Eptifibatide does not influence lymphocyte activation and CRP levels in patients with undergoing coronary angioplasty.

Inhibitors of the IIB-IIIA integrin are widely used to prevent stent thrombosis. Abciximab has been shown to attenuate the inflammatory response in patients undergoing PCI. Herein, we tested the effect of eptifibatide infused during PCI on peripheral lymphocyte activation and CRP levels before, and one month after the procedure showing no noticeable effect.

L-arginine attenuates lymphocyte activation and anti-oxidized LDL antibody levels in patients undergoing angioplasty.

Background: Patients with acute coronary syndromes exhibit evidence of peripheral T lymphocyte activation, elevated acute phase proteins and enhanced oxidative stress. Nitric oxide (NO) has been recognized as one of the relaxant factors synthesized and released by normal endothelium, and acts as a double-edged sword on the immune system. L-arginine ameliorates experimental atherosclerosis and restenosis as well as endothelial dysfunction.
