Diabetes and cardiovascular diseases

Diabetes mellitus represents a global health challenge characterized by a continuous increase in prevalence and a substantial impact on population morbidity and mortality. Cardiovascular diseases are the most common and clinically significant chronic complication of diabetes, accounting for more than half of all deaths among affected individuals. The increased cardiovascular risk in patients with diabetes results from a complex interaction of metabolic, hemodynamic, inflammatory, and proatherogenic mechanisms that lead to structural and functional alterations of the vascular endothelium, accelerated atherosclerosis, and progressive cardiovascular damage.Chronic hyperglycemia, insulin resistance, dyslipidemia, arterial hypertension, oxidative stress, and systemic inflammation are key pathophysiological factors contributing to the development and progression of coronary artery disease, cerebrovascular disease, peripheral arterial disease, and heart failure. The contemporary approach to diabetes management extends beyond glycemic control alone and is focused on comprehensive reduction of overall cardiovascular risk through a multifactorial strategy.Recent decades have been marked by significant advances in understanding the cardiometabolic relationship between diabetes and cardiovascular disease, as well as by the development of evidence-based therapeutic strategies. Particular attention has been directed toward novel antihyperglycemic agents which, in addition to their metabolic benefits, have demonstrated the ability to reduce major cardiovascular events, slow the progression of heart failure, and improve overall survival. Timely risk assessment, early diagnosis, and an individualized therapeutic approach are essential prerequisites for optimizing clinical outcomes.
