本文报导静脉滴注黄芪(每天20克)治疗病毒性心肌炎心功能减退患者的疗效观察。用型和二维超声心动图估价心功能指标,动态观察慢性心肌炎病情反应情况。结果证明黄芪能显著提高患者左室收缩功能,心排出量增加20%,心功能由平均Ⅱ～Ⅲ级改善为Ⅰ～Ⅱ级;慢性心肌炎治疗前后患感冒次数、心电图异常率差异显著(P<0.001)。而能量合剂组无上述作用。 This article reports the efficacy of intravenous infusion of astragalus (20 grams per day) in the treatment of patients with viral myocarditis in patients with hypothyroidism. Use type and two-dimensional echocardiography evaluation of cardiac function indicators, dynamic observation of chronic myocarditis disease response. The results showed that astragalus significantly increased left ventricular systolic function in patients with cardiac output increased by 20%, heart function improved from average Ⅱ ~ Ⅲ grade Ⅰ ~ Ⅱ grade; before and after treatment of chronic myocarditis, the frequency of cold, ECG abnormalities significantly different (P < 0.001). The energy mixture did not have the above effects.
