There is a clear link between diabetes and cardiovascular disease. It is known that cardiovascular diseases in patients with diabetes mellitus occur 2–5 times more often than in people without diabetes. It is cardiovascular outcomes that are the main cause of death in patients with diabetes mellitus in both men and women. Diabetes mellitus has a high risk of coronary heart disease, myocardial infarction, arterial hypertension and acute cerebrovascular accident, and patients with diabetes mellitus may experience painless acute myocardial infarction associated with the presence of autonomic cardiac neuropathy. Various rhythm disturbances are much more common in diabetes mellitus, including paroxysmal forms of atrial fibrillation, which increase the risk of death by 1.8–2 times. The leading factor in the development of vascular complications of diabetes mellitus is hyperglycemia. In addition, early glycemic disorders - impaired glucose tolerance or impaired fasting glycemia - make a significant contribution to the increased risk of macrovascular complications. Improving glycemic control leads to a significant reduction in the risk of late macro- and microvascular complications of diabetes mellitus. Glycated hemoglobin is the gold standard for monitoring glycemic control, but it does not provide complete information on daily and intraday changes in glucose levels. Regular self-monitoring of glucose levels is important in the prevention of cardiovascular diseases in patients with diabetes mellitus. In addition, during the COVID-19 pandemic, all consensus documents and recommendations for the management of patients with diabetes indicate the need for regular monitoring of glucose levels. An important aspect of the technical impact on patients’ adherence to selfcontrol and diabetes therapy is the presence of a convenient communicative connection between the patient and the doctor, in particular, the possibility of contact remotely via a computer and a mobile phone. In conclusion, the possibilities of the new model of the line of blood glucose meters are considered.
