Risk of hypertension and heart failure linked to high-normal serum sodium and tonicity in general healthcare electronic medical records
To evaluate whether hydration-related markers, serum sodium and tonicity, can serve as risk factors for hypertension and heart failure.
Key Findings:
Higher serum sodium levels are associated with increased risk of hypertension: 13% rise at 140–142 mmol/L and 29% for levels above 143 mmol/L.
Tonicity over 287 mosmol/kg is linked to a 19% increased risk of hypertension.
The risk of heart failure increases by 20% for sodium above 143 mmol/L and 15% for tonicity above 289 mosmol/kg.
Interpretation:
Serum sodium and tonicity levels exceeding 140 mmol/L and 287 mosmol/kg are associated with increased risks of hypertension and heart failure, suggesting the need for hydration-focused interventions.
Limitations:
The study is retrospective and relies on electronic medical records, which may have inherent biases.
The analysis was limited to individuals without significant chronic diseases and water balance issues.
Conclusion:
Monitoring serum sodium levels, particularly those in the upper normal range, could help identify individuals at risk for hypertension and heart failure, guiding preventive strategies.
