一名83岁妇女以胸痛和呼吸困难就诊于急诊科。胸片显示左肺气胸。冠状动脉造影显示动脉正常。左心室造影显示顶端运动和底部运动不同步。在18天内，在没有任何特殊处理的情况下，无能性得到改善。在本病例中，左心室功能障碍可能是由于气胸引起的儿茶酚胺动力学改变引起的。
An 83 year old woman presented to the emergency department with chest pain and dyspnoea. Chest radiography showed pneumothorax of the left lung. Arteries were normal on coronary angiography. Left ventriculography showed asynergy of apical akinesis and basal hyperkinesis. Within 18 days, the asynergy improved without any specific treatment. In the present case the left ventricular dysfunction may have been induced by altered catecholamine dynamics as a result of pneumothorax.
