Scientists find microplastics lodged in more than 50% of plaques from clogged arteries

by DailyHealthPost Editorial

Imagine for a moment your body as a complex network of rivers and streams. These rivers – your arteries and veins – are essential for transporting life-sustaining blood to every corner of your body. Now, imagine finding out that these vital waterways are polluted, not with chemicals or waste, but with something as mundane as plastics. That’s exactly what recent studies are suggesting – our arteries may be clogged with the same materials used to make our water bottles and grocery bags.

It’s a revelation that’s as concerning as it is surprising. Over 50% of arterial plaques, the blockages that can lead to heart attacks and strokes, are now found to contain plastic particles. These aren’t large pieces, but microplastics, so tiny they can travel through our bloodstream and embed themselves deep within our bodily tissues.

Recent Study Reveals Startling Data

A landmark study published in the New England Journal of Medicine has catapulted the issue of microplastics into the limelight of public health concerns. The study, which followed hundreds of patients, found that a staggering 60 percent had microplastics lurking within the plaques of their arteries.


The Ubiquity of Plastics and Human Health

We live in an age where plastics are virtually inescapable. They are in our homes, our workplaces, and even in the food we eat and the air we breathe. It’s no wonder then that these materials are making their way into our internal systems. But what does this mean for our health?

Understanding the Health Impact

Before we dive into the gritty details, let’s get one thing clear: the plastics we’re talking about are not the kind you can see. Microplastics are microscopic particles that, once they enter the body, can cause a cascade of health issues. They can trigger inflammation, which is a known precursor to a multitude of diseases, including atherosclerosis – the hardening and narrowing of the arteries.

When our arteries are compromised, blood flow is restricted, and the risk of heart attacks and strokes skyrockets. The connection between microplastics and cardiovascular disease is still being explored, but the evidence is mounting, and it’s pointing towards a relationship we cannot afford to overlook.

How Microplastics Enter the Body

Let’s break down how these microplastics are getting into our systems. It’s a multifaceted problem, with numerous sources contributing to our daily intake of these tiny particles. They can come from a variety of everyday activities that may impact our blood circulation and overall health.

  • The breakdown of larger plastic items in the environment.
  • Microbeads found in personal care products like exfoliants and toothpaste.
  • Synthetic fibers released when washing clothes made from materials like polyester and nylon.
  • Plastic packaging that can shed particles into the food it contains.
  • Airborne dust from the degradation of plastic items in our surroundings.

Because these particles are so small, they can penetrate the body’s natural defenses and find their way into our bloodstream. From there, it’s a short journey to the heart and the arterial walls, where they can become part of the plaques that spell trouble for cardiovascular health.

Therefore, understanding the various pathways through which microplastics enter our bodies is essential. It’s the first step in taking control of our exposure and, in turn, our health.


Associations with Cardiovascular Illness

When we talk about cardiovascular illness, we’re referring to a range of conditions that affect the heart and blood vessels. Microplastics are now suspected to be a silent contributor to these diseases. They can set off inflammation, which is known to damage the delicate inner lining of blood vessels, leading to the buildup of plaques. These plaques can narrow arteries and, if they rupture, can cause clots that may lead to heart attacks or strokes.

It’s not just about the physical presence of plastics in the arteries, but also about the chemicals they leach. These substances can disrupt the body’s hormonal balance and have been linked to obesity, diabetes, and hypertension – all risk factors for heart disease. This makes the conversation about microplastics not just an environmental concern, but a pressing health issue.

Unveiling the Study’s Findings

  • Over 50% of arterial plaques in patients studied contained microplastics.
  • The most common plastics found were polyethylene (used in packaging) and PVC (used in pipes and building materials).
  • Patients with microplastics in their plaques had a higher incidence of heart attacks and strokes.

The study in question followed patients over a period of 34 months, revealing a correlation between the presence of microplastics in arterial plaques and the occurrence of serious cardiovascular events. While correlation does not imply causation, this association is a red flag that signals the need for further research and immediate public health action.

The findings are a wake-up call, urging us to re-evaluate our relationship with plastic materials and their pervasive role in our daily lives. We now know that our exposure to these materials can have direct implications for our heart health.

Analysing the Italian Research Results

The Italian research that brought these findings to light was a comprehensive analysis that meticulously tracked the presence of microplastics in patients with clogged arteries. The study’s methodology was robust, involving prospective, multicenter research to ensure the findings were not isolated to a specific region or group of people.

Relation Between Microplastics and Artery Plaques

The relation between microplastics and artery plaques is not merely incidental. Plaques are made up of fats, cholesterol, calcium, and other substances found in the blood. When microplastics enter the bloodstream, they become part of this mix, contributing to the size and potentially the stability of the plaques. Unstable plaques are more likely to break apart and cause blockages, leading to heart attacks or strokes.


This discovery is particularly troubling because it suggests that our exposure to plastics could be directly influencing the progression of arterial diseases. It also raises questions about the long-term effects of microplastics on our vascular health and the potential for these particles to contribute to other diseases.

Examining the Culprits

It’s important to identify the types of plastics that are most commonly found in these arterial plaques. This knowledge can help us target the biggest offenders and reduce our exposure to them.

Common Sources of Microplastics

Everyday items are the main culprits when it comes to microplastic pollution. Here are some of the most common sources:

  • Single-use plastics, like water bottles and shopping bags, which break down into smaller pieces.
  • Clothing made from synthetic fibers that shed microplastics with each wash.
  • Beauty products with microbeads, although many countries are now banning these.
  • Food packaging, which can shed microplastics that contaminate our food.
  • Industrial processes that release plastic dust into the air.

These sources are so ingrained in our daily routines that avoiding them entirely can be challenging. However, by being aware of them, we can start to make more conscious choices that can help reduce our overall exposure.

The Role of Polyethylene and PVC in Plaques

Specifically, polyethylene and PVC have been highlighted as the most prevalent plastics found in arterial plaques. Polyethylene is the most commonly produced plastic and is used in a wide array of packaging materials. PVC, or polyvinyl chloride, is used in everything from pipes to building materials and can release harmful phthalates – chemicals that have been linked to a range of health issues.

The Path to Better Health

While it’s nearly impossible to eliminate all exposure to plastics, there are effective strategies we can adopt to minimize our risk.


Preventative Measures to Minimize Plastic Exposure

To start reducing our plastic footprint and its potential health risks, consider the following:

  • Choose glass or stainless steel containers over plastic ones, especially for food and drink storage.
  • Opt for clothing made from natural fibers rather than synthetic ones to reduce the release of microfibers during laundry.
  • Support and advocate for environmental policies that aim to reduce plastic waste and improve recycling programs.
  • Be mindful of plastic use in your daily life and seek out alternatives whenever possible.
  • Participate in community clean-up efforts to help reduce the amount of plastic that can break down into microplastics.

Implementing Healthier Lifestyle Choices

Eating a balanced diet rich in fruits, vegetables, and whole grains, getting regular physical activity, and finding ways to manage stress can all help keep your arteries clear and your heart strong. A heart-healthy lifestyle is your best defense against the myriad of threats facing our cardiovascular system today.


It’s natural to have questions about microplastics and their impact on our health. Here are some answers to the most commonly asked questions:

What Are Microplastics and How Do They Affect Health?

Microplastics are tiny plastic particles, usually smaller than 5 millimeters, that can come from a variety of sources, including larger plastic debris that breaks down, microbeads in personal care products, and synthetic fibers from clothing. They can enter the human body through ingestion or inhalation and have been found in various organs, including the heart and brain. In the body, they may cause inflammation and contribute to the development of diseases, such as cardiovascular disease.

How Can I Reduce My Exposure to Microplastics?

To reduce exposure to microplastics:

  • Avoid single-use plastics and opt for reusable alternatives.
  • Choose products with natural ingredients and without microbeads.
  • Wash synthetic clothes less frequently and use filters to capture fibers.
  • Filter tap water, especially if you live in an area with high plastic pollution.
  • Support and participate in environmental conservation efforts.

These steps can help you limit the amount of microplastics you come into contact with and potentially ingest.


What Foods or Products Are Known to Contain Microplastics?

Microplastics have been found in a variety of foods and products, including:

  • Seafood, especially shellfish, as they can ingest microplastics from the ocean.
  • Bottled water, which can contain microplastics shed from the packaging.
  • Table salts, particularly sea salts that may be contaminated with microplastics.
  • Beer and other beverages that may be contaminated during the production process.
  • Personal care products like facial scrubs and toothpaste that contain microbeads (though many countries have banned these).

Being aware of these sources can help you make more informed choices about the products you consume and use daily.
