than that between LDL-C and mean IMT. Brachial FMD was positively associated only with heart rate in the multivariate regression analysis. Conclusions: These results suggest that mean IMT more closely represents the sclerotic aspect of vascular change, whereas max IMT represents the atherotic aspect in healthy young women. Although the relationship between the autonomic nervous system and heart rate is well-known, there may be a complex interaction between the autonomic nervous system and endothelial function.

Correlation of the carotid intima-media unevenness and stiffness with serum illness indexes in patients with type 2 diabetes mellitus

Objective: To investigate the correlation of the carotid intima-media unevenness and stiffness with serum illness indexes in patients with type 2 diabetes mellitus. Methods: A total of 118 patients with type 2 diabetes mellitus who were treated in this hospital between February 2016 and August 2017 were selected as the diabetes group, and 100 healthy volunteers who received physical examination in this hospital during the same period were selected as normal control group. The differences in carotid intima-media unevenness and stiffness levels as well as serum levels of insulin resistance indexes and inflammatory adipocytokines were compared between the two groups of subjects. Pearson test was used to assess the correlation between carotid intima-media parameter levels and above serum illness index levels in patients with type 2 diabetes mellitus. Results: IMIsqrt and PWV levels in diabetes group were higher than those in normal control group;serum FINS and IRI levels were higher than those in normal control group whereas ISI level was lower than that in normal control group;serum APN content was lower than that in normal control group whereas LEP and SAA contents were higher than those in normal control group. Pearson test showed that the IMIsqrt and PWV levels in patients with type 2 diabetes mellitus were directly correlated with serum insulin resistance index levels and inflammatory adipocytokine contents. Conclusion: Carotid intima-media unevenness and stiffness both increase in patients with type 2 diabetes mellitus, and could objectively reflect the insulin resistance and systemic micro-inflammatory state.

Relationship between Waist Circumference and Elevation of Carotid Intima-media Thickness in Newly-diagnosed Diabetic Patients

Objective Waist circumference, as a brief indicator of visceral obesity, is associated with multi-metabolic disorders and cardiovascular diseases. The present study was aimed to find out the relationship between waist circumference and carotid intima media thickness （C-IMT）, as well as the best waist circumference cutoff for identifying C-IMT elevation in Chinese male patients with newly-diagnosed diabetes. Methods Five hundred and seventy-eight patients from Department of Endocrinology and Metabolism in Shanghai Sixth People＇s Hospital affiliated to Shanghai Jiao Tong University were enrolled. Both physical examination （for measurement of waist circumference） and carotid ultrasonography （for measurement of C-IMT） were performed. Results After grouping according to the quartiles of C-IMT, the waist circumference increased across all its quartiles. The waist circumference in 3rd and 4th quartiles （90.7_＋9.8 cm and 90.8＋9.6 cm） was significant higher than in 1st and 2nd quartiles （P〈0.05）. When subjects were divided into 4 groups according to waist circumference, the C-IMT of subjects with waist circumference 90-95 cm was significant higher than that of subjects with waist circumference 85-90 cm and less than 85 cm respectively （P〈0.05）. Both spearman and partial correlation analysis showed that C-IMT was positively correlated with waist circumference （P〈0.01）. C-IMT was found significantly elevated with the increase of waist circumference. Multiple stepwise regression analysis showed that waist circumference was one of the independent risk factors of C-IMT. After an average of 2.23_＋0.85 years follow up, there was a significant elevation of C-IMT in the group with baseline waist circumference over 90 cm P〈0.05）, while no significant difference was detected in the group with baseline waist circumference less than 90 cm （P=0.27）. Logistic regression showed that baseline waist circumference over 90 cm was associated with a relative risk to C-IMT elevation of 1.132 （95% CI 1.043-1.431, P〈0.05）. Conclusion Among newly-diagnosed diabetic male patients, waist circumference over 90 cm not only reflects sub-clinical atherosclerosis in early stage, but also predicts the progression of atherosclerosis.

目的探讨老年钙化性心脏瓣膜病患者颈动脉斑块积分(Crouse积分)、内膜中层厚度(intima media thickness,IMT)与瓣膜钙化程度的关系。方法回顾性分析2020年4月至2023年3月收治的106例老年钙化性心脏瓣膜病患者的临床资料(观察组)。另选择90例颈动脉粥样硬化的非心脏瓣膜病患者作为对照组1、选取95例非老年钙化性心脏瓣膜病患者作为对照组2。单因素方差分析检验三组Crouse积分、IMT、管腔狭窄程度及老年钙化性心脏瓣膜病不同心瓣膜钙化程度患者Crouse积分、IMT。Pearson分析Crouse积分、IMT与心瓣膜钙化程度的相关性;受试者工作特征(ROC)曲线分析Crouse积分、IMT对老年钙化性心脏瓣膜病患者瓣膜钙化的预测价值。结果观察组Crouse积分、IMT、管腔狭窄程度均明显高于对照组1和对照组2(P<0.05)。老年钙化性心脏瓣膜病不同心瓣膜钙化程度患者Crouse积分、IMT比较:1级<2级<3级(P<0.05)。相关性分析结果显示,Crouse积分、IMT与老年钙化性心脏瓣膜病瓣膜钙化程度均呈明显正相关关系(r=0.585、0.623,P<0.05)。绘制Crouse积分、IMT预测老年钙化性心脏瓣膜病患者瓣膜钙化的ROC曲线示,Crouse积分、IMT联合预测的AUC为0.802(95%CI为0.738~0.867),明显高于各指标单一预测的AUC,最佳诊断敏感度和特异度分别为0.887、0.794(P<0.05)。结论老年钙化性心脏瓣膜病患者Crouse积分、IMT存在异常增高,且与瓣膜钙化程度呈正相关,测量上述指标有助于对心脏瓣膜钙化程度进行评估。

载脂蛋白B联合颈动脉内膜中层厚度对冠心病的预测价值

目的探讨血清载脂蛋白B(apoB)联合颈动脉内膜中层厚度(CIMT)在冠心病中的预测价值。方法回顾性分析2020年1—6月在右江民族医学院附属医院就诊的胸痛疑似冠心病并行冠脉造影的患者210例,根据冠脉造影结果,分为冠心病组和非冠心病组。所有患者检测血清apoB、行颈动脉彩超检查。分析两组患者血清apoB、CIMT、斑块差异,采用受试者工作特征曲线(ROC)分析apoB、CIMT以及二者联合对冠心病的预测价值。结果冠心病组血清apoB、CIMT、颈动脉斑块比例明显高于非冠心病组,差异有统计学意义(P<0.05);冠心病多支病变患者血清apoB、CIMT明显高于单支病变患者,差异有统计学意义(P<0.05);血清apoB和CIMT预测冠心病的价值差异无统计学意义(P>0.05)。两者联合预测冠心病的ROC曲线下面积为0.865,诊断的敏感度和特异度分别为93.20%和63.30%,两者联合预测冠心病的价值优于单独使用血清apoB、CIMT,差异有统计学意义(P<0.05)。结论血清apoB联合CIMT能提高对冠心病的预测价值。
