Friedreich氏共济失调症(FA)是1863年由Friedreich首先报告的以脊髓运动失调为主的进行性遗传性疾病,可合并心脏损害、骨骼异常(脊柱侧弯、弓形足)及糖尿病等,特别是心脏受损对FA的预后影响很大。本文对FA的心脏合并症进行概述 FA的心脏合并症的临床表现:Harding(1983)对115例FA患者的心脏损害进行研究发现:有劳动时呼吸困难(40.0％)、心悸(11.3％),心绞痛(3.5％),下肢发绀(46.1％),浮肿(7.8％),心脏闻及Ⅲ心音(6.9％),Ⅳ心音(5.2％),心脏杂音(10.4％)等。75.4％的病例心电图异常,T波异常 Friedreich’s ataxia (FA) was the first progressive genetic disease reported by Friedreich in 1863 to be characterized by spinal dyskinesia. It may be associated with heart damage, skeletal abnormalities (scoliosis, arch foot) and diabetes, in particular The impaired heart has a great effect on the prognosis of FA. This article presents the clinical manifestations of cardiac complications in patients with FA. Harding (1983) studied cardiac damage in 115 patients with FA and found difficulty breathing (40.0%), palpitations (11.3%), (3.5%), cyanotic lower limbs (46.1%), edema (7.8%), heart smell and Ⅲ heart sound (6.9%), Ⅳ heart sound (5.2%) and heart murmur (10.4%). 75.4% of the cases of abnormal ECG, T wave abnormalities
