Expert Round Table: Hyperkalaemia Management in the Cardio-Renal Patient

Patients with both chronic kidney disease and heart failure present a unique range of challenges to physicians, particularly in relation to the use of Renin Angiotensin Aldosteron System Inhibition (RAASi).

Cardio-renal patients are treated with RAASi therapy at high doses[1] due to their positive effects in reducing proteinuria, hypertension and improving outcomes[2]; as recommended in heart failure[3],[4],[5] and KDIGO renal guidelines.[6]  However, these benefits need to be considered in the context that RAASi therapy may cause or worsen hyperkalaemia,[7] requiring a dose reduction or discontinuation of RAASi treatment,[8],[9],[10] a change which is associated with poor patient outcomes.[11]

In recognition of this, COMPACT RENAL assembled an expert panel in spring 2017 to discuss the specific problems which cardio-renal patients face, as well as possible solutions to these challenges.

Professor Carolyn Lam Su Ping from the Asia Pacific region provided the cardiologist perspective and Asian clinical experience in the panel, with Professors Angel de Francisco (Spain), Austin Stack (Ireland ) and Laurent Juillard (France) adding insights into nephrology practices across Europe.

Whether we’re cardiologists or nephrologists, sometimes we have to dose-reduce or indeed, as kidney function declines, stop [RAASi] therapies – stopping therapies that have a potential therapeutic value.”

– Professor Austin Stack

In this round table video, the panel discusses:

  • How to define the cardio-renal patient and the need for greater collaboration between specialties
  • The considerable benefits of RAASi therapy at optimal doses for cardio-renal patients, as well as the difficulties in maintaining the therapeutic doses of RAASi, due to hyperkalaemia in the presence of declining kidney function
  • Current treatment options for hyperkalaemia, both acute and chronic[12]
  • The needs that physicians would like to see met by future hyperkalaemia therapies
