OBJECTIVE: To investigate the changes in serum Myeloid-Related Protein 8/14 (MRP8/14) and Eosinophil Cationic Protein (ECP) levels in patients with different types of coronary artery diseases (CAD) and assess the value of MRP8/14 and ECP detection in predicting CAD.
METHODS: 178 patients were divided into CAD group including unstable angina pectoris (UAP), acute myocardial infarction (AMI), and stable angina pectoris (SAP). Thirty-six individuals with normal coronary artery served as the control group. Serum MRP8/14 and ECP were measured by ELISA. The severity of coronary artery stenosis was assessed by the numbers of involved coronary artery branches and the sum of Gensini scores.
RESULTS: The MRP8/14 levels were significantly higher in AMI and UAP group than SAP and control group (P < 0.05). The levels of MRP8/14 in AMI group were also obviously higher than UAP group (P < 0.05). The ECP levels were obviously increased in AMI group, but there was no difference between SAP and UAP group (P > 0.05). The ECP was significantly increased in three impaired coronary arteries and obviously correlated with Gensini score (P < 0.01), whereas the MRP8/14 was obviously positively correlated with CRP (P < 0.01).
CONCLUSIONS: Increased MRP8/14 levels suggest the instability of the atherosclerotic plaque. ECP reflects the severity of coronary arteries stenosis, predicting atherosclerosis burden. They may become the new biomarkers of CAD.
