Association Between Serum Sodium Level Trajectories and Survival in Patients with Heart Failure

ESC Heart FailPublished Retrospective cohort study

Authors' conclusion

Serum sodium level trajectories were associated with mortality in patients with HF.

Study context

Participants

Exposure
Serum sodium trajectories over first 48 h vs normal-steady-state trajectory
Outcome
Mortality
Follow-up
