概括
全球纵向应变 (GLS) 和射出分数 (EF) 是乳腺癌患者化疗影响的关键心声学指标. 某些药物可以提供心脏保护,防止化疗引起的心脏损伤.
科学领域:
- 心脏病学 心脏病学
- 在瘤学瘤学.
- 医疗成像医学成像
背景情况:
- 心声学,特别是喷射分数 (EF),对于在化疗期间监测乳腺癌患者至关重要.
- EF的局限性包括操作员的依赖性和对左心室 (LV) 收缩率微妙变化的不敏感性.
- 全球纵向应变 (GLS) 通过斑点跟踪提供比EF更大的灵敏度和稳定性.
研究的目的:
- 评估各种心声回声学参数,用于监测接受化疗的乳腺癌患者.
- 为改善心脏病监测,确定补充性心声回声仪测量.
- 评估化疗对心脏力学和收缩性的影响.
主要方法:
- 在25名乳腺癌患者的纵向心声谱随访 (基线,期间,化疗后).
- 评估常规心声回声和斑点跟踪成像参数 (GLS,心肌工作指数,心房应变,扭曲,EF).
- 手动和自动EF测量方法的比较.
主要成果:
- 15名患者显示GLS显著减少,与EF降低和心脏力学改变相关.
- 稳定的GLS患者经常患有高血压,并服用ACE抑制剂/ARB,这表明心脏保护作用.
- 与其他参数相比,GLS和EF对化疗效应的敏感性更高.

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,...

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...
