Optimized Glycemic Control in Heart Failure Patients With DM2:"Effect on Left Ventricular Function and Skeletal Muscle"

Optimized Glycemic Control in Type 2 Diabetics With Heart Failure:"Effect on Left Ventricular Function and Skeletal Muscle"

The investigators wish to investigate wether a more strict diabetic control improves cardiac function, muscle strength, exercise capacity and decreases symptoms.

The investigators hypothesis is that improving the glycemic control in suboptimized diabetics with heart failure will improve cardiac performance, muscle strength, exercise capacity and decrease symptoms.
