概括
硬化症患者的数字与动脉血流的显著变化和动脉样硬化的增加有关. 这表明数字可能表明超出微血管损伤的更广泛的血管问题.
科学领域:
- 血管医学
- 关节病学
- 心血管成像
背景情况:
- 数字 (DUs) 是系统性硬化症 (SSc) 的严重血管并发症,通常归因于微血管损伤.
- 新出现的证据表明大血管异常,包括亚临床动脉样硬化和血液动力学变化,是导致SSc的潜在原因.
研究的目的:
- 在SSc患者中研究历史的DU与大血管干扰之间的关联.
- 分析动脉和脊椎多普勒超声波的发现,重点是血液动力学指数 (最大静脉缩速度,末端静脉缩速度,阻力指数) 和内心介质厚度.
主要方法:
- 一项涉及107名SSc患者的横截面研究.
- 收集临床,血清,心血管和代谢数据.
- 用于评估血液动力学参数和内脏介质厚度的冠状动脉脊椎多普勒超声波,患者根据DU病史分层.
主要成果:
- 患有DU病史的SSc患者在内动脉 (ICA) 和外动脉中显示出显著更高的动脉峰值 (PSV).
- 在DU组中观察到右侧ACA的抗性指数 (RI) 升高,以及动脉斑块的患病率更高.
- 经历过低氧化碳的患者独立预测了ICAPSV的增加和动脉斑块的存在.
结论:
- 在SSc有数字的病史与动脉血动力学异常和亚临床动脉样硬化的更大负担有关.
- 这些发现表明,除了微血管损伤外,DU也可能意味着潜在的宏血管功能障碍.
- 建议SSC患者采用综合血管评估方法,以解决微血管和宏血管并发症.

01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
34
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

38
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)...

01:27Assessment of the Cardiovascular System III: Palpation
492
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...

01:29Assessment of the Cardiovascular System II: Inspection
405
Inspection is the initial step in assessing the cardiovascular system. It involves a detailed visual examination that provides crucial information about a patient's circulatory and cardiac health. This systematic process, conducted from head to toe, helps identify signs of cardiovascular conditions by observing physical appearance, skin and mucous membranes, jugular and carotid pulsations, chest symmetry, and the condition of the extremities.

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
