Abstract

Background

The high mortality rate of patients with acute myocardial infarction (AMI) remains the most pressing issue of modern cardiology. Over the past 10 years, there has been no significant reduction in mortality among patients with AMI. It is quite obvious that there is an urgent need to develop fundamentally new drugs for the treatment of AMI. Angiotensin 1–7 has some promise in this regard.

Objective

The objective of this article is analysis of published data on the cardioprotective properties of angiotensin 1–7.

Methods

PubMed, Scopus, Science Direct, and Google Scholar were used to search articles for this study.

Results

Angiotensin 1–7 increases cardiac tolerance to ischemia/reperfusion and mitigates adverse remodeling of the heart. Angiotensin 1–7 can prevent not only ischemic but also reperfusion cardiac injury. The activation of the Mas receptor plays a key role in these effects of angiotensin 1–7. Angiotensin 1–7 alleviates Ca²⁺ overload of cardiomyocytes and reactive oxygen species production in ischemia/reperfusion (I/R) of the myocardium. It is possible that both effects are involved in angiotensin 1–7-triggered cardiac tolerance to I/R. Furthermore, angiotensin 1–7 inhibits apoptosis of cardiomyocytes and stimulates autophagy of cells. There is also indirect evidence suggesting that angiotensin 1–7 inhibits ferroptosis in cardiomyocytes. Moreover, angiotensin 1–7 possesses anti-inflammatory properties, possibly achieved through NF-kB activity inhibition. Phosphoinositide 3-kinase, Akt, and NO synthase are involved in the infarct-reducing effect of angiotensin 1–7. However, the specific end-effector of the cardioprotective impact of angiotensin 1–7 remains unknown.

Conclusion

The molecular nature of the end-effector of the infarct-limiting effect of angiotensin 1–7 has not been elucidated. Perhaps, this end-effector is the sarcolemmal K_ATP channel or the mitochondrial K_ATP channel.

血管紧张素 1-7 增加心脏对缺血/再灌注的耐受性并减轻心脏的不良重塑--信号机制

急性心肌梗死（AMI）患者的高死亡率仍然是现代心脏病学最紧迫的问题。在过去 10 年中，急性心肌梗死患者的死亡率一直没有显著下降。显而易见，治疗急性心肌梗死急需开发全新的药物。在这方面，血管紧张素 1-7 具有一定的前景。
