Micro-nano-plastics found in artery

A recent study has found the presence of micro- and nano-plastics in atherosclerotic plaque within the arteries of the neck. This discovery suggests a potential link between plastic pollution and cardiovascular disease.

Micro-nano-plastics found in artery

Researchers have made a significant finding in the field of cardiology, detecting micro- and nano-plastics in the arterial plaque of individuals with atherosclerosis. The study, published by the American Heart Association, examined samples from patients undergoing neck artery surgery. Using advanced techniques to analyze the plaque composition, the investigators identified plastic particles ranging from 1-100 micrometers in size.

The presence of these microplastics in the arterial plaque raises concerns about their potential role in cardiovascular disease. Atherosclerosis is a condition characterized by the buildup of fatty deposits and other substances within artery walls, leading to narrowing and hardening of the arteries. The introduction of plastic particles into this process may contribute to plaque instability and increase the risk of cardiac events.

Further research is needed to fully understand the relationship between micro- and nano-plastics and cardiovascular health. However, these findings suggest a need for increased awareness about the potential impact of plastic pollution on human health and the environment.
