为提高心力衰竭治疗效果，探讨低钠血症与心衰预后的关系。方法：对３７例充血性心力衰竭进行回顾性研究，检测治疗前与治疗后多次血清电解质含量进行对比。结果：血清钠 ≥１３５ ｍｍｏｌ／Ｌ者 １９例，死亡 １例；血清钠 ≤ １３４ ｍｍｏｌ／Ｌ者 １８例，死亡 ５例，死亡率显著增加。结论：治疗前后血清钠的变化与心衰预后有显著性差异（Ｐ＜０．０１），说明低钠血症严重影响心衰患者的预后。
To improve the therapeutic effect of heart failure, to explore the relationship between hyponatremia and prognosis of heart failure. Methods: Thirty-seven patients with congestive heart failure were retrospectively studied. The levels of serum electrolytes before and after treatment were compared. Results: Serum sodium ≥135 mmol / L in 19 cases, 1 death; serum sodium ≤ 134 mmol / L in 18 cases, 5 deaths, the mortality increased significantly. Conclusion: The change of serum sodium before and after treatment has significant difference with the prognosis of heart failure (P <0.01), indicating that the prognosis of patients with heart failure is seriously affected by hyponatremia.
