概括
肺部受损的康复COVID-19患者显示右心室 (RV) 和左心室 (LV) 功能下降. 传统的心声回声学可能会忽略这些微妙的障碍,突出了需要先进的技术,如2D STE.
科学领域:
- 心脏病学 心脏病学
- 肺部病理学 肺部病理学
- 医疗成像医学成像
背景情况:
- 胸外回声心电图 (TTE) 是评估右心室 (RV) 功能的标准.
- 传统的TTE参数在检测早期RV缩功能障碍方面存在局限性.
- 二维斑点跟踪回声心电图 (2D STE) 对于检测亚临床心脏功能障碍非常有价值.
研究的目的:
- 调查在COVID-19幸存者之前肺部参与的RV功能潜在的长期影响.
- 评估从中度COVID-19中恢复后是否存在微妙的RV功能缺陷.
主要方法:
- 预期的观察性队列研究.
- 参与了57名健康对照和54名肺部受影响的康复COVID-19患者.
- 利用了TTE并收集了人口,临床和实验室数据.
主要成果:
- 患者表现出显著的左下心室喷射分数 (LVEF),三环状平面缩外流 (TAPSE) 和分数面积变化 (FAC).
- 在患者组中观察到减少RV自由壁应变 (RV-FWS) 和RV全球纵向应变 (RV-GLS).
- LV全球纵向菌株 (LV-GLS) 和RV纵向菌株 (RV-LS) 也显示下降.
结论:
- 在康复的COVID-19患者中,RV-LS和LV-GLS下降.
- 虽然传统的RV回声心电图参数看起来正常,但TAPSE,St和FAC在患者中较低.
- 亚临床RV和LV功能缺陷可能在COVID-19后持续存在,即使没有ICU入院.

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...

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,...
