Background: Lipoprotein (a) [Lp (a)] is an independent cardiovascular risk (CVR) both in the general population and in patients with type 2 diabetes mellitus (DM-2). Until now no effective treatment is known to decrease the levels of Lp (a) levels and thus achieve a reduction of CVR. Among the new antidiabetic drugs are GLP-1Receptor agonists(GLP-1R). In addition to lowering blood glucose, these drugs have other beneficial effects. In our laboratory we have demonstrated that both native GLP-1 and various GLP-1R agonsits reduce the synthesis of Lp (a) in hepatocytes.
