Microplastics in Arteries Linked to Heart Disease Risk

Microplastics found in arterial plaque are linked to a higher risk of heart attacks and strokes, a new study reveals. Researchers analyzed plaque from the neck arteries of 257 people, finding tiny plastic particles in 58% of the samples. Those with microplastics had a significantly higher rate of heart attack, stroke, and death over nearly three years. While the study can't definitively link microplastics to these health issues, it highlights the potential health risks of plastic particles entering the body through food and water.

Concerns about the health effects of microplastics continue to rise. A new study reveals that individuals with microplastics in the plaque blocking their neck arteries are significantly more likely to experience a heart attack or stroke compared to those with plastic-free plaque.

Researchers analyzed plaque from the neck arteries of 257 individuals and discovered tiny plastic particles, mainly polyethylene and some polyvinyl chloride, in 58% of the samples. After nearly three years, those with microplastics in their plaque had a 4.5 times higher rate of heart attack, stroke, and death compared to those without.

While these findings are observational and cannot definitively link microplastics to these health issues, other unmeasured factors may also contribute. This study was published in the March 7, 2024, issue of The New England Journal of Medicine.

Polyethylene, used in making plastic bags and bottles, slowly breaks down and can be found in food and water, potentially explaining how microplastics enter the body.
