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.
一名83岁女性因胸痛和呼吸困难被送往急诊科。胸部X线检查显示左肺气胸。冠状动脉造影显示动脉正常。左心室造影显示心尖运动不能和基底运动增强的协同失调。在18天内,未经任何特殊治疗,协同失调有所改善。在本病例中,左心室功能障碍可能是由气胸导致的儿茶酚胺动力学改变引起的。
