A Comprehensive Review on Micro and Nanoplastics-Mediated Cardiovascular Complications
AI summary Read the abstract
This comprehensive review examined how micro- and nanoplastics contribute to cardiovascular complications, detailing mechanisms including oxidative stress, inflammatory cytokine activation, endothelial dysfunction, and the transport of co-contaminants that damage cardiac and vascular tissue. With plastics now detected in human blood and arterial plaques, understanding their role in cardiovascular disease has become a critical frontier in environmental health research.
In the modernized world, society produces hundreds of millions of plastics, including their use in consumer commodities, packaging, and dressing. An estimate currently provided states that 364 million tons of plastics are generated yearly and that this may increase...

The effects of microplastics and nanoplastics on cardiovascular disease: mechanisms and perspectives
AI summary Read the abstract
This review synthesizes current evidence on how microplastics and nanoplastics (MNPs) may contribute to cardiovascular disease, examining their presence in blood, atherosclerotic plaques, thrombi, and heart tissue. Experimental studies point to oxidative stress, mitochondrial dysfunction, inflammation, and fibrotic remodeling as plausible mechanisms linking MNP exposure to heart disease, though causal relationships in humans remain unproven and standardized detection methods are still lacking.
Microplastics and nanoplastics: tiny threats for cardiovascular diseases?
AI summary Read the abstract
Tiny plastic particles from our environment, called microplastics and nanoplastics, are showing up in human blood vessels, and one study found that patients with these particles in their artery plaques had a 4.5 times higher risk of heart attack, stroke, or death compared to those without. This review paper pulls together current research suggesting these plastic fragments may trigger inflammation and damage blood vessels, though scientists still need larger studies to confirm plastics are actually causing heart problems rather than just being present alongside them. While we wait for more answers, this adds plastic pollution to the growing list of everyday environmental exposures, like air poll
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.
Cellular and Animal Toxicities of Micro- and Nanoplastics
AI summary Read the abstract
Researchers reviewed evidence from cell and animal studies on the toxic effects of micro- and nanoplastics, finding that these particles can cause inflammation, oxidative stress, and organ damage in laboratory models, raising concern about what chronic low-level human exposure might mean for long-term health.
