A simple prognostic model for assessing in-hospital mortality risk in patients with acutely decompensated heart failure

Background: An assessing of the in-hospital mortality risk for an emergency hospitalized patient with acutely decompensated heart failure (ADHF) is challenging task. Simple formula can help. Methods: On the base of six indicators identified in derivation group, simple formula for assessing the risk for in-hospital mortality of ADHF patients was derived and later tested in validation group. Results: The retrospective analysis of a derivation group (533 survivors, 121 deceased) identified six risk indicators: age, heart rate (HR), systolic blood pressure (SBP) and serum concentrations of urea, sodium (Na) and uric acid (UA). The final formula was created ([age/10]2 × HR/SBP)+(Urea-Na/10)+UA/100 and formula result of 53 was established as cut-off result. In the derivation group, at the cut-off point of 53, area under the ROC curve (AUC) was 0.741 (95% CI 0.701–0.776) ; with sensitivity 54% and specificity 83%. The discriminative capacity of the formula was significantly higher than each of its components. In the validation group of 591 patients (527 survived, 64 died) AUC was also 0.741 (95% CI 0.706–0.774), sensitivity was 66% and specificity 76%. Positive predictive value (PPV) of the developed formula was modest (34%), but negative predictive value (NPV) was 95%. N-terminal pro-B type natriuretic peptide and troponin I were determined, but not included into formula. Conclusions: The developed formula enables simple, rapid and inexpensive risk assessment, but its disadvantage is a low PPV. However, a high NPV permits the identification of patients with a low risk of in-hospital mortality, which could lead to a more rational patient treatment.
