Abstract

Lyophilized recombinant brain natriuretic peptide (BNP) is an exogenous peptide synthesized by artificial recombination technology, with a similar structure and similar physiological effects with the endogenous natriuretic peptide secreted by the human body. It’s main mechanism of action is to increase cyclic guanosine monophosphate by binding with its corresponding receptor in the body, regulating, thus, the imbalance of the vascular system and cardiac hemodynamics, improving the heart’s pumping capacity, and inhibiting sympathetic excitability and myocardial remodeling. Moreover, it can promote mitochondrial metabolism and enhance the use of adenosine triphosphate in cardiomyocytes. In the present study, 102 chronic heart failure (HF) patients were randomly assigned to a control and an observation group consisting of 51 patients each. Patients of the control group were treated with standard HF therapy for 3 d including oral metoprolol tartrate tablets, spironolactone, and olmesartanate while patients of the observation group were administered the recombinant human BNP injection for the same time-period, plus the standard HF therapy. The recombinant human BNP group (observation group) demonstrated better physical, emotional, social, and economic scores, as well as cardiac and inflammatory biomarkers such as serum hypersensitive C-reactive protein, N-terminal pro BNP and troponin I levels, compared to the control group. Moreover, cardiac function was also improved, as left ventricular ejection fraction and stroke volume were significantly higher in the observation group than in the control group. Interestingly, adverse reactions were not different between the 2 groups. However, these results are not generalizable and the need of large multicenter randomized controlled trials examining the safety and efficacy of recombinant human BNP in HF patients is of major importance.

Core Tip: Lyophilized recombinant brain natriuretic peptide is an exogenous peptide synthesized by artificial recombination technology, with a similar structure and similar physiological effects with the endogenous natriuretic peptide secreted by the human body. A recent single center, randomized study examined its safety and efficacy in 102 chronic heart failure patients, showing promising results. Larger randomized controlled trials are urgently needed.
