概括
大多数从COVID-19中恢复过来的患者保持正常的心脏功能,但在诊断后几周的心声图上,超过一半的患者显示左心室全球纵向应变 (GLS) 减少.
科学领域:
- 心脏病学 心脏病学
- 传染性疾病 传染性疾病
- 医疗成像医学成像
背景情况:
- 有限的数据存在于后冠状病毒病 (COVID) 患者的残留心声图发现.
- 需要对后COVID患者的前景表型化,以了解长期的心脏影响.
研究的目的:
- 在COVID-19感染后的患者中,前性评估心声回声学发现,包括菌株分析.
- 在后COVID队列中评估左心室喷射分数 (LVEF) 和全球纵向应变 (GLS).
主要方法:
- 在急性COVID-19后出院的127名患者在诊断后4-18周接受了随访.
- 进行了全面的心声回声,通过3D,2D双飞机辛普森或视觉估计来评估LVEF.
- 使用独立于供应商的2D斑点跟踪软件测量左心室全球纵向应变 (GLS).
主要成果:
- 96%的患者有正常的LVEF,97%的患者有正常的右心室缩功能.
- 53%的队列表现出异常的LV GLS (<18%),表明心肌功能受损.
- 即使在没有先前心脏病的患者中,46%的患者表现出异常的LV GLS,尽管LVEF正常.
结论:
- 大多数COVID后患者在诊断后4-18周表现出正常的LVEF.
- 显著比例的COVID后患者表现出心肌功能受损,由异常的LV GLS证明.
- LV GLS可能是COVID-19感染后亚临床心脏功能障碍的敏感指标.

381
Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...

01:20Imaging Studies for Cardiovascular System II:Types of Echocardiography
304
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...

01:20Imaging Studies for Cardiovascular System III: X-Ray
218
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...
