Why the study?
Few prognostic risk scores have been routinely used in acute decompensated heart failure, motivating the external validation of three published scores and the derivation of a new score.
Does a newly derived prognostic risk score improve the prediction of short-term outcomes in patients with acute decompensated heart failure compared to existing scores?
Population
4550 patients with ADHF from the Heb-ADHF registry in China
Comparison
New prognostic risk score vs 3A3B, AHEAD, and OPTIME-CHF scores
Design
Registry-based derivation and validation cohort study

New PRS may improve short-term ADHF risk stratification over existing scores; leaves open clinical utility pending prospective validation.
Does a newly derived prognostic risk score improve the prediction of short-term outcomes in patients with acute decompensated heart failure compared to existing scores?
A newly derived prognostic risk score incorporating QRS fraction and other clinical variables showed better short-term predictive ability for acute decompensated heart failure than existing scores.
Zhao et al. (2022) studied this question.
