The use of modern pharmaceuticals and cardiovascular disease (CVD) treatment methods has increased life expectancy and improved the quality of life of both patients with normal carbohydrate metabolism and diabetes mellitus (DM). This study provides a review of the literature on glycaemic control and choice of glucose-lowering therapy in patients with type 2 DM (T2DM) and CVD. According to the latest recommendations for the prevention of CVD, the target level of glycated haemoglobin (HbA1c) should be less than 7.0% and 7.5%–8.0% in older patients to decrease the risk of hypoglycaemia. The target blood glucose level is 7.7–10 mmol/L. The results of randomized clinical trials (RCTs) revealed that the adverse effects of second-generation sulfonylureas include critical hypoglycaemia episodes and increases in CVD-associated complications and mortality. Metformin reduces the risk of CVD in comparison with second-generation sulfonylurea derivates and insulin. Thiazolidinediones are not currently used for patients with CVD, and the safety of GLP-1 analogues and SGLT-2 inhibitors is still under investigation. When metformin therapy is ineffective, DPP-4 inhibitors should be prescribed and renal function should be monitored. Metformin is contra-indicated in patients with severe chronic heart failure (CHF) and acute myocardial infarction (AMI) because of the risk of lactic acidosis with tissue hypoxia. Thus, insulin is the drug of choice for glycaemic control in CVD patients with chronic kidney disease, severe heart failure or other acute clinical conditions.
