Cardiac vascular dysfunction was described years ago in alcohol-associated liver cirrhosis and recently became known as cirrhotic cardiomyopathy (CCM) in 2005. Cirrhotic cardiomyopathy is a specific cardiac dysfunction estimated to be prevalent in half of the liver cirrhosis patient population; it comprises a triad of impaired myocardial contractile responses to stress (systolic dysfunction), inadequate ventricular relaxation, and electrophysiological abnormalities. This review describes the various pathophysiological mechanisms connecting liver cirrhosis to the alterations seen in CCM and briefly mentions the role of the cardiovascular system in connecting the pathophysiology of hepatorenal syndrome (HRS). Insertion of the transjugular intrahepatic portosystemic shunt (TIPS) and liver transplantation exacerbates the underlying cardiac dysfunction leading to signs and symptoms of heart failure. This article also focuses on the clinical importance of diagnosing CCM and the limitations existing around traditional diagnostic criteria based on transmitral flow parameters. It highlights newer parameters proposed by the Cirrhotic Cardiomyopathy Consortium to obtain a diagnosis of CCM. Liver transplantation is the only treatment available to cure CCM.
心脏血管功能障碍在多年前就已在酒精性肝硬化中被描述,2005年它作为肝硬化性心肌病(CCM)被人们所熟知。肝硬化性心肌病是一种特殊的心脏功能障碍,据估计在一半的肝硬化患者中普遍存在;它包括心肌对应激的收缩反应受损(收缩功能障碍)、心室舒张不足和电生理异常这一组三联征。这篇综述描述了将肝硬化与在CCM中所见改变相联系的各种病理生理机制,并简要提及了心血管系统在肝肾综合征(HRS)病理生理联系中的作用。经颈静脉肝内门体分流术(TIPS)和肝移植会加重潜在的心脏功能障碍,导致心力衰竭的体征和症状。本文还重点关注了诊断CCM的临床重要性以及基于二尖瓣血流参数的传统诊断标准存在的局限性。它强调了肝硬化性心肌病协会提出的用于诊断CCM的更新参数。肝移植是治愈CCM的唯一可用治疗方法。
