heart failure is one of the main reasons for consultation to the emergency room and of in-hospital mor­ tality. Objective: to describe the risk of the latter by means of applying two instruments to patients who were hospita­ lized with acute decompensated heart failure at the internal medicine service at Hospital de San Jose de Bogota DC. Methods: 155 patients were recruited between March 2010 and February 2011, applying the GWTG-HF risk score and the OPTIMIZE Study Risk-Prediction Nomogram, describing clinical and demographic variables. The expected and observed mortality is reported. Results: patients had an average age of 72.5 (SD 12.1) years. In-hospital mortality was documented in 7.7 % (n 12). Risk stratification was performed in 146 cases. 64.3% were classified within risk 1 to 5% by means of the AHA tool and 50.7% using the OPTIMIZE HF Nomogram. More than half of the demised patients had a low risk (1% to 15%). No concordance between methods was found (Lin 0.07). Pro BNP levels greater than 12.500 pg/ml and arrhythmia at the moment of admission were frequently reported among the group of deceased patients. These variables are not considered by the instruments that were used. Conclusions: the use of risk rates for in-hospital mortality may be a useful tool. Nevertheless, other studies are required in order to apply them on our population.
