59TH ERA CONGRESS: Independent symposium webcast

Chaired by Claire Sharpe with Pantelis Sarafidis, David Thomas & Ellen Hoogeveen


Watch Prof Claire Sharpe and colleagues in this independent symposium hosted at ERA 2022, where they discussed how to reduce the burden of hyperkalemia whilst maintaining cardio-renal protection for people with chronic kidney disease, with a particular focus on the use of novel K+ binders.

Learning objectives

After watching the webcast you will be able to:

1. Interpret K+ concentration alongside other patient risk- and clinical-based measures to inform hyperkalemia management and monitoring
2. Utilize the emerging evidence and guidelines for the optimization of RAASi therapy when risk of hyperkalemia is high
3. Explain the role of newer K+ binders in the management of hyperkalemia whilst maintaining cardio-renal protection
