Background: Besides distal embolization of thrombus and plaque debris, locally increased inflammatory markers at the site of ruptured plaque in acute myocardial infarction (AMI) are thought to have an adverse impact on myocardial reperfusion during primary percutaneous coronary intervention (PCI). However, there is lack of data on such factors. Therefore, we investigated the presence of locally increased inflammatory and vasoactive factors in culprit coronary artery. Methods: We performed primary PCI with PercuSurge GuideWire system in 18 AMI patients. We collected blood samples from the femoral artery before PCI and from culprit coronary artery after first predilation while inflating the distal protection balloon and after completing PCI. We determined concentrations of C-reactive protein, soluble CD40 ligand, Interleukin (IL-6), serotonin, tissue factor, and factor VIIa. Results: While the concentrations of soluble CD40 ligand (2.84 ± 3.74 vs 0.98 ± 0.63 ng/mL, p = 0.004), IL-6 (33.67 ± 32.63 vs 17.08 ± 21.41 pg/mL, p < 0.001), serotonin (2.05 ± 0.76 vs 0.92 ± 0.60 ng/mL, p < 0.001), tissue factor (257.17 ± 84.34 vs 154.60 ± 87.99 pg/mL, p < 0.001) and factor VIIa (34.30 ± 27.30 vs 24.19 ± 28.00 ng/mL, p = 0.016) were significantly higher in the culprit coronary artery than in the femoral artery, CRP levels did not differ. The locally elevated concentrations of various factors were successfully reduced after multiple aspirations of blood using the PercuSurge GuideWire system. Conclusions: We found increased levels of soluble CD40 ligand, IL-6, serotonin, tissue factor and factor VII in the culprit coronary artery compared to those in peripheral blood. The clinical impact of such locally increased soluble factors in the culprit coronary artery needs to be investigated in further studies.
