Objective: To study the serum laminin (LN) and fibronectin (FN) changes in acute coronary syndromes (ACS), and explore the role of them in assessing the severity of ACS. Methods: This study included 46 ACS patients [25 with acute myocardial infarction (AMI) and 21 with unstable angina (UA)], 51 stable angina (SA) patients and 47 people without CHD as controls. Serum levels of LN, FN, fibrinogen and blood fat were assessed. Coronary angiography were performed on 49 of them. Results: The serum concentration of LN was lower in ACS patients [(85.20±27.57) ng/mL], higher in SA patients [(116.80±28.80) ng/mL] as compared to that in the control group [(100.06±29.96) ng/mL], with significant difference among the groups (P<0.05). No difference was found in FN among the three groups. However, the subgroup analysis in the group with ACS showed that the serum concentration of FN was significantly higher in UA patients [(229.60±121.39) μ;g/mL], and lower in AMI patients [(108.31±47.12) μg/mL]. The serum LN and FN concentration could respectively enter the logistic regression equations of ACS patients and US patients. Neither LN nor FN concentration was correlated with narrowing of coronary artery of angiography. Conclusion: Serum LN and FN level may be a useful indicator for stability of atherosclerosis plaque in coronary arterial disease patients, but could not predict the extent of narrowing in coronary angiography.
