肾素血管紧张素系统(RAAS)长期的过度激活在心力衰竭(简称心衰)的病理生理机制中扮演着重要的角色,阻断 RAAS 的药物目前已然成为了心衰治疗的基石。血管紧张素Ⅱ(Ang-Ⅱ)具有强大的血管收缩及促进心肌细胞发生肥大、纤维化的作用,过多的Ang-Ⅱ与很多心血管疾病相关,血管紧张素酶抑制剂(ACEI)及血管紧张素受体拮抗剂(ARB)可以阻断这种作用。心房钠尿肽和B型脑钠肽通过利钠、利尿调节机体的血压系统,舒张血管、抗细胞增殖等作用。双重血管紧张素受体-脑啡肽酶抑制剂在高血压和心衰中的疗效及安全性日益受到重视,奥马曲垃在治疗心衰和高血压中显示出了良好的前景,但是该药口服生物利用度低、血管性水肿发生率高。LCZ-696是由缬沙坦和AHU-377以1∶1的比例组成的复方制剂,在临床试验中展现出了独特的优势。该新型药物有可能改变以往的心衰药物治疗框架。

Based on accumulating evidence that chronic over-activity of the renin-angiotensin-aldosterone system (RAAS) plays a fundamental role in HF pathophysiology, drugs inhibiting key components of the RAAS have become a cornerstone of contemporary drug therapy. For example, angiotensin-converting enzyme inhibitors (ACEI) reduce biosynthesis of angiotensin-Ⅱ (Ang-Ⅱ), one of the strongest vasoconstrictors, pro-hypertrophic and pro-fibrotic hormones in man. Excessive levels of Ang-Ⅱ have been implicated in many cardiovascular diseases, and additional to ACEI, the detrimental actions of Ang-Ⅱ can be abrogated by direct angiotensin receptor blockers (ARB). Importantly the NPs, particularly ANP and BNP, represents the body's own blood pressure lowering system. Besides promoting vasodilation, NPs counteract pathological growth, fibrosis and dysfunction of heart, kidneys, brain and the vasculature. Dual-acting angiotensin receptor neprilysin inhibitors (ARNI) are under scientific scrutiny for the treatment of hypertension and HF. Early dual ARNI agents such as sampatrilat demonstrated promising effect in HF and hypertension but were discontinued because of poor oral bioavailability and increase in prevalence of angioedema. LCZ-696 is a fixed dose combination of valsartan and AHU-377 in a 1∶1 ratio and is the first and most clinically advanced compound in this new class. As well as, the novel therapeutic agents (LCZ696) currently being evaluated which maybe could change our pharmacological framework for HF.
