Serum electrolytes and the risk of in-hospital mortality in patients with decompensate heart failure

Shenzhen Peoples Hospital
Introduction: We aimed to retrospectively analyse the correlation between serum electrolytes levels and prognosis of severe decompensate chronic heart failure, and to investigate if there were other factors that could affect the prognosis.
Methods: Retrospective analysis data of 261 cases of decompensate heart failure with NYHA class III~IV that were included between January 2003 and December 2004 at Shenzhen People’sHospital , China
Results: (1) Patients in the death group had a higher proportion of hyperkalemia (p < 0.0001), hyponatremia (p = 0.048), hypocalcaemia (p < 0.0001) and cardiac structural abnormalities (p < 0.0001). (2) Serum calcium levels and cardiac structural abnormalities entered the regression model.
Conclusion: The values of admission serum potassium, sodium, calcium could be used to predict mortality of decompensate chronic heart failure patients, and serum calcium levels should be an independent predictor of the prognosis of severe decompensate heart failure.
