A Clinical Trial to Define the Best Strategy for the Management of Heart Failure in Elderly Patients

Официальное название

A Randomized Clinical Trial to Define the Best Strategy for the Management of Heart Failure and Chronic Kidney Disease Among Elderly Patients With or at High Risk of hyperKalemia in Span by Optimizing the Use of RAASi With SZC

Обзор

Heart failure (HF) and Chronic Kidney Disease (CKD) patients are frequently not administered renin-angiotensin aldosterone system inhibitor (RAASi) therapies at recommended doses due to hyperkalaemia, despite proven mortality and morbidity benefits. Sodium zirconium cyclosilicate (SZC) is a nonabsorbed potassium binder proven to lower serum potassium (S-K) and maintain normokalaemia. The purpose is to assess if a treatment regimen containing SZC will allow RAASi therapies to be optimized to target doses in patients with heart failure, chronic kidney disease and elevated serum potassium or at risk of developing elevated serum potassium.

Подробное описание

This is a randomized clinical trial, multicentre, parallel group, open label, to evaluate the use of sodium zirconium cyclosilicate (SZC) to optimize RAASi therapy in patients with heart failure and chronic kidney disease, through up-titration of ACEi, ARB, ARNI or MRA therapy according to clinical guidelines (1), without inducing clinically significant hyperkalemia. Eligible subjects will have been admitted to hospital because of an HF (NYHA I- III) decompensation, will have required intravenous diuretics and will have had mild hyperkalaemic values that needed stabilization or be at risk of developing hyperkalaemia. Subjects will be randomised in a 1:1 ratio to receive SZC or none (standard of care treatment without potassium binders) for 3 months while optimizing RAASi therapies according to the European Society of Cardiology (ESC) guidelines.
