概括
巨细胞动脉炎 (GCA) 显著增加大动脉动脉瘤的风险,特别是胸部动脉瘤. GCA患者的视觉症状没有增加大动脉风险,但与较高的动脉狭窄率有关.
科学领域:
- 风湿病学和血管医学
- 炎症性疾病的流行病学
背景情况:
- 巨细胞动脉炎 (GCA) 是一种全身性血管炎,主要影响大和中型动脉.
- 大动脉动脉瘤 (AAs) 和动脉狭窄 (CAS) 是潜在的严重并发症,但它们在GCA患者中的特定风险,特别是视觉症状,需要进一步阐明.
研究的目的:
- 评估被诊断患有巨细胞动脉炎的患者发展大动脉动脉瘤和动脉狭窄的5年风险.
- 为了比较GCA患者与没有视觉症状之间的这些风险.
主要方法:
- 这是一项回顾性队列研究,涉及7,294名活检证明的GCA患者和265,948名来自TrinetX美国协作网络的对照.
- 倾向性得分匹配 (PSM) 用于平衡GCA和对照组之间的基线特征,并在GCA子组内 (有或没有视觉症状).
- 考克斯比例危险模型被用于估计胸腔,胸腔腹腔,腹腔大动脉动脉瘤和动脉狭窄的5年风险的调整危险比 (aHR).
主要成果:
- 与对照组相比,GCA患者出现任何大动脉动脉瘤的5年风险显著增加 (3.59%对1.75%;aHR,1.98),胸部,胸腔腹部和腹部类型的风险增加.
- 在GCA患者中,动脉狭窄的5年风险也较高 (7.20%与4.37%相比;aHR,1.59).
- 在GCA患者中,视觉症状没有显著改变大动脉动脉瘤的风险 (aHR,1.14) 但与较高的动脉狭窄发生率有关 (aHR,1.24).
结论:
- 巨细胞动脉炎与发展大动脉动脉瘤,特别是胸前大动脉动脉瘤的风险大幅增加有关.
- 虽然GCA中的视觉症状似乎不会增加大动脉动脉瘤的风险,但它们与患上动脉狭窄症的可能性更大有关.

The Arch of Aorta
598
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

Arteries of the Head and Neck
1.1K
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Disorders of the Autonomic Nervous System
586
The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.
