Prediction of mortality of patients with suspected heart failure by brain natriuretic peptide concentrations 100 pg/ml: comparison of a clinical model with brain natriuretic peptide concentrations

摘要

The test for heart failure with the highest sensitivity (94%) and specificity (70%) is clinical suspicion combined with a brain natriuretic pep tide (BNP) concentration > 100 pg/ml. BNP concentration is also an independent predictor of mortality in heart failure. However, its value in predicting mortality compared with other traditional clinical findings and laboratory parameters has not been reported. This study compared the prediction of heart failure mortality within 30 days by BNP concentrations with a predictive model based on classic clinical findings recently described by Lee et al.
