Background:
Thrombomodulin (TM) is an endothelial cell surface thrombin-binding protein with anticoagulation ability by thrombin-mediated activation of protein C. An increase of plasma soluble TM level is reported to be associated with severity and worse outcome of coronary artery disease.
Hypothesis:
This prospective study investigated the relation of the elevated levels of plasma soluble TM and inflammatory and myonecrotic markers in patients undergoing percutaneous coronary intervention (PCI).
Methods:
Plasma levels of soluble TM, C-reactive protein (CRP), and creatine kinase and its MB isoenzyme were measured before and after PCI in 100 patients undergoing PCIs.
Results:
Peak TM levels after PCIs were significantly higher than baseline (3.39 +/- 1.63 vs. 2.90 +/- 1.57 ng/ml, p < 0.001). The peak TM levels after PCIs correlated significantly with the peak CRP and MB levels, and the maximal inflation duration (r = 0.423, p < 0.001; r = 0.212, p = 0.034; r = 0.307, p= 0.002, respectively).
Conclusions:
Soluble TM levels increase significantly after PCI. The elevation of the soluble TM after PCI shows better correlation with inflammation than myocardial injury, indicating an endothelial origin. Measurement of soluble TM could be useful and calls for further studies on the prognostic effects of this marker in this clinical condition.
