Abstract/OtherAbstract:
PURPOSE: NT-proBNP is an important prognostic predictor in patients with heart failure. However, it is unknown whether a change of NT-proBNP plasma levels in the early phase of decompensation might be of additional prognostic value in patients with acute decompensation of heart failure.
METHODS AND RESULTS: NT-proBNP plasma levels of 116 patients with decompensated heart failure from ischemic/non-ischemic origin were measured at baseline and at 12, 24 and 48 h after hospital admission. Baseline levels and changes of plasma levels within the first 48 h were correlated with 30-day mortality. In all patients, NT-proBNP 12 h after admission was highest and superior with respect to the prediction of 30-day mortality compared to plasma levels on admission. In total, 38 patients died within the first 30 days. In these patients absolute NT-proBNP plasma levels were significantly higher and the increase within 12 h after admission was more pronounced compared to survivors (p<0.001). NT-proBNP at 12 h after admission also had the highest predictive value for the 30-day mortality rate in patients with acute myocardial infarction. The increase of NT-proBNP plasma levels within 12 h after admission had the highest predictive value in patients suffering from decompensated heart failure.
CONCLUSIONS: NT-proBNP is a powerful marker of 30-day mortality in patients with decompensated heart failure of ischemic and non-ischemic origin. Compared with single baseline measurements, serial measurements of NT-proBNP plasma levels within 12 h after hospital admission may be used to increase the predictive value of NT-proBNP with regard to the early identification of patients who are at high risk of mortality.
