Abstract:Objective To explore the effect of plasma N-terminal B type brain natriuretic peptide precursor (NT-proBNP) on the location of myocardial infarction and survival condition of the patients. Methods The clinical data of 96 patients with myocardial infarction in our hospital from June 2013 to June 2015 were retrospectively analyzed, and 30 people of health examination at the same period were selected into control group. The correlations of plasma NT-proBNP level with location of myocardial infarction and the patients’ survival condition were analyzed. Results In the patients with myocardial infarction the most frequently occurred lesions were inferior wall infarction (39.58%); the plasma levels of NT-proBNP from low to high were in patients with inferior wall infarction,anteroseptal wall infarction, anterolateral wall infarction, anterior wall infarction; the infarction area increased from inferior wall infarction, anteroseptal wall infarction, anterolateral wall infarction to anterior wall infarction. The plasma NT-proBNP levels in the patients with recurrence of myocardial infarction 1 and 12 months after discharge,heart failure and death were higher than those in the patients without, the differences were statistically significant (P< 0.05). Conclusions The level of plasma NT-proBNP is the highest in the patients with anterior wall infarction; and the higher the level of NT-proBNP, the larger the myocardial infarction area, the lower the survival rate.
