Cancer risk from radiation during cardiac CT scans studied

An analysis based on computerized simulation models suggests that the lifetime risk of cancer associated with radiation exposure from a computed tomography (CT scan) coronary angiography varies widely, with the risk greater for women and younger patients, according to a study in the July 18 issue of JAMA .

Truth on postmenopausal hormone therapy and coronary disease

With each new publication of coronary artery disease (CAD) data from the Women's Health Initiative (WHI) study, the inevitable reaction is ,Why on earth did the WHI investigators claim in 2002-2004 that postmenopausal hormone therapy has deleterious effects on the risk for CAD, when, from the beginning, they were aware of the importance of the age factor in this clinical scenario".
