有关充血性心力衰竭方面的临床和基础研究是富有成果的。但对这类日趋衰弱、身患致命疾病的患者而言,公认时有效治疗药物仅限于三种:洋地黄、利尿剂和血管扩张剂。其中后者已被证实可提高充血性心力衰竭病人的生存率。近来提出β—受体阻滞剂可能作为一种新的治疗方法。它不仅可以改善一些充血性心力衰竭病人的症状,而且可以降低死亡率,改善左室机能、改善临床症状,踏车试验证明其运动耐量亦改善,超声心动图及连续的胸部X线检查均提示扩大的心脏在缩小。
Clinical and basic research on congestive heart failure has been fruitful. However, for these debilitating and fatal diseases, there are only three valid treatments available: digitalis, diuretics, and vasodilators. The latter has been shown to improve survival in patients with congestive heart failure. Recently, β-blockers may be proposed as a new treatment. It can not only improve some patients with congestive heart failure symptoms, but also reduce mortality, improve left ventricular function and improve clinical symptoms, treadmill test also showed improved exercise tolerance, echocardiography and continuous chest X-ray examination were prompted The enlarged heart is shrinking.
