Cardiovascular diseases remain a leading cause for unfavorable outcomes, including death, in patients with type 2 diabetes mellitus (DM2). In the recent decade, novel drugs, including glucagon-like peptide-1 receptor agonists (GPP-1-RA) and sodium-glucose cotransporter-2 inhibitors, have convincingly demonstrated their ability to reduce risk of cardiovascular complications in patients with DM2. This review discusses one of GPP-1-RA, semaglutide, with a special focus on the evidence-based data on its use, cardioprotective properties, and algorithms of administration consistent with current clinical recommendations.
