Key result
LVEF <40% linked to ~111% higher 30-day ADHF readmission risk alongside hyponatremia and ACS.
Why the study?
High rates of hospital readmission after acute decompensated heart failure cause increased costs and worsening ventricular function, necessitating identification of predictors of rehospitalization.
Cohort (n=312)
No
Odds Ratio: 2.11 (95% CI 1.21–3.69)
p-value: p=0.009
In patients with acute decompensated heart failure, ejection fraction <40%, hyponatremia, and acute coronary syndrome as the cause of decompensation are independent predictors of 30-day hospital readmission.

May support risk stratification for closer follow-up in ADHF; hypothesis-generating and requires prospective validation before guiding interventions.
Sarteschi et al. (2019) conducted a cohort in Acute decompensated heart failure (n=312). Left ventricular ejection fraction < 40% vs. Left ventricular ejection fraction ≥ 40% was evaluated on Hospital readmission within 30 days of discharge (OR 2.11, 95% CI 1.21-3.69, p=0.009). Reduced left ventricular ejection fraction <40% (OR 2.11), hyponatremia (OR 2.87), and acute coronary syndrome (OR 1.89) were independent predictors of 30-day hospital readmission in patients with acute decompensated heart failure.
