Study Detects Microplastics in 84% of Severe Heart Attack Patients' Coronary Blood

Summary
Researchers found microplastics and nanoplastics in the coronary blood of 84% of STEMI patients, versus 40% in chronic ischemic heart disease and 32% in patients with normal coronary arteries.
The 61-patient Italian study sampled blood directly from heart-supplying vessels and found the heart attack group carried a broader mix of plastics, with polyethylene detected most often.
Smoking and air pollution showed the strongest links: smokers were six times more likely to test positive, and every patient who both smoked and had higher pollution exposure carried plastic particles.
Patients without smoking or higher pollution exposure had a 12.5% detection rate, supporting researchers' view that lungs may be a key route for plastics entering the bloodstream.
The study did not prove plastics cause heart attacks, but higher inflammatory markers and prior evidence of plastics in artery plaques add to concerns over cardiovascular risks.

Microplastics and Cardiovascular Disease: New Evidence, Health Risks, and Strategies for Mitigation
Overview
Recent research has revealed that microplastics and nanoplastics are present in human heart tissue and arteries, especially within arterial plaques of patients with cardiovascular conditions. These particles, such as polyvinyl chloride, are linked to a higher risk of heart attacks and other cardiovascular events, suggesting they may be a new risk factor beyond traditional causes. Microplastics can enter the body mainly through inhalation and ingestion, eventually reaching the cardiovascular system. Their presence may trigger inflammation and oxidative stress, highlighting the urgent need for further research and public health action to address this emerging threat.
