Washington: A new study has for the first time established a link between high levels of urinary Bisphenol-A (BPA) - a controversial chemical commonly used in food and drink containers - and severe coronary artery stenosis (narrowing of the arteries).A research team from the Peninsula College of Medicine and Dentistry (PCMD), University of Exeter, and University of Cambridge analysed data from 591 patients who participated in the Metabonomics and Genomics Coronary Artery Disease (MaGiCAD) study in Cambridgeshire, UK. They compared urinary BPA with grades of severity of coronary artery disease (CAD). The patients were classified into severe, intermediate or normal CAD categories based on narrowing of their coronary arteries measured using a technique called angiography, which is considered the gold standard method of diagnosis. In all, 385 patients were identified to have severe CAD, 86 intermediate CAD and 120 had normal coronary arteries.
