Abstract
Introduction: Finerenone, a third-generation non-steroidal mineralocorticoid receptor antagonist (MRA), offers a targeted approach to managing cardiovascular outcomes, particularly in patients with chronic kidney disease (CKD) and type 2 diabetes (T2D). Unlike traditional MRAs such as spironolactone and eplerenone, which can cause off-target hormonal side effects and hyperkalemia, Finerenone selectively binds to mineralocorticoid receptors, reducing these risks. Recent randomized controlled trials have demonstrated Finerenone's potential to improve cardiovascular outcomes, making it a promising alternative in the management of heart failure and other cardiovascular conditions associated with CKD and T2D. Methods: We conducted a scoping review using PRISMA guidelines. A search for "Finerenone" in the PubMed, Embase, and Cochrane Library databases included randomized controlled trials (RCTs), post hoc analyses, and relevant meta-analyses on cardiovascular outcomes. Data were synthesized narratively, assessing study quality through strengths and limitations. Discussion: Finerenone has shown significant benefits and a superior safety profile compared with traditional MRAs like spironolactone and eplerenone in managing CKD, T2D, and heart failure. It effectively reduces cardiovascular and renal events while minimizing risks such as hyperkalemia and hormonal side effects associated with steroidal MRAs. Future studies, including the REDEFINE-HF, FINALITY-HF, and CONFIRMATION-HF trials, will further explore Finerenone's potential across diverse heart failure phenotypes, including its role in heart failure with mildly reduced and preserved ejection fractions, potentially establishing it as a cornerstone therapy in heart failure management. Conclusions: Finerenone represents a significant advancement in MRA therapy, offering enhanced safety and efficacy in managing cardiovascular outcomes in CKD and T2D patients. The current evidence supports its use as a promising alternative to traditional MRAs, particularly in patients intolerant to steroidal MRAs. Further trials are needed to fully establish its potential across diverse patient populations, including those with varying heart failure phenotypes.
