Overview

Cardiovascular risk reduction is the major aim of type 2 diabetes mellitus treatment. The effects of various antidiabetics on the cardiovascular complications are currently under careful scrutiny. Incretin-based therapy that utilizes the effects of glucagon-like peptide 1 (GLP-1) or stimulation of its receptor by GLP-1 receptor agonists represents one of the most promising approaches from the potential cardiovascular risk reduction point of view. Experimental studies have shown that the GLP-1 and GLP-1 agonists treatment improves endothelial function, decrease blood pressure and protects myocardium during experimentally-induced ischemia. Clinical studies with GLP-1 receptor agonists consistently show that, in addition to good antidiabetic efficacy, its long-term administration decreases blood pressure, body weight and improves circulating lipid levels while slightly increasing heart rate. In this paper, we focus on the cardiovascular effects of GLP-1 receptor agonist liraglutide. Preliminary analyses of cardiovascular complications in phase III trials with liraglutide indicate its good cardiovascular safety. A possibility of cardioprotective effects of liraglutide remains still open and is currently studied within a prospective cardiovascular trial LEADER.

Key words:
cardiovascular complications – diabetes mellitus – GLP-1 agonists – glucagon-like peptide 1 – liraglutide
