Gold nanoparticles in cardiovascular imaging.

Although originally applied in the field of oncology, recent results have illustrated the considerable potential of gold nanoparticles (GNPs) in the imaging of cardiovascular diseases (CVDs). CVDs represent the leading cause of mortality and disability in the world. The principal cause underpinning CVDs is atherosclerosis, which develops into mid and large blood vessels, often leading to severe complications. Thanks to their unique physicochemical properties, GNPs have drawn much attention from the research community in cardiovascular imaging. Thus, the optical properties of GNPs have led to their utilization as contrast agents for optical or X-ray imaging modalities allowing the detection of atherosclerotic plaques, intravascular thrombus, or fibrotic tissue. In this study, we detail the most promising preclinical scientific progresses based on the use of GNPs for imaging in cardiovascular field and their improvements for a potential clinical application.
