概括

用心脚血管指数 (CAVI) 测量的下动脉硬与心房动 (AF) 除后成功的左心房逆转型 (LARR) 有关. 这一发现表明,CAVI可能预测AF患者的LARR结果.

科学领域:

心脏病学心脏病学
血管生物学血管生物学
电子生理学电子生理学

背景情况:

动脉刚性有助于左心房 (LA) 重塑和心房动 (AF).
左心房逆转型 (LARR) 是AF切除后的一个关键结果.
心血管指数 (CAVI) 量化了动脉硬度.

研究的目的:

为了研究术前动脉硬 (CAVI) 和AF切除后的LARR之间的关联.
为了确定CAVI是否可以预测AF和LA扩大的患者在导管切除后成功的LA重塑.

主要方法:

分析了一组333名患有AF和LA扩大,接受AF切除的患者队列.
在手术前测量了CAVI.
LARR被定义为6个月后的LA体积指数≥15%的下降.

主要成果:

与没有LARR的患者相比,获得LARR的患者手术前CAVI显著降低 (7.80 ± 1.22对比8.57 ± 1.09,P < 0.001).
手术前的CAVI与LARR独立相关 (OR,0.60;95%CI,0.46-0.78;P<0.001). 这两种情况均有相关性.
在LARR组中观察到更高的鼻节律维持率.

结论:

在患有AF和LA扩大的患者中,手术前CAVI是导管切除后LA逆重塑的独立预测因素.
降低动脉硬性可能有助于有利的LA改造AF移除后的AF.

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...

Aortic Regurgitation III: Medical Management

Aortic Regurgitation III: Medical Management

Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

Cardiac Catheterization III: Left Heart Catheterization

Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...
