BPA Linked to Narrowed Arteries

A new study has found a correlation between higher bisphenol-A levels and constricted arteries, reports Amanda L. Chan of the Huffington Post. Known formally as "artery stenosis," constriction of the arteries is often a precursor to chest pains, and in severe cases, heart attack as blood flow is restricted to a miniscule amount. Writes Chan:

Researchers examined the urinary BPA levels and artery narrowing of 591 people who participated in the Metabonomics and Genomics Coronary Artery Disease in the United Kingdom. They found that 385 of the study participants had severe artery narrowing, 86 had "intermediate" artery narrowing and 120 didn't have narrowed coronary arteries.

The researchers found an association between higher urinary BPA levels and increased risk for severe narrowing of the arteries.

This is not the first recent study which has shown a correlation between bisphenol-A and heart disease, and Chan points out that earlier this year, the same team published an article in the journal Circulation which found a correlation between high BPA levels and coronary disease. One of the researchers working on the study commented that:

"Our latest study strengthens a growing body of work that suggests that BPA may beadding to known risk factors for heart disease," study researcher David Melzer, a professor of epidemiology and public health at the Peninsula College of Medicine and Dentistry at the University of Exeter, said in a statement. "Full proof will be very difficult to get, as experiments on this in humans are not feasible."
