Drug regime reverses heart disease in diabetics

By Andrew Stern

CHICAGO (Reuters) - Aggressive use of drugs to lower cholesterol and blood pressure helped reverse heart disease in people with diabetes, U.S. researchers said on Tuesday.

The three-year study of 499 Native American adults with type-2 diabetes showed that lowering blood pressure and cholesterol more than is usually recommended helped reverse thickening of the arteries and damage to the heart.

This is good news for everyone with diabetes, the researchers said -- especially Native Americans, who have high rates of the disease.

"These patients are two to four times more likely than people without diabetes to die from heart disease," said Dr. Elizabeth Nabel, director of the National Heart, Lung and Blood Institute.

"For the first time, we have evidence that aggressively lowering LDL cholesterol and blood pressure can actually reverse damage to the arteries in middle-aged adults with diabetes."

But other experts said the study, published in the Journal of the American Medical Association, did not resolve the debate over how low to go.

Advocates of aggressive treatment with cholesterol-lowering statins and blood pressure drugs argue the lower, the better, though conclusive data to support that view is lacking, wrote Duke University's Eric Peterson in a commentary.

"We know now that it's important to control risk factors for heart disease in people with diabetes, yet we don't know how far to aim," said Barbara Howard, who conducted the U.S. government-funded study with colleagues at MedStar Research in Hyattsville, Maryland.
