Abstract: This study evaluates the efficacy of a simplified risk score derived from the Acute Decompensated Heart Failure National Registry (ADHERE) in predicting in-hospital mortality among patients with acute heart failure and reduced ejection fraction. The model utilizes readily available clinical parameters to enable rapid bedside risk stratification and support clinical decision-making in acute care settings. Given the heterogeneity in patient presentation and outcomes, reliable risk prediction tools are essential for optimizing management and resource allocation. The discriminatory power and calibration of the ADHERE risk model were assessed in a specific patient cohort and compared with alternative prognostic scores. Particular attention was given to the contribution of individual components, including admission B-type natriuretic peptide (BNP), and the clinical relevance of common practices such as in-hospital observation on oral diuretics. Findings highlight the utility of simplified risk models while underscoring the need for external validation across diverse populations. Emerging strategies, including multimarker approaches integrating natriuretic peptides, cardiac troponins, and inflammatory markers, may enhance predictive accuracy. Furthermore, incorporation of echocardiographic parameters and advanced analytical methods, such as machine learning, offers potential for improving individualized risk assessment. Despite promising advancements, challenges remain in standardizing biomarker use and translating complex models into routine clinical practice. Overall, this study supports the continued refinement of risk stratification tools to improve prognostication and guide personalized management in heart failure.
