Abstract:
OBJECTIVE:To examine the serum levels of S100 calcium-binding protein A8/A9 complex (S100A8/ A9) in patients with acute coronary syndrome (ACS) and to explore the relation between the serum levels of S100A8/A9 and the degree of coronary lesion.
METHODS:A total of 126 patients with coronary heart disease were enrolled from Xiangya Hospital of Central South University between September 2010 and January 2011, which included 51 patients with unstable angina pectoris (UAP group, n=51), 50 patients with acute myocardial infarction (AMI group, n=50), and 25 patients with stable angina pectoris (SAP group, n=25). Twenty-five healthy volunteers were served as a normal control group (NC group, n=25). According to the coronary artery lesion area, ACS patients were also divided into a single-branch group, a double-branch group and a triple-branch group. Serum levels of S100A8/A9 were measured by enzyme-linked immunosorbent assay on the day when the patients admitted to the hospital and on the day after one-week treatment (UAP group + AMI group). The serum levels were compared among the various branch groups. The short-term prognosis in patients with ACS was investigated by phone follow-up after 3 months.
RESULTS:1) The S100A8/A9 level in the SAP group was significantly higher than that in the normal control group (P<0.05). The serum levels of S100A8/A9 in the UAP group and the AMI group were significantly higher than that in the SAP group (all P<0.05); There was no significant difference in the S100A8/A9 level between the UAP group and the AMI group (P>0.05); 2) After one-week standard treatment, the serum levels of S100A8/A9 in patients with ACS were significantly reduced compared with that at the admission (P<0.01), but it was still elevated compared with that in the normal control group (P<0.01); 3) The serum level of S100A8/A9 in the triple-branch group was significantly higher than that in the single-branch group and the double-branch group (both P<0.05); 4) The short-term prognosis in patients with ACS was not correlated with the serum level of S100A8/A9 (r=0.012, P> 0.05).
CONCLUSION:The serum level of S100A8/A9 is significantly elevated in patients with ACS, which might be positively correlated with the number of the coronary lesion branches.
