Abstract
Knowledge of macrophages in steady-state and diseased tissue is rapidly expanding, propelled by improved diagnostic capacity to detect and monitor cells in their native environments. In this review, we discuss implications for ischaemic heart disease and examine innate immune cell pathways that increase systemic leucocyte supply after myocardial infarction (MI). Acute MI alters the macrophage phenotype and supply chain from tissue resident to blood monocytes sourced from haematopoietic organs. That blood leucocytosis closely associates with cardiovascular mortality provides a strong motivation to understand why and how organ ischaemia alters cellular immunity.

Abstract
AIMS: HMG-CoA reductase inhibitors (statins) reduce cardiovascular mortality and morbidity in patients with stable coronary artery disease as well as acute coronary syndrome (ACS). It is unclear how rapidly the beneficial effects of statins occur in patients with ACS and whether these drug properties are related to lipid lowering. METHODS AND RESULTS Patients with troponin-positive ACS (n=35) were randomized to 20 mg/day rosuvastatin therapy or to placebo treatment. Anti-inflammatory effects of rosuvastatin measured by lymphocyte intracellular cytokine production were taken before initiation of treatment and on days 1, 3, and 42. Compared with placebo, rosuvastatin treatment significantly reduced plasma concentrations of pro-inflammatory cytokines TNF-alpha and IFN-gamma at 72 h. Rosuvastatin also induced a rapid and significant reduction of TNF-alpha and IFN-gamma production in stimulated T-lymphocytes at 72 h. When compared with placebo, rosuvastatin inhibited the Th-1-immune response measured at 72 h. CONCLUSION Rosuvastatin exerts rapid immunomodulatory effects on the level of T-cell activation in patients with ACS.
