Cardiovascular Outcomes of KCNJ5 Mutated Aldosterone-Producing Adenoma: A Systematic Review

Endocr PractPublished Systematic review of observational studies

Authors' conclusion

This systematic review provided evidence of the significant association between KCNJ5 mutation and unfavorable cardiovascular outcomes in patients with primary aldosteronism. Further research is needed to improve the quality of evidence on this topic and elucidate the underlying mechanisms of the potential burden of KCNJ5 mutation.

Pooled result

As reported in the abstract

  • Cardiac function (3 studies): all reported an association between impaired cardiac functions and KCNJ5 mutation status
  • Cure of hypertension after surgery (6 studies): all showed KCNJ5 mutation significantly associated with cure of hypertension
