Microplastics Detected in All 17 Samples of Human Arteries

Detection of Microplastics in Human Arteries

According to НВ — Техно: Scientists from the Capital Medical University of China have detected microplastics in all 17 samples of human arteries examined after surgeries. The study covered coronary, carotid, and aortic arteries. The results regarding arteries with fatty plaques are particularly striking, where the concentration of microplastics was approximately twice as high as in aortic arteries without plaques. These results suggest that microplastics may have a more significant impact on the health of arteries with fat deposits.

Impact of Microplastics on Health

The concentration of microplastics in artery tissues was found to be higher than previously recorded in blood. The most common type of microplastic detected was polyethylene terephthalate (PET), which accounted for 73.7% of all identified particles. PET is used to make plastic bottles, food packaging, and synthetic clothing. Microplastics can enter the human body through food, drinks, and air, highlighting their prevalence in the modern environment.

Animal experiments indicate that microplastics may cause:

• oxidative stress
• cell damage
• disruption of fat and energy metabolism
• inflammatory reactions

A study conducted in 2024 observed 257 patients over 34 months, with polyethylene found in fatty plaques of arteries in 60%. Although it was noted that a higher content of microplastics is associated with an increased likelihood of heart attacks and strokes, a causal relationship has yet to be established.

The findings of the study were reported by Science Alert.

This discovery raises concerns about the impact of microplastics on human health, particularly regarding the cardiovascular system. Further research may help clarify whether microplastics are a risk factor for cardiovascular diseases.

The detection of microplastics in human arteries underscores serious environmental and medical issues related to pollution. As microplastics become increasingly prevalent in our lives, it is important to study their impact on human health and the possible mechanisms of interaction with the body. These results could spur new research and measures aimed at reducing the impact of microplastic particles on health and the environment.
