Spot Urine Sodium-to-Potassium Ratio Predicts Stroke Risk
Dietary sodium reduction with the concurrent increase in potassium intake is a current public health priority to reduce the risk of cardiovascular events. This study explored associations between the spot urine sodium-to-potassium ratio and cardiovascular events in the MESA (Multi-Ethnic Study of Atherosclerosis) longitudinal cohort.
The spot urine sodium-to-potassium ratio (measurable in routine care) is associated with stroke. A urine sodium-to-potassium ratio of ≤1, may be related to a clinically relevant reduction in stroke risk and is a feasible target for health interventions.
