Cirrhotic cardiomyopathy has been defined as a chronic cardiac dysfunction in patients with cirrhosis characterized by impaired contractile responsiveness to stress and/or altered diastolic relaxation with electrophysiological abnormalities in the absence of other known cardiac disease. Non-invasive cardiovascular imaging modalities play a major role in unmasking systolic and diastolic dysfunction in patients with cirrhosis. Echocardiography has been the most commonly used modality for assessing myocardial function in these patients. Conventional echocardiographic indices rely on several assumptions that may limit their applicability in patients with a hyperdynamic circulation. Newer imaging modalities may contribute to a more accurate diagnosis of cardiovascular abnormalities in cirrhotic patients, thereby influencing clinical management. We aimed to review the different non-invasive imaging technologies currently used for assessing left ventricular systolic and diastolic function in cirrhosis, as well as to describe new imaging modalities with potential clinical applicability in the near future.
肝硬化性心肌病被定义为肝硬化患者的一种慢性心脏功能障碍,其特征为在无其他已知心脏疾病的情况下,对应激的收缩反应性受损和/或舒张期松弛改变以及电生理异常。非侵入性心血管成像方式在揭示肝硬化患者的收缩和舒张功能障碍方面发挥着重要作用。超声心动图一直是评估这些患者心肌功能最常用的方式。传统超声心动图指标依赖于几个假设,这可能会限制它们在高动力循环患者中的适用性。更新的成像方式可能有助于更准确地诊断肝硬化患者的心血管异常,从而影响临床管理。我们旨在综述目前用于评估肝硬化患者左心室收缩和舒张功能的不同非侵入性成像技术,并描述在不久的将来具有潜在临床适用性的新成像方式。
