Does the presence of KCNJ5 gene mutations affect postoperative LVMI improvements and cardiovascular complications in Japanese patients with aldosterone-producing adenomas?
KCNJ5 mutations are highly prevalent in Japanese APA patients and are associated with significant postoperative improvements in LVMI, highlighting the need for precise diagnosis to manage cardiovascular risk.
The present findings clearly demonstrated that KCNJ5 mutations are common among Japanese APA patients (frequency: 69.4%). In this study, the KCNJ5-mutated group demonstrated significant postoperative improvements in LVMI, possibly due to strong autonomous aldosterone production. Hence, it is necessary to precisely diagnose younger APA patients possessing a strong capacity for aldosterone production due to KCNJ5 gene mutations, as such cases may be easily complicated by cardiovascular events.
