- Low-dose mineralocorticoid receptor antagonists (MRAs) increase aldosterone concentrations but may not fully block mineralocorticoid receptor activity.
- Pre-MRA aldosterone levels influence MRA effects: MR activity improves with MRA in high aldosterone patients but worsens in low aldosterone patients.
- Clinical outcomes vary by pre-MRA aldosterone: MRA use improves outcomes in high aldosterone patients but worsens them in low aldosterone patients.
- MRAs are guideline-recommended for heart failure, but these findings suggest personalized approaches based on aldosterone levels could optimize treatment.
