Aim: Inflammation and some infectious agents play a key role in acute coronary syndrome (ACS) caused by atherosclerosis. The purpose of this study was to assess the effects of inflammatory markers and the positivity of Chlamydia pneumoniae (CP), Helicobacter pylori (HP), and Cytomegalovirus (CMV) on the level of atherosclerosis in patients with ACS.Materials and Methods: Patients (57) that were referred to the emergency unit with classic angina symptoms or angina equivalent symptoms and were determined to have critical lesions in the coronary angiography (>70% stenosis, coronary artery disease (CAD) severity assessed by the Gensini score) were compared with 27 ACS patients who had no critical lesions in terms of procalcitonin (PCT), tumor necrosis factor-alpha (TNF-α), interleukin-2 receptor (IL- 2r), interleukin-6 (IL-6), and interleukin-10 (IL-10) levels and positivity of CP, HP, and CMV. Also, the two groups of ACS patients were compared in terms of cytokine levels measured at hours 0 and 48.Results: No significant association was found between the degree of the coronary lesion and the inflammatory and infectious agents. However, in patients with critical coronary lesions, as markers of inflammatory agents, the levels of IL-6 were significantly lower and levels of IL-10 were significantly higher (p
