Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The aim of the current study is to evaluate the acute effects of gradual, insulin sparing (GLP-1-based therapy) versus acute (insulin-based therapy) glucose lowering on myocardial lipid content (assessed by MR-spectroscopy) in patients with type 2 diabetes.;Secondary Objective: Changes in •hepato-cellular lipid content •left ventricular function (ejection fraction, end-systolic volume, end-diastolic volume, stroke volume, cardiac output, mass, wall thickness, E/A-ratio) and remodeling-indices •retinal morphology, perfusion and function as measured by Optical Coherence Tomography (SD-OCT) and fluorescein angiography •retinal function measured by microperimetry •biomarkers of endothelial dysfunction •microalbuminuria •beta-cell-function ;Primary end point(s): Changes in myocardial lipid content (assessed by MR-spectroscopy) ;Timepoint(s) of evaluation of this end point: study day 28 | — |
