Clinical value of rapid detection of plasma NT-proBNP levels on admission in patients with acute myocardial infarction

Objective To explore the clinical prognostic value of rapid detection for plasma NT-proBNP levels on admission in patients with acute myocardial infarction.Methods 56 patients with AMI were measured plasma NT-proBNP imediately in hospital,and then they were divided into A,B and C group according to NT-proBNP levels (A group:＜ 500ng/L,B group:500-2 000ng/L,C group:＞ 2 000ng/L).The incidence of major adverse cardiac events (MACE including congestive heart failure,malignant arrhythmia,cardiogenic shock and sudden cardiac death) in subjects were observed respectively during hospitalisation and 30 days.Results The three group subjects with different NT-proBNP levels presented different incidence of MACE(A group:1,0;B group:3,1;C group:8,6) at duration of hospital stay,30days (x2 =6.705,P =0.035 ; x2 =7.957,P =0.008).With the NT-proBNP levels rising in AMI paitents,the inciedence of MACE increased.The incidence of MACE in A,B and C group were 6.6％,18.18％ and 73.69％ respectively.Conclusion In AMI patients,plasma NT-proBNP levels could predict early MACE incidence,which has an important value to evaluate the early clinical prognosis.
