充血性心衰(甚至由不能治愈的心衰)心血管疾病引起的常常是可逆的。心衰症状出现后,经过适当处理的病人可以有十年愉快活动自如的生活。对于充血性心衰最重要的治疗方法是用洋地黄。在因饮食、利尿剂以及限制活动需要补充洋地黄以前,洋地黄常常要足量一个长时期。对内科医生来说恰当地使用洋地黄是一个普通和重要的要求。洋地黄对于给药者来说是一种棘手的药物。治疗量和中毒量之间的差距是小的,在大多数病人当中,没有最适当剂量的可靠指征。毒性常常可以遇到,因此详述洋地黄的作用就变得相当重要了。 Congestive heart failure (even by incurable heart failure) is often reversible due to cardiovascular disease. After symptoms of heart failure appear, properly treated patients can have a happy and comfortable life for ten years. The most important treatment for congestive heart failure is digitalis. Digitalis usually lasts long enough before it can be supplemented with digitalis because of diet, diuretics, and restricted activities. The proper use of digitalis for physicians is a common and important requirement. Digitalis is a daunting drug for the donor. The difference between treatment and poisoning is small, and in most patients there is no reliable indication of the most appropriate dose. Toxicity can often be encountered, so it is important to detail the effect of digitalis.
