CHICAGO (AFP) - People who see images of their badly clogged arteries are more likely to lose weight and take anti-cholesterol drugs than people who don’t see severe disease on a computerized scan, researchers said Saturday. Two studies  showed that having a look at the real-time effect of one’s own lifestyle habits was a major motivator for change. The findings are important because convincing people to regularly take cholesterol-lowering drugs is a key hurdle in medicine and many patients are reluctant to make the changes needed until it is too late. “Seeing a coronary artery calcium scan gives patients a visual picture of how severe their disease is, and this picture seems to have a really big impact,” said Nove Kalia, one of the lead investigators for both studies.
