Study information
Scientific title
Does sodium nitrite administration reduce ischaemia-reperfusion injury in patients presenting with acute ST segment elevation myocardial infarction?
Acronym
NIAMI
Study hypothesis
Does a 2.5 - 5 minute systemic intravenous injection of sodium nitrite administered immediately before opening of the infarct related artery result in significant reduction of ischaemia reperfusion injury in patients with first acute ST elevation myocardial infarction (MI)?
Where possible, written consent will be sought prior to the intervention. However in the emergency setting, verbal agreement will be sought from eligible patients.
Ethics approval

Condition
Cardiovascular Disease: Coronary Artery
Intervention
1. Treatment: sterile solution containing 70 micromol sodium nitrite dissolved in 5ml water injected intravenously over 2 and a half to 5 minutes
2. Placebo: sterile solution containing 0.9%w/v sodium chloride in 5ml water injected intravenously over 2 and a half to 5 minutes
3. The active treatment and placebo will look identical so that patients and clinical staff remain blind to the allocation
4. Followed up after 6 months
Intervention type

Phase
Phase II/III
Drug names
Primary outcome measures
The difference in final infarct size between sodium nitrite and placebo groups both measured using MRI between 10-14 days following the acute myocardial infarction and corrected for area at risk
Secondary outcome measures
1. Plasma creatine kinase and Troponin I for 72 hours post MI
2. LV ejection fraction measured by MRI between days 10-14
3. LV ejection fraction measured by MRI at 6 months
4. LV end systolic volume index
