概括
心血管疾病是ANCA相关血管炎 (AAV) 的一个主要风险. 许多AAV患者的冠状动脉 (CAC) 评分显著,表明心血管疾病风险高,但他类药物的使用不一致.
科学领域:
- 心脏病学 心脏病学
- 类风湿病学 类风湿病学
- 放射学 放射学是指放射学
背景情况:
- 心血管疾病 (CVD) 是ANCA相关血管炎 (AAV) 的主要死亡原因.
- 积极查和初级心血管疾病预防策略对于改善AAV患者的治疗结果至关重要.
- 在CT扫描上冠状动脉 (CAC) 评分可以量化心血管疾病风险.
研究的目的:
- 评估ANCA相关血管炎 (AAV) 患者冠状动脉 (CAC) 的患病率和程度.
- 为了比较骨髓氧化酶-ANCA (MPO-ANCA) 和蛋白酶3-ANCA (PR3-ANCA) 阳性AAV患者之间的CAC负担.
- 评估在有显著CAC的AAV患者中使用他类药物治疗及其与主要心脏不良事件 (MACE) 的关联.
主要方法:
- 对175名来自Mass General Brigham AAV队列 (2002-2019) 的AAV患者进行了回顾性分析,并提供胸部CT扫描.
- 冠状动脉 (CAC) 评分和年龄,性别和种族标准化的CAC百分位数的计算.
- 量子回归用于比较ANCA类型的CAC;基于CAC分数的MACE差异格雷测试.
主要成果:
- 大多数患者 (65/175,39%) 的CAC得分≥100,表明临床显著的冠状动脉样硬化.
- 与PR3-ANCA阳性患者 (p<0.05) 相比,MPO-ANCA阳性AAV患者的中位数CAC得分 (24比1) 和百分位数 (50比34) 较高.
- 只有25% (29/116) 的非零CAC得分的患者被处方他类药物;更高的CAC得分趋向于增加MACE风险 (p=0.16).
结论:
- 在AAV人群中,临床意义上的冠状动脉是普遍存在的.
- 在MPO-ANCA和PR3-ANCA亚型之间存在CAC负担的差异.
- 在高CAC的AAV患者中,用于预防心血管疾病的不一致的他类药物使用,需要进一步调查CT引导查策略.

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
