Primary Outcome Measures:
  • Myocardial infarction size as a fraction of left ventricular size [ Time Frame: 48-72 hours ] [ Designated as safety issue: No ]
    Myocardial infarction size as a fraction of left ventricular size at 48-72 hours in patients presenting with an ST segment elevation MI who undergo successful percutaneous coronary intervention.


Secondary Outcome Measures:
  • MI size, extent and transmurality of microvascular obstruction [ Time Frame: 48-72 hours ] [ Designated as safety issue: No ]
    MI size, extent and transmurality of microvascular obstruction measured by MRI

  • MI size normalized to area at risk [ Time Frame: 48-72 hours ] [ Designated as safety issue: No ]
  • Myocardial perfusion at coronary angiography at the completion of PCI (corrected TIMI frame count and myocardial blush grade). [ Time Frame: at completion of PCI, as expected 1 day ] [ Designated as safety issue: No ]
  • Transmurality of infarct (as average percent wall thickness in all segments showing delayed enhancement). [ Time Frame: at 48 - 72 hours and 4 months ] [ Designated as safety issue: No ]
  • Myocardial perfusion(MRI). [ Time Frame: at 48-72 hours and 4 months ] [ Designated as safety issue: No ]
  • Global and regional left ventricular function and left ventricular mass at 48 - 72hours and 4 months after MI and the change in global LV function and mass between 48-72 hours and 4 months. MI size as a fraction of LV size at 4 months after MI. [ Time Frame: 48-72 hours and 4 months ] [ Designated as safety issue: No ]
  • Resolution of ST segment elevation (serial ECGs) as indicated by the decrease in the total ST elevation (in mV) at 4 hours compared with that observed at enrollment. [ Time Frame: at 4 hours ] [ Designated as safety issue: No ]
  • Troponin T levels and CPK-MB area under the curve at 48 hours. [ Time Frame: 48 hours ] [ Designated as safety issue: No ]
  • Change in adverse remodeling parameters (compared with 48-72 hours):changes in LV end-diastolic volume, end-systolic volume, end-diastolic myocardial wall thickness in infarct, peri-infarct and remote areas and in sphericity index. [ Time Frame: 4 months ] [ Designated as safety issue: No ]
    Change in adverse remodeling parameters (compared with 48-72 hours):changes in LV end-diastolic volume, end-systolic volume, end-diastolic myocardial wall thickness in infarct, peri-infarct and remote areas and in sphericity index at end-diastole and end-systole.

  • Death, nonfatal recurrent MI, recurrent ischemia necessitating re-hospitalization, PCI, or surgical revascularization, and stroke (i.e. combined CV endpoint) at 4 months. Enzyme leak during subsequent scheduled PCI will not be considered new ischemia/MI. [ Time Frame: 4 months ] [ Designated as safety issue: No ]
  • Assess the safety of inhaled NO for this use as determined by reported adverse events (including bleeding and laboratory changes). [ Time Frame: during treatment gas period, an average of 6 hours ] [ Designated as safety issue: Yes ]

  6. Active or recent hemorrhage requiring an invasive procedure for evaluation or transfusion within 6 weeks prior to presentation or hemorrhagic stroke within the 6 weeks prior to presentation.
  7. Known or suspected aortic dissection.
  8. Prior history of pulmonary disease requiring chronic oxygen therapy.
  9. Pregnancy, lactating and woman of childbearing potential.
  10. Use of investigational drugs or device within the 30 days prior to enrollment to the study. Investigational uses of approved therapies will be allowed.
  11. Medical problem likely to preclude completion of the study.
