概括
在败血症中,右心室功能障碍 (RVD) 可以通过组织运动环状位移 (RVTMAD) 来准确诊断,该方法来自斑点跟踪心声学 (STE). RVTMAD提供了有价值的预后信息,并补充了传统的心声回声学方法.
科学领域:
- 心脏病学 心脏病学
- 关键护理医学 关键护理医学
- 心声回声图 (Echocardiography) 是一种心声回声图.
背景情况:
- 右心室功能障碍 (RVD) 是败血症的显著预后因素.
- 诊断准确性和STE衍生参数的预后值,如RVLS和RVTMAD在败血症中,尚未得到很好的定义.
研究的目的:
- 评估在重症败血症患者中RVD的STE衍生的RVLS和RVTMAD的诊断性能.
- 评估这些参数对死亡率的预后价值.
主要方法:
- 对159名患有败血症或败血性休克的ICU患者进行了回顾性观察研究.
- 通过胸腔回声心脏图与RVLS和RVTMAD的线下STE分析.
- 对诊断性能的ROC曲线分析和死亡率相关性的Cox回归.
主要成果:
- 57%的患者患有RVD. RVTMADmid和RVTMAD%的诊断准确度很高 (AUROC为0.913-0.917). 这两种诊断方法均具有较高的准确度.
- 特定的RVTMAD切线 (<10.95毫米或<16.70%) 预测了更高的住院死亡率.
- 索法得分是医院死亡率的唯一独立预测指标.
结论:
- RVTMAD是一种简单,可重复的STE参数,具有在败血症中RVD的优异诊断性能.
- RVTMAD可以补充传统的心声回声学,尤其是低于最佳的图像质量.

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...

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...
