Microplastics and Atherosclerosis: Mechanisms
AI summary Read the abstract
This review examines the emerging evidence linking micro- and nanoplastic exposure to atherosclerosis, the buildup of plaques in blood vessel walls. Researchers found that these particles can enter the body through ingestion, inhalation, or skin contact and may promote cardiovascular damage through inflammation, oxidative stress, and immune activation. While direct causation has not been established, the study highlights the need for further research into how plastic pollution may affect heart and blood vessel health.
Microplastics are emerging as mediators in the interaction between environmental pollutants and cardiovascular health. Micro- and nanoplastics (MNPs) can enter the human body through ingestion, inhalation, or skin exposure, disrupting biological processes such as autophagy, inflammation, oxidative stress, immune activation, and vascular dysfunction. Therefore, MNPs might promote the development of cardiovascular diseases. The link between MNPs and cardiovascular diseases remains unclear, with no consistent data confirming a correlation between their concentration in tissues and disease onset. Continuously evolving analytical techniques to detect MNPs within human organs and tissues will help the design of prospective studies detailing the possible harm provided by different microplastics as well as their effects according to their physical properties and associated chemicals. In this review, we provide an update on the existing techniques for MNP detection and characterization to summarize the mechanisms linking these pollutants to human health, focusing on their effects on the cardiovascular system.

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.
Microplastics and Nanoplastics in Cardiovascular Disease
AI summary Read the abstract
This review summarizes existing research on tiny plastic particles called microplastics and nanoplastics and their possible links to heart and blood vessel disease. It covers how these particles may enter the bloodstream, studies finding plastic particles in human artery plaques, and possible biological effects like inflammation and blood vessel damage reported in human, animal and lab studies.
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.
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.
Emerging Links Between Cardiovascular Disease and Microplastics Exposure – A Narrative Review
AI summary Read the abstract
This review of existing research shows that tiny plastic particles called microplastics may be linked to heart disease - scientists have even found these particles inside the fatty buildups that clog arteries. When microplastics get into our bodies through food, water, and air, they appear to cause inflammation and damage blood vessels, which could increase the risk of heart attacks and strokes. People who eat lots of seafood, drink bottled water frequently, or work in certain industries may face higher exposure to these harmful plastic particles.
