Evaluation of Diagnostic Utility of Pentraxin-3 in Acute Coronary Syndrome Patients: A Pilot Study from Tertiary Care Hospital in South India

Abstract

Background: Pentraxin 3 (PTX3), a member of C-reactive protein-like inflammatory protein group, is abundantly expressed in atherosclerotic plaques, as well as in cardiac myocytes. Increased serum PTX3 level has been observed in patients with the acute coronary syndrome (ACS). The diagnostic role of PTX3 in all three types of ACS in the Indian population is limited. This study aimed to investigate whether serum PTX3 can be used as a potential biomarker in the early detection of ACS. Materials and Methods: This is a cross-sectional case-control study comprising of 47 cases and 33 controls. Cases were divided into three groups, out of which 12 patients were of non-ST-segment elevation myocardial infarction (NSTEMI), 23 patients were of ST-segment elevation myocardial infarction (STEMI), and 12 patients were of unstable angina. Patients were recruited within 7 h of post event who are clinically diagnosed as ACS. Lipid parameters were measured on the Roche Cobas c511 analyzer and PTX3 levels were measured by ELISA kit. Results: Serum PTX-3 levels were significantly higher in all three groups of ACS when compared to controls (P
