Patients with heart failure (HF) are prone to combine with renal insufficiency. Recently, LCZ696 has been used in the treatment of HF, but whether LCZ696 is better than angiotensin converting enzyme inhibitors/angiotensin receptor antagonists (ACEI/ARB) in renal protection for HF patients has not been investigated. Therefore, we conducted a meta-analysis focusing on LCZ696 and its role in preservation of renal function in HF patients. Embase, PubMed, the Cochrane Library and ClinicalTrials.gov databases were electronically searched for available randomized controlled trials (RCTs). HF patients taking LCZ696 or ACEI/ARB were assessed for renal adverse events. The last search date was Sep 20, 2019. A total of 14959 patients from 6 trials were included in this meta-analysis. As compared to ACEI/ARB, LCZ696 significantly reduced the risk of renal function deterioration (odds ratio 0.77, 95% confidence interval 0.61-0.97, P = 0.02). In summary, LCZ696 may have superior renal protection in HF patients compared with ACEI/ARB.
