[Hypoglycemia and cardiovascular risk].

Intensive glycemic control and aggressive glycated hemoglobin targets <7.0% have failed to show an improvement in cardiovascular mortality. Repetitive and severe hypoglycemic episodes with intensive glucose-lowering therapy may be a major factor in the failure to show cardiovascular benefit in diabetic patients. In this article, the cardiovascular effects of hypoglycemia, and the trials with an intensive glucose-lowering strategy that have studied microvascular and macrovascular complications are discussed. The current non-insulin drugs, which do not induce hypoglycemia, available for the treatment of diabetes and their cardiovascular impacts are clarified.
