Doctors Find Evidence Microplastics Are Clogging Arteries, Leading to Heart Attacks and Strokes

SMRTR summary

University of California researchers fed microplastics to lab mice and discovered the particles dramatically increased artery-clogging plaque by up to 624 percent, but only in male mice. The microplastics activated genes in blood vessel cells that promote dangerous plaque formation, providing strong evidence these ubiquitous particles directly contribute to heart attacks and strokes rather than just correlating with cardiovascular disease.
