Targeted Potassium Levels for Prevention of ICD Therapy
Arrhythmia Prevention in High Risk Cardiovascular Patients Using Targeted Potassium Levels
Source: ClinicalTrials.gov · Last updated 9 May 2025
Brief summary (registry, in English)
This study evaluates whether a rigorously controlled high-normal level of serum-potassium (4.5-5.0 mEq/L) using dietary recommendations, potassium supplements and mineralocorticoid receptor antagonists will results in a lower incidence of cardiac arrhythmias in patients with an ICD. Patients will be randomized to this treatment or a control arm, where patients will receive usual guideline recommended follow-up.
