高血压可造成动脉内膜机械性损伤,使血脂易在动脉壁沉积,形成脂肪斑块并造成动脉硬化狭窄。糖尿病又使脂肪代谢出现异常,血液中运送脂蛋白过程中脂肪容易沉积在血管内壁形成脂肪斑块。高血压合并糖尿病则更容易发生血管退行性病变而促使动脉硬化。颈动脉彩超能够了解血管的结构 Hypertension can cause mechanical damage to the intima of the arteries, which tends to deposit blood lipids in the arterial wall, forming fat plaque and causing stenosis of atherosclerosis. Diabetes also makes abnormal fat metabolism, blood lipids in the process of transporting lipids easily deposited in the blood vessel wall to form fat plaque. Hypertension with diabetes is more prone to vascular degenerative lesions and promote atherosclerosis. Carotid ultrasound can understand the structure of blood vessels
