Do patients who suffer heart attack have more micro and nanoplastic in their blood? New study assessed

The Conversation reports on research published in the European Heart Journal showing that heart attack patients have notably higher levels of micro and nanoplastics in their blood compared to those without heart disease. Smokers were six times more likely than non-smokers to have these particles detected, and among those exposed to both smoking and high air pollution, every participant tested positive. Researchers propose that smoking may act as a delivery system, allowing microscopic plastic particles to more readily penetrate the lungs and enter the bloodstream. The study involved sixty-one participants and is observational, so it doesn't establish causation, but the pattern warrants further investigation.
