Brief Summary

Patients with type 2 diabetes (T2 DM) have a markedly increased risk of heart disease and it is estimated that, in the danish population, up 80% percent of patients with type 2 diabetes die from heart disease.

The sodium glucose cotransport-2 (SGLT-2) inhibitors were developed as an anti-diabetic therapy reducing blood glucose and weight by decreasing glucose reabsorption in the kidneys, leading to glucose excretion via the urine. However, in 2015 the EMPA-REG study showed that treatment with the SGLT-2 inhibitor empagliflozin significantly reduced the cardiovascular mortality and risk of admission under the diagnosis of heart failure in a population of patients with type 2 diabetes in addition to other risk factors for heart disease. The mechanism behind this surprising result is unknown and warrants further study.

The primary hypothesis of the present study is that treatment with empagliflozin improves the function and blood supply of the heart muscle cells in patients with type 2 diabetes and high risk of heart disease. The investigators will test this hypothesis by enrolling 92 participants with type 2 diabetes and other risk factors for heart disease, and treating them with either empagliflozin or a placebo. During the study period the investigators will monitor the effects of the treatment with various techniques such as heart scans using CT and ultrasound, measurements of the fluid pressures in the heart chambers, body composition measurements and a variety of relevant blood test.
