Chronic Hyperkalemia in Cardiorenal Patients: Risk Factors, Diagnosis, and New Treatment Options

Area of Science:

• Nephrology
• Cardiology
• Internal Medicine

Background:

• Chronic hyperkalemia (HK) is a serious condition often seen in patients with chronic kidney disease (CKD) and heart failure (HF).
• CKD, HF, diabetes, and renin-angiotensin-aldosterone system inhibitor use are known risk factors for developing HK.
• Current therapeutic options for HK are suboptimal, impacting many CKD and HF patients.

Purpose of the Study:

• To review the primary risk factors associated with the development of chronic hyperkalemia.
• To provide a diagnostic guide for effectively identifying HK in at-risk patient populations.
• To present and discuss novel therapeutic strategies for managing HK.

Main Methods:

• Literature review focusing on risk factors, diagnostic criteria, and emerging treatments for chronic hyperkalemia.
• Analysis of current clinical guidelines and recent research on HK management.
• Synthesis of information to guide cardionephrologists in patient care.

Main Results:

• Identification of key patient groups and clinical factors contributing to HK.
• Outline of diagnostic approaches to ensure timely and accurate HK detection.
• Overview of advancements in HK treatment, addressing limitations of current therapies.

Conclusions:

• Effective management of chronic hyperkalemia is crucial for improving outcomes in CKD and HF patients.
• A comprehensive understanding of risk factors and diagnostic tools is essential.
• New therapeutic avenues offer promise for optimizing HK treatment and patient care.
