Mineralocorticoid receptor antagonists and atrial fibrillation: a meta-analysis of clinical trials

Eur Heart JPublished

  • Systematic review and meta-analysis of randomised trials
  • random-effects models
  • interaction analyses

Authors' conclusion

Mineralocorticoid receptor antagonists are similarly effective in preventing cardiovascular events in patients with and without HF and most likely retain their efficacy regardless of AF status. Mineralocorticoid receptor antagonists may also be moderately effective in preventing incident or recurrent AF events.
