ABSTRACT
OBJECTIVE: Our aims were to determine whether the levels of plasma monocyte chemotactic protein-1 (MCP-1), fetuin-A, serum total antioxidant status (TAS), and serum total oxidant status (TOS) are cardiac biomarkers and to clarify their relationship with each other in acute myocardial infarction (AMI). PATIENTS AND METHODS: The study included 90 participants: 60 patients with AMI [30 with and 30 without ST-segment elevation myocardial infarction (STEMI)] and 30 cardiac patients without AMI. The diagnostic values of serum Hs-cTnT, MCP-1, fetuin-A, TAS, and TOS levels in predicting AMI were evaluated statistically. RESULTS: Median levels of MCP-1 [120.10 ng/L (interquartile range: 76.94-230.54 ng/L)] and TOS [2.89 U/MI (IQR: 2.31-3.94 U/Ml)] were statistically higher, and median levels of fetuin-A [433.52 mg/L (IQR: 387.89-584.49 mg/L)] and TAS (3.10 ± 0.86 U/mL) were lower in patients with AMI than in controls. The parameter with the area under the curve (0.815), sensitivity (73.3%), and specificity (66.7%) closest to those of Hs-cTnT was fetuin-A, followed by MCP-1, TOS, and TAS, respectively. A one-unit increase in MCP-1 levels increased the probability of AMI by 1.023 times (p = 0.002). A one-unit increase in fetuin-A levels decreased the probability of AMI by 0.995 times (p = 0.003). A one-unit increase in serum TOS levels was 1.29 times more characteristic of STEMI than of NSTEMI (p = 0.044). CONCLUSIONS: MCP-1, oxidative stress parameters, and fetuin-A might support Hs-cTnT levels in the early diagnosis of AMI. Fetuin-A and MCP-1 levels may be independent risk factors for AMI, whereas TOS could be used to distinguish STEMI from NSTEMI.
