Exposure to bisphenol-A, a chemical found in many plastics and commonly known as BPA, may increase the chance of people's arteries narrowing, which can lead to a heart attack, according to a new study.
Researchers studied the BPA levels of 591 people who were suspected by their doctors of having severe coronary artery disease (CAD), a condition of narrowing arteries. They found that BPA levels were higher in those who were ultimately diagnosed with the disease.
The results add to a growing body of literature suggesting that BPA is harmful to human health, though the results "merit further investigation, but are not yet definitive enough to really worry people," said study author David Mosedale, chairman of the Metabonomics and Genomics in Coronary Artery Disease study. "There are a lot of things out there that we can consider harmful the longer we look," he said.
The people in the study were referred by their doctors to a CAD specialist because they exhibited some signs of the disease. The researchers used urine samples to measure the level of BPA in each person's body.
