Carotid artery measurements are considered by experts to be an indicator for arterial plaque and hardening throughout the body. 专家认为颈动脉的测量数据是动脉斑块和周身硬化的指示标志。
Thickening of arterial walls is a precursor to the buildup of plaque, called atherosclerosis, that can lead to heart attacks and strokes. 动脉壁增厚是动脉斑块积聚(既所说的动脉硬化)的一个预测指标,后者可引起心肌梗死与休克。
A stent is essentially a small piece of metal "scaffolding" that pushes arterial plaque to the side and provides a framework to keep the blood vessel open so that the blood can flow freely through it. 支架即是一小片金属网架,可以推移动脉内的斑块、提供保持血管开放的支撑结构,从而使血流自由通畅。
Methods Intima-media thickness of carotid arterial, carotid atherosclerosis plaque score and degree of stenosis are measured in both infarction groups ( 200 cases) and control group ( 200 cases). 方法以200例脑梗死组及200例非脑血管病组为研究对象,检测颈动脉内膜-中膜厚度、颈动脉粥样硬化斑块、颈动脉狭窄程度;
Objective To analyse the corelation of bone mineral density and coronary artery calcification score, carotid arterial intima-media thickness, plaque, and to explore the relationship between osteoporosis and arteriosclerosis in elderly patients. 目的通过对骨密度与冠状动脉钙化积分、颈动脉内中膜厚度及斑块关系的分析,探讨骨质疏松与动脉硬化的关系。
In part ⅰ of this review, we discussed the two major types of calcification in arterial calcification of the media tunica layer and calcification within subdomains of atherosclerotic plaque within the intimal layer of the artery and the similarities and differences between the two types of calcification. 在本综述的第一部分已讨论了两种类型的动脉钙化,动脉粥样硬化斑块的中层钙化和内膜钙化以及两种钙化的相同和不同之处。
Relationship between coronary arterial remodeling and plaque composition assessed by intravascular ultrasound imaging 血管内超声分析斑块组成与冠状动脉重构之间的关系
Platelet 、 fibrinogen and thrombin plays a key role in the process of angioplasty 、 rupture of arterial atheromatous plaque or other factors resulting in injury of the wall of blood vessel. 在由于血管成形术或动脉粥样斑块破裂及其它损伤因素所致血管壁损伤而引起的血栓形成过程中,血小板、纤维蛋白原和凝血酶起着非常关键的作用。
Results of carotid ultrasound in 7 patients showed that the carotid arterial tunica media significantly thickened, that the size and rank of carotid atheromatous plaque was significantly increased, and that carotid stenosis extent deteriorated. 超声波检查发现7例病人颈动脉内中膜增厚、动脉粥样斑块增多增大,管腔进一步狭窄。
Conclusions Coronary arterial remodeling pattern is related to the clinical manifestation and the composition of plaque. Lesions presented with positive remodeling have a higher prevalence of soft plaque and less calcification. 结论冠状动脉重构与临床表现及斑块组成有关,正性重构病变软斑块较多见且钙化较少。
Results The coronary artery calcification score, total calcification score, carotid arterial intima-media thickness and the incidence of plaque of group A were significantly higher than those of group B ( P < 0.01). 结果A组患者的冠状动脉各分支钙化积分及冠状动脉总钙化积分、颈动脉内中膜厚度、颈动脉多发性硬斑发生率高于B组(P<0.01)。
Progress in research on arterial atherosclerotic plaque rupture 动脉粥样斑块破裂的研究进展
In addition to the vessel wall itself, the coupled model of coronary stent and the arterial wall also contain plaque model and stent model. 冠脉支架和动脉壁的耦合模型除了血管壁本身外,还含有斑块和支架的模型。
Obviously, the ABI exercise test can detect not only the existence of a large lower extremity arterial plaque ( area 20mm2), but also the increased arterial stiffness, these population should be strengthened to improve the arterial elasticity. 4. 可见,PAD高危人群进行ABI运动实验,不仅能够检测出下肢动脉存在大粥样硬化斑块(面积20mm2)的人群,而且可以检测出动脉硬度增高,需加强改善动脉弹性治疗的人群。
ER β play an important role in many aspects such as regulate lipid metabolism, anti-oxidative stress injury, improve endothelial function, inhibit the formation of arterial plaque, modulate relaxation and contraction of blood vessels and reduce cardiac ischemia-reperfusion injury. ERp在调节血脂代谢、抗氧化应激损伤、改善血管内皮功能、抑制动脉粥样斑块形成、舒缩血管、减少心脏缺血再灌注损伤等方面起重要作用。
Many researches confirm that lower blood lipids can improve the function of endothelial tissue, reduce arterial plaque, thrombosis, and cardiovascular morbidity. 大量研究证实,降低血脂可以改善血管内皮功能,减缓动脉粥样硬化斑块的破裂,降低心脑血管疾病的发病率。
Acute myocardial infarction ( AMI) is directly caused by coronary arterial thrombosis on the base of atherosclerotic plaque ruptures or fissures. 急性心肌梗死(AMI)是心脏自身供血动脉-冠状动脉在粥样硬化基础上继发了血栓形成引起急性闭塞所致。
It is now clear, macrophage transformation into foam cells, arterial endothelial dysfunction and vascular smooth muscle proliferation in atherosclerosis initiation, development through the process of plaque rupture plays an important role. 现在已经清楚,巨噬细胞向泡沫细胞的转化、动脉内皮损伤以及血管平滑肌增生在动脉粥样硬化的起始、发展直到斑块破裂过程中扮演重要角色。
