ABSTRACT
<p><b>OBJECTIVE</b>To investigate the relationship between vasoactive factors and plaque morphology in patients with acute coronary syndrome (ACS).</p><p><b>METHODS</b>Intravascular ultrasound (IVUS) were performed and 7 serum vasoactive factors (sPE, tPA, MCP-1, IL-8, IL-6, sVCAM-1 and sCD40L) were measured through cytometric bead array, serum hs-CRP, HCY, glucose and lipid level were also determined in consecutively enrolled 56 patients with ACS. The changes of bio-factors were compared between vulnerable plaque and non-vulnerable plaque groups, AMI and UA patients, and patients with or without plaque rupture.</p><p><b>RESULTS</b>Biomarkers were similar between patients with unstable angina pectoris and AMI. hs-CRP [(18.9 +/- 4.9) mg/l vs. (5.8 +/- 3.6) mg/L)] and IL-6 [19.5 pg/ml (9.2 - 44.6 pg/ml) vs. 5.3 pg/ml (2.3 - 13.4 pg/ml)] were significantly higher in the group of vulnerable plaque (P < 0.05) compared to non-vulnerable plaques group. sCD40L [(474 +/- 126) pg/ml vs. (238 +/- 35) pg/ml], sPE [(107.2 +/- 39.9) microg/ml vs. (49.1 +/- 5.6) microg/ml] and MCP-1 [(132 +/- 18) pg/ml vs. (127 +/- 13) pg/ml] were significantly increased in the plaque rupture group than that in non-plaque rupture group (all P < 0.05). Increasing of sCD40L, MCP-1, sPE and TC were independent risk factors for plaque rupture.</p><p><b>CONCLUSIONS</b>IL-6 and hs-CRP are biomarkers for vulnerable plaques and diagnosis of acute myocardial infarction. sCD40L, MCP-1 and sPE may serve as the potential markers predicting plaque rupture in patients with ACS.</p>
