| Scientific title | Does sodium nitrite administration reduce ischaemia-reperfusion injury in patients presenting with acute ST segment elevation myocardial infarction? |
| Study acronym | NIAMI |
| Study objectives | 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(s) | First MREC, 2 March 2011, ref:10/MRE00/83 |
| Health condition(s) or problem(s) studied | 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 | Other |
| Primary outcome measure(s) |
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 |
| Key secondary outcome measure(s) |
1. Plasma creatine kinase and Troponin I for 72 hours post MI |
