Long-Term Potassium Monitoring and Dynamics in Heart Failure and Risk of Mortality
Information type: Other primary research
Source: Circulation Research
Specialities: Cardiovascular system disorders | Renal and urologic disorders
Summary
Study (n=2164) found follow-up trajectory of serum potassium levels independently predicted mortality through a U-shaped association, with higher risk at both ends of distribution, highlighting need for close monitoring of levels after episode of acute decompensated heart failure
UKMi comment
An editorial notes that this study provides further compelling evidence of the strong association between serum potassium and mortality, and it takes existing data a step further by establishing that keeping serum potassium levels within a normal range over time is a critical therapeutic target to optimize outcomes in heart failure.
