Studies: Intense treatment doesn't help diabetics

ATLANTA (AP) — Key results from a landmark federal study are in, and the results are disappointing for diabetics: Adding drugs to drive blood pressure and blood-fats lower than current targets did not prevent heart problems, and in some cases caused harmful side effects.

A decade ago, the federal government launched the three-part study to see whether intensely lowering blood sugar, blood pressure, or fats in the blood would reduce heart attacks and strokes in diabetics.

The first piece of the study — about blood sugar — was stopped two years ago, when researchers saw more instead of less risk with that approach. Now, the other two parts of the study are in.

What should diabetics do? Focus on healthy diets and lifestyles, and take tried-and-true medicines that doctors recommend now to control health risks, said several experts, including Dr. Clyde Yancy, a Baylor University cardiologist and president of the American Heart Association.

The studies were presented Sunday at an American College of Cardiology conference and published on the Internet by the New England Journal of Medicine.

They involve people with Type 2 diabetes — the most common form and the one rising because of the obesity epidemic. Diabetics have more than double the risk of dying of heart attacks or strokes than people without the disease.
