Core Tip

Core Tip: Cardiovascular disease is the major cause of morbidity and mortality among patients with diabetes mellitus (DM). Three distinct and common clinical entities viz., coronary artery disease (CAD), cardiac autonomic neuropathy (CAN) and diabetic cardiomyopathy (DCM) collectively form diabetic heart disease. The pathophysiological mechanisms involved in the development of diabetic heart disease are complex and involve multiple metabolic and molecular pathways. Although most clinicians are well-aware that CAD is a cardiac complication of DM, the awareness about CAN and DCM is remarkably low. This clinical update discusses the pathophysiology, diagnostic aspects, and management options for patients with diabetic heart disease, to empower clinicians across the globe to optimally manage the disease scientifically.
