Abstract
Background
The aim of this study was to systematically assess the efficacy and safety of mineralocorticoid receptor antagonists (MRAs) for patients with heart failure (HF) and diabetes mellitus (DM).
Methods
We conducted a comprehensive search for controlled studies that evaluated the efficacy and safety of MRAs in patients with DM and HF. Medline, Embase and Cochrane databases were searched. Two reviewers independently identified citations, extracted data and evaluated quality. Risk estimations were abstracted and pooled where appropriate.
Results
Four observational studies were included. MRAs use was associated with reduced mortality compared with controls (RR = 0.78; 95 % CI: 0.69–0.88; I 2 = 0 %; P < 0.001). Increased risk of developing hyperkalaemia was observed in those patients taking MRAs (RR = 1.74; 95 % CI: 1.27–2.38; I 2 = 0 %; P = 0.0005).
Conclusions
The current cumulative evidence suggests that MRAs can improve clinical outcomes but increase the risk of hyperkalaemia in patients with DM and HF.
