Plasma B-type natriuretic peptide levels predict postoperative atrial fibrillation in patients undergoing cardiac surgery. peptide and cardiac troponin I concentrations after adult cardiac surgery: association with postoperative cardiac dysfunction and 1-year mortality. Interpretation of plasma brain natriuretic peptide concentrations may require adjustment for patient's age. The results of the study were thoroughly analyzed in the reviewed article. The level of BNP concentration in 141 patients undergoing cardiac surgery was measured prior to operation and their comorbidities were examined against their BNP w1x. These results fully reflect all objectives of the study which were the evaluation of the BNP predictor in postoperative patients and the detection of connection between the level of this marker and the postoperative prognosis. In particular, the authors revealed that high level of BNP before intervention was found in patients with renal impairment, peripheral vascular disease and low ejection fraction. In patients with high inotropic use and longer ventilation time BNP level was statistically higher than in patients with routine postoperative period. However, there was no predicting value of BNP marker in patients with atrial fibrillation and infection in early postoperative period. In recent years, the study of neurohormonal activation and the role of BNP as a diagnostic and prognostic marker has taken a remarkable start w2x. BNP is a neurohormone which is synthesized in ventricular myocardium in response to increased wall stress. Pro-BNP marker (a terminal …
