Abstract

Purpose of reviewHyperkalemia is a life-Threatening complication of chronic kidney disease (CKD). Risk factors include advanced kidney impairment, diabetes, hypertension, heart failure, and consumption of a K+-enriched diet. High-K+ diets provide health benefits to include reductions in blood pressure, stroke risk, and osteoporosis. Individuals at the highest risk for developing hyperkalemia are those who would benefit most from high K+ diets. Inhibitors of the renin-angiotensin-aldosterone system (RAASi) are effective in reducing cardiovascular events and slowing the progression of CKD, yet hyperkalemia is a risk factor. Discussed are new strategies facilitating use of both high-K+ diets and pharmacology to preserve kidney function and reduce cardiovascular events.Recent findingsSodium zirconium cyclosilicate and patiromer are new K+-binding drugs approved for the treatment of hyperkalemia. Both are efficacious in the short-Term and long-Term treatment of hyperkalemia. These binders are effective in treating hyperkalemia while facilitating RAASi therapy.SummaryHyperkalemia is a life-Threatening condition. New K+-binding drugs allow for optimal use of pharmacological therapy, such as RAASi, enhancing their cardiorenal protection. Health benefits from consumption of high K+ foods may also be enhanced by use of these binders. In conclusion, there are new well tolerated and effective K+-binding agents for acutely and chronically managing hyperkalemia.
