BPA is a chemical widely used in plastic food and drink containers, and a new study published in PLOS One suggests that high levels of the chemical may actually contribute to the narrowing of coronary arteries that lead to heart disease.


For the study, researchers analysed data from 591 participants in a UK study looking at the causes of coronary artery disease (CAD). In total, 385 patients had severely damaged arteries, while 86 were moderately affected and 120 were healthy.

Even more interesting is the fact that high levels of bisphenol-A (BPA) were found in the urine of patients with severe damage to the arteries supplying blood to the heart, which causes symptoms like chest pain and tightness, and can even lead to a heart attack.

The new findings add weight to previous studies that had already linked the chemical to an increased risk of heart disease.
