Aims: Glucagon-like peptide-1 (GLP-1), a gastrointestinal hormone mainly produced in the post-prandial. state, reduces blood glucose through the stimulation of insulin secretion and the inhibition of glucagon release. Long-acting GLP-1 receptor agonists, and dipeptidyl-peptidase-4 (DPP-4) inhibitors which increase GLP-1 levels, are used as hypoglycemic treatments in type 2 diabetes. This paper aims at reviewing the potential benefit of those treatments in the prevention of cardiovascular risk in type 2 diabetic patients. Data synthesis: Experimental studies have shown that GLP-1 has several potentially beneficial actions on cardiovascular risk. Some of those, such as protection from myocardial ischemic damage and improvement of cardiac function, have also been demonstrated in humans. However, the equivalence of GLP-1 agonists and DPP-4 inhibitors with GLP-1, with respect to cardiovascular risk profile, cannot be assumed or taken for granted. Drugs of those two classes have been shown to effectively reduce glycated hemoglobin and to have a specific effect on post-prandial glucose; furthermore, they seem to reduce blood pressure and to have some favorable effects on lipid profiles. Additionally, GLP-1 agonists induce weight loss in diabetic patients. Conclusion: The profile of action of GLP-1 receptor agonists and DPP-4 inhibitors suggests the possibility of an actual reduction in cardiovascular risk, which needs to be confirmed by large tong-term clinical trials.
