Detailed Description
Diabetes is a serious and increasing global health burden. It has been shown, that diabetes is associated with a two-fold higher risk for coronary heart disease, stroke and for the aggregate of other vascular death independently of other conventional risk factors. It is the leading cause of cardiovascular disease.
Diabetes mellitus substantially increases the risk of macrovascular and microvascular complications, such as vascular dysfunction with developing coronary, cerebrovascular, and peripheral arterial disease, heart failure, nerve disorders (neuropathy), eye complications (e.g. cataracts, glaucoma diabetic retinopathy), kidney disease (nephropathy), foot ulcers, restriction of mental function, and psychosomatic diseases (e.g. stress, anxiety and depression).
The most common of the cardiovascular complications in diabetics are ischemic cardiomyopathy and left ventricular (LV) dysfunction. Of particular interest here is the diastolic dysfunction, as an early sign of diabetic heart muscle disease followed by systolic damage.
Although diabetes has a decisive role in the development of cardiovascular disease, traditional glucose lowering agents have failed to convincingly show that intensive glucose control significantly reduces CVD events.
A new approach for treatment of adult patients with type 2 diabetes was found with the selective inhibition of sodium glucose cotransporter 2 (SGLT2). Studies have shown that empagliflozin, a potent SGLT2 inhibitor, not only effectively reduces the rates of hyperglycemia but also blood pressure and weight. (16, 18) In addition, beneficial effects on arterial stiffness and vascular resistance, visceral adiposity, albuminuria and plasma urate have been reported.
The results of the EMPA-REG OUTCOME study suggest that empagliflozin added to the standard therapy has a positive influence on cardiovascular outcomes and heart failure hospitalization in individuals with diabetic mellitus.
The aim of the present study is to investigate the effects of empagliflozin, in comparison with placebo, on cardiac and vascular function as well as on cardiac biomarker in individuals with type 2 diabetes with standard therapy, increased E/E' ratio and poor glycemic control.
