儿童喘会影响心脏功能,显示心室和右心房的静缩和静缩性能下降. 高级心声回声学 (2D-STE) 可以检测到这些早期变化,特别是在中度至重度的病例中.
科学领域:
- 儿童心脏病学 儿童心脏病学
- 心血管成像 - 心血管成像
- 呼吸系统医学 呼吸系统医学
背景情况:
- 儿童喘对心脏的长期影响尚不清楚.
- 喘的严重程度可能会随着时间的推移影响心脏功能.
研究的目的:
- 评估儿科患者中喘严重程度与心脏功能之间的关系.
- 通过先进的心声回声技术,识别早期的心脏变化.
主要方法:
- 评估了113名儿科喘患者 (10-18岁) 和59名健康对照.
- 使用心电图,常规心声图,组织多普勒成像 (TDI) 和2D斑点跟踪心声图 (2D-STE) 评估心脏功能.
- 喘患者被分为轻度和中度至重度的组.
主要成果:
- 喘患者表现出右心室面积 (RVA) 的增加和心室间隔膜 (IVSS') 和左心室S'速度 (LVS') 的减少,以及右心室晚期透气速度 (RVA').
- 在喘患者中,2D-STE揭示了左下心室全球纵向/周围应变 (LVGLS,LVGCS),右心室全球纵向应变 (RVGLS) 和右心房储应变 (RARS).
- 在喘患者中观察到较高的菌株率 (LVGLSR,LVGCSR,RVGLSR,RARSR),中度至重症组的变化更为显著.
结论:
- 儿童喘与心室和右心房的缩和放缩功能受损有关.
- 喘的严重程度与心脏功能障碍的程度相关.
- 2D-STE是检测儿科喘患者早期心脏变化的宝贵工具.

Imaging Studies for Cardiovascular System III: X-Ray
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...
