Abstract: Enhanced systemic inflammatory activity (SIA) during myocardial infarction (MI) and the extent of the peri-infarct zone characterized by cardiac magnetic resonance imaging (CMRi) are both associated with increased risk of life-threatening arrhythmias and sudden cardiac death. The present study investigated the existence of association between these two phenomena in 98 patients (55±10 years) with ST segment elevation MI. Plasma levels of C-reactive protein (CRP), interleukin-2 (IL-2), and tumor necrosis factor (TNF) were measured on admission (D1) and on the fifth day post-MI (D5). CMRi was performed 2 weeks after MI to quantify peri-infarct zone (PIZ). Between D1 and D5, the increase in CRP (6.0 vs. 5.6 times; p=0.02), IL-2 (3.6 vs. 3.4 times; p=0.04) and tumor necrosis factor type α (TNF-α; 4.6 vs. 3.9 times; p=0.001) were higher in patients with PIZ above the median than in the counterparts. PIZ was correlated with CRP-D5 (r=0.69), delta-CRP (r=0.7), IL-2-D5 (r=0.5), delta-IL-2 (r=0.6), TNF-α (r=0.5), delta-TNF-α (r=0.4; p=0.0001). Enhanced activation of SIA during the acute phase of MI is directly related with generation of PIZ. © 2013 Springer Science+Business Media.
