目的 探讨重症肌无力 (MG)患者的心脏损害。方法 对 1 0 3例MG患者空腹取血查心肌酶 ,心电图检查。结果 1 0 3例MG患者中心肌酶异常率 2 6 2 % (2 7/ 1 0 3) ,心电图异常率 2 3 3 % (2 4 / 1 0 3)。伴胸腺瘤的MG患者与不伴胸腺瘤的MG患者之间的心肌酶异常率及心电图异常率均有显著性差异 (P <0 0 5)。眼肌型患者与全身型患者之间的心肌酶异常率及心电图异常率均无显著性差异 (P >0 0 5)。结论 MG患者伴有心脏损害 ,尤其伴胸腺瘤的MG患者。心肌酶及心电图检查可提示MG患者的心脏损害。
Objective To investigate the cardiac damage in patients with myasthenia gravis (MG). Methods One hundred and thirty cases of MG patients underwent fasting blood test for myocardial enzymes, ECG. Results The abnormal rate of myocardial enzymes in 263 MG patients was 26.2% (27/103), and the abnormal rate of ECG was 23.3% (24/103). There was a significant difference in the abnormal rate of myocardial enzymes and abnormal ECG between MG patients with thymoma and MG patients without thymoma (P <0.05). There was no significant difference in the rate of abnormal myocardial enzymes and ECG abnormalities between oculomotor patients and general patients (P> 0.05). Conclusion MG patients with heart damage, especially with thymoma MG patients. Myocardial enzymes and electrocardiography can prompt cardiac damage in MG patients.
