Summaries for patients. Chronic health problems seem to influence the relationship of blood sugar control and cardiovascular events in patients with type 2 diabetes.

摘要

Persons with type 2 diabetes are at high risk for cardiovascular events, such as heart attacks or stroke. Fortunately, this risk can be decreased with good medical care to control such risk factors as high blood pressure and high cholesterol. Although control of blood sugar improves the way patients feel and other diabetes complications, experts are not sure whether tight blood sugar control decreases the risk for cardiovascular events. Some studies show that it does and others do not. Experts think that the confusion may be because tight control benefits some patients but not others, depending on such factors as age and the presence of other health problems.
