概括
平均左心房过渡时间 (LATT) 预测左心室末端透气压 (LVEDP) 并与不良结果相关. 升高的LATT表明LVEDP更高,增加心力衰竭和死亡风险.
科学领域:
- 心脏病学 心脏病学
- 医疗成像医学成像
- 生物标志物 生物标志物
背景情况:
- 左心房过渡时间 (LATT) 与左心室末端透气压 (LVEDP) 相对应.
- 升高的LVEDP与不良的临床结果和特定的生物标志物有关.
- 非侵入性评估LVEDP在临床上具有意义.
研究的目的:
- 研究长期LATT和LVEDP升高的生物标志物之间的关系.
- 为了确定LATT衍生的LVEDP是否预测不良心血管结果.
- 验证LATT作为LVEDP的非侵入性措施.
主要方法:

- 动态对比的心血管磁共振 (CMR) 用于评估LATT和预测LVEDP (pLVEDP).
- 与侵入性LVEDP的相关性和生物标志物的评估 (NT-proBNP,LA储菌株,LV纵向菌株).
主要成果:
- pLVEDP与侵入性LVEDP有很强的相关性 (r=0.83).
- 增加的pLVEDP与较高的NT-proBNP,较低的LA储菌株和较低的LV纵向菌株有关.
- 升高的pLVEDP是复合结果 (心力衰竭住院或死亡) 的独立预测因子,中度和严重升高的HR分别为2.10和4.33.
结论:
- 来自LATT的pLVEDP准确地反映了侵入性的LVEDP.
- 拉特是一种有价值的非侵入性工具,用于评估LVEDP和相关生物标志物.
- 通过LATT识别的LVEDP升高意味着对心血管不良事件的长期风险很大.

Aortic Regurgitation II: Clinical Features and Diagnostic Tests
383
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Mitral Regurgitation I: Introduction
392
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

Mitral Stenosis II: Clinical features and Diagnostic Tests
201
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

Mitral Stenosis I: Introduction
420
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...
