Intense diabetes treatment does not necessarily provide better treatment for fatal diseases like heart problems. Researchers from both the US and Australia have found it. However the Australian study shows that it can reduce the kidney problem in diabetes patients.
In a second largest study of its kind, the researchers have studied thousands of patients, to show no heart benefit from drastically lowering diabetics’ blood sugar levels. Thus the two study suggest to follow the recommended target levels. The Australian study has showed no difference in the number of heart attacks, strokes and heart-related deaths between groups who got intensive or standard care. Also, the US study records no such benefit. On the contrary it reported an unexplained higher number of deaths among those who were aggressively treated.
Heart disease is the cause of death for two-thirds of diabetics. Researchers tried to lower the sugar down to near-normal levels to see if that would protect the hearts of high-risk patients with Type 2 diabetes. The researchers suggests that there should be more focus on other strategies known to lower heart risks — diet, exercise and medications such as aspirin, cholesterol-lowering statins and blood pressure drugs.
In the two studies, researchers used a test that tracks average glucose levels over two to three months. For diabetics in the U.S., the recommended level is below 7. People without diabetes have levels around 5.
Dr. Elizabeth G. Nabel, director of the National Heart, Lung, and Blood Institute, in a statement said that severely lowering blood sugar appears to be too risky for diabetes patients at higher risk for heart problems. Her institute helped pay for the study.
