Patients who suffer heart attack have more micro and nanoplastic in their blood – new study

The Conversation is reporting on research in the European Heart Journal showing that heart attack patients have notably higher levels of micro and nanoplastics in their blood. The study uncovered a striking pattern: smokers were six times more likely to have detectable plastics in their heart's blood supply than non-smokers, and every participant who both smoked and experienced high air pollution showed evidence of these particles. Researchers propose that cigarette smoke may act as a delivery system, enabling microscopic particles to penetrate deep into the lungs and cross into the bloodstream. While the study was small and observational, it suggests smoking, air pollution, and plastic pollution may represent overlapping environmental threats to heart health.
