Losing at least 2 kg during a heart failure hospitalization is linked to a significantly lower risk of being readmitted within 30 days. A Swedish registry study of nearly 5,000 patients found that those treated with IV diuretics who hit that weight-loss threshold had a 41% lower rehospitalization risk. The protective effect, however, didn't last beyond the 30-day mark.
For heart failure patients, the scale in the hospital room might be more important than previously thought. A new study published in Heart found that patients hospitalized for heart failure who lost at least 2 kg during their stay — a sign of successful fluid removal — were significantly less likely to be readmitted within 30 days compared to those who didn't hit that threshold.
The Swedish registry study tracked nearly 5,000 patients treated with intravenous loop diuretics between 2017 and 2021. The median weight loss during hospitalization was 2.5 kg, and 59% of patients achieved the 2 kg target. Importantly, the benefit held up across different biomarker subgroups, including patients with worsening kidney function — a common concern with aggressive diuresis.
Key Takeaways:
Why it matters: Readmission after heart failure hospitalization is a major clinical and financial burden. This study reinforces that achieving adequate decongestion — measurable simply by weight — is a meaningful short-term goal that clinicians can target during inpatient care.
