概括
不确定来源的栓塞性中风 (ESUS) 患者表现出显著的冠状动脉样硬化,特别是年轻人. 冠状动脉 (CAC) 评分可以改善中风分类和预防策略.
科学领域:
- 心脏病学 心脏病学
- 神经学 神经学
- 放射学 放射学是一门学科.
背景情况:
- 源不明的栓塞性中风 (ESUS) 是一种没有明确原因的中风亚型,经验性抗凝疗显示出有限的成功.
- 亚临床动脉样硬化是ESUS的潜在贡献者,但其在这些患者中的程度尚不清楚.
- 冠状动脉 (CAC) 评分是动脉样硬化的关键指标.
研究的目的:
- 通过使用CAC评分来调查ESUS患者冠状动脉样硬化的负担.
- 探索CAC负担与患者人口统计学,特别是年龄之间的关系.
主要方法:
- 一项回顾性队列研究包括165名ESUS患者,他们接受了心脏CT血管造影 (CCTA).
- 使用Agatston方法计算CAC得分,并与MESA数据库百分位数进行比较.
- 之前接受过冠状动脉干预的患者被排除在外.
主要成果:
- 与人口规范相比,ESUS患者的中位数CAC得分和百分位数显著更高.
- 一个值得注意的发现是,65岁或更年轻的患者的CAC百分位数更高.
- 尽管CAC得分相似,但年轻患者与年龄组相比,动脉样硬化负担更大.
结论:
- 在ESUS患者中,冠状动脉样硬化的负担很大.
- 在ESUS中CAC升高可能表明更广泛的心血管风险,并提供有关中风机制的见解.
- CAC评估可以完善病因诊断,并为ESUS指导个性化二次预防.

Pulmonary Embolism I: Introduction
696
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Coronary Circulation
7.2K
The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

Pulmonary Embolism III: Nursing Management
436
A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

Sinusoidal Sources
1.2K
Direct current (DC) refers to an electric current that flows in a single direction, maintaining a constant polarity. This is in contrast to alternating current (AC), which periodically changes its direction and magnitude. AC forms the backbone of modern electricity transmission and distribution systems due to its efficient long-distance transmission capabilities.
In homes, the power supplies use sinusoidal sources to provide electricity. These sources generate a voltage that varies sinusoidally...

AC Sources
4.1K
Direct current is a flow of electric charge in only one direction and has a steady state of constant voltage in the circuit. Rectifiers, batteries, commutator-equipped generators, and fuel cells are some examples of devices that generate direct current. Nowadays, most applications use a time-varying voltage source. Alternating current is a flow of electric charge that periodically reverses direction. An alternating current is produced by an alternating emf that is generated in a power plant. If...

Sources of Law

Laws form the essential rules set by governing authorities to shape and control societal behavior. In nursing, laws guide actions, safeguard patient rights, define nurses' scope of practice, and maintain professional standards. Understanding the legal framework governing nursing involves recognizing four primary sources of law: constitutional, statutory, administrative (regulatory), and common law.
Constitutional law is foundational, deriving from federal and state constitutions, and...
