Abstract
Background: Periostin (PN) concentration increases in the blood of patients after acute myocardial infarction (AMI) and affects the process of cardiac remodelling leading to myocardial fibrosis. This study aimed to evaluate the correlation between serum PN levels with cardiac function and short-term prognosis (after 3 months of AMI) in patients with non-ST-elevation AMI. Methods: Case-control study, 3-month follow-up. 35 patients with AMI and 37 healthy people were chosen as the control group. In the group of patients, serum PN was obtained from day 5 - 7 of the disease. The correlation between PN and TIMI, GRACE scores, body mass index (BMI), laboratory findings, and 3-month post-MI data including pro B-type natriuretic peptide (pro-BNP) and echocardiographic parameters. Results: Serum PN levels increased significantly when patients had AMI, negatively correlated with ejection fraction (EF) (r = - 0.462, p = 0.005), positively correlated with left ventricular end-diastolic diameter (LVDd) (r = 0.413, p = 0.014). Conclusions: AMI increases serum PN levels, and PN can be used to predict cardiac function 3 months after MI in patients with non-ST elevation AMI. Key words: periostin, acute myocardial infarction.
