Workflow level release of microplastics, nanoplastics, and perfluoroalkyl and polyfluoroalkyl substances during simulated neurovascular interventions

AI summary · Read the abstract

A lab study found that catheters and devices used to treat brain blood clots and aneurysms can shed tiny plastic particles and "forever chemicals" (PFAS) into fluids during the procedure. This suggests patients may be exposed to these contaminants during treatment, highlighting a need for further safety testing of medical device materials.

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.

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.

Microplastic Particles and Infusion Therapy — Evidence, Implications, and Unanswered Questions

AI summary · Read the abstract

Researchers reviewed evidence that medical infusion devices and pharmaceutical containers release microscopic plastic particles directly into patients' bloodstreams, identifying a significant but underexamined exposure route and calling for updated industry standards and interdisciplinary research to assess clinical risks.
