Abstract
Patients hospitalized for heart failure (HF) remain at high risk for early readmission. A post hoc analysis was performed of the biomarker substudy of the ASCEND-HF trial. An in-hospital congestion score was derived using orthopnea, pedal edema, and NT-proBNP levels. Its added prognostic value beyond traditional risk factors was assessed by determining the net reclassification index (NRI). Study participants (n = 884) had a median age (years) of 67 (55–77), 68% were male, and the median (25th–75th) ejection fraction (%) was 26 (20–40). After adjustment, increasing congestion score was associated with 30-day all-cause mortality or HF hospitalization (odds ratio = 1.51, 95% confidence interval [CI] 1.28–1.77, p < 0.001) and 180-day all-cause mortality (hazard ratio = 1.48, 95% CI 1.28–1.72, p < 0.001). However, adding the congestion score to the multivariable model did not significantly impact the NRI. A higher in-hospital congestion score portended a poor short-term prognosis but did not significantly reclassify risk.
