A number of inflammatory markers have been recognized, among which the acute phase reactant C-reactive protein showed a positive correlation with the risk of coronary artery disease in both healthy individuals and those at high risk .~Pentraxin 3 is expressed in atherosclerotic plaques, mainly in macrophages and neutrophils, suggesting that pentraxin 3 may be involved in the progression of atherosclerotic plaque.~A number of studies demonstrated that increased levels of Pentraxin 3 were associated with the presence and increased severity of coronary artery disease in clinically stable patients undergoing elective coronary angiography .~Pentraxin 3 levels peak at about 7 h after acute MI, which is substantially earlier than CRP, and thus PTX3 could be a better independent predictor of CHD than CRP .~Recently, it was shown that the number of the involved vessels, MI type, stent length, culprit lesion, and the need for PCI all had a significant relation with abnormal Pentraxin 3 levels , however, it was not studied with respect of its relation with postprocedural angiographic and clinical outcomes.~We thought to evaluate the role of pentraxin-3 on the preprocedural determinants (Grace score, type of MI, culprit lesion, lesion length, pre-procedural TIMI flow, thrombus burden, severity and complexity of CAD as determined by Syntax score and procedural outcome (post-procedural TIMI flow, no reflow and myocardial perfusion assessed by myocardial blush grade as well as the inhospital clinical outcome of primary Percutaneous coronary intervention in patients with acute ST elevation myocardial infarction.
