Input: Question: Are cXCL4 Plasma Levels Associated with the Extent of Coronary Artery Disease or with Coronary Plaque Morphology?
Answer: While CXCL4 may be present and active within the arterial wall, local increase of CXCL4 may not translate into systemically elevated CXCL4 levels. Further studies will have to test whether CXCL4 may still represent a suitable therapeutic target in human atherosclerosis.

no
