Doctors studied 500 diabetic patients for three years.
Half the group had an aggressive LDL target of under 70, and they needed medication to get there. Results show those who took the aggressive route reduced the thickness of their arteries.
In contract those who stuck with traditional cholesterol goals had *increases* in artery thickness.
Experts say these findings in the Journal of the American College of Cardiology add to the debate over how low the goal for cholesterol levels should be.
