Method of imaging a cardiovascular disease with an anti-macrophage mannose receptor immunoglobulin single variable domain

The disclosure relates to the field of cardiovascular diseases. In particular, immunoglobulin single variable domains directed against macrophage mannose receptor (MMR) are provided that can be used in the diagnosis, prognosis and/or monitoring of cardiovascular diseases or as therapeutics. Also, the anti-macrophage mannose receptor (MMR) immunoglobulin single variable domains of the disclosure are useful at different stages of cardiovascular diseases, including post-infarction cardiovascular events. Further, the anti-macrophage mannose receptor (MMR) immunoglobulin single variable domains of the disclosure are particularly useful for the in vivo targeting and/or imaging of vulnerable atherosclerotic plaques.
