Although appropriate diagnostic methods have been introduced for ACS, it still remains a challenge for physicians. Therefore, utilizing additional markers and ratios for the diagnosis of ACS can be beneficial. Hence, our study was conducted with the aim of evaluating the diagnostic value of indices and ratios derived from the complete blood count (CBC) test.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      In this retrospective diagnostic accuracy study, 360 patients presenting with acute chest pain to the emergency department of Allameh Bohlool Hospital were evaluated.

CBC\u2010derived parameters, including leukocyte count, neutrophil count, monocyte count, platelet count, mean platelet volume (MPV), neutrophil\u2010to\u2010lymphocyte ratio (NLR), monocyte\u2010to\u2010lymphocyte ratio (MLR), and platelet\u2010to\u2010lymphocyte ratio (PLR), were assessed. Diagnostic performance was evaluated using receiver operating characteristic (ROC) curve analysis.
