Abstract

Aim: Recent research has demonstrated that the contractile characteristics of the right ventricular outflow tract (RVOT) play a significant role in right ventricular function. Pulmonary annular motion velocity (PAMVUT) is a reliable marker of RVOT function. Also, combined systolic velocity [PAMVUT added to tricuspid annular systolic velocity (St)] has been revealed as a suitable parameter for right ventricular systolic function. In this study, we examined the association between the severity of the illness in cirrhotic patients and the combined S velocities (CSV).

Methods: Seventy-four patients with cirrhosis went to the echocardiography laboratory of the Cardiology Department in our centre. Traditional echocardiographic measurements, PAMVUT and CSV values were recorded. The Child-Pugh classes of the patients were determined.

Results: Receiver operating characteristic curve analysis demonstrated that a CSV of 23 cm/s constituted the cut-off value for predicting a moderate-to-severe form of cirrhosis with 76% sensitivity and 65.3% specificity (area uder the curve = 0.735, p < 0.001).

Conclusion: CSV values could predict the severity of cirrhosis more precisely than traditional right ventricular systolic function parameters.

使用组织多普勒成像的联合收缩速度可以预测肝硬化的严重程度：一项前瞻性队列研究。

目的：最近的研究表明，右心室流出道（RVOT）的收缩特性在右心室功能中起着重要作用。肺环形运动速度（PAMVUT）是RVOT功能的可靠指标。此外，联合收缩速度[PAMVUT加三尖瓣环收缩速度（St）]已被揭示为右心室收缩功能的合适参数。在这项研究中，我们检查了肝硬化患者的疾病严重程度与合并S速度（CSV）之间的关系。方法：74名肝硬化患者前往我们中心心内科的超声心动图实验室。记录传统超声心动图测量、PAMVUT和CSV值。确定了患者的Child-Pugh分级。结果：受试者操作特征曲线分析表明，23 cm/s的CSV是预测中度至重度肝硬化的临界值，敏感性为76%，特异性为65.3%（曲线面积=0.735，p＜0.001）。结论：CSV值比传统的右心室收缩功能更准确地预测肝硬化的严重程度参数。
