Abstract

The NAIMI trial has recently been published. It assessed one of the most contemporary and challenging issues in the management of acute myocardial infarction (AMI), namely prevention of reperfusion injury (RPI) after primary PCI for ST-elevation myocardial infarction (STEMI). It investigated the effect of the intravenous administration of Na nitrite given immediately prior to primary PCI for STEMI in 229 patients (118 in the treatment group, and 111 in placebo). The myocardial infarction (MI) size did not differ between the two groups as observed by cardiac MRI (CMR) with gadolinium enhancement at 6–8 days or plasma Troponin-I and creatine kinase (CK), or by left ventricular (LV) volume and ejection fraction (EF) as measured by echocardiography at 6–8 days and again at 6 months. They concluded that IV nitrites did not reduce the infarct size. There was, however, a trend towards benefit in diabetic patients in the post-hoc analysis. The small number of these subjects has probably lead to inconclusive outcome in this subset.
