no patient recruitment

The heart has the ability to respond to different patho-physiological conditions by adapting its energy metabolism. In diabetic subjects, the myocardium uses only fatty acids as a substrate. This is the cause of diabetic cardiomyopathy (DCM). The activation of the transcription factor PPARβ/δ allows a good use of fatty acids. The staff have demonstrated that alpha lipoic acid (AαL), a molecule with antioxidant properties present in food supplements and in certain foods (broccoli, cabbage, offal...), induces the expression of PPARβ/δ in skeletal muscle and thus increases the activity of this transcription factor.

Inclusion Criteria:

• Male or female adult age ≥ 18 years
• patient with diagnosed type 2 diabetes (history of pathological hyperglycemia according to WHO and HbA1c standards >7% or ongoing treatment with oral antidiabetic agents).
• Patients with stable cardiomyopathy (no hospitalization in cardiology in the month before inclusion) with a left ventricular ejection fraction (LVEF) <50%.
• patient who has signed an informed consent form
• For women of childbearing age: effective contraception followed for at least 3 months before the start of the study and agreeing to keep it for the duration of the study.
• affiliation to a social security scheme.

Exclusion Criteria:

subjects:

• With a coronary event in the year before inclusion.
• With symptoms of cardiac ischemia at inclusion.
• Pregnant or breastfeeding woman
• Severe renal insufficiency
• Using antioxidant molecules in the 6 months prior to inclusion.
• Using drugs that can activate PPARs (Fibrates, Telmisartan, Enalaprilat).
• Using anti-inflammatory drugs.
• Suffering from acute infectious diseases and inflammatory diseases.
• Hypersensitivity or a history of hypersensitivity reaction to gadoteric acid, meglumine or any drug containing gadolinium.
