Differential value of eosinophil count in acute coronary syndrome among elderly patients

We aimed to search eosinophil (EOS) counts in elderly acute coronary syndrome (ACS) subjects and to investigate its value for discrimation between unstable angina pectoris (UAP) and myocardial infarction (MI) [non-ST elevation MI (NSTEMI) or ST elevation MI (STEMI)]. The patients were divided into three groups regarding the diagnosis: patients with UAP (63), with NSTEMI (154), and with STEMI (73). General characteristics such as gender, age, systolic and diastolic blood pressure were obtained from patients' files. Complete blood count and biochemical parameters were measured before coronary angiography. EOS was found significantly higher in UAP (0.134 (0.002-0.746) u/mm
