Diabetic myocardial disease: pathophysiology, early diagnosis and therapeutic options.
Diabetes mellitus is a powerful risk factor for cardiovascular disease associated with high morbidity and mortality rates. Diabetic patients also have an increased incidence of heart failure which has been traditionally attributed to the concurrent presence of ischemic or hypertensive heart disease. Yet, nowadays, according to recent scientific evidence, diabetic myocardial disease (DMD) is more and more being considered as a distinct nosologic entity, independent of the co-existence of coronary artery disease, arterial hypertension or other risk factors, with the potential to lead to a self-existent progressive development of heart failure. In this article, we review the possible pathophysiologic mechanisms involved in the development of DMD as well as the structural and functional changes in the diabetic heart. We emphasize the importance of early detection of the syndrome, especially by novel echocardiographic techniques. Finally, we refer to the various therapeutic options for the optimal management of DMD according to the recent literature.
