Article Body: American Heart Association (AHA) spokeswoman Barbara V. Howard, PhD, says despite the confusing findings, it is clear that

keeping cholesterol under control is one of the best ways to avoid heart attack and stroke. Howard leads the AHA council on

nutrition, physical activity, and metabolism and is president of MedStar Research Institute in Hyattsville, Md. "Start with diet, exercise, and weight control -- and if that doesn't do it, medication probably will," she tells WebMD.

"There is no question that lowering cholesterol also lowers stroke risk.." Lewington and colleagues agree that the public health message is unambiguous. "Treatment should be guided principally by the definitive evidence from randomized trials, [showing] that Statins (Lipitor,

Zocor) substantially reduce not only coronary event rates but also total stroke rates in patients with a wide range of ages

and blood pressures," they write. High cholesterol is a major risk factor for death from heart disease, but its impact

on stroke death is less clear, a new analysis combining studies confirms. In one of the largest evaluations of the research examining cholesterol and mortality ever conducted, researchers found lower

total cholesterol to be strongly protective against death from heart attack for both men and women. Roughly , deaths from heart disease and , deaths from stroke were recorded among the almost , participants in

the studies. Among adults between ages and , a reduction in total cholesterol of mg/dL (or mmol/L) was associated with about a

% reduction in heart disease deaths. Among those aged to and to , respectively, mmol/L lower total cholesterol was associated with % and %

reductions in the risk of death from heart disease. "The message is clear with regard to heart disease," researcher Sarah Lewington, DPhil, of the University of Oxford, tells

WebMD. "If you are at risk for heart disease or have it, the lower your cholesterol, the better." Cholesterol and Stroke Death But important questions remain about the impact of cholesterol levels on death from stroke. While studies of cholesterol-lowering Statin Drugs (Lipitor, Zocor) unequivocally show the drugs to be protective against

stroke, most observational studies like the ones included in the latest analysis have failed to show a strong relationship

between blood cholesterol levels and death from stroke. Some have even shown low total cholesterol to be associated with an increased risk of death in elderly patients. "We don't really understand these findings, and they certainly invite future research," Lewington says. "But the evidence

from randomized trials clearly shows that lowering cholesterol with statins has a positive impact on stroke risk. No one is

saying that lowering cholesterol is bad news for strokes."
