This study explores the clinical implications of potassium management in heart failure (HF) and atrial fibrillation (AF) through a PICO framework. It reviews a meta-analysis of 12 trials involving 46,069 patients, focusing on potassium categories and their impact on outcomes. Key findings reveal a risk nadir of 4.2–5.0 mmol/L, highlighting differences in heart failure types and kidney function. The results emphasize the importance of potassium monitoring in clinical practice, informed by the...
