In a study by Martín-Reyes et al. [20], elevated plasma levels of monocyte chemoattractant protein-1 (MCP-1) and N-terminal pro-brain natriuretic peptide (NT-proBNP) were independently associated with greater complexity of coronary artery disease (CAD), as measured by the Syntax Score. Here, CCL2 is linked to coronary artery disorder.
