Hypochloraemia is Strongly and Independently Associated with Mortality in Patients with Chronic Heart Failure

Abstract

Serum chloride is strongly and independently associated with worsened survival in patients with chronic heart failure and accounted for the majority of the risk otherwise attributable to hyponatraemia. Given the critical role of chloride in a number of regulatory pathways central to heart failure pathophysiology, additional research is warranted in this area.
