Micro-and Nano-Plastic Exposure as an Emerging Risk for Atherosclerotic Cardiovascular Disease
AI summary Read the abstract
Tiny plastic particles from our food, water, and even the air we breathe are showing up in human blood and blood vessels—including in the fatty buildup that causes heart attacks and strokes. This review pulls together existing research suggesting these particles may fuel heart disease by triggering inflammation and damaging blood vessels, though scientists haven't yet proven direct cause-and-effect. It's a wake-up call: everyday exposure to plastics, especially through household dust, packaged food, and synthetic textiles, may be a hidden and preventable risk to your heart health.
PURPOSE OF REVIEW: This review examines micro- and nanoplastic (MNP) exposure as an emerging risk factor for atherosclerotic cardiovascular disease, focusing on how individual-level exposures shaped by behaviours, micro-environments, and lifestyle factors contribute to cumulative internal dose and cardiovascular risk. RECENT FINDINGS: Micro- and nanoplastic (MNP) exposure occurs through multiple, continuous pathways, including inhalation of airborne particles, ingestion via food and drinking water, and contact with consumer products. Dietary intake varies substantially, with high concentrations reported in fruits, vegetables, and seafood. Indoor environments represent a dominant exposure setting due to elevated microplastic levels in household dust, synthetic textiles, and personal care products, while urban roadside environments further contribute to inhalation exposure. Marked global disparities are evident, with populations in low- and middle-income countries disproportionately affected due to concentrated plastic production, occupational exposures, and transboundary waste flows. Emerging biomonitoring and clinical evidence confirms the presence of MNPs in human blood, vascular tissues, and atherosclerotic plaques, indicating systemic exposure with potential cardiovascular implications. MNP exposure is a plausible contributor to CVD via inflammation, oxidative stress, and endothelial dysfunction. Despite limited causal evidence, findings highlight the need for improved exposure assessment, prevention strategies, and policy action.

Microplastics in atherosclerosis could exacerbate the cardiovascular risk: A systematic review
AI summary Read the abstract
Tiny plastic particles called microplastics — which we're exposed to through food, water, and air — may be building up in the fatty deposits that clog our arteries, potentially making heart disease worse. This review pulls together existing research on the topic and suggests these plastic bits could be an overlooked risk factor for heart attacks and strokes, though scientists are still working out exactly how much harm they cause. If confirmed, this means reducing plastic exposure in daily life could become an important part of protecting heart health.
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.

Tiny plastic particles from our environment—so small they can enter through the food we eat, the air we breathe, or even our skin—have been found lodged in heart and blood vessel tissue, and this review pulls together what scientists currently know about the damage they might cause, like inflammation, cell damage, and blood vessel problems that could contribute to heart disease. While researchers haven't yet proven these plastics directly cause heart disease in people, the growing evidence is concerning enough that the authors call for better tools to measure plastic exposure and more research into how to prevent harm. The bottom line: microplastics aren't just an environmental issue

AI summary Read the abstract
This review summarizes existing research on tiny plastic particles called microplastics and nanoplastics, which are found in food, water, and human tissue. It reports that these particles may contribute to clogged, hardened arteries by causing cell stress, inflammation, and blood vessel problems, though current evidence does not prove they cause heart disease in people.

AI summary Read the abstract
This review pulls together existing studies on tiny plastic particles found in blood vessels and artery plaque, some of which link their presence to higher rates of heart attack, stroke, and death. However, these studies show a connection, not proof that plastics cause these problems. Scientists say more research is needed before doctors should test for plastics or change how they treat heart disease.
