The New York Times published a piece on December 9, "Cholesterol-Fighting Drugs Show Wider Benefit" reporting on a study that showed that cholesterol-lowering drugs, statins, can significantly lower the risk of heart attacks, stroke and death, even in people with low cholesterol levels:

"The study, presented Sunday at an American Heart Associationconvention in New Orleans and published online in The New England Journal of Medicine, found that the risk of heart attack was more than cut in half for people who took statins."

The study was paid for by AstraZeneca, which makes the drug tested, rosuvastatin, sold as Crestor. The TV networks absolutely loved this story, as you can see from the CBS News video and NBC Nightly News

So we did an online search: Crestor and "Class-Action" Lawsuit.
