Methods This was a multicenter Italian 8 centers observational study Italian Research Emergency Department RED . 287 patients with ADHF were studied through physical exams lab tests chest X Ray electrocardiograms ECGs and BNP measurements performed at admission at 24 hours and at discharge. Follow up was performed 180 days after hospital discharge. Logistic regression analysis was used to estimate odds ratios OR for the various subgroups created. For all comparisons a P value was considered statistically significant. Results BNP median interquartile range IQR value at admission was 822 412 - 1390 pg mL at 24 hours was 593 270 - 1953 and at discharge was 325 160 - 725 . A BNP reduction of 46 at discharge had an area under curve AUC of P for predicting future adverse events. There were 78 events through follow up and in 58 of these patients the BNP level at discharge was 300 pg mL. A BNP reduction of after 24 hours had an AUC at ROC curve of for predicting adverse events P . The odds ratio of the patients whose BNP level at discharge was 300 pg mL and whose percentage decrease at discharge was 46 compared to the group whose BNP level at .
