近年来,随着对心力衰竭的病理生理的研究,特别是在心衰中对血管因素的深入了解,提倡应用血管扩张剂,为心力衰竭的治疗开辟了一条新途径。许多严重充血性心力衰竭得以治疗,特别是使一些过去认为是难治性的心力衰竭,并发于急性心肌梗塞的泵衰竭的预后有所改善。实践证明,血管扩张剂的应用在心力衰竭的治疗中是一重大的发展。本文就关于血管扩张剂在心力衰竭治疗中的应用的一些问题作一综述。一、血管扩张剂治疗心力衰竭的理论基础。 (一)影响心脏功能的因素: 心排出量是由多种因素调节的,其决定因素有: 1.心肌的收缩力。即心脏的收缩功能,与 In recent years, with the pathophysiology of heart failure, especially in the heart failure of vascular factors in-depth understanding of the promotion of the use of vasodilators, for the treatment of heart failure has opened up a new avenue. Many serious congestive heart failure can be treated, in particular, to some previously considered refractory heart failure, complicated by acute myocardial infarction in the prognosis of pump failure has improved. Practice has proved that the application of vasodilators in the treatment of heart failure is a major development. This article reviews some of the questions about the use of vasodilators in the treatment of heart failure. First, the theory of vasodilator treatment of heart failure. (A) of the factors that affect cardiac function: cardiac output is regulated by a variety of factors, the determinants are: 1. Myocardial contractility. The systolic function of the heart, with
