Hyperkalaemia is an electrolyte imbalance that impairs muscle function and myocardial excitability, and can potentially lead to fatal arrhythmias and sudden cardiac death. The prevalence of hyperkalaemia is estimated to be 6%-7% worldwide and 7%-10% in Asia. Hyperkalaemia frequently affects patients with chronic kidney disease, heart failure, and diabetes mellitus, particularly those receiving treatment with renin-angiotensin-aldosterone system (RAAS) inhibitors. Both hyperkalaemia and interruption of RAAS inhibitor therapy are associated with increased risks for cardiovascular events, hospitalisations, and death, highlighting a clinical dilemma in high-risk patients. Conventional potassium-binding resins are widely used for the treatment of hyperkalaemia; however, caveats such as the unpalatable taste and the risk of gastrointestinal side effects limit their chronic use. Recent evidence suggests that, with a rapid onset of action and improved gastrointestinal tolerability, novel oral potassium binders (e.g., patiromer and sodium zirconium cyclosilicate) are alternative treatment options for both acute and chronic hyperkalaemia. To optimise the care for patients with hyperkalaemia in the Asia-Pacific region, a multidisciplinary expert panel was convened to review published literature, share clinical experiences, and ultimately formulate 25 consensus statements, covering three clinical areas: (i) risk factors of hyperkalaemia and risk stratification in susceptible patients; (ii) prevention of hyperkalaemia for at-risk individuals; and (iii) correction of hyperkalaemia for at-risk individuals with cardiorenal disease. These statements were expected to serve as useful guidance in the management of hyperkalaemia for health care providers in the region.
高钾血症是一种电解质失衡,可损害肌肉功能和心肌兴奋性,并可能导致致命性心律失常和心源性猝死。高钾血症的患病率估计在全球为 6%-7%,在亚洲为 7%-10%。高钾血症常影响慢性肾脏病、心力衰竭和糖尿病患者,尤其是接受肾素-血管紧张素-醛固酮系统(RAAS)抑制剂治疗的患者。高钾血症和 RAAS 抑制剂治疗中断都与心血管事件、住院和死亡风险增加相关,这凸显了高危患者面临的临床困境。传统的钾结合树脂广泛用于治疗高钾血症;然而,其味道不佳和胃肠道副作用风险等缺点限制了其长期使用。最近的证据表明,新型口服钾结合剂(如帕替络尔和硅酸锆钠)具有起效迅速和改善胃肠道耐受性的特点,是急性和慢性高钾血症的替代治疗选择。为了优化亚太地区高钾血症患者的治疗,一个多学科专家小组对已发表的文献进行了回顾,分享了临床经验,并最终制定了 25 项共识声明,涵盖三个临床领域:(i)高钾血症的危险因素和易感患者的危险分层;(ii)高危个体的高钾血症预防;和(iii)有心血管和肾脏疾病的高危个体的高钾血症纠正。这些声明有望为该地区的医疗保健提供者在高钾血症的管理中提供有用的指导。
