The purpose of this study is to determine if exenatide will improve global cardiac function in patients with type 2 diabetes mellitus and congestive heart failure, by favorable effects on cardiac metabolism leading to improvement of cardiac efficiency.

Primary Outcome Measures:
  • Cardiac Magnetic Resonance (CMR) will be used to assess global cardiac function (LV ejection fraction). [ Time Frame: week -2 and week 11 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Cardiac oxygen consumption, cardiac efficiency and stress perfusion will be assessed by Positron Emission Tomography (PET) using 11C-acetate and H2-15O [ Time Frame: week -2 and week 26 ] [ Designated as safety issue: No ]
  • Cardiac function, dimensions and scarring will be measured bij CMR [ Time Frame: week -2 and week 26 ] [ Designated as safety issue: No ]
  • Myocardial diastolic function parameters will be obtained bij trans thoracal echocardiography. Comparisons will be made of strain and torsion measures obtained bij CMR and echocardiography. [ Time Frame: week -2 and week 26 ] [ Designated as safety issue: No ]
  • Exercise capacity and performance will be assessed by a 6-minute walking test [ Time Frame: week -1 and week 27 ] [ Designated as safety issue: No ]

Enrollment: 27
Study Start Date: May 2009
