摘要
Background Myocardial impairment is often precipitated after burn. Previously, cardiac enzyme profile was often measured to determine myocardial injury, but was hardly specific. In this study, we investigated early changes of plasma N-terminal pro-brain natriuretic peptide （NT-proBNP） over time and its diagnostic value in burn patients. Methods 131 patients with heat burn were assigned to mild group （n = 19）, moderate group （n = 31）, severe group （n = 35） and extremely severe group （n = 35） based on their conditions. NT-proBNP and troponin I （cTnI） were continuously measured on days 1, 3, 5 and 7, respectively after admission. Results Significant differences were found on day 3, 5 and 7 between moderate burn group and mild burn group （P 0.05）; increase appeared earlier and lasted longer in severe group and extremely severe group as compared to mild and moderate groups （P 0.05）. Conclusions NT-proBNP is related to the severity of burn and can well reflect the status of myocardial injury in patients with severe burn, making it an ideal marker for myocardial injury in burn patients.
