Methods A total of 322 patients with chronic heart failure from Feb .2006 to Aug .2012 were retrospectively reviewed and random-ly divided into hyponatremia group(n=161) and normal serum sodium group(n=161) .The clinical data of the two groups were compared .Results There were significant difference between the two groups in the BNP levels ,length of stay ,hospital mortality and readmission rates(P<0 .05) .Serum sodium concentration in hyponatremia group was decreased with the decrease of cardiac function(P<0 .05) ,BNP levels was elevated with the decrease of blood sodium level (P<0 .05) ,days of hospitalization and hospital mortality were increased with the decrease of cardiac function (P< 0 .05) .Conclusion Patients with heart failure combined hy-ponatremia have poor cardiac function ,higher in-hospital mortality and readmission rates and longer hospital stay .
