Systematic Review: Effects of ACE inhibitors and ARBs on kidney and cardiovascular outcomes in diabetic patients – Cochrane Library

This systematic review and meta-analysis evaluated the effectiveness of angiotensin-converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARBs) in managing cardiovascular and kidney outcomes in adults with diabetes and kidney disease. It included data from 109 randomized controlled trials totaling 28,341 participants, comparing the impact of ACEi and ARBs, either alone or in combination, against each other, placebo, or no treatment.
Main Findings:
The analysis revealed that ACEi may reduce the risk of kidney failure (RR 0.61, 95% CI 0.39 to 0.94) but generally has little effect on all-cause mortality and cardiovascular death compared to placebo, with low certainty of evidence. Similarly, ARBs showed potential in preventing kidney failure (RR 0.82, 95% CI 0.72 to 0.94) and the progression from microalbuminuria to macroalbuminuria. The effects on cardiovascular outcomes remained uncertain and showed minimal difference compared to placebo or no treatment.
Implications for Practice:
While ACEi and ARBs may aid in preventing kidney failure in patients with diabetic kidney disease, their broader impacts on mortality and cardiovascular health remain uncertain. This underscores the necessity for further rigorous research to verify these findings and better determine the optimal therapeutic strategies. Clinicians should weigh these results against individual patient profiles considering the overall low certainty of the evidence.
