概括
在心脏CT扫描中,患急性缺血性中风 (AIS) 患者的高风险心血管栓塞源明显比患中风模仿患者更常见. 这一发现凸显了心脏CT在识别中风原因方面的临床重要性.
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:
- 心脏计算机断层扫描 (CT) 越来越多地用于在急性缺血性中风 (AIS) 中识别心血管血栓源.
- 评估通过心脏CT和AIS检测到的高风险心血管血栓源之间的关联对于中风管理至关重要.
研究的目的:
- 评估心脏CT上发现的高风险心血管血栓源与AIS发生之间的关联.
- 根据心血管栓塞源检测,确定心脏CT在区分AIS与中风模仿 (SMi) 的诊断价值.
主要方法:
- 一项病例控制研究使用了从怀疑中风的成人患者接受心脏CT (2018-2020) 的前性队列数据进行.
- 病例被定义为AIS患者,对照组是SMi患者,暂时性缺血性发作 (TIA) 患者除外.
- 心脏放射科医生使用预定义的标准评估高风险心血管血栓源,用于分析的逻辑回归 (第一个被处罚的可能性),根据年龄,性别和心肌梗塞病史进行调整.
主要成果:
- 在500名纳入的患者中 (375名AIS,125名SMi),在8.5%的AIS患者中发现了高风险的心血管血栓源,而在SMi患者中为0% (aOR 23.8).
- 心脏血栓是最常见的异常,在6.1%的AIS患者中发现,而在SMi患者中没有发现.
- 在初级评估中,分析排除了心房的患者,而二级分析包括了他们.
结论:
- 与SMi患者相比,患有AIS的患者在心脏CT上更频繁地检测到高风险的心血管栓塞源.
- 这些发现强调了在被诊断为缺血性中风的患者中使用急性心脏CT识别心血管栓塞源的临床意义.

1
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...

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...

142
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...

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...
