Microplastics detected in most heart attack patients’ blood in startling new study

Patients experiencing severe heart attacks may have significantly higher concentrations of micro- and nanoplastics in their blood compared to individuals with stable heart conditions, according to new research.

Researchers led by Dr. Raffaele Marfella of the University of Campania Luigi Vanvitelli in Naples conducted the study, which was published in the European Heart Journal.

Polyethylene, a common material used in plastic bags and bottles, appeared in 97% of those patients who tested positive.

While notable, the findings should be considered in the broader context of environmental health hazards, said New York City-based Routhenstein, who was not involved in the study.

The findings align with previous research detecting microplastics in arterial plaque, Routhenstein noted, although she cautioned that the study has several limitations.

Health and environmental variables could also complicate the data. In the study, a history of smoking emerged as the single strongest predictor of detectable plastic particles in the blood.

To reduce potential risk, the dietitian recommends making targeted swaps to help limit daily exposure to microplastics.

She also urged taking extra precautions when preparing meals and drinking water.

She added, “Think of reducing plastic exposure as one piece of an overall heart-healthy lifestyle.”
