  Purpose

Primary Hypothesis: Prophylactic Vitamin C Intravenous Infusion at the time of percutaneous coronary intervention (PCI) would limit the size of the infarct, assessed by measurements of cardiac biomarkers, during acute myocardial infarction.

Secondary Hypotheses: Prophylactic Vitamin C Intravenous Infusion at the time of percutaneous coronary intervention (PCI) would limit the size of the infarct, as measured by the area of delayed hyperenhancement that was seen on cardiac magnetic resonance imaging (MRI), assessed on day 5 after infarction, during acute myocardial infarction.

Primary Outcome Measures:
  • Specific key observations used to measure the effect of experimental treatment in this study are the incidence of Major Adverse Cardiovascular Events. [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    Cardiovascular Death, Myocardial Infarction, Stent Thrombosis, Repeat Revascularization, Stroke, Transient Ischemic Attack

  • Size of the infarct, assessed by measurements of cardiac biomarkers. [ Time Frame: 3-5 days ] [ Designated as safety issue: Yes ]
    Prophylactic Vitamin C Intravenous Infusion at the time of percutaneous coronary intervention (PCI) would limit the size of the infarct, assessed by measurements of cardiac biomarkers, during acute myocardial infarction.


Secondary Outcome Measures:
  • Size of the infarct assed by cardiac magnetic resonance imaging [ Time Frame: 5 days ] [ Designated as safety issue: No ]
    Prophylactic Vitamin C Intravenous Infusion at the time of percutaneous coronary intervention (PCI) would limit the size of the infarct, as measured by the area of delayed hyperenhancement that was seen on cardiac magnetic resonance imaging (MRI), assessed on day 5 after infarction, during acute myocardial infarction.

Arms Assigned Interventions
Active Comparator: Vitamin C Drug: Vitamin C
After baseline collection of blood samples, computer-generated random sequence were used for randomization to an intravenous infusion of vitamin C (1 g/L of saline solution at 24 mg/min) or placebo(saline solution) during intervention. Less than 10 minutes before direct stenting, the patients received the intravenous infusion.
Placebo Comparator: Placebo Drug: Placebo
After baseline collection of blood samples, computer-generated random sequence were used for randomization to an intravenous infusion of vitamin C (1 g/L of saline solution at 24 mg/min) or placebo(saline solution) during intervention. Less than 10 minutes before direct stenting, the patients received the intravenous infusion.

Detailed Description:

This is a multicenter, prospective, controlled, randomized study that will be conducted at up to 5 centers in Italy. All patients who meet the eligibility criteria will be randomized to receive during surgical procedure an intravenous infusion of Vitamin C or Placebo.

Patients will have repeat clinical follow-up to 5 days, 3 and 6 months and 1 year.

The new angiography evaluation will be done if necessary. The study population will consist of at least 100 patients who presented within 12 hours after the onset of chest pain, who had ST-segment elevation of more than 0.1 mV in two contiguous leads, and for whom the clinical decision was made to treat with percutaneous coronary intervention (PCI). Following confirmation of eligibility criteria, patients will be randomized in a 1:1 ratio to receive prophylactic infusion of Vitamin C or Placebo. The coronary angiograms will be assessed at a core laboratory with Quantitative Coronary Angiography.

The incidence of clinical events, including death, myocardial infarction, target vessel revascularization, stent thrombosis, will be evaluated at 1, 3, 6 and, 12 months.
