概括

左心房应变 (LASr) 可以在无症状个体中识别隐性心房动 (AF). 较低的LASr值表明隐性心脏功能障碍的风险更高,有助于AF风险分层.

科学领域:

心脏病学心脏病学
心声回声图 (Echocardiography) 是一种心声回声图.
前庭的研究研究.

背景情况:

隐形心房动 (AF) 是中风的主要危险因素,但在无症状个体中难以检测.
亚临床左心房 (LA) 功能障碍,可通过使用斑点跟踪心声学 (STE) 的心肌张力分析检测,可能表明隐藏的AF.
这项研究评估了LA菌株参数在识别无症状AF的有用性.

研究的目的:

评估左心房 (LA) 应变的诊断价值,通过斑点跟踪回声心脏学 (STE) 测量,在检测无症状隐性心房动 (AF) 的患者正常心电图.
为了比较LA机械功能在无症状的个人与隐藏的AF和健康的志愿者之间.

主要方法:

追溯招募354名受试者,分为健康对照组,隐藏性AF,阳性AF和持久性AF组.
使用STE测量LA机械功能的测量,包括LA储应变 (LASr),LA管道应变 (LAScd) 和LA收缩应变 (LASct).
使用单变量/多变量回归和接收器操作特征 (ROC) 曲线分析诊断性能.

主要成果:

与健康对照组相比,隐性AF患者的LASr,LAScd和LASct显著降低.
即使调整了其他临床和心声学参数之后,LASr与隐性AF有很强的相关性.
在ROC曲线分析中,LASr被确定为一种高效的诊断标记物,截止值为34.1%,具有75.4%的灵敏度和87.6%的特异性.

结论:

左心室储菌株 (LASr) 是在无症状人群中识别隐性AF的一个有价值的工具.
患有LASr值≤34.1%的患者患有隐性心脏功能障碍的风险增加.
这些发现支持使用LASr来改善隐性AF个体的识别和风险分层.

Mitral Stenosis II: Clinical features and Diagnostic Tests

Mitral Stenosis II: Clinical features and Diagnostic Tests

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...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

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...
