概括
穿皮冠状动脉干预 (PCI) 在6个月内改善慢性冠状动脉综合征患者的右心室功能. 然而,在PCI后12个月,RV无壁纵向应变 (RVFWLS) 仍然低于对照组.
科学领域:
- 心脏病学 心脏病学
- 心声回声扫描 (Echocardiography) 是一种心声回声扫描.
- 评估心脏功能的评估
背景情况:
- 慢性冠状动脉综合征会影响心脏功能.
- 穿皮冠状动脉干预 (PCI) 是冠状动脉疾病的常见治疗方法.
- 在PCI后评估右心室 (RV) 功能对于患者的结果至关重要.
研究的目的:
- 评估慢性冠状动脉综合征患者PCI后RV缩功能变化.
- 为了比较患者和健康对照之间的RV功能指标.
- 评估三维斑点跟踪回声心脏学 (3D-STE) 在PCI后监测RV功能的实用性.
主要方法:
- 一项前性研究包括136名为慢性冠状动脉综合征接受PCI的患者和110名健康对照.
- 包括常规和3D-STE在内的心声扫描在PCI后1周,6个月和12个月进行.
- 测量的主要参数包括TAPSE,S',RVFAC,RVFWLS,RVGLS,RVSV和RVEF.
主要成果:
- 在PCI后1周至6个月内,观察到VR功能参数 (TAPSE,S',RVFAC,RVGLS,RVSV,RVEF) 的显著改善.
- 虽然一些参数在6至12个月之间没有显著变化,但TAPSE,S'和RVFWLS继续显著增加.
- 在12个月后,与健康对照组相比,RVFWLS在患者中仍然明显较低,尽管其他RV功能指标没有显著差异.
结论:
- 在慢性冠状动脉综合征患者PCI后,右心室缩功能显著改善.
- 在PCI后,RVFWLS仍然是持续RV功能障碍的潜在指标.
- 3D-STE是一个有价值的非侵入性工具,用于量化RV缩功能在这个患者群体.

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...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
