Prognostic scores in heart failure - Critical appraisal and practical use.

Survival in patients with heart failure in the last two decades has significantly improved, owing to availability of new drugs, devices, and technologies. However, these new therapeutic tools are often costly and not without attendant risks. Thus, accurate and reproducible risk stratification is required to assess appropriateness of therapy. Although a growing body of evidence has characterized various predictors of poor outcomes, the application of comprehensive prognostic models in clinical practice remains limited. Herein, we critically evaluate the utility of prognostic scores in heart failure, discussing the strategies to select the most efficient and appropriate risk estimator in the individual patient.
