Trial Title: Preventing Contrast-induced Nephropathy: Evaluating Hydration Strategies and L-carnitine Administration

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: FACTORIAL
- Observational Model: None
- Primary Purpose: PREVENTION
- Time Perspective: None
- Masking: NONE
- Phase: PHASE3
- Number of Arms: 4.0

Eligibility Criteria:
Inclusion Criteria:~* The patient must have given his/her informed and signed consent~* The patient must be insured or beneficiary of a health insurance plan~* The patient is scheduled for a coronarography~* The patient can come back to the hospital on days 2 and 7 after the coronarography for follow up~* The patient has moderate to severe renal insufficiency (glomerular filtration rate \< 60 ml / min / 1.73 m\^2)~* The patient has not had any oral antidiabetic treatments, or diuretic treatments, within 48 hours preceding the coronarography~* Lack of treatment with ACE inhibitors or ARA2 24 hours prior to coronary~Exclusion Criteria:~* The patient is participating in another study~* The patient is in an exclusion period determined by another study~* The patient is under judicial protection~* The patient is under any kind of guardianship~* The patient refuses to sign the consent form~* It is impossible to correctly inform the patient~* The patient is unable to participate in follow-up visits at days 2 and 7 after the coronarography~* The patient is pregnant or breastfeeding~* The patient is taking L-carnitine~* The patient has a contra indication for a treatment used in this study~* Acute heart failure~* Infarction, acute phase~* Hemodialysis patient~* Myeloma~* Epileptic patient treated with Depakine (valproic acid) (carnitine can lower epilepsy-related thresholds by speeding up the metabolism of Depakine)

Study Arms:
- Bicarbonate (Type: EXPERIMENTAL): The patients included in this arm will be administered a hydration regime for the prevention of contrast-induced nephropathy containing sodium bicarbonate.~Intervention: Hydration strategy using sodium bicarbonate Intervention: Coronarography
- Saline (Type: ACTIVE_COMPARATOR): The patients included in this arm will be administered a hydration regime for the prevention of contrast-induced nephropathy using sodium chloride solution.~Intervention: Hydration strategy using saline Intervention: Coronarography
- Bicar + L-Carnitine (Type: EXPERIMENTAL): The patients included in this arm will be administered a hydration regime for the prevention of contrast-induced nephropathy containing sodium bicarbonate. They will also receive an oral L-carnitine solution on days -1, 0, 1 to 7.~Intervention: Hydration strategy using sodium bicarbonate Intervention: L-carnitine Intervention: Coronarography
- Saline + L-carnitine (Type: EXPERIMENTAL): The patients included in this arm will be administered a hydration regime for the prevention of contrast-induced nephropathy using sodium chloride solution. They will also receive an oral L-carnitine solution on days -1, 0, 1 to 7.~Intervention: Hydration strategy using saline Intervention: L-carnitine Intervention: Coronarography
