Alcoholic liver disease is the most prevalent cause of progressive liver disease in Europe. Alcoholic cirrhosis occurs in 8%-20% of cases of alcoholic liver disease. It has significant influence on cardiovascular system and haemodynamics through increased heart rate, cardiac output, decreased systemic vascular resistance, arterial pressure and plasma volume expansion. Cirrhotic cardiomyopathy is characterised by systolic and diastolic dysfunction and electrophysiological abnormalities, if no other underlying cardiac disease is present. It is often unmasked only during pharmacological or physiological stress, when compensatory mechanisms of the heart become insufficient to maintain adequate cardiac output. Low-to-moderate intake of alcohol can be cardioprotective. However, heavy drinking is associated with an increased risk of cardiovascular diseases, such as alcoholic cardiomyopathy, arterial hypertension, atrial arrhythmias as well as haemorrhagic and ischaemic stroke. Alcoholic cardiomyopathy is characterised by dilated left ventricle (LV), increased LV mass, normal or reduced LV wall thickness and systolic dysfunction.
酒精性肝病是欧洲进行性肝病最常见的病因。酒精性肝硬化发生于8%-20%的酒精性肝病病例中。它通过增加心率、心输出量、降低全身血管阻力、动脉压和血浆容量扩张,对心血管系统和血流动力学产生重大影响。如果不存在其他潜在的心脏疾病,肝硬化性心肌病的特征是收缩和舒张功能障碍以及电生理异常。它通常仅在药物或生理应激期间才会显现出来,此时心脏的代偿机制不足以维持足够的心输出量。低至中度饮酒可能具有心脏保护作用。然而,大量饮酒与心血管疾病风险增加有关,如酒精性心肌病、动脉高血压、房性心律失常以及出血性和缺血性中风。酒精性心肌病的特征是左心室扩张、左心室质量增加、左心室壁厚度正常或降低以及收缩功能障碍。
