If you read the article:

>A study of more than 200 people undergoing surgery found that nearly 60% had microplastics or even smaller nanoplastics in a main artery1. Those who did were 4.5 times more likely to experience a heart attack, a stroke or death

They weren't comparing against people with no microplastics whatsoever, only the ones that had no detectable amounts in their arteries.

My bad, I assumed if you have plastics on your body then you have it in your arteries. If not then I want to know how to not get that stuff in my arteries.

Put another way, say you and I both have occluded arteries, and we are both inhaling and ingesting microplastics because they're inescapable. I have plastic in my clogs and you do not. What are you doing differently?

I wonder about the strength of the argument. It’s a 80 versus 120 people study, with the adverse events being quite low chance events and the risk very much driven by age and lifestyle.
