Comparative Study of Potential Diagnostic Biomarkers in Myocardial Infarction with Survival and Myocardial Infarction without Survival

Abstract

Introduction Because of the varied presentation and associated high mortality, the identification of patients with acute myocardial infarction (MI) is very critical for patient management and has a bearing on the prognosis. The goal of present study was to correlate the diagnostic value of cardiac biomarkers in MI with survival and MI without survival. Materials and methods Diagnostic case—control study was conducted on 110 MI patients presenting to the Emergency Department within 12 hours of acute chest pain, and 120 healthy age- and sex-matched volunteers formed the control group. Serum ischemia-modified albumin (IMA), troponin I (TnI), creatine kinase-MB (CK-MB), lactate dehydrogenase (LDH), and aspartate transaminase (AST) were measured. Statistical software SYSTAT version 12 was used to analyze the data. The results were expressed in mean ± standard deviation. Comparisons of study groups and study groups with control groups were done by applying Z test. Correlation was tested by Student's t-test at 5% (p = 0.05) and 1% (p = 0.01) level of significance. Results Mean levels of serum IMA, TnI, CK-MB, LDH, and AST levels were significantly higher (p < 0.01) in patients with MI as compared with healthy controls. Serum levels of cardiac biomarkers were significantly elevated (p < 0.01) in MI patients without survival as compared with MI with survival. Conclusion The serum levels of biomarkers were increased in MI without survival as compared with MI with survival. These study data prove that these changes might be helpful to obtain a comprehensive view of the infarct size and severity of vascular stenotic lesions.
