Comparison of Pentraxin-3 and Ischemia-Modified Albumin with Troponin in Early Diagnosis of Acute Coronary Syndrome

Abstract

INTRODUCTION: In this study, our aim was to evaluate clinical utilities of Pentraxin 3 (PTX3) and Ischemiamodified Albumin (IMA) in diagnosis of acute coronary syndrome (ACS) and compare these two biomarkers with a conventional diagnostic marker, cardiac troponin I (cTnI). MATERIALS AND METHODS: Sixty adult patients with ACS diagnosis were involved into this prospective study. Addi tionally, 20 healthy subjects were determined as control group (Group IV). Patients were divided into 3 groups as follows: Patients with Acute Myocardial Infarction (STEMI Group, n=20, Group I), patients without ST elevation but with elevated cTnI levels (NSTEMI Group, n=20, Group II), and patients with unstable angina pectoris (USAP Group, n=20, Group III). Blood measurements were obtained for each marker at admission and in the 4th hour. RESULTS: Troponin level was significantly different between groups I and II at both admission and in the 4th hour. Additionally, PTX 3 level was significantly different at admission and 4th hour between groups II and III. CONCLUSION: This study revealed that cTnI is the most sensitive test in ACS diagnosis at the admission to Emergency Department. Our results also revealed that PTX 3 may be a useful diagnostic tool for ACS at admission, however, IMA alone cannot be used for diagnosis of ACS. Similarly, in the 4th hour, cTnI was found to be the most useful marker in ACS diagnosis, however, PTX 3 and IMA were found to be inadequate for diagnosis of ACS. © 2018, Comenius University.
