Background: Plasma concentrations of intercellular adhesion molecule-1 [ICAM-1], vascular cell adhesion moleculc-1 [VCAM-1], and E-selectin may increase after percutaneous coronary intervention (PCI). Objective: The aim of this study was to assess whether anti-inflammatory treatment with steroid-eluting stents influenced concentrations of adhesion molecules after PCI in patients with unstable coronary syndromes. Methods: Consecutive patients with unstable coronary syndromes who were prospectively assigned to undergo implantation of a dexamethasone-eluting stent were compared with a control group of consecutive historical patients who received a similar non-drug-eluting stent in the period immediately preceding availability of the steroid-eluting stents. Circulating concentrations of adhesion molecules were measured before the procedure and at 6 and 24 hours after implantation. Results: The study included SO patients who received the dexamethasone-eluting stent (41 men, 9 women; mean [SD] age, 60 [9] years) and SO historical controls who received the non-drug-eluting stent (40 men, 10 women; mean age, 63 [11] years). Baseline values for the adhesion molecules were similar in the 2 groups: in patients who received the dexamethasone-eluting stent, mean (SD) values were 210 (41) ng/mL for ICAM-1, 637 (119) ng/mL for VCAM-1, and 46 (9) ng/mL for E-selectin; in the control group, the corresponding values were 218 (42), 618 (140), and 43 (10) ng/mL. Circulating concentrations at 24 hours were significantly lower in patients receiving the drug-eluting stent compared with controls for both ICAM-1 (279 [49] vs 338 [60] ng/mL, respectively; P = 0.001) and VCAM-1 (772 [163] vs 896 [207] ng/mL; P = 0.004). There was no significant between-group difference in E-selectin concentrations at 24 hours (60 [10] vs 56 [11] ng/mL). Conclusion: In this study, dexamethasone-eluting stents reduced plasma concentrations of ICAM-1 and VCAM-1 after PCI in patients with unstable coronary syndromes compared with historical controls.

Abstract

Background: Plasma concentrations of intercellular adhesion molecule-1 [ICAM-1], vascular cell adhesion moleculc-1 [VCAM-1], and E-selectin may increase after percutaneous coronary intervention (PCI). Objective: The aim of this study was to assess whether anti-inflammatory treatment with steroid-eluting stents influenced concentrations of adhesion molecules after PCI in patients with unstable coronary syndromes. Methods: Consecutive patients with unstable coronary syndromes who were prospectively assigned to undergo implantation of a dexamethasone-eluting stent were compared with a control group of consecutive historical patients who received a similar non-drug-eluting stent in the period immediately preceding availability of the steroid-eluting stents. Circulating concentrations of adhesion molecules were measured before the procedure and at 6 and 24 hours after implantation. Results: The study included SO patients who received the dexamethasone-eluting stent (41 men, 9 women; mean [SD] age, 60 [9] years) and SO historical controls who received the non-drug-eluting stent (40 men, 10 women; mean age, 63 [11] years). Baseline values for the adhesion molecules were similar in the 2 groups: in patients who received the dexamethasone-eluting stent, mean (SD) values were 210 (41) ng/mL for ICAM-1, 637 (119) ng/mL for VCAM-1, and 46 (9) ng/mL for E-selectin; in the control group, the corresponding values were 218 (42), 618 (140), and 43 (10) ng/mL. Circulating concentrations at 24 hours were significantly lower in patients receiving the drug-eluting stent compared with controls for both ICAM-1 (279 [49] vs 338 [60] ng/mL, respectively; P = 0.001) and VCAM-1 (772 [163] vs 896 [207] ng/mL; P = 0.004). There was no significant between-group difference in E-selectin concentrations at 24 hours (60 [10] vs 56 [11] ng/mL). Conclusion: In this study, dexamethasone-eluting stents reduced plasma concentrations of ICAM-1 and VCAM-1 after PCI in patients with unstable coronary syndromes compared with historical controls.
