Comparing the effect of Angiotensin-Converting Enzyme Inhibitors versus Angiotensin Receptor Blockers in heart failure patients with type 2 diabetes mellitus: a systematic review

Introduction: Heart failure is a prevalent world wide. Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers are widely prescribed. The aim of this study was to determine the effect of the two drugs in heart failure patients with type 2 diabetes mellitus.Methods: This meta-analysis was performed on research articles on the drugs of heart failure patients in PubMed, ProQuest and EBSCO database published between 2008-2018. Pooled odds ratio (OR) are calculated using fixed and random effects models. Data were processed using Review Manager 5.3 (RevMan 5.3).Results: From total 209 articles, 10 studies met the criteria for systematic review. Meta-analysis result showed that there were no difference effect of angiotensin-converting enzyme inhibitors versus angiotensin receptor blockers in heart failure patients with type 2 diabetes mellitus (RR = 1.73 [95% CI 0.88-3.40], p=0.11). Heterogeneity test for studies (Pheterogeneity = p = 0.334) and Begg’s test (p = 0.180).Conclusion: This analysis confirmed there were no difference effect of angiotensin-converting enzyme inhibitors (ACEi) versus angiotensin receptor blockers (ARBs) in heart failure patients with type 2 diabetes mellitus
