Why the study?
Does a change in serum sodium concentration after discharge predict long-term mortality in patients hospitalized with heart failure and hyponatremia?

In patients hospitalized with heart failure and hyponatremia, an increase in serum sodium concentration after discharge is strongly associated with improved long-term survival.
No takes yet. Share an insight, caveat, or question.
Serum sodium rise after HF discharge is prognostic; leaves open whether correction improves survival.
Madan et al. (2011) studied this question.
