Brief summary
Primary objective: To demonstrate that in hyperglycemic subjects with anterior STEMI (ST Elevation Myocardial Infarction) undergoing Percutaneous Coronary Intervention (PCI), tight glycemic control using insulin glulisine and insulin glargine, i.e. Intensive Insulin Therapy (IIT), results in reducing infarct size at day 60 versus (vs) Standard Glycemic Care (SGC). Secondary objectives: To demonstrate that tight glycemic control using insulin glulisine and insulin glargine reduces markers of inflammation and improves Left Ventricular (LV) function and Cardio-Vascular (CV) outcomes from baseline values, in hyperglycemic subjects with STEMI undergoing Percutaneous Coronary Intervention (PCI).
Interventions
Subcutaneous insulin glargine was initiated 90 prior to the insulin glulisine infusion discontinuation (i.e. 48 hours after randomization) and titrated as per physician preference to maintain the plasma glucose between 90-130 mg/dL
Prior PCI, subjects received a single IV bolus of insulin glulisine. The dose was 0.025 U/kg based upon patient reported weight. Then IV insulin glulisine infusion was started within one hour of the IV insulin glulisine bolus and administered at a minimum rate of 2 U/h for 48 hours. The infusion was titrated in order to achieve and maintain the plasma glucose between 90 and 130 mg/dL.
Standard insulin therapy titrated to blood sugar control

Eligibility
Inclusion criteria

Exclusion criteria
* A prior history of Myocardial Infarction (MI) * Subjects who have received any thrombolytic therapy during the current hospital admission * Severe Heart Failure or cardiogenic shock (Killip class 3 or 4) by history or present at the time of screening * Subjects with a plasma glucose \>400 mg/dL or diabetic ketoacidosis (DKA) * History of Type 1 diabetes * Active bleeding * Active malignancy, chronic or other medical conditions likely to result in death over the next one year * Recent hypotension requiring inotropic support in the past 30 days * Participation in another clinical research study in the past 30 days * Pregnant or lactating women (women of childbearing potential must have a negative pregnancy test at study entry and a medically approved contraception method) * Unwilling to give informed consent * Subjects directly involved in the conduct of the study * Known hypersensitivity to insulin glargine or glulisine * Contraindication to MRI: a)Intracranial aneurysm clips (Unless the investigator is certain that it is made of non-ferromagnetic material such as titanium)b)Intra-orbital metal fragments c)Any electrically, magnetically or mechanically activated implants (including cardiac pacemakers, biostimulators, neurostimulators, cochlear implants, and hearing aids) d)Warning about Gadolinium-based contrast agents (GBCAs) Exposure to GBCAs increases the risk for nephrogenic systemic fibrosis (NSF). Therefore the following subjects should be excluded from the trial based on a history and/or laboratory tests: * acute or chronic severe renal insufficiency (glomerular filtration rate \<30 mL/min/1.73m2), as calculated by the MDRD (Modification of diet in Renal Disease) equation, or * acute renal insufficiency of any severity * Subjects with blood pressure \> or = to 200/110 mmHg at time of randomization * Subjects with a high degree of non-transient AV (Atrio-Ventricular) block The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.

Participant flow
Recruitment details
Multicenter study: 60 out of the 90 centers planned were initiated. Only 17 centers randomized patients (i.e. 7 sites in the United States, 5 sites in Argentina, 3 sites in Brazil and 2 sites in Mexico).
Pre-assignment details
Although 34 patients signed the informed consent form for study inclusion, one patient did not sign the Health Insurance Portability and Accountability Act (HIPAA) form, electing to keep his/her medical information private, and was therefore not randomized.
