Microplastics Found in Artery Plaque

One of the most discussed microplastics papers of the last few years did not come from an environmental journal. It came from cardiology.

In 2024, researchers writing in The New England Journal of Medicine reported microplastics and nanoplastics in human arterial plaque. In that study cohort, patients with detectable plastic in plaque had a higher rate of heart attack, stroke, or death during follow-up than those without: Microplastics and Nanoplastics in Atheromas (NEJM, 2024).

As with any single study, this is not a final verdict on cause and effect for every population. It is a serious data point in an expanding literature that treats plastic particles as biologically relevant — not just an outdoor pollution story.

Why daily routines still matter

Research on blood and plaque sits beside more familiar exposure routes: bottled drinks, heated takeout packaging, and kitchen plastics. A related PNAS analysis of bottled water remains a useful companion read: Qian et al., PNAS, 2024.
