概括
脑内皮功能障碍,通过受损的臂动脉流介导扩张 (FMD) 表示,与年轻成年人脑内皮内膜介质 (IMT) 加厚有关. 心血管风险因素加剧了这种加厚,这表明内皮功能障碍是动脉样硬化的早期标志物.
科学领域:
- 心血管医学 心血管医学
- 血管生物学 血管生物学
- 公共卫生 公共卫生
背景情况:
- 内皮血管扩张器功能障碍和心动脉内膜介质 (IMT) 加厚是亚临床心血管疾病的关键指标.
- 这些标志物在年轻人中普遍存在,可以预测未来的心血管事件.
研究的目的:
- 在一大群年轻成年人中调查内皮血管扩张器功能障碍和大脑动脉IMT之间的相关性.
- 检查心血管风险因素如何与这些标记物相互作用.
主要方法:
- 在2109名健康成年人 (24-39岁) 中,利用超声波测量手臂动脉流介导扩张 (FMD) 和动脉IMT.
- 分析了 FMD 和 IMT 之间的关联,并调整了共变量.
- 基于口病反应 (受损与增强) 的分层参与者来评估风险因素的影响.
主要成果:
- 在 FMD 和 IMT 之间发现了显著的反向关联 (P<0.001).
- 心血管风险因素的增加与 FMD 反应受损的个体中较高的 IMT 相关联 (P<0.05).
- 没有发现风险因素和IMT之间的显著相关性,在那些有增强的口病响应 (P>0.2) 的人群中.
结论:

Assessment of blood pressure in brachial artery(two-step method)
2.1K
Measuring blood pressure is a fundamental skill in healthcare that aids in diagnosing and monitoring hypertension and other cardiovascular conditions. An aneroid sphygmomanometer, commonly used in clinical settings, offers a manual and precise method for blood pressure measurement. The technique for using this instrument involves specific steps that must be carefully executed to ensure accuracy. The following detailed description outlines a two-step technique for assessing blood pressure using...

Structure of Blood Vessels
12.0K
Blood is circulated throughout the human body through a network of blood vessels called the circulatory system. This system includes arteries that transport blood from the heart to various body parts. These arterial pathways divide into smaller vessels until they reach the arterioles, which further split into capillaries. It is within these minuscule capillaries that the exchange of nutrients and waste products takes place. After this exchange, the blood is collected by venules, which fuse to...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests
961
Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...
