Raising good cholesterol has little impact: Study

Raising the blood levels of good cholesterol does nothing to reduce the risk of cardiovascular disease in patients already taking statins to lower their bad cholesterol, a federally-funded study has determined. Scientists at the National Heart, Lung, and Blood Institute (NHLBI), which led the study of some 3,400 Canadians and Americans, said Thursday they had prematurely terminated the trials after the results became clear. During the 32-month study, half the patients took extra doses of niacin, also known as vitamin B3, to raise their levels of good cholesterol, as well as a statin to lower their levels of bad cholesterol and triglycerides. The other half took a placebo instead of the niacin, while continuing with the statin treatment
