摘　　要：The present review analyses the mechanisms relating heart failure and hyponatremia,describes the association of hyponatremia with the progress of disease and morbidity/mortality in heart failure patients and presents treatment options focusing on the role of arginine vasopressin(AVP)-receptor antagonists.Hyponatremia is the most common electrolyte disorder in the clinical setting and in hospitalized patients.Patients with hyponatremia may have neurologic symptoms since low sodium concentration produces brain edema,but the rapid correction of hyponatremia is also associated with major neurologic complications.Patients with heart failure often develop hyponatremia owing to the activation of many neurohormonal systems leading to decrease of sodium levels.A large number of clinical studies have associated hyponatremia with increased morbidity and mortality in patients hospitalized for heart failure or outpatients with chronic heart failure.Treatment options for hyponatremia in heart failure,such as water restriction or the use of hypertonic saline with loop diuretics,have limited efficacy.AVP-receptor antagonists increase sodium levels effectively and their use seems promising in patients with hyponatremia.However,the effects of AVP-receptor antagonists on hard outcomes in patients with heart failure and hyponatremia have not been thoroughly examined. 关键词：Heart failure HYPONATREMIA Sodium VASOPRESSIN Vasopressin-receptor ANTAGONISTS TOLVAPTAN CONIVAPTAN Lixivaptan
