    Abstract:
    PURPOSE OF REVIEW: Hyperkalaemia is a frequent and sometimes life-threatening condition that may be associated with arrhythmia and cardiac dysfunction. Evaluating the prevalence of hyperkalaemia in patients with heart failure (HF) and potential treatments of this condition is essential for patients using renin-angiotensin-aldosterone system inhibitors or angiotensin receptor-neprilysin inhibitor and mineralocorticoid receptor antagonists, which represent the cornerstone and highly proven life-saving therapy. RECENT FINDINGS: Novel findings from the past few years include data regarding the epidemiology, pathomechanisms, implications and novel therapeutic approaches to counteract hyperkalaemia in patients with HF. Whilst older potassium-binding agents are associated with serious adverse events, novel potassium-binding drugs are effective in lowering potassium levels and are generally well tolerated. Hyperkalaemia represents both a direct risk of cardiovascular complication and an indirect biomarker of the severity of the underlying disease such as neurohormonal activation and renal dysfunction. Novel potassium-binding drugs such as patiromer and sodium zirconium cyclosilicate may help to optimize therapy in HF and achieve guideline-recommended doses.
