获得性免疫缺陷综合征(AIDS)系人类嗜T淋巴细胞病毒Ⅲ型/淋巴结病相关病毒感染引起的免疫缺陷。除可产生Kaposi氏肉瘤外,常发生致命性机会性感染,导致多器官系统进行性功能障碍。肺、胃肠道和神经系统是主要受累脏器,心脏亦是多器官受累的一部分。但早期的尸检研究,未能提供具有临床意义的心脏受累表现。晚近,由于AIDS的早期诊断和积极治疗,患者存活期延长,加之超声心动图的应用,心血 Acquired immunodeficiency syndrome (AIDS) is an immunodeficiency disorder caused by infection with human T-lymphotropic virus type III / lymphadenopathy. In addition to producing Kaposi’s sarcoma, fatal opportunistic infections often occur, leading to multiple organ system dysfunction. The lungs, gastrointestinal tract and nervous system are the main organs involved, and the heart is also a part of multiple organ involvement. However, early autopsy studies failed to provide clinically significant signs of cardiac involvement. Recently, due to the early diagnosis and aggressive treatment of AIDS, patients with prolonged survival, combined with the application of echocardiography, effort
