Serum Potassium and Clinical Outcomes in Heart Failure Patients: Results of Risk Calculations in 21 334 Patients in the UK

Abstract

In UK patients with new onset heart failure, both hypokalaemia and hyperkalaemia were associated with increased mortality risk, and hyperkalaemia was associated with increased likelihood of RAASi discontinuation. Our results demonstrate the potential importance of serum potassium monitoring for heart failure outcomes and management.
