PROGNOSTIC VALUE OF SERUM SODIUM AND CHLORINE LEVEL IN ACUTE DECOMPANSE HEART FAILURE

ABSTRACT 
Aim: Acute heat failure is a significant reason of morbidity and mortality that is commonly seen in the emergency department. In our study, we aimed to investigate the effectiveness of serum sodium and chloride levels for predicting the prognosis of the patients with acute decompensated heart failure. 
Material and Method: Our study has been conducted in Health Sciences University Emergency Medicine Department Ankara Health Application and Research Center Emergency Clinic (SBÜ Acil Tıp ABD Ankara SUAM Acil Tıp Kliniği) between 1.12.2018 and 1.12.2019 after receiving ethics committee’s approval. Our study is a prospective, observational clinical trial. 120 patients older than 18 years old with informed consent who admitted to emergency department with the diagnoses of acute heart failure and acute decompensation of chronic heart failure were included without any exclusion criteria. The cases included in our study were divided into 3 groups; the patients who had got treated in the emergency department and discharged from the hospital, the patients who were hospitalized in cardiology clinic and the patients who were hospitalized in intensive care unit. Serum sodium and chloride levels in blood samples were compared when these 3 groups of patients were admitted to the emergency department. 
Results: 48.3% (n:58) of patients were discharged from the hospital while 26.7% (n:32) of patients were hospitalized and 25% (n:30) of patients were hospitalized in intensive care unit. The patients with serum chloride levels below than 98.5 mmol/l needed longer hospitalization while no significant correlation between serum sodium levels and hospitalization ratio was detected. 
Conclusion: Lower serum chloride level is a valuable indicator for evaluating the prognosis and predicting the need of hospitalization of the patients who were admitted to the emergency department with acute heart failure. There was no correlation between the serum sodium levels and prognosis and the need for hospitalization.
