A six-year study of people with type 2 diabetes found that intensively lowering blood pressure had a long-lasting effect in preventing heart attacks, strokes and deaths. But intensive blood sugar control didn’t produce those benefits, the researchers found. For the study, investigators followed nearly 8,500 participants of a completed diabetes trial. Some participants had had their blood pressure and blood sugar levels strictly controlled, while others had received standard care. The researchers wanted to assess the long-term effects of the intensive control, which ended when the trial concluded. "One of the points of doing this study was to see if lowering blood sugar for five years might, down the track, translate into protection against stroke and heart attack — it didn’t," said researcher Dr. Bruce Neal, a professor of medicine at the University of Sydney in Australia.
