Recent research provides conflicting evidence on the relationship between potassium levels and atrial fibrillation risk after cardiac surgery.

Recent studies have shown conflicting results regarding potassium levels and atrial fibrillation (AF) risk after cardiac surgery. One study indicated that higher potassium levels post-surgery reduced AF risk by 25%. However, the TIGHT K trial found no significant difference in AF occurrence between patients with strict versus relaxed potassium thresholds. This suggests that maintaining tight potassium control may be unnecessary, potentially lowering healthcare costs without increasing risks.
