Evaluating the Effect of Intracoronary N-Acetylcysteine on Platelet Activation Markers After Primary Percutaneous Coronary Intervention in Patients With ST-Elevation Myocardial Infarction.

| Abstract |
During percutaneous coronary intervention (PCI), trauma occurs in the arterial endothelium, resulting in platelet activation and aggregation. As platelet aggregation may lead to coronary thrombosis, antiplatelet agents are essential adjunctive therapies in patients undergoing PCI. The aim of this study was to determine the effect of the intracoronary administration of high-dose N-acetylcysteine (NAC) for the evaluation of its antiplatelet effects in human subjects. In this triple-blind trial, 147 patients undergoing primary PCI were enrolled. Finally, 100 patients were randomized to receive high-dose intracoronary NAC (100 mg/kg bolus, followed by 10 mg·kg⁻¹·h⁻¹ intracoronary continued intravenously for 12 hours) (n = 50) or dextrose solution (n = 50). Platelet activation biomarkers were measured before and 24 hours after the procedure. Secondary end points, comprising all-cause death, reinfarction, and target-vessel revascularization, were assessed at 30 days and 2 years. In comparison with the placebo, NAC could not reduce the level of platelet activation biomarkers within a 24-hour period after its prescription. Major adverse clinical events at 30 days and 2 years were infrequent and not statistically different between the 2 groups. Our results revealed that NAC, compared with the placebo, did not provide an additional clinical benefit as an effective antiplatelet agent after PCI.
