Recently, research conducted by a leading institute revealed that microplastics in blood clots can increase the risk of death by heart attack. When these microplastics are present in blood clots, they can contribute to the formation of plaque, which blocks blood flow and results in heart attacks. A study published in EBioMedicine and research conducted by scientists in China have highlighted the significant presence of microplastics in blood clots from major blood vessels, such as those in the heart and brain.
A blood clot is a gel-like clump of dried blood in a blood vessel formed in response to an injury. It stops bleeding by plugging the injured vessel and facilitates healing in the area. However, when microplastics become embedded in these blood clots, they can cause the spontaneous formation of clots, which can obstruct blood flow in the blood vessels and result in cardiovascular problems. Now let's understand in detail how microplastics can cause heart attacks.
Process of How Microplastics in Blood Clots Increase Heart Attack Risk:
Entry into the Body: Microplastics, tiny plastic particles less than 5mm in size, can enter the human body through various sources such as contaminated food, water, air, and even certain consumer products like cosmetics and personal care items.
Circulation in the Bloodstream: Once inside the body, these microplastics can make their way into the bloodstream. They circulate through the blood vessels and can come into contact with various components of the blood.
Interaction with Blood Components: Microplastics can interact with blood cells and proteins, potentially altering normal blood functions. Studies have shown that these particles can inhibit the formation of fibrin clots, which are essential for stopping bleeding.
Formation of Blood Clots (Thrombi): In some cases, microplastics can become embedded in blood clots, or thrombi. These clots can form in major arteries, including those supplying the heart, brain, and legs.
Risk of Cardiovascular Events: When these clots obstruct blood flow, they can cause severe health issues. If a clot blocks a coronary artery, it can lead to a heart attack. Similarly, a clot blocking a cerebral artery can result in a stroke.
Conclusion:
The presence of microplastics in blood clots poses a significant health risk by contributing to the formation of plaque and obstructing blood flow, which can lead to serious cardiovascular events like heart attacks and strokes. Understanding the pathways through which microplastics enter the body and interact with blood components is crucial for developing strategies to mitigate their impact on human health. Continued research in this area is essential to address and reduce the risks associated with microplastic contamination.
