Abstract/OtherAbstract:
BACKGROUND: Recently it has been found that BNP and NT-proBNP provide independent prognostic information in patients with acute coronary syndromes (ACS). However, little data are available on the time course of NT-proBNP levels in relation to onset of symptoms. METHODS AND RESULTS: We included 765 patients (236 females, aged 64 +/- 11 years) with an ACS (STEMI 42%, NSTEMI 41%, UAP 17%), who were referred for coronary angiography. NT-proBNP was assessed on admission and the next day. NT-proBNP values were related to the time duration from onset of symptoms until blood drawing with lowest values within 3 h and highest values 24-36 h after onset of symptoms (147 (64-436) pg/ml and 1099 (293-3795) pg/ml, respectively, p < 0.001). Highest values for NT-proBNP on admission were found in patients with NSTEMI compared to patients with STEMI and UAP (912 (310-2258) pg/ml) vs 262 (85-1282) pg/ml) vs 182 (74- 410) pg/ml; p < 0.001), but no difference was present between STEMI and NSTEMI the day after admission (1325 (532-2974) pg/ ml vs 1169 (555-3413) pg/ml; p = 0.676). In contrast NT-proBNP values remained unchanged in UAP (182 (74-410) pg/ml) vs 171 (53-474) pg/ml). CONCLUSION: The time interval from onset of symptoms to first blood collection is an important determinant for NT-proBNP values on admission in patients with an ACS and needs to be considered in clinical practice.
