Study: BPA May Increase Heart Disease Risk

Researchers are calling for government agencies to investigate a possible link between bisphenol-A and heart disease.

The endocrine disruptor, often found in the lining of food and soda cans, already has been linked to infertility, higher risks of breast and prostate cancers, diabetes and obesity.

Now, a new study found that “healthy people with higher urine concentrations of BPA were more likely to later develop heart disease,” according to a news release from Peninsula College of Medicine & Dentistry.

BPA can be detected in urine. In years past, it was prevalent in plastic containers and baby bottles. Many health officials warn not to store or reheat leftovers in plastic containers, which may contain BPA. People may also be exposed to BPA through drinking water, dental sealants, exposure to skin and inhaling household dust.

The latest study, published online in the journal Circulation, found that participants in the study who had higher urinary BPA concentrations later developed cardiovascular disease. But researchers “can’t be certain that BPA itself is responsible,” the news release states. More research is needed.

“This study strengthens the statistical link between BPA and heart disease, but we can’t be certain that BPA itself is responsible,” said lead researcher Professor David Melzer of the Peninsula Medical School. “It is now important that government agencies organize drug style safety trials of BPA in humans, as much basic information about how BPA behaves in the human body is still unknown.”

If BPA is causing an increase to the risk of cardiovascular disease, how much of an effect is difficult to estimate, said Professor Tamara Galloway of the University of Exeter, in the news release.

“However,” the senior author said, “it adds to the evidence that BPA may be an additional contributor to heart disease risk alongside the major risk factors, such as smoking, high blood pressure and high cholesterol levels.”
