检查心血管疾病、血管疾病的过程,需用非侵袭性和定量方法检测早期动脉粥样硬化,高分辩 B型超声检查法能直接看到腔和血管壁特征,可能早期检测颅外颈动脉粥样硬化。本研究乃是定量评价糖尿病患者颈动脉粥样硬化和无危险因子的正常非糖尿病受检者、调查颈动脉粥样硬化如糖尿病、高脂血、高血压、肥胖和吸烟的危险因子间的关系。 Check the cardiovascular disease, vascular disease process, the need for non-invasive and quantitative detection of early atherosclerosis, high-resolution B-mode ultrasound can directly see the characteristics of the lumen and the vessel wall, early detection of extracranial carotid atherosclerosis Like sclerosis. This study was designed to quantitatively assess normal nondiabetic subjects with carotid atherosclerosis and no risk factors in diabetic subjects and to investigate the association between risk factors for carotid atherosclerosis such as diabetes, hyperlipidemia, hypertension, obesity and smoking .
