N-terminal pro-brain natriuretic peptide superiority for prognosis of major adverse cardiovascular events in patients with acute myocardial infarction without heart failure

Introduction/Aim. Many markers are used to evaluate the prognosis in patients with acute myocardial infarction (AMI). Researches are focused on available markers with high sensitivity and specificity. The aim of our study was to evaluate the prognostic value of N-terminal pro brain natriuretic peptide (NT-proBNP) and its superiority compared with other prognostic markers in patients with AMI. Patients and methods. Sixty-six patients with the diagnosis of AMI were enrolled in the study. The evaluated variables were: symptoms, cardiovascular risk factors, laboratory analyses (including NT-proBNP), GRACE risk score, electrocardiography, left ventricular ejection fraction (LVEF) and coronary angiography. Oneand six-month major adverse cardiovascular events (MACE) included: reAMI, heart rhythm disorders, acute heart failure, stroke, fatal event. Results. Patients with one-month and six-month MACE were older, had anterior AMI, higher levels of NT-proBNP, urea, creatinine, lower LVEF, creatinine clearance (CCr) and hemoglobin level. NT-proBNP is an independent predictor of short-term (p = 0.002) and long-term (p = 0.000) prognosis. Its cut point of 1,467 pg/ml is a significant independent predictor of one-month MACE and cut point of 996 pg/ml is a significant independent predictor of six-month MACE. Conclusion. NT-proBNP is a strong short-term and long-term predictive marker in AMI patients without heart failure.
