Washington: Iron buildup may be a suitable marker of cardiac risk as it is much more prevalent in the kind of plaque in the heart artery which is more likely to promote an attack - and possibly sudden death.A team of researchers has found that Dual Energy Computed Tomography (DECT) and 3D computerised tomography (CT) micro-scans can detect excess iron in plaque, according to a Mayo Clinic statement.
Kantor predicts that probably five to 10 years will pass before novel diagnostic scanners to identify these plaques become available in cardiology clinics.The findings were presented at the American Heart Association`s Scientific Sessions 2010 in Chicago.IANS
