Brief Summary

An intense inflammatory reaction is triggered by the ischemic injury during myocardial infarction. The inflammatory processes involved are complex and haven't been explored in detail in human patients. This inflammatory response can increase myocardial damage following reperfusion, leading to adverse remodeling and adverse events (heart failure, sudden cardiac death). Cardiac MRI can assess the size of myocardial infarction and many other parameters associated with myocardial injury: edema, hemorrhage, micro-vascular obstruction. (However the association between biomarkers of inflammation and these imaging parameters is not known). There is very little data correlating imaging markers of myocardial injury to the biokinetics of inflammation biomarkers. In this study, the aim is to assess the relationship between the kinetics of specific inflammatory biomarkers (interleukin-1beta, interleukin 6, interleukin 17, Tumor Necrosis Factor (TNF)-alpha, C reactive protein (CRP), soluble toll-like receptor-2 (ST2), neutrophils) and imaging markers of injury measured by cardiac MRI at the acute phase in 20 acute mycardial infarction (AMI) patients.

  • This study confirms the strong association between infarct size and CRP levels, but does not demonstrate any significant relationship with the other biomarkers investigated (IL-6, IL-8, and IL-10). Among the three markers of myocardial injury assessed, myocardial hemorrhage appears to be strongly associated with the release of inflammatory biomarkers following reperfused STEMI. Attenuation of reperfusion-induced hemorrhage may therefore represent a novel therapeutic target for future adjunctive treatments in STEMI patients. Additional cytokine measurements are currently being performed to further refine the assessment of the relationship between hemorrhage, infarct size, and other inflammatory biomarkers.
