To the Editor We read with interest the recent article by Aliti et al,1 which reported that the 30-day readmission rates were significantly higher in subjects with elevation in brain-type natriuretic peptide (BNP) level greater than 700 pg/mL (to convert to nanograms per liter, multiply by 1) at the time of discharge who received aggressive fluid and sodium restriction during hospitalization for acute decompensated heart failure. The authors were able to add more data to the continuing narrative on the controversy surrounding salt restriction on health.2 Furthermore, we were interested in the study in that it examined the impact of a nonpharmacological intervention during an acute hospitalization on 30-day readmission rates, as most literature and studies focus on the processes surrounding failures in communication, in planning, and in scheduling follow-up or on performance measure outcomes.3,4
