Evidence, Mechanisms, and Clinical Implications of Microplastics and Nanoplastics As Emerging Cardiovascular Risk Factors: A Narrative Review
AI summary Read the abstract
This review examines growing evidence that micro- and nanoplastics may contribute to cardiovascular health risks, with researchers having found these particles in human artery plaques and blood clots. Evidence indicates that the particles can enter the bloodstream, trigger inflammation, damage blood vessel walls, and potentially increase the risk of heart attacks and strokes. While the evidence is not yet conclusive, the study highlights an emerging area of concern that warrants further investigation into how everyday plastic exposure may affect heart and blood vessel health.
This review comprehensively studied how microplastics and nanoplastics (MNPs) may affect heart and blood vessel health (cardiovascular diseases (CVDs)). These particles are found in the environment and can enter the human body through food, air, and skin contact. MNPs can travel through the bloodstream and build up in organs, including the heart and arteries. Studies in animals and humans suggest that MNPs may cause inflammation, damage blood vessels, disturb the normal function of the heart, and increase the risk of heart attacks and strokes. Researchers have also found MNPs in human artery plaques and blood clots. Current evidence of MNP on CVD is not fully conclusive. However, more research is needed to fully understand how much of a risk they pose. This review highlights the current knowledge, the possible health risks, the gaps in research, and what should be done next to better detect and manage these MNPs for public health safety.

Microplastic and Nanoplastic Contamination as a Novel Cardiovascular Risk Factor: A Narrative Review of Pathophysiological Mechanisms and Public Health Consequences
AI summary Read the abstract
This review pulls together existing research on tiny plastic particles found in our blood, organs, and even artery plaque. One study found people with these plastics in their artery plaque had a much higher risk of heart attack, stroke, or death. Scientists think the plastics may cause harmful inflammation and cell damage, though more research is needed to confirm this causes heart disease.
Micro- and nanoplastics: A new cardiovascular risk factor?
AI summary Read the abstract
This review examines the growing evidence that micro- and nanoplastics may pose risks to the heart and blood vessels. Studies in animals and cell cultures show that these tiny plastic particles can enter the bloodstream, trigger inflammation, promote blood clotting, and damage blood vessel walls. While human data is still limited, the review suggests that micro- and nanoplastic exposure should be considered a potential new risk factor for cardiovascular disease.
Microplastics and Nanoplastics in Cardiovascular Disease: An Emerging Cardiovascular Risk Factor
AI summary Read the abstract
Researchers reviewed mounting experimental and early clinical evidence that microplastics and nanoplastics cross epithelial barriers, accumulate in arterial plaques, cardiac tissue, and thrombi, and trigger oxidative stress and coagulation dysregulation, framing these particles as an emerging cardiovascular risk factor that warrants integration into disease prevention frameworks.
