Micro-nano-plastics found in artery

Researchers have found micro- and nano-plastics embedded within atherosclerotic plaques in the neck arteries of individuals. This discovery has significant implications for understanding the potential role of plastic pollution in cardiovascular disease.

Micro-nano-plastics found in artery

A recent study published by American Heart Association researchers revealed the presence of micro- and nano-plastics in artery-clogging plaque found in the neck arteries of individuals. The investigation, which utilized advanced imaging techniques, identified these plastics within atherosclerotic plaques, highlighting their potential involvement in cardiovascular disease.

The findings suggest that exposure to plastic pollution may have unforeseen consequences for cardiovascular health. Atherosclerosis, characterized by the buildup of fatty deposits and cholesterol-rich material in artery walls, is a major risk factor for heart attacks and strokes. The presence of micro- and nano-plastics within these plaques raises questions about whether plastic particles play a role in promoting or exacerbating atherosclerotic disease.

Further research is needed to determine the mechanisms by which plastics may contribute to cardiovascular disease and to assess their potential impact on public health.
