Heart failure & cardiomyopathiesMeta-analysis

Safety and efficacy of early initiation of mineralocorticoid receptor antagonist after an acute decompensated heart failure event or acute myocardial infarction with cardiac dysfunction: a meta-analysis of randomized clinical trials

ESC Heart FailPublished

  • meta-analysis of randomized controlled trials
  • pre-specified subgroup analysis by clinical setting (acute ischaemic vs non-ischaemic heart failure (HF))

Authors' conclusion

Early MRA initiation was associated with improved prognosis when compared with usual care, though accompanied by an increased risk of hyperkalaemia, warranting close follow-up after initiation.
