Microplastics and nanoplastics increase major adverse cardiac events in patients with myocardial infarction.

Summary: Tiny plastic particles are finding their way into the human heart. A new study examined patients who had suffered heart attacks and discovered that those with higher levels of polyvinyl chloride (PVC) microplastics in their coronary arteries faced a much harder road to recovery. These plastics appear to trigger significant inflammation within the blood vessels. Consequently, patients with high PVC levels were more than twice as likely to suffer another major heart event or death compared to those with lower levels. This suggests that plastic pollution isn't just an environmental issue; it is a direct risk factor for heart health.
