Prevention of heart disease among diabetics

We are told today about the early stoppage of NIH sponsored research (the ACCORD study) to reduce heart disease deaths among diabetics by strict and aggressive control of blood sugar levels. Early results have shown that aggressive treatment is more harmful than moderate approaches. Now we need to learn why, and how to provide better care of diabetics. Clearly primary prevention by encouraging better weight control, more exercise, and better diets are preferable to fixing the problem after it occurs. It is too bad that behavioral science has so little to offer.
