Microplastics Detected in Blood of Most Severe Heart Attack Patients, Study Shows
A study of 61 patients undergoing coronary angiograms found micro- and nanoplastics in the blood of about 84% of those with active severe heart attacks, with polyethylene most commonly detected; researchers stress that this shows association, not causation, and smoking and air pollution complicate interpretation. The authors suggest reducing daily plastic exposure (e.g., using glass containers) as part of a broader heart-healthy lifestyle.
