The high-dose statin treatment reduces neutrophil extracellular traps formation in patients with coronary artery disease

Abstract Background Neutrophil extracellular traps formation (NETosis) is currently considered as an important mediator in atherosclerosis and atherothrombosis. However, the impact of high-dose statin treatment, as potent cholesterol-lowering agents with pleiotropic effects, on NETosis in coronary artery disease (CAD) has been poorly described. Purpose We sought to assess whether in CAD patients the recommended statin treatment intensification is associated with changes in NETs-related markers and if such changes can alter fibrin clot properties. Methods 130 patients with advanced CAD, who did not achieve the target low-density lipoprotein cholesterol (LDL-C) were included. Before and at least 6 months after initiation of high-dose statin therapy (rosuvastatin 40 mg/d or atorvastatin 80 mg/d) citrullinated histone H3 (H3cit), myeloperoxidase (MPO) and neutrophil elastase (NE) as markers associated with NETosis were assessed in relation to C-reactive protein (CRP), thrombin generation, plasma clot permeability (Ks), clot lysis time (CLT), and fibrinolysis proteins. Results At baseline, NETosis did not differ depending on gender and cardiovascular risk factors but H3cit correlated with MPO (R=0.543, P
