N-terminal pro-B-type natriuretic peptide predicts long-term mortality but not stroke recurrence in acute ischemic stroke patients with a cardioembolic source (P1.051)
2015
OBJECTIVE:
To investigate the relationship of N-terminal pro-BNP (NT-proBNP) with each cardioembolic source, functional outcome, short-/long-term mortality, and stroke recurrence in stroke patients with cardioembolic mechanism.
BACKGROUND: There is little information on the relationship of B-type natriuretic peptide (BNP) with each cardioembolic source, long-term mortality, and stroke recurrence in the literature.
DESIGN/METHODS:
A total of 221 acute stroke patients with a cardioembolic source were included in this study. The study patients were classified into high or low BNP group based on the median value of NT-proBNP (蠅 or P- values < 0.05 were considered statistically significant.
RESULTS:
Median follow-up period was 20.5 months (range, 0.1 - 40.2 months). On the univariate logistic regression analysis, the good functional outcome (modified Rankin scale ≤ 2) at 6 months was negatively associated with advanced age, female gender, azotemia, left ventricular systolic dysfunction, NT-proBNP, and National Institutes of Health Stroke Scale (NIHSS). However, NIHSS alone remained a significant predictor of functional outcome on the multivariate analysis using the variables with P P P = 0.350 by log rank test). The multivariate Cox proportional hazards regression analysis showed that NT-proBNP, together with azotemia and NIHSS at admission, was a significant predictor of long-term mortality.
CONCLUSIONS:
Our study showed that the plasma level of NT-proBNP significantly predicted short-and long-term mortality although it was not associated with stroke recurrence in stroke patients with a cardioembolic source.
