Relationship between B-type natriuretic peptide and short-term prognosis in non-diabetic patients with ST-segment elevation myocardial infarction.

To investigate the differences of the B-type natriuretic peptide (BNP) levels in serum or plasma of the STEMI patients with different infarction sites. To explore the relationship between the BNP level and the short-term prognosis in patients with ST-segment elevation myocardial infarction (STEMI).A total of 216 STEMI patients were enrolled in this study from June 2012 to June 2014. All patients received coronary angiography (CAG). Based on electrocardiography (ECG) and CAG results, patients were divided into three groups. Group A included 80 patients with anterior/lateral wall myocardial infarction, group B included 76 patients with inferior/posterior wall myocardial infarction and group C included 60 patients with right ventricular myocardial infarction. We enrolled 53 patients with normal CAG results as Group D. BNP levels were compared among these groups. and according to BNP levels, all patients were subdivided into normal BNP group ( 0.05). The MACE prevalence in marked-higher BNP group was significantly higher than normal BNP group and mild-higher BNP group (p < 0.05).BNP levels can be used as a clinical indicator to predict short-term prognosis in STEMI patients.
