Modulation of Free Fatty Acids in Heart Failure Patients With Diabetes: "Effect on Left Ventricular Function" (Metamod3)

January 18, 2013 updated by: University of Aarhus

Short Term Modulation of Circulating Free Fatty Acids in Heart Failure Patients With Type 2 Diabetes: "Effect on Myocardial Lipid Content, Left Ventricular Function and Exercise Capacity"

The investigators wish to investigate the the short term effect of low circulating free fatty acids in congestive heart failure patients with type 2 diabetes.

Hypothesis: Low levels of circulating free fatty acids decrease myocardial and peripheral muscle lipid content, improves cardiac performance and exercise capacity.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: High circulating free fatty acids
using Heparin af intralipid infusion for 8 hours
Other: Metabolic substrate modulation
for high circulation free fatty acids: Heparin (250IE/hour) + intralipid (20%, 62 ml/hour).
Active Comparator: Low circulation free fatty acids
using hyperinsulinaemic euglycemic clamp for 8 hours
Other: metabolic substrate modulation
low circulating free acids: hyperinsulinaemic euglycemic clamp (0,8 mUkg/min) with venous blood glucose at 4,5-6,5 mM.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Left ventricular function
Time Frame: 1-6 weeks

Left ventricular systolic function (Ejection fraction, tissue velocity, Strain and strain rate).

Left ventricular diastolic funtion (E/A ratio, E/e' ratio, IVRT) Cardiac output. All parameters measured at rest and peak exercise and outcome is difference between low and high ciculating free fatty acids.
1-6 weeks
intracellular lipid content
Time Frame: 1-6 weeks

Magnetic Resonans proton spectroscopy (septal myocardial intracellular lipid content) Magnetic Resonans proton spectroscopy (Tibialis anterior muscle intracellular lipid content).

Outcome is difference between low and high ciculating free fatty acids.
1-6 weeks
Exercise capacity and oxygen consumption
Time Frame: 1-6 weeks
Using treadmill and continues oxygen consumption measurement. Outcome is difference between low and high ciculating free fatty acids.
1-6 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Regional left ventricular function
Time Frame: 1-6 weeks
regional speckle tracking during rest and peak exercise. Outcome is difference between low and high ciculating free fatty acids.
1-6 weeks
6 minutes hall walk test
Time Frame: 1-6 weeks
distance difference between low and high levels of circulating FFA. Outcome is difference between low and high ciculating free fatty acids.
1-6 weeks
metabolic and hormonal profile
Time Frame: 1-6 weeks
bloodsamples
1-6 weeks
